I've tried motioneye, zoneminder, shinobi cctv, blue iris, and frigate NVR.

I couldn't get motioneye to work, but I'll blame on me being a noob (especially at the time).

Zoneminder was stable but the UI is a bit weak and it doesn't have person detection to my knowledge. You can get around the UI by using homeassistant as a front end.

Shinobi cctv has the best UI, but I found it to be a buggy mess, person detection was difficult to implement, and it didn't play nice with homeassistant.

Blue iris is solid, but requires a license and windows. I have the least experience with it, but it seemed decent.

Ultimately, I landed on frigate NVR and it's my favorite so far. Its very solid/stable, has built in object/person detection with simple support for hardware acceleration, and UI is simple but passable. Personally, I use homeassistant as a front end for WAF, but the built in UI isn't bad and shows all your person detection events. Also, compared to all the above, configuration is done through a text file. While this may seem daunting at first, the manuals are very good and it becomes copy paste after the first camera (makes backups easy too).

For hardware, frigate has recommendations on their site. A cheap PC will do the job with ideally an Intel processor for hardware acceleration. For cameras, I've had the best luck with amcrest. Just make sure you throw whatever cameras you get on their own restricted vlan with no internet access. Feel free to reach out if you have any other questions.

Frigate is fantastic, easy to setup, very simple UI. And it makes use of 6th gen and up Intel HW acceleration for object detection and encoding, so it's fast and very light on CPU usage.

For hardware Reolink is pretty decent for low cost, their 4k cameras run around $80-120 and as far as I know all support RTSP.

I started with zoneminder. When it worked, it worked "OK".

Getting AI-based object detection working in it, felt pretty hackish.

After it stopped working a few times, without notifications, I ended up picking up a blue iris license.

Blue Iris, itself, has been 100% rock solid. Its only disadvantage, it requires a windows device to run it on. (Although- there IS a docker container which emulates it using WINE). But- overall, it has every feature you could ever want in an NVR, and its reliability is hard to beat.

I run it on a 100$ optiplex with an i5-6500 and 8G of ram. There is a dedicated 8T HDD for long-term storage, and a cheap 500G "burner" NVMe for caching content, and batching to HDD.

I also, run Frigate. Its object detection is quite well, and REALLY FAST. (I want alerts BEFORE somebody is already knocking on my door). It does have a lot of NVR functionality, however, its not on the same level as blue iris. But- it does work extremely well for object detection.

It's not the cheapest, but I have had very good luck with Synology. Works with almost every camera on the market, including everything that supports ONVIF or RTSP. Good client software for web, desktop, and mobile. Has tons of tweaks and features.

I had a look at a bunch of different software platforms and settled on Blue Iris. It takes some tweaking but it's cheap and has a heap of different configuration options. That being said, the surveillance station stuff in Synology NAS drives is really good too. Very plug-and-play.

Loving Frigate. Really straightforward and powerful. I use a couple Amcrest IP5M-T1179EB-28MM, very happy with them too.

I built a box with a standard PC case and a xeon v2 wfor zoneminder, and just slapped a second hand hyper 212 evo on there

I would say go for a v4 over the v2 because the efficiency is much better. You will probably just want 1 core per camera + a few to account for OS + container overhead, so more cores + efficiency is better here

I have some crappy reolink cameras through a unmanaged POE switch, up to a managed switch (cheapo tp link gigabit) so the camera and NVR are on one VLAN. I set some firewall rules in my eouter (edgerouter x) to let me connect to the NVR but block the cameras. Not ideal, but it works.

Perhaps better would be to use a NIC and connect directly to the unmanaged switch so there's no need to VLAN, but I'm not using this for anything crazy, and i can still get gigabit speeds to the NVR

Also using a used enterprise 6tb drive for storage. Works fine and has been going strong for a year. They're a fraction of the cost of a new drive, and are usually pulled well before theyre ready to fail

I've tried many, including QNAP and Zone minder in my RPi4. I've landed with Frigate on my RPI4. Works like a charm with 2 web cams. Much more than this and you will need a GPU like Coral but those are almost impossible to find. It's hooked up to Home Assistant for eg notifications.

Blue iris works quite well for me

Got a bunch of IP2M-841W and zoneminder, was kind of a pain to setup but it's working fine now. Zoneminder is virtualized on some cheapo hardware that was laying around.

Blink works well without the subscription if you buy the parts.

@jcg I use iSPY agent DVR running as a docker container in a VM on proxmox. It records 24/7 to a 2TB external drive mounted on the docker container. Its really lightweight and great for my use.
I was so impressed by the performance that I went ahead and paid for a premium membership to Agent DVR. I have a mix of cameras and it seems to work with all of them without issues.

I'm using raspberry pi zeros with motioneyeOS 😜 not the best hardware, but gets the job done on a budget
