From what I know, it is not possible, at least not with this NVR. It's not even close to having enough power to fully process the stream for motion detection. However, I did not try, as I only need this as a relay for viewing cameras and some continuous recording.

Sorry for the incomplete response: that's how I did it after the previous post showed me how....

Yup, that's how I did it. Thank you!

Hello, Is there any software like Hikvision Remote Backup that works under linux? I am trying to backup the microsd recordings from several 2732 cameras. Thanks!

I guess I can do ONVIF, but I do not want the NVR to grab the main stream, which is high res-high bw, but the substream. Is there a way to tell to Hikvision NVRs to grab only the substream? RTSP would have been an easy way, as I would just add the substream URL and that's it. Thanks!

Hello, Is it possible to add cameras via RTSP stream only? I know there will be no features like motion detection, but I am not interested in that. I just want continuous recording. Thanks!

Hello, I have several DS-2CD2732F-IS setup in a low bandwidth location and I would like to restrict certain users to have access only to the substream. Is that possible? Thanks!

Thank you!

That's perfect, thanks! Unfortunately, almost all clients are mobile. I do not see that option on iOS. Does anyone see it on Android? Thank you again!

What do you mean by "ethernet data"? Adding 32 cameras on 20 devices might be an easy task for some, but not for me. Please try adding 32 cameras on your cell phone and let me know how you are feeling after you are done. Then multiply that with 20. <- THAT is what I want to avoid by using the NVR. Please try coming up with a solution, not with sentences like "why do you want to do that?" "I find it strange that you want to do that" etc. Otherwise, please do not pollute this thread. I believe my request is quite clear and my reasons are also quite clear. Thank you!

That depends on how your perimeter looks and about distances. Forget about putting 1-2 speed domes in the middle, as you will not see the fence, unless you are very very high, which translates into shadow for pannels; at least people I worked with do not accept this kind of shadows. Hikvision and Dahua have very nice speed domes, with long range IR. I have installed Hikvision (20x optical zoom, 100-130m smart IR), which work fine, but they are blind over 150-200m during the night, if you do not have some IR illumination that's closer to the targeted area (if that area is beyond 100m). Also, if there is fog, speed dome cameras are quite useless. Pay attention to the fact that the solution you are looking at does not have backup. Also, you have no idea if a PIR is defective or not, since you do not have a secondary system that will alert you. You might have gaps in perimeter and you have no idea about it. Use a mw barrier (take a look at Predix) or a vibration detection cable that's put on the fence all around. The latter is actually quite popular in this solar field, but it might get you a lot of false alarms, even with the meteo station (without that you are screwed anyway, as any wind/raid will trigger it). Bottom line: do not rely on a single system, as you will have no idea if you are really protecting your site or not.

Big guys in this area use normal cameras (well, not just any brand!) combined with outdoor PIRs. They sell appliances that are aware of both these and integrate them to minimize false alarms. However, I find this way too expensive (5 zeros price for real systems, not diy stuffs), since you need cameras installed each 50m, in order to be effective and the poles should have a very limited move due to wind load (just a few mm at top), in order to reduce false motion detection. Then add communication redundancy, power supply backup Just motion detection from cameras is a total no go, since you will have tons of false alarms. And no backup if a camera fails. After installing 2 system like this (for solar power plants), I would say give up cameras and use outdoor PIRs and microwave barriers (again, serious stuffs, not jokes). Install cameras just for verifying the false alarms and status of the fence. If you get into thermal vision zone... you're talking big numbers too,if you really want to cover such a perimeter. Thermal cameras are not cheap. I've seen "budget" solutions, with a central camera... what a joke. And imagine that camera goes down... you are on your own. Good luck!

I know that. The problem is that, once you add the camera into NVR, NVR starts streaming from all cameras, no matter someone is watching or not, if it is recording or not. Again, I do not record anything on the NVR, it is used just for live view.

Hello, I've installed a Hikvision 7732NI-ST with 32 Hikvision cameras, just to use it for live view (no recording). How can I have the NVR get the streams from cameras only when that camera is viewed by a NVR client? That would save me a lot of bandwidth, as most of the time noone is watching them. I just want to use the NVR so I do not have to add 32 cameras to all the viewers that need it. Or, if that's not possible, is there another way of doing this? Thanks!
