chorlton2080 0 Posted May 8, 2016 Hi folks Firstly, I realise that my attempts to get motion detection to work for outside cameras is going to be difficult: but surely not as difficult as I've been experiencing. I have a Swann DVR4-4600 720p camera system. The cameras are pointing towards the front and the side of the house. Both display reasonably clearly. However, despite setting the motion detect trigger area onto a front door and brickwork, the trigger activates far too frequently. So, time to tune with the sensitivity. Unfortunately, even with a sensitivity of "50", the scale is 1-50 (highest to lowest sensitivity respectively), the motion trigger occurs with nothing obvious detectable from the image. Surely an elephant must pass in front of the scene under a sensitivity of 50 for it to activate? Swann are helpful: they think motion detection outside should be realiably. They have even provided me with an experimental Version 16 of the software to try out, which doesn't help. Prior to my Swann unit, I was using a Raspberry Pi with a home-made Python routine to do motion detection on the same scene: this worked incredibly reliably. Swann think I should replace the DVR box: this sounds absurb given the box is clearly capable of running the software supplied, if anything it is the software not a hardware issue. If anyone can help I would be very appreciative. Thanks Share this post Link to post Share on other sites
Daryl733 0 Posted May 8, 2016 Video Motion Detection are never that precised. Lighting changes, moving trees, etc will trigger the video motion detection. Check if your system support more advance analytic such as line crossing. Share this post Link to post Share on other sites
