5.0 User guideline
5.1 Start the Machine
Before starting the machine, please make sure all the items in the “Security Notice” at the beginning of this
manual are fulfilled.
Before starting the machine, please check the system connection, input and output equipment connection,
and power connection.
Please insure the video-recorder’s input video (PAL) and the monitor (PAL) meet the demands.
Start exterior equipment after checking over.
Insert the removable hard disk case to the end, and lock it up (turn right the hard disk lock); Push the power
button, the machine start to work.
If the machine stops abnormally while recording last time, then after restarting, the machine will restore the
record, hard disk can automatically clear up, then resumes to the status before power-off (including time and
alarm status), and continue the interrupted recording. The time for hard disk resetting and clearing-up
depends on the recorded information on the hard disk, which varies from ten seconds to a few minutes. So
please wait patiently.
5.2 Turn off the Machine
Normally turn off the machine when the system shutdown, which means do not to turn off the machine while
playing or system setting up, especially not to turn off the machine while recording (otherwise the system will
start automatic recovery function when turn on next time).
Push recording button to stop recording or push playing button to stop playing or exit from system setup
menu, then turn off the power.
It is best to turn off the video-recorder power first, and then turn off the power of external equipments.
If do not use the video recorder for a long time, should pull out the power line from the electrical outlet.
5.3 Ordinary Recording
Connect the power to all related equipments; ensure that there is video input.
Push display button to check spare space of the hard disk, if there is no much space, please think whether
to change hard disk first or select overwriting modes.
Check recording parameter setup before recording; select video quality, frame rate. Or push quality button
to select image quality, you cannot change record setting during the process of recording.
Manual recordings belong to ordinal recording. Under the manual mode (non-watch-on status), you can
choose certain channel image surveillance; here pushing record button will record all channels’ image video.
 Push the record button to begin recording, four channels will start simultaneously recording.
During the process of recording, if the hard disk is full, and the system is set to automatic overwrite, then
the recording will not be interrupted, and it begins to overwrite from the earliest recorded area; if the system is
set to overwrite disable, it will stop recording when hard disk is full, the bottom right corner of the screen
displays “*” which shows disk overwriting.
If the hard disk is used over 90% when you push the record button to record, the machine will inform you
by blinking massage. When over 99% of the hard disk while recording, the char [M] which instand master hard
disk or [S] which instand slave hard disk will blink.
5.4 Alarm Recording
Alarm recording is not started by manually pushing record button, all the recording started by manually
pushing the record button are ordinary record.
Alarm recording can be activated by alarm input signal, so it is a must to check whether the connection of
alarm input equipment is correct, stable and reliable before turnning on the machine.
The prerequisite condition of whether the alarm recording can be activated by exterior input signal or the
changes of exterior environment is that the system must beset on guard and that period is set to “S” or "P"
in record schedule setup, also, that channel must not be set to “NOT-INSTALLED” insensor setup.

AV6570/H02 17
Under the state of off-guard, system will never start alarm recording. Setting guard on or off is achieved
through pushing the alarm button on the front panel, but not through system setup menu and window. Under
watch-on situation, the character “ALARMED” will display on the screen.
Alarm video recording can not stop by pushing record or stop button, but can stop by removing guard.
Because once the system is set on guard, the guard cannot be removed randomly, so there is a password
protection to remove guard, only after inputting correct password, you can take guard off.
 Check alarm recording setup before recording, confirm the video quality and the frame rate, the record
setting cannot change during recording process.
 In the process of alarm recording, any buttons do not work except alarm, schedule, display and channel
select buttons.
As long as the alarm input signal is effective, the alarm recording continues. When the alarm input signal
loses efficacy, the time set up by "SENSOR RECORD TIME" becomes effettive, and when the time goes out,
the alarm recording automatically stops. In course of this, if you want to manually stop alarm recording, the
only way is to remove guard (answer the password).
While the hard disk is full, it automatically overwrites the hard disk.
5.5 Time Recording
 Time recording starts and stops recording automatically according to the pre-arranged time period. It is
applied to fixed timetable, for example, the periodical work time recording (or off time recording) with fixed
start/stop time.
Once timing recording function is set, it will work simultaneously on four channels, that is to say, four
channels recording can only use the same timing setting, simultaneously starting and simultaneously
stopping.
To start Time recording function, besides making record schedule setup beforehand, must push down the
schedule button on the front panel. While pushing down this button, the time recording symbol "SCHEDULED"
will display on the screen. Without pushing the schedule button, the Time recording parameter setup will not
work.
In the process of time recording, no buttons work except alarm, schedule, display and channel select
button. In time record state, you can repush schedule button then enter password to stop time recording.
Because Time recording is correlated closely with time, so before using this function, should previously
adjust the time.
While the hard disk is full, it automatically overwrite the hard disk.
5.6 Playback
In the stop state, push play button will always play the images recorded most recently.
In the process of playing, push pause button to pause playing, re-pushing play button can resume
continuous play.
In the process of fast forward playing or fast backward playing, pushing pause button then push play button
will begin normal playing from the current place.
Continuous pushing forward button will change the fast-forward among three levels of speed(X2 X3, X4)
circularly.
Repush play button or push stop button will stop playing.
5.7 Search Play
In the stop state, pushing search button. Time search window will display on the screen:
-HARD DRIVE: current working hard drive.
- the start time and the end time of the record segment which the cursor point to.
- NO: the ID of each record segment.
- TYPE: the record type, which includes three types: normal, sensor, time.
- TIME: the record start time.
Push upward or downward button to move cursor, leftward or rightward button to see next or previous page,
then push enter button to play the record which the cursor points to.

This DVR can control all speed domes which are connected to the DVR.
To control the speed dome, make sure all the lines are correctly connected, first you must set the right
protocol, baud rate, and speeddome’s address, please refer to protocol set.
For example, you connect the first speeddome to channel one, you have to make sure that the baud rate,
the protocol, and speeddome1’s address is the same as the speeddome you connect to the channel.
Nowyou can control the speeddome, push the PTZbutton:if the character “PTZCAM 1” will appear on the
screen, that means you are now controlling the speed dome connected to channel one. Push the button again
to control the speeddome that connect to the channel two, the character “PTZ CAM 2” will appear on the
screen, the same to channel three, channel four. Then push the PTZ button one more time to exit from PTZ
control.
During the PTZ control state, you can push upward, downward, leftward, rightward button to move the
speed dome, and push the enter button to stop. If you push the Iris button, the character “Iris” will appear on
