Hi,

I'm fairly new to the world of PTZ camera control so apologies in advance if I've overlooked something obvious.

I was under the impression that PTZ cameras required 3 connections:

A power supply
A co-ax connection
A RS485 connection

There is a Sony PTZ camera already installed at my place of work which is fully functional. However it does not have a RS485 connection? It has a 24v AC power connection along with a Co-ax connection. How is this camera able to move? (The Co-ax cable is run straight from the DVR to the camera). It would appear the telemetry of the camera is somehow controlled via the co-ax cable? Is this the case?

Cheers

George

Dunno about Sony, but HikVision has, as part of their HD-TVI implementation, incorporated PTZ over coax functionality.
Bascially, any HikVision HD DVR will be able to control a HikVision HD PTZ via coax.

Way cool, yes?
