Motion Detection Security

during the past month, houses eighteen our neighborhood were broken in when the owners were absent. they have no idea who this is done, we are about to go to New York for two weeks, and we really need a security camera (or more) to save while we're gone .
Cost does not matter as long as he is not crazy, but something that has motion detection and records when it detects motion?

Today this is not the security camera that has a motion sensor, but the DVR. Basically, you run your security camera and set your DVR automatically records when he noticed the change pixel. You can then set a time limit after the change pixel has ceased for the DVR to stop recording. So, let's say someone enters your home. The DVR will begin recording the stream. Then, the left two minutes later. You set your stop at 30 sec. Thus, 30 sec. after the departure of the person and the pixel changes have stopped, DVR stop recording.

The cameras usually do not detect movement, but you have to buy a camera multiplexing controller, they are supplied with a disk drive to record and can be configured to detect motion.
