2 INSTALLATION

2.1 VIDEO CONNECTIONS

Camera and CCTV monitor must use 75 Ohm video cable (e.g. RG-59, RG-6, RG-11) with BNC connectors.

Due to inappropriate absorbability, 50 Ohm coax cable (e.g. RG-58), antenna cable and other types of coaxial cable are not compatible.

All connected video sources must provide a 1 Vpp NTSC or PAL standard video signal.

When converting transmission lines (twisted pair, fibre optics, radio) to the video inputs, be sure to verify accurate receiver calibration.

ATTENTION: In order for the system to auto-detect the appropriate video format (NTSC or PAL), make sure that there is a video signal on video input 1 upon power-up.

2.2 AUDIO CONNECTION INSTALLATION

The ECOR DVR provides 1 audio input and 1 audio output.

The input is designed for max. 500 mV to 10 KOhm line audio signals.

ATTENTION: The direct connection of a non-amplified microphone is not supported (a microphone amplifier is required).

The installation must be done with audio coax cable and RCA plugs.

The output provides a max. 500 mV to 10 KOhm line audio signal and may be connected to a monitor‘s audio input. The direct connection of passive speakers is not supported.

AUDIO RECORDING FUNCTIONALITY:

Audio recording is activated / deactivated in the RECORD menu.

Audio channel is always recorded together with video and is independent of the image recording rate. There is no specific camera allocation.
