Connecting Analog Cameras to the Encoder
Connect analog video cameras to the encoder using the coax/BNC connector video inputs
on the front of the encoder. The encoder supports 4 video inputs and is initially configured
for a composite video input with 75 ohm termination. The video standard (NTSC/PAL) is
automatically detected. The video input status LEDs will turn on if the encoder locks to the
video signal. If the video source is connected in parallel with other equipment, the input
termination should be turned off, this can be done through the Avigilon Control Center
software. Connections made using 75 ohm coaxial cable have a recommended maximum
length of 750 feet (229 meters).
Connecting the Encoder to a Network Video Recorder (NVR)
Important:
To avoid networking problems, use only network switches recommended by
Avigilon.
Connect the encoder to the same network as the NVR running the Avigilon Control Center
software. The encoder will automatically obtain an IP address and will be detected by the
software. For more information on how to configure the encoder consult the software user
guide. The Connection Status LED on the back of the encoder indicates the encoder’s
progress in connecting to the NVR as described in the table below.
