Hello everyone, I just joined this Forum because although I have had my Hikvision CCTV system on the farm for about 2 years now I have what I would have thought was a simple question. I have asked my supplier but they do not respond. My set up is a Hikvision NVR with a 3TB drive, 2 Hikvision 4mm dome cameras and a Hikvision PTZ camera. A cracking setup which does it's job well.

My question is about motion detection. I know that you draw the areas on the screen where you want the system to trigger a warning when anything moves in that area but is it possible to draw an area on a screen when reviewing previous footage ? I will try and explain myself a little better. Suppose I go back say one week and am looking at a recording of my farm yard. Is it possible to draw a shape/area on the screen that will stop the rolling video when something enters that area ? At the moment, when I want to look for something, I am just rolling through the footage at 16x speed and stopping it whenever I see something that I think I should investigate further. I know that at 16x it only takes approximately 4 minutes to look at an hour’s video but I just wondered if a motion detect area could be programmed retrospectively as it were.

Thanks to anyone who can help me with this question.
 
Interesting challenge. For someone who writes code for running in the NVR , maybe possible. What comes to mind, add a camera with motion detection to “ watch” your screen and capture changes. Then review its motion capture. If the screen has time -date info, you have a reference.
Brute force approach. Gives you flexibility of area to watch in multi pass review and would work unattended, partially. Still have to review “captured” images.

Thank you Master Tinkerer. At least that tells me that it isn't possible at the moment. But I ask you please to consider this as an example of why this could be useful : I have a farm. My cameras point to various places and inevitably of course they capture field views. In the U.K. at the moment we are suffering terribly with sheep rustling, and that includes butchering them in the fields. I also have people (and animals - foxes, dogs etc) that sometimes appear in the yard and I would like to know the origin of their entry. We have experienced delivery drivers who say they tried to deliver something but "no one was available to take delivery" There are all sorts of instances when it would be really useful to be able to draw a detection area in previous video footage so that we wouldn't have to wade through hours of video while glued to the screen.

I admit to not being very conversant with the whole motion detection system and I probably need to get up to speed on that. And I like your idea of the motion detection camera (which I have) being used to watch the video. I'll give it a try. Thanks again.
