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.
