DVR with Trigger to hold image

[scracha 0]

Hello.

 

Looking for a 4 channel DVR or PC based solution that can be triggered externally to take a (jpeg?) snapshot from the 4 cameras. The snapshot would be saved with a timestamp. The snapshot would then be displayed on the screen until the next trigger event.

 

Ideally it would have an easy to use dial, buttons, touchscreen or simply a left and right mouse button to view the last few snapshot(s), whilst still recording snapshots if the external trigger event happens.

 

Any assistance with what to purchase would be appreciated.

 

Thanks

Most systems can do a motion based capture which can be dialed in to a set time, say 1-2 seconds of record when motion is captures, I don't know about saving the image to screen, not exactly how a CCTV system works.
