server hardware recs? ~15cam ~8k

Post by xris »

Trying to setup for residential security with initially a handful of cams, to later have expansion capability for ~10-20. Specifically planning initially on harvesting 2 cameras from an old blue iris setup:
* amcrest 4k (8MP) bullet optical zoom poe
* amcrest 4k (8MP) turret

Was considering getting one/some of the 8k dual-lens cameras (e.g. amcrest) for wide e.g. garden & roof/driveway views & minimum of drilling to house eaves.

Have higher rez to see e.g. license plates in case shady business in front of the house & for ID'ing critters eating from my garden. Some of the views can probably save in lower rez (side/gate ingress points). Just guessing initially ~15fps. Interested in trying to keep at least days-weeks-ish of footage. I brick the cams/server from WAN and use a VPN tunnel if want to view remotely (i.e. no AI/camera-phone-home-nonsense/evil-cloud). Ergo local storage so just want ability to fit a bunch of TB. Interested in adding a bit of overhead re computer specs. Am comfortable with linux/docker, but haven't used Proxmox yet which seemed intriguing from forum comments. For other small servers I've used a bunch of ~$70-200 used minipcs, but these don't have specs for what seems like is required for the higher-rez multi-cameras as above (CPU/RAM/storage). I am more inexperienced re picking a used server, re seemingly like there are some gotchas with the architecture of used server hardware from ebay. If estimated 15 cams at 8k 15fps is there a rule of thumb re cores/RAM/storage? Any specific server series to checkout in this regard on ebay? Thanks for any thoughts comments.

Perhaps relatedly: does ZM team do service consultations for e.g. ~1 hr for these non-commercial applications?

fastest way to test streams:
ffmpeg -i rtsp://<user>:<pass>@<ipaddress>:554/path ./output.mp4 (if terminal only)
ffplay rtsp://<user>:<pass>@<ipaddress>:554/path (gui)
find paths on ispydb or in zm hcl

We do service consulatations.

I would expect you to have a lot of issues no matter what hardware you throw at it. At the end of the day, an 8k image is huge. You are going to need a ton of ram.

My 4k cam used to take over 200% cpu ... now I'm using a VPU so it's more like 30%.

You are going to need to get into go2rtc for live viewing etc.
