CONNECTING VIDEO INPUTS
The SP04-140 offers two analog video inputs. The unit automatically detects the video standard (PAL or NTSC) and accepts both color and
black-and-white analog video at both inputs.
The Video In (2) connector also supports PTZ operation using the following protocols:
•
Coaxitron:
When the SP04-140 receives a camera control command, it transmits that command up the coaxial cable to the PTZ device.
Since Coaxitron is a single-direction protocol, the PTZ device cannot return any data to the unit. By default, Coaxitron is disabled.
•
Pelco D (RS-422):
When the SP04-140 receives a camera control command, it transmits that command via the serial wires to the PTZ
device. Pelco D is a bidirectional protocol.
