Quick Start
Step 1. Please check that all connections are correct before powering on the camera.

Page 3of 56
Rev 1.6 7/19
Step 2. Set the system select switch for your desired video output resolution and frame rate.
For many applications, setting 0 (1080p-60) will provide the best overall performance.
For highest possible resolution, use setting 0 (1080p-60) or 6 (1080p-30), however your actual realized frame rate may
be limited to a lower value than 60 fps by your software and/or network connection.
NOTE: After changing this dial, you need to restart the camera to see the effect. Turn the camera off.

Step 3. Press the Switch ON button on the rear of the camera, the power lamp will illuminate.
Step 4. The Pan-Tilt mechanism will rotate the lens to the maximum position of top right after the camera starts, then it will
return to the “center”. The process of initialization is now complete. (Note: If the position preset 0 has been stored, the position
preset 0 will be called up after initialization in lieu of “center”)
Step 5. (Optional) If you want to restore the factory default settings, press [MENU] button to display the OSD menu. Select
the item [MENU] -> [RESTORE DEFAULT] -> [Restore]. Set the value [Yes], press [HOME] button to restore the factory
default settings.

controller to perform panning, tilting, zooming and
focusing, as well as store and call back preset positions.
Button Instructions：
1. In these instructions, ‘press the button’ means to
press and release. A special note will be given if holding a
button down for more than one second is required.
2. When a button-combination is required, do it in
sequence (not simultaneously). For example, ‘[*] + [#] +
[F1]’means press [*] first and then press [#] and then
press [F1].
1. Pan/Tilt Control
Tilt up: Press [ ]
Tilt down: Press [ ]
Pan left: Press [ ]
Pan right: Press [ ]
Face the camera back to front: Press [HOME]
Press and hold the up/down/left/right buttons, to keep
panning or tilting from slow to fast, (until the camera
reaches the mechanical limit). The camera stops as soon
as the button is released.
2. Zoom Control
Zoom Out: press [+] button under FAST or SLOW
Zoom In: press [-] button under FAST or SLOW
Press and hold the button, to keep zooming in or out
(until the lens reaches the mechanical limit). The lens
stops as soon as the button is released.
3. Focus Control

standby mode the camera will provide no image, respond
to no commands and use less than half its normal power.
Press [ ] button again to put camera in normal mode.
6. Presets - Setting and Clearing
1. To store a preset position: The user should manually
setup the desired shot using the Pan Tilt and Zoom
controls. Press the [PRESET] button first and then press
the numeric button [0-9] to which you want to assign the
shot. Ten total preset positions (0-9) are available from
the IR remote control (255 available via RS232/RS485/IP
Interfaces).
2. To erase the memory content of a preset position: The
user should press the [RESET] button first and then press
the numeric button 0-9 associated with that preset.
Note:
Pressing [*] + [#] + [RESET] in sequence will erase
all presets in the memory.

Page 12 of 56
Rev 1.6 7/19
7. Recalling Presets
Pressing any of the numeric buttons [0-9] directly will
recall a stored preset position and settings.
Note:
No action will be executed if a specific numeric preset
position has not yet been saved.
Note:
Presets assigned via the IP interface do not correlate to
presets set via the IR remote control.
8. Camera Selection
Press the [1-4] button corresponding to the camera with
the IR address that you want to operate. This allows for
up to 4 cameras to be operated via the same IR remote in
the same room.
9. Camera IRAddress Set
Press 3 buttons in the sequence shown below to
set/change the camera’s IR address. This allows up to 4
cameras to be controlled from the same IR remote control.
Be sure that only one camera is picking up the IR signal
when you perform this function. If multiple cameras
receive the command, they will all change to the new
address.
Address 1: [*] + [＃] + [F1]
Address 2: [*] + [＃] + [F2]
Address 3: [*] + [＃] + [F3]
Address 4: [*] + [＃] + [F4]
10. Image Freeze
Press the [ ] button to freeze or unfreeze the video
image. This can be useful while recalling presets to hide
camera motion from your viewers.

Serial Communication Control
In default working mode, the camera is able to connect to a VISCA controller with an RS232C serial interface.
➢RS232 Communication Control
The camera can be controlled via RS232. The parameters of RS232C are as follows:
Baud rate: 2400, 4800 or 9600 bps.
Start bit: 1 bit.
Data bit: 8 bits.
Stop bit: 1 bit.
Parity bit: none.
➢RS485 Communication Control
The camera can be controlled via RS485, Half-duplex mode, with support for VISCA, Pelco-D or Pelco-P protocol.
The parameters of RS485 are as follows:
Baud rate: 2400, 4800 or 9600 bps.
Start bit: 1 bit.
Data bit: 8 bits.
Stop bit: 1 bit.
Parity bit: none.
When powered on, Pan and Tilt will rotate to the maximum position of top right after the camera powered up. Then it will
return to the “center”. The process of initialization is now complete. (Note: If the position preset 0 has been stored, the
position preset 0 will be called up after initialization, in lieu of “center”).After initialization is complete, then the user can
control the camera with commands in the command list.
