4.2.5 Connecting a Camera to the Unit
The unit accepts composite video (1Vp-p) from PTZ cameras or stationary analog cameras
(standard, thermal, IR, and so on). Video connections should use a 75Ω coax cable. See the
Appendix for restrictions on the length of the video cable.
Connect the first camera to Channel 1. The PAL or NTSC TV standard is automatically detected by
connecting a camera to Channel 1. All channels must use the same TV standard.

4.2.6 Connecting Audio Inputs for Recording on a VMS
You can connect a microphone to each of the encoder’s four channels and record audio
synchronized with the video in the Video Management System (VMS).
