Monitoring Sensor

[Ameen]

Hi, I new in this forum,
Can anybody suggest to me the best sensor to monitor crowd?
I need to do a small project to monitor crowd by using camera. This camera will be trigger by any sensor and send the picture as an MMS to the recipient. The camera also already configured to be manually take picture when i send specific command from mobile phone.
I already try using the Motion detection sensor but not very efficient to be used. I need something that can trigger the Camera in more effective way.

Thank you

Have a look at iSpy. It interfaces to video cameras and can take video clips when there is movement in certain parts of the frame.

Not sure if it can take still shots, but download it and find out.
