2. INSTALLATION

ATTENTION: The installation should be effected by qualified personnel only. Connect power source only after having finished the further installation.

2.1 Delivery scope

Check the delivery scope (see 4.) before starting the installation.

2.2 Video connection installation, DVR cascading

Sample installation with maximum camera and monitor configuration:

Cameras and monitors have to be cabled with 75 Ohm video cable, e.g. RG-59, RG-12 and suitable BNC plugs.

Due to inappropriate absorbability, 50 Ohm coax cable (e.g. RG58), antenna cable and further types of coax cable are not suitable.

All connected video sources must provide a 1 Vpp PAL/CCIR standard video signal.

When interconnecting transmission lines (twisted pair, fibre optics, radio) to the video inputs, ensure the accurate receiver calibration.

The MAIN monitor may optionally be connected through a Y-C (S-Video) cable to achieve an improved image quality.

For local DVR operation, MAIN monitor connection is compulsory. Call and matrix monitors can be connected optionally.

ATTENTION: Make sure that there‘s a video signal on video input 1 upon start-up, as this input is required for video system auto detection (PAL/NTSC)!
