Hello,
I'm designing a cctv-security system which has to be integrated with a doorphone-system. Let me explain the purpose:
Outside:
1 Video-doorphone with standard camera
5 standard security camera's
all composite.
Inside:
3 lcd-inwall-monitors of 12 or 15", non-touch
next to it a doorphone intercom without videoscreen. This intercom has multiple free programmable buttons (rs232 of contact).
When the doorbell rings (alarm-contact), the monitors display the main camera with the others at the side of te screen.
When the user presses button 1 eg, camera1 is viewed in full screen
When button 2 is pressed, the next camera is viewed in full screen
Button 3 gives a quad-view
...
So, I'm looking for something that does the switching/multiplexing with simple rs232 commands.
As a recording device, everything is possible (geovision, dedicated micros, ...) or a combination of a recorder with the above multiplexer.
Can someone help me to find such a device ?
Thanks in advance,
A european it-er
