2-6.2 Audio signal input
2-6.1 Audio signal output
The video output is divided into PAL/NTSC VGA output & HDMI output (selective
configuration). When you replace the monitor by the computer display, there are some issues to
notice.
TV is not a credible replacement as a video output. It demands reducing the use time and
control the power supply and the interference introduced by the nearby equipments strictly. The
usage of low quality TV can lead to the damage of other equipments.
Audio port is BNC connection.
The input impedance is high so the tone arm must be active.
The audio signal line should be firm and away from the electromagnetic Interference and connected
credible which avoid false and joint welding and oxidation. The high voltage current should be
avoided especially.
Commonly the output parameter of NVR audio signal is greater than 200mv 1KΩ (BNC) which
can connect the low impedance earphone and active sound box or other audio output equipments

phenomena.
3 Basic operation
3-1 Turn on
Plug the adapter and turn ON the power supply switch. Power supply indicator light indicates
turning on the video recorder. After the startup you will hear a beep. The default setting of video
output is multiple-window output mode. If the startup time is within the video setting time, the
timing video recording function will start up automatically. Then the video indicator light of
corresponding channel is ON and the NVR is working normally.
Note: 1. Make sure that the input voltage corresponds with the switch of the NVR power supply.
2. Power supply demands: 220V±10% /50Hz.
We suggest using the UPS to protect the power supply under allowable conditions.
3-2 Turn off
There are two methods to turn off the NVR. Entering [main menu] and choosing [turn off] in the
[Turn off the system] option is called soft switch. Unplug the power adapter to turn off the NVR.
Pressing the power supply switch is called hard switch.
Illumination:
1. Auto resume after power failure
If the NVR is shut down abnormally, it can automatically backup video and resume previous

working status after power failure.
2. Replace the hard disk
Before replacing the hard disk, unplug the power adapter to turn off the NVR.
3. Replace the battery
Before replacing the battery, the setting information must be saved. The NVR uses button battery.
The system time must be checked regularly. If the time is not correct you must replace the battery,
we recommend replacing the battery every year using the same battery type.
Note: The setting information must be saved before replacing the battery otherwise information
will be lost.

1. Hard disk capability
2. Overall capability option
Appendix 1. Hard disk capability calculation
Make sure the hard disk is installed to the NVR for the first time.
There is no limit for recording machine. We recommend 120G~ 250G sizes to keep better stability.
The hard disk capability formula is:
Overall capability（M）= Channel number*time（hour）* Capability in an hour（M/hour）
The recording time formula is:
Recording time（hour）= Overall capability（M）Capability in an hour（M/hour）*Channel number
The NVR introduces the H.264 compression technology. Its dynamic range is very large so the hard
disk capability calculation is based on the estimation values of each channel creating files in an
hour.
