I bought 8 Hikvision cameras for my place w/o thinking about it too hard. I have a security issue and wanted to record who might be snooping around my house. I also got the 7208 DVR (I think it's called) and after much swearing and configuring, got all 8 cameras working at the same time. Then I tried to turn on motion detection. Who wants to sift through 24 hours of footage each time? here is really what I want to accomplish: 1. Record all the cameras, all the time, to looping recording footage. Set a file limit size, and it will over-write whatever is oldest. 2. ALSO have motion detection turned on. When motion is detected, save off a sub-clip of the always-recording files to a NEW "motion" file, or at the very least, save off the time/date/range of the motion detection as a text or binary file with reference to the always-being-recorded file. 3. I think Hikvision's motion detection STINKS by the way. shadows from things waving in the wind, and even a bee, will set off motion detection on my cameras, no matter what sensitivity I have them set at. 4. Record all the files to the hikvision DVR, but be able to access those files from elsewhere on my network, so I can have a *powerful* server analyze the footage of the supposed motion detection points and cull out the ones that are false, and send me mini videos of the ones that are actual intrusions. I want to be able to access the recorded video from my network computer. 5. I have all my cameras set up on schedules. but sometimes I want to stay up later than normal by a few hours, or go to bed earlier than normal. I want to be able to select from certain groups of cameras and tell them to "arm earlier than normal" or "arm later than normal" by a delta amount. This is totally not possible in hikvision's stuff. 6. likewise, I want to be able to leave the house for a while on a weekend and tell it to "arm until I turn you off", not on a schedule. This should be dead simple and be only a few clicks. I don't know what my ability is to get into the hikvision camera or the DVR's OS and change what is going on in there. i'm a helluva programmer and can do it, but I don't know what their OS's allow, or how far I can go to hack in. what I do know is I don't want to do anything in assembly.

i quite agree, it was, for forums, a pretty detailed and outstanding reply. I reckon a lot of people want these cheap, high quality cameras to protect their house as a security system. I wrote to HikVision and asked them about all these different features and told them their motion detection was really bad (a bee sets it off!). They wrote back (which was shocking in itself), and said, "We need to know where you bought your cameras before we'll talk to you". I told them, "I paid full price off Amazon Prime". They wrote back and said, "that is not an authorized dealer, we will not talk to you". I wrote to them and said, "I'm a principle engineer, in the computer vision department at Microsoft, we can make these cameras better at detecting motion and make a better product, just talk to me!" No answer. Go figure. There are a lot of things people could want to do w/ these cameras, and hikvision's stuff is really, really primitive. If there isn't an already-hacked up suite I can install with a bunch of security features and scheduling built into it, boy the market sure is ripe for one. Sounds like this might be my new personal project. Nice kudos, jerome.

people, not just myself, buy these cameras for a security system. not just for a cctv system. and the features I'm wanting aren't really all that fancy, with the exception of wanting better motion detection, they just haven't been implemented by Hikvision. I guess what I'm really asking is: Has somebody else already solved this issue and made a "better" security system? the only bits of hacking I was thinking I'd need to do on the cameras themselves is write a better motion detection routine, and when to turn on and off the camera's output stream (why bog down the network if the camera's not even supposed to be on). The hacking I thought I'd need to do on the DVR itself is monkeying with the schedules. But if, as you say, this is all possible from their SDK, that makes things a little different. Though it would be nice to be able to change this on the DVR. I'll go read up more about this stuff. thanks!
