I’m looking for a security camera system that can leave running and following an event (ideally a 24VDC digital input from an alarm device) the system record the last few minuted of surveillance footage. This way I just get snippets of video footage leading up to an event, instead of having hours of footage to review. Is there such a thing available?
The above question was asked by one of our customers. This is the information the CCTV Camera Pros sales team provided.
Thank You for contacting CCTV Camera Pros. You can use an IP camera or a surveillance DVR with digital IO or alarm inputs to trigger an event based on a low voltage input from an external device. Please take a look at this article that I wrote recently:
The only challenge that I see with your requirements is the ability to record the previous few minutes. While IP cameras and surveillance DVRs can record upon alarm input, they typically can only buffer and go back a set number of seconds (a minute at the most) to record prior to the event.
As an alternative, you can have the camera or DVR set to record continuously, but also have alarm events “bookmarked” and notify you. This way you can go right back to the alarm event and rewind the video more than 10-15 seconds (which is what you would get if you were recording only on motion event instead of continuously).
The IP camera or DVR can be setup to overwrite mode which means that that disk drive used for video storage automatically gets recycled when it is full (overwriting the oldest video first).
Please take a look at these IP cameras if you are looking for a stand alone camera solution and only need a few days of recording at most.
If you are looking for a multi-camera solution and/or want to record more than a day or two of video, I highly recommend our Viewtron CCTV DVR product line with HD cameras:

Please let me know if I can help further.
