2.2.2 About DVD/CD burner
When fitting a DVD/CD burner in this DVR ensure that it is a serial device and not parallel.
Ask for DVD200. It is also recommended that the first serial drive port connects to a SATA
HDD and the second port connects to the DVD/CD writer. Subsequent HDDs can be fitted to
port 3 onwards.
2.2.3 Connection of exterior mains power supply
Ensure that the machine supplied is suitable for the mains voltage supply.
2.2.4 Install DVR in the machine cabinet
The size of DVR is 2Ustandard industrial case,441mm (Wide)x430mm (Deep)x89mm (High)
Put the cabinet in a ventilated place. Avoid extreme heat, humid and heave dusty conditions.
After long time use, you should clean inlet opening, cooling fan etc. with a soft dry brush.
2.3 Connection of video/audio input/output
2.3.1 Connection of video input
The video input interface is BNC. The request of video input is PAL/NTSC

75ohms. The video signal should comply with national standards. High SNR, low distortion,
low interference, natural colour and suitable brightness are also needed for the video signal.
Guarantee the stability and reliability of the camera signal:
The camera should be installed in a suitable place. Where backlighting issues or low
illumination surroundings are encountered the user should use backlighting compensation or
low illumination features on the camera.
The power supply of the camera should have the same grounding with the power supply of the
DVR to ensure the normal
operation of the camera.
Guarantee stability and reliability of the transmission line
Use high quality, good shielded BNC and choose suitable BNC model according to the
transmission distance. For long distance you should use twisted pair cable with baluns or use
optical fibre transmission to ensure video quality. You should keep the video signal away from
strong electromagnetic interference, especially from high voltage power lines.
Ensure connections are well made and kept clean
The video line and shielded wire should be firmly connected and kept dry and clean.
2.3.2 Audio input
HD1 4/8-ch use BNC. 16-ch uses RCA audio cable via a 25-pin connector. Due to high
impedance of audio input, you must use live sound input.
Audio transmission is similar to video transmission. Avoid interference, keep clean and dry and
do not locate near power lines.
2.3.3 How to choose and connect video output device
Video output includes a BNC(PAL/NTSC BNC(1.0VP- P, 75O))output and a VGA output.
We recommend you use a heavy duty standard metal case CCTV monitor as video output
device for best results. This monitor has the following advantages:
1. Will adapt to industry standards for a longer time, will resist heavy wear and tear and is less
likely to break down.
