raspberry NVR

[Hout Vuur]

Hi, how many cctv camera's can you run on a raspberry pi using motioneye? I was looking to make a NVR with 4 hd outdoor camera's, is this an option? And i want wired camera's, what are good and affordable camera's to use?

Your answers depend on several things. I run 6 on my production system, 4 at 800x600, 2 as 1280x720. On my Intel i5, I get 15 frames per second per camera when all are recording at the same time (not viewing, recording). On a Pi3B+ I average 5 frames per second recording all 6 at the same time. Pi4 is slightly better at about 8 frames per second. I have gigabit ethernet to the Pi and i5, 3 cameras are ethernet, 3 are wifi (802.11g) As to camera suggestions, I can't make any. I use d-link 5020L, a Tiga Dashcam, and 2 Foscams. Nothing specifically for outdoor. In my test collection I have a number of PiZeroWs with PiCams in containers to test outside, or to take camping or Ham Radio Field Days for security cameras.

MotionEye is a wrapper for the program "Motion", and uses it for all motion detection.

I have 6 cam (1280x1024 25FPS) with Raspberry 4pi 4 Gb RAM.

First I set MotionEye with the same setting as cam does out of the box, this means MotionEye doesn't make any recalculation.

Then I use motioneyeOS, then MotionEye as addon of Home Assistant and now MotionEye as container docker.

Every configuration simply shows the limit of the CPU + GPU using motion, Raspberry with 6 cam is too weak.

Now I decide to move to a real NVR.

@StarbaseSSD thx for the reply.. Ok nice to know you are able to run six on a raspberry. I was thinking of using a pi 4, but maybe the framerate/resolution is going to suffer a bit? I've seen some youtube clips of usb webcams being used, nightvision is going to be an issue. Would i be able to use a POE cctv camera for instance?

@nicola.m... Ok, so a pi 4 is to weak for 6 in your opinion. Would 2 less make a difference you think?

Yes, you are going to suffer a bit, especially if you want high resolution and frame rates on a Pi4. Reduce resolution and framerate and it is doable on the Pi. For cameras, look at the iSpy Connect database. For PoE, you need a PoE switch, or PoE injector. Nice, to run a single cable to a camera, but IMO, not worth the extra cost in most cases. iSpy database: https://www.ispyconnect.com/cameras

well... less cam would be better obviously. I mean: the record triggered by motion detection isn't a problema itself, Just set privacy mask, filters and so on, notification via webhook also.

The problem (if we call this "problem" instead of "issue") is that CPU reach easily 60°C on fanless case and CPU load is around 95%

As sono as you stop the container with MotionEye suddenly temperature drops down to 45 °C and load is about 20%

This means 6 cams would be possibile but hardware of the Raspberry is near ti its limit. Obviously It is robust and don't worry for damages.

I'll check that database, thanks.

 was looking into a "real" nvr also but with the cheaper one's (i found nvr's with 4 camera's and 1tb hard drive for about 150,- euro) you don't know how long the software is going to be supported and if it is just a crap product qualitywise.

I run 5 cams, one with 1280x860, and 4 others with 800x600 resolution with 3 fps on a Raspi 4, 8 GB and a fan and when viewing the 5, I get a load of 1.4 in average and currently run it at temperatures of 47 deg C. That means that eventually a few cameras start lagging. Movement detection and recording does not seem to affect the load.

Thanks for all your replies 🙂👍 Makes it easier to make a good decision what route to take for my needs. The raspberry option has it's flaws for me i think, it's not going to give the performance i'm seeking. I have a pi running a NAS i'm very happy with but as a nvr it's probably not powerfull enough.

You can still use motionEye on PC hardware: https://github.com/motioneye-project/motioneye/wiki/Installation
