Activate monitor display through intercom button

[fareall 0]

Hi there CCTV pros!

 

I am looking at the following setup in a small office:

8 - cameras

7 - monitors

1- Hybrid DVR

 

I would like to know if and how the following can be done with the least amount of extra equipment, if possible.

 

2 of my monitors are large screen LCD TVs that will have the feed from sat tv in one input and the CCTV feed in another input (probably composite or maybe HDMI).

 

When a visitor presses the intercom button I would like the display to show the camera either in the TVs PIP or flash to that input source.

 

Since this involves the intercoms the dvr and the tvs I was hoping someone bumped into this during their installs.

 

(The intercom I was hoping to use is SIP based and will be connected to the company's SIP based IP PBX phone system - http://www.telephonydepot.com/Catalog/CyberData/CyberData-VoIP-Intercom.)

 

Thanks!!
