Mobius Maxi 4K Camera User manual

User Guide for the Mobius Maxi 4K ActionCam
Description
The above picture shows the arrangement of the user operating features.
►This manual does not cover replacing the internal battery or lens.
►This manual assumes the camera is loaded with the latest firmware available at the time
of writing. Functionality may vary with earlier or later firmware versions.
►A more detailed manual can be downloaded from the official Mobius website at
https://mobiusactioncam.com/maxi4k/.
Cards
You should always use micro SDHC or Micro SDXC cards with an UHS speed class rating
of U3 and/or a video speed class rating of V30, V60 or V90. Both FAT32 and exFAT are
supported, but it is recommended to always format cards with a capacity above 32GB in
exFAT. In-Camera Formatting (see below) will do this automatically.
Although it is recommended to use cards with a capacity of 64G or 128GB, cards with a
capacity of up to 1TB have been tested.
Clips recorded on cards formatted in exFAT can be recorded as max. 60GB clips. Clips
recorded on cards formatted in FAT32 can be recorded as max. 4GB clips.
If a specific card does not work correctly after it has been freshly formatted you should no
longer use the card with the camera. A different card, even an identical card, will most
likely work perfectly.
►If the Video clip length is set to Max. there will always by a 2-3 second gap between
clips.
►If the clip length would exceed the 4GB boundary on a card formatted to FAT32 (for
example, 4K resolution and Video Quality set to High) the clip will be recorded as a 4GB
clip and there will be 2-3 second gap between the next clip.
►Important: If the firmware detects that the card is too slow (class rating too low), the clip
will be saved and the camera will return to standby mode.

Formatting
Standard formatting tools provided by the operating system are not always reliable and
should not be used. In addition, they do not optimize the SD card's performance.
For optimal card performance it is recommended to either use the Windows setup program
(mSetup, see below) or use the camera's built-in formatter. Instructions for In-Camera
Formatting are outlined below.
In-Camera formatting is also available via the OSD menu.
Another excellent formatting utility is "SD Formatter" which can be downloaded from
https://www.sdcard.org/downloads/formatter_4/index.html. This utility has been specifically
designed to format SD cards.
Breaking the rules tip for 32 GB SD cards: Formattng a 32GB card with exFAT is non-
standard, and not supported by the camera’s integrated formatter nor the recommended
SD Formatter utlity.
However, Windows OS (10 & 11) formattng routne does support this, and limited testng
has shown an exFAT formatted 32GB SD card does work and allows recording long clips
up to the limit of the cards capacity.
In-Camera Formatting
The Camera contains a built-in formatter which should be used to format the SD card.
1. Disconnect the camera and ensure it is turned off.
2. Turn on the camera and wait until it is in one of the Standby modes (steady yellow,
blue or red LED).
3. ►If the camera was set to auto-record, press the Shutter button (top left) to stop
the recording.
4. Press and hold down the Shutter button (top left). DO NOT RELEASE the
button.
5. Rapidly press the Mode button (top right) 4 times.
6. Wait about 2 seconds until the LEDs start to blink.
7. Once the LEDs start to blink, immediately release the Shutter button.
8. ►If the LEDs don't start to blink, release the Shutter button and start over again at
4.
9. The LEDs will blink very quickly while the card is being formatted.
10.The camera will return to Standby mode when the formatting is finished.
USB Connections
The camera requires a USB C (USB Type C) cable for charging or connecting to external
battery packs for continuous recording. A USB C cable is also used to connect the camera
to the PC in order to set the parameters or to access the camera as an external disk. The
camera supports USB2.0.
►Always use HIGH QUALITY USB cables. Cheap cables may lead to all sorts of
problems. If possible, keep the cable as short as possible.
A special USB C cable is required for A/V out (TV-Out, Video-Out) available from the
vendor. The cable has a USB-C plug for the camera and two pigtail leads from that
terminating in two standard "servo-style" plugs.
One is for the analog video out, which in turn needs to have a mating extension cable
terminating in an old style (Yellow) "RCA Phono" plug for connecting to older analog TV
inputs on a compatible monitor.

The TV Out function does NOT have any sound, so only the video (Yellow) connector
needs to be connected to the monitor video input.
The other pigtail (red/black wires) is for external +5V Power IN, which is optional for when
the camera’s internal battery cannot power the camera long enough.
Before you start
Before using the camera for the first time, ensure the internal battery is fully charged. See
below under "Charging".
The Reset button
The reset button is in the small hole located on the right side in line with the center of the
Power Button (looking at the camera from the top with the lens pointing forward). It can be
pressed by carefully inserting a bent paper clip or similar instrument. The Reset button
should only be pressed in case the camera no longer reacts to button presses. Pressing
the Reset button will force the processor to restart. No parameter settings will be lost and
the RTC (Real Time Clock) will not be interrupted.
The Power button
Press the power button (large, round button in the top center) until the LEDs start to blink.
After a short while a steady yellow LED is shown. The camera is now ready for use
(standby).
• To turn off the camera, first stop any recordings that may be running by pressing the
shutter button (top left) and then press the power button for about 2 seconds until
the camera turns off.
The Mode button
The Mode button (top right) enables the camera to be sequentially switched between 3 (4)
different modes, and toggles on the WiFi transmission with a long press (see WiFi section
below for details).
Each button press advances to the next mode indicated by the LED color.
• Video Mode 1 (yellow LED). The frame rate and resolution can be individually
configured.
• Video Mode 2 (blue LED). The frame rate and resolution can be individually
configured.
• Photo Mode (red LED) which also includes Time-Lapse photos.
• Playback Mode (red LED) only when external monitor (Video-Out/TV-Out) special
cable is connected (see USB Connections above for details).
The Shutter button
Press the shutter button (top left) to start or end a video recording or to take a picture.

LED status indicators
The following LED states are for a camera not connected to the PC.
○ Steady Yellow - The camera is in Video Mode 1 and is on standby.
☼Slowly flashing Yellow (1 sec. On, 1 sec. Off) - The camera is in Video Mode 1 and is
recording video. The Video Recording indicator (see configuration) must be ON for this to
work.
○ Steady Blue - The camera is in Video Mode 2 or Playback Mode (if an A/V cable is
connected) and is on standby.
☼Slowly flashing Blue (1 sec. On, 1 sec. Off) - The camera is in Video Mode 2 and is
recording video. The Video Recording indicator (see configuration) must be ON for this to
work.
○ Steady Red - The camera is in Photo Mode.
☼One Red/Yellow flash - The camera has taken a picture.
○ Steady Green - The battery is charging. The green LED works independently from the
other LEDs and is not under firmware control.
The rear LED
If the camera is configured to show the Recording Indicator, then the rear LED will normally
blink in sequence with the main LED while recording or in standby mode.
When the camera is turned on, the rear LED will flash up to three times before becoming
steady. The number of flashes indicate the battery's state of charge. 3 Flashes=Fully
charged, 2 Flashes=charged, 1Flash=The battery is running low and should be charged as
soon as possible.
►The rear LED will blink when WiFi mode is enabled and the camera is waiting for a
smart phone to connect. The top LED will remain on. The rear LED will remain on when a
connection is made. See WiFi for details.
Connecting the camera to the PC
Always connect the camera directly to the PC. Do not use a USB hub. With a card in the
camera, it will always connect as an external device (disk drive, setup), whether the
camera is turned off, turned on in standby, or recording, with just ONE EXCEPTION!
This is when the camera is toggled into WiFi mode, and then the PC USB connection will
just provide external power to the camera.
►You cannot record video or photos if the camera is connected to the PC as an external
drive.
►With no card in the camera, connecting to the PC will toggle the camera into WebCam
mode.

Charging
• Connect one end of the supplied standard USB cable to the camera.
• Connect the other end to a USB, 5V DC power source (wall charger, PC or external
battery).
• When the yellow LED turns on, press the Power button for about two seconds to
turn the camera OFF.
When charging, the green LED will be on. It will turn off when the battery is fully charged.
Charging takes about 2-3 hours with the camera turned off and connected to an external
USB Charger. Batteries are not covered under warranty. If charged with under-rated
chargers or by using a USB hub without an additional power supply, expect longer
charging times. For optimum results, the charging voltage should be +5V under load. Only
use quality chargers capable of supplying 1000mA (1A) and a stable voltage of 5V. Low
quality chargers may not be able to supply enough current and can lead to premature
battery failure or, in the worst case, even destroy the camera.
A new and fully charged battery will record up to 110 minutes of 4K 30fps videos and 155
minutes of 1080p 60fps videos.
►For Dashcam use it is recommended to use a charger or power bank which can supply
at least 2A at a stable 5V.
Automatic Power Off from Standby mode
If the camera is in standby mode you must take a picture(s) or start a video recording
within *30 seconds. The camera will automatically turn off after *30 seconds of no activity.
*This value can be set using any of the setup methods. Automatic Power Off can also
disabled.
When the special A/V cable is connected, automatic power-off will be disabled. This
prevents signal loss during FPV use when the standby time times out.
Recording Video Mode 1 or 2 (yellow or blue LED)
Start video recording.
• Briefly press the shutter button (top left).
• ►If the recording LED has been disabled, the yellow or blue LED will slowly blink 3
times and then turn off, indicating that recording has started.
• ►If the recording LED has been enabled, the yellow or blue LED will slowly flash at
2 second intervals indicating that the camera is recording.
Stop video recording.
• Briefly press the shutter button (top left). The camera will return to the standby mode
from which the video was started.

Taking a Photo (red LED)
• Briefly press the shutter button (top left). The top and rear red LEDs will both be on
when in Photo Mode, and both will flash together when pictures are taken.
• In Normal (single photo) and Burst (multiple fast photos) Modes, both LEDs will
remain on when not blinking. In Time-Lapse and Long Exposure Modes, the
top red LED will turn off between after the shutter trips but the rear LED will remain
on as long as the Mode is still in progress.
Removable Disk Mode
• Make sure the camera is turned off and a memory card is inserted.
• Connect the camera to the PC using a standard USB-C cable. The green LED may
turn on at the same time indicating that the battery is charging.
• ►If this is the first time you are connecting the camera to the PC the operating
system will attempt to install the iCatch drivers. This may take a few minutes.
• The LEDs will blink and after a short while the red LED will turn on.
• The camera is now in Disk Mode and a new removable drive should be available on
your computer. The above procedure may take up to 30 seconds.
• ►You cannot record video or photos if the camera is connected to the PC in
Removable Disk Mode.
USB Webcam Mode
►In Windows 10 and 11 you must ensure that programs have access to the Camera. The
Camera access settings can be found under 'Privacy' from the 'Settings' dialog. Click the
Windows Icon at the bottom left of the screen. Then click the Settings icon (Gear icon) a
little higher up on the left. This will bring up the Settings dialog from which you should click
'Privacy' and then, on the left 'Camera'. Make sure that access to the camera is turned on.
There are two ways in which you can enter webcam mode.
Method 1:
• Remove the SD card and connect the camera to the PC.
• The camera will connect in webcam mode (blue LED).
• ►If this is the first time you are connecting the camera to the PC the operating
system will attempt to install the iCatch drivers. This may take a few minutes.
• If the drivers were installed correctly the camera should now be in USB camera
mode.
Method 2:
• Connect the camera to the PC until it is in Removable Disk Mode. See above.
• Very briefly press the Shutter button (top left). The camera will exit Removable Disk
Mode and switch to webcam mode (blue LED).
• ►If this is the first time you are connecting the camera to the PC the operating
system will attempt to install the iCatch drivers. This may take a few minutes.
• If the drivers were installed correctly the camera should now be in webcam mode.

►Notes: Windows XP has an integrated WebCam viewer. Your Mobius should be visible in
Explorer (My Computer) as a "USB Video Device". This functionality does not exist in
Windows 7.
With Windows 10 and 11, the system "Camera" App (accessed via the Start Menu) is
recommended as the camera’s web cam viewer. It readily connects to the camera and
allows a number of Photo and Video resolutions/frame rates to be viewed and recorded in
high resolution.
OSD (On Screen Display)
Whenever an external analog TV or monitor is connected to the camera using the special
USB-C cable the output will be shown on the monitor. See the USB Connections above for
special cable details.
By using the OSD Menu it is possible to modify the camera's parameters, format the SD
card, view the photos on the SD disk and playback video clips on the SD card.
For more information see "Manual configuration using an external monitor (OSD Menu)"
below.
Camera Setup (configuration and date/time setting)
There are three methods in which the camera's date and time can be set or the
parameters modified: A simple text file (works on most operating systems), using the
camera’s internal OSD Video Out method, and using either of the two dedicated
programs (GUI) for Windows.
IMPORTANT! There are many settngs that conflict with one another or are not
supported by the firmware for all possible resolution/frame rate options. The Manual and
mTool methods do NOT alert the user when a conflicting or unsupported setting is
selected.
When those settings are written into the camera, the FW will either ignore the settng or
replace it with the closest compatible one. This will NOT harm the camera, but you may
not get the results you expect.
The mSetup program method, however, will prevent you from selecting a settng if it’s not
supported by disabling the choice in the program, and it also will alert you to make an
alternate choice in some cases via it’s Tool Tips option (if you haven’t disabled it).
You are strongly advised to use the mSetup method for changing the camera settngs.
The primary conflicts occur between resolution/frame rate, field of view (FOV), lens
distortion correction, (LDC) and electronic image stabilization (EIS).
They are too detailed to be listed here, but you can download a chart that shows all of
these conflicts from this link:
https://static.rcgroups.net/forums/attachments/2/5/5/1/8/a15752627-215-
LDC%20and%20EIS%20SETTINGS%20%26%20RESULTS.jpg.
Whenever the firmware is updated you will need to set the parameters as well as the
date and time. These are reset to their default values whenever the firmware is updated.
In addition, the date and time will need to be set whenever the battery becomes
discharged or is disconnected.

1. GUI (Graphical User Interface) configuration - recommended method for
Windows users
There are two Windows programs available for setting the camera's parameters:
1. mTool, a small utility written by the Mobius team. Different FW versions may require a
different version of mTool.
2. mSetup, a program which supports all the Mobius cameras and all the FW versions.
This is the recommended program to use.
Both programs can be used to modify the camera's configuration or format the SD card.
Both programs communicate directly with the camera and makes configuring the camera
a very simple task.
The camera must be in Webcam mode in order to set the parameters by software. See
Webcam Mode, above.
2. Manual configuration using a text file
The parameters can be also be set by using a text file. This makes it possible to set the
parameters using virtually any computer system.
A "SYNC_PARA.CFG.BAK" text file is automatically created in the card's root folder
each time the camera is turned on.
NOTE: Your Windows PC MUST be configured to show "file type extensions" or you will
NOT see the ".BAK" extension on the config file and will NOT be able to delete it to
properly or rename the edited configuration file on a Windows PC.
If you don’t see the BAK extension, toggle on this ability using the search button on the
toolbar to open your Folder or File Explorer Options pop up window, and click on the
View tab to find and uncheck the box for the "hide extensions for know file types" option.
You may use any ASCII editor, for example Notepad, to modify the parameters. The text
file must be in plain ASCII, it must not be in Unicode. If you don't know what a root folder
is, or you don't know what ASCII is or don't know how to manually edit ASCII files please
use one of the two Windows programs or the method using an external monitor outlined
above.
Only modify the values in brackets [ ] and only enter valid numbers. Once the text file
has been edited and saved, the file must be renamed to SYNC_PARA.CFG (with .BAK
deleted).
Now turn the camera off.
The next time the camera is turned on it will load the new parameters, delete the
"SYNC_PARA.CFG" file, and create a new "SYNC_PARA.CFG.BAK" with the new
settings.

3. Manual configuration using an external monitor (OSD Menu)
It is possible to manually change the configuration settings by using the On Screen
Display (OSD) by connecting the camera to an external analog (NTSC or PAL)
Monitor/TV using the special TV OUT cable (refer to USB Connections section for
details).
3.1 Disconnect the camera from the PC and turn it off.
3.2 Connect the camera to an external analog TV or compatible monitor using the
special cable.
►If the camera is not connected to external power (see above), turn on the camera by
pressing the Power button (large button in the top center) until the LEDs begin to blink.
The camera will start up in Standby Mode.
3.3 Slowly press the Mode button 3 times to cycle from Mode 1 (yellow) to Mode 2 (blue)
to Photo Mode (red) and finally to OSD Menu Mode (red again).
The OSD menu will be shown.
►The two top icons represent the Video files on the card (left icon) and the Photo files
on the card (right icon). When selected, these files can be viewed/played on the monitor.
►The three bottom icons represent the Video settings (left icon), the Photo settings
(center icon) and the General settings (right icon).
►Pressing the Power button will move the focus from one selection to the next
selection. Pressing the Power button on the last selection will return focus to the first
selection.
►Pressing the Shutter button will enter the selection or confirm the selection.
►Press the Mode button to exit the selection or switch to Mode1 when on the OSD
selection menu.
►In-Camera formatting is also available via the OSD menu.
Playback Mode
The TV out analog display will be a low resolution image with a standard (NTSC or PAL)
4:3 aspect ratio. Your video monitor must be capable of displaying a 4:3 aspect ratio
frame size or 16:9 aspect ratio images will look flattened.
If you have a 16:9 aspect ratio monitor that can be set to display the 4:3 image, it will
look normal, but will have black bars above and below your image to fill out the 4:3
frame.
Video playback (Top-left icon on OSD menu).
►When the Video playback icon has the focus, press the Shutter button to enter the
Video playback screen.
A list of all the video clips on the SD card will be shown.
►Press the Power button to move the focus to the next file on the list.
●Pressing the Power button on the last item in the list will return focus to the first
item
►Press the Shutter button to select the video clip to be viewed.
The video clip will begin to play.
►Press the Shutter button to pause or resume playback.
●Fast Forward (FF) or Fast Reverse (FR) is not possible.

View Photos (Top-right icon on OSD menu).
►When the View Photos icon has the focus, press the Shutter button to enter the View
Photos screen.
A list of all the photos on the SD card will be shown.
►Press the Power button to move the focus to the next file on the list.
●Pressing the Power button on the last item in the list will return focus to the first
item
►Press the Shutter button to select the photo to be viewed in full-screen mode.
Firmware Update
New firmware versions usually correct issues found in previous versions but often provide
new functionality which was not previously available.
Use mSetup (click the 'Tools' button) to automatically update the firmware. This is by far
the easiest method.
Manual Firmware Update
DO NOT PRESS ANY BUTTONS during the firmware update process.
There are two similar methods with which you can update the firmware. Always use one
of these methods to update the FW.
Method 1 (recommended method):
• Turn off the camera.
• Connect the camera to the computer and wait until the card is recognized as a
Removable Drive.
• Copy the new firmware file (MAXI4K.BRN) into the camera's flash card root folder.
• Disconnect the camera from the computer and wait until it turns off.
• Wait until all the LEDs are turned off.
• Connect the camera to the PC. The green LED, indicating the battery is charging,
may turn on. WAIT.
• The LEDs will blink indicating the firmware is being updated. WAIT
• The firmware will be updated when the LEDs stop flashing. After a few seconds the
camera will beep once and will be recognized as a Removable Drive.
• The firmware file will have been automatically deleted.
• The date and time and all parameters will be reset to their default values.
Method 2:
• Turn off the camera and remove the card.
• Insert the card into an external card reader and connect the card reader to your
computer.
• Copy the new firmware file (MAXI4K.BRN) into the card's root folder.
• Safely disconnect the card reader from the computer and remove the card.
• Insert the card into the camera. DO NOT turn the camera on or press any buttons.
• Connect the camera to external USB power or connect the camera to the PC. The
green LED, indicating the battery is charging, may turn on. WAIT.
• The LEDs will blink rapidly indicating the firmware is being updated. WAIT
• The firmware will be updated when the LEDs stop flashing. The camera will then
automatically turn on with a beep.
• The firmware file will have been automatically deleted.
• The date and time and all parameters will be reset to their default values.

Recording using an external power supply
With the Mobius Maxi 4K, it is possible to charge the battery and record at the same time
using a standard external USB 5V DC power supply. The power supply may be mains
driven (normal household wall plug), or run off batteries, including the car charger USB
plug (optional accessory) and cable supplied with the camera.
External USB power supplies usually only use the +5V and the - (Ground) wires. The 2
data wires are normally not used. However, some USB power supplies designed for a
specific USB device may use different wiring schemes and thus may not work with this
camera. To avoid possible problems, always use a generic power supply.
For recording video or taking pictures using a standard external power supply connection,
the USB power supply can be connected at any time, i.e. before the camera is turned on,
before the recording is started, or after the recording has been started.
►Only use a quality chargers capable of supplying at least 1000mA (1A) and a stable
voltage of 5V (2A chargers are recommended). Low quality chargers may not be able to
supply enough current and can lead to premature battery failure or, in the worst case, even
destroy the camera.
►Extremely long recordings will cause the camera to become very warm which will affect
the battery life. To avoid early battery failure it is recommended to use an optional Super
capacitor.
Additional heat sink
An additional heat sink is available for when the camera is used for recording video for an
extended time in hot conditions. For example, dash cam use. An additional heat sink can
reduce the internal temperature by up to 10°C.
Additional information
The following functions/parameters need additional explanation:
Beeper
The camera is equipped with a built-in beeper. The beeper volume can be adjusted or
turned off by using one of the setup methods described above.
G-Sensor
The camera is equipped with a built-in Gravity-Sensor which allows the camera to record
upright video or pictures automatically, even when used upside-down. This feature can be
turned on or off by using one of the setup methods described above.
The G-Sensor can also be enabled to sense abrupt changes of the center of gravity
(impact) while recording video. The video file being recorded will be moved to the EVENT
folder on the SD card should a sudden change be detected.
►'Loop Recording' must be enabled if the G-Sensor is also enabled in order to sense
abrupt changes of the center of gravity.
►When the 'Rotate Image' parameter is set to Auto and a recording is started, the video
will be recorded the correct way up according to the position of the camera. Should the
camera be rotated after the recording is started, the new position of the G-Sensor will be
ignored.
►If the camera is permanently mounted in a specific position, for example as a dashcam,
it is recommended to set the 'Rotate Image' parameter to either No or Inverted as
appropriate. You should avoid setting it to Auto.
►Battery power consumption slightly increases when the G-Sensor is explicitly enabled or
partially enabled by setting the 'Rotate Image' parameter to Auto.

(Auto) Rotate Image
The camera can be configured to record upside-down (inverted) which enables the camera
to record normal video and photos with the buttons facing downwards. It is also possible to
set the Rotate Image mode to 'Auto' which ensures the image will always be recorded in
the upright position.
►If Auto mode is selected, the Rotate parameter should also be set to it's normal start-up
mode, either Inverted or not. This will avoid a possible very brief inverted image at the
beginning of the clip caused by the recording starting before the firmware has a chance to
determine in which position the camera is recording.
Loop Recording
Loop recording can be enabled or disabled by software or by using the camera's OSD
menu.
By default, Loop Recording is disabled meaning the camera will record clips until the card
is full. The camera will then stop recording and enter standby mode.
If Loop Recording is enabled, the oldest clips will be overwritten when the card is full. As
such, the camera will never stop recording and only the most recent clips will be available
on the card.
►Loop recording is only permitted for 1 min., 3 min., and 5 min. clip lengths.
Motion Detection
Motion Detection only works in video modes. It does not function in Photo Mode.
When Motion Detection is enabled, the Power-Off Standby timeout setting will be ignored.
The camera will, therefore, not turn off unless there is no power left to keep the camera
running, the memory card is full or the camera is manually turned off.
When Motion is detected, the camera will start recording and the selected Motion Timeout
counter will be started. If no further motion is detected by the time the counter runs out the
camera will save the recording and return to standby mode where it will wait for new motion
detection.
If motion is detected while recording the timeout counter will be reset to the selected
timeout.
The camera will continue recording until no more motion is detected and the timeout
counter runs out or the video clip length is reached, or the memory card is full.
Lens Distortion Correction (LDC)
LDC has a conflict with the EIS function, and will not function if EIS is turned on at the
same time.
When EIS is Off, turning on LDC can reduce (but not fully eliminate) the amount of fish eye
distortion in all camera resolution/frame rate settings that the camera supports. With
mSetup, unsupported resolution/frame rates will be ghosted out. With the other manual
setting tools, users can refer to the table of interactions linked above under "Camera
Setup".

Image Stabilizer (EIS - Electronic Image Stabilization)
Image Stabilization can help reduce jerky camera motion in recorded video for the
resolutions / frame rates supported. It will also disable the LDC function when enabled.
The Time Stamp should be turned off when Image Stabilization is enabled, otherwise the
stamp will move around and not be fixed when the video is played.
►Image Stabilization is only supported for Wide FOV for 4K 30fps, 2.7K 30fps, 1440p
30fps, 1080p 30fps and 1080p 60fps. Also these videos will (ironically) have essentially no
fisheye distortion (with LDC settng On or Off), and the images will be downscaled to a
much narrower FOV.
►Image Stabilization with 4K resolution may not yield the desired results.
WiFi
There is no specific WiFi app for this camera, but the iCatch App from the chip
manufacturer may be used to preview videos and download video / photo files to your
phone.
It can also be used to start a video recording or take a photo with live-view.
No camera settings can be modified using the WiFi app.
The WiFi App "iSmart DV2" can be downloaded and installed from Google Play or the
Apple App Store.
WiFi for the Mobius Maxi 4K can be set up as follows:
• Press the Power button to turn the camera on. The camera will enter standby mode.
• Press and hold the Mode button for approx. 3 seconds until you hear 2 beeps. The
red rear LED will start flashing continuously, along with a beeping sound. WiFi is
enabled, waiting for a connecting.
• In the WiFi settings of your phone, select "Maxi4K" as the new WiFi connection. On
Android phones, the WiFi settings can often be found under Settings->Connections-
>Wi-Fi.
• Once connected, the rear LED will stop blinking and remain steady.
• Launch the "iSmart DV2" which you should have previously downloaded and
installed from Google Play or the Apple App Store.
• Tap the MAXI4K camera to connect to the camera. You may first have to "Add New
Camera".
• The main menu with live-view will be shown. From here you can
view/download/delete individual or all photos or video clips. You can also start and
stop a video recording.
• You should NOT attempt to change the settings by tapping the gear icon. This is a
generic app and the settings do not correspond to the Mobius Maxi 4K settings.

Trouble shooting
Q. When I press the Power button, nothing happens (the green LED may blink briefly).
A. An apparent 'dead' camera can be caused by the following:
• The battery is flat or defective. Replace or charge the battery.
• The Firmware may have locked up. Use a paper clip or similar object to press the
Reset button.
• The lens module cable is not properly inserted or defective. Ensure the lens cable is
firmly and squarely seated at both ends. Take note that the connectors have an
opening mechanism. Never use force to insert/remove the cable.
Q. When I turn on the camera or while recording the rear LED continuously blinks very

power is connected and the 'Auto Record External Power' parameter is set appropriately.
A. External USB power exceeds ~5.25V or is under-powered.
Q. Playback is erratic or stutters or the playback colors are psychedelic or the video
flashes, has corrupted blocks etc.
A. Always first copy the video file from the memory card to your hard drive.
• Your PC or graphics card may not be powerful enough to playback the video
stream.
• You may not have enough memory installed in your PC.
• Use VLC Media Player or MPC-HC (Media Player Classic - Home Cinema).
Windows Media Player often chokes on underpowered machines.
