ZoneMinder Scripted Backup and Restore I'm getting ready to replace a boot hard disk on my Raspberry Pi 4b ZoneMinder system and have tested a scripted backup/restore. I have not found anything out there that does a full ZoneMinder backup and restore to a remote backup server. I created a sandbox ...

This is the Zoneminder process loads for a 5 MP camera, Monitor 3 is the low resolution motion detection video and Monitor 4 is the high resolution video linked to it with decoding disabled.

This is the Zoneminder process loads for the 8 MP camera, Monitor 1 is the low resolution motion detection video and Monitor 2 is the high resolution video linked to it with decoding disabled.

Below are the system CPU utilization and Gigabit Ethernet utilization for all three cameras:
I estimate the Raspberry Pi 4 can handle 8 high resolution cameras operating at or near their maximum frame rates and resolutions.

I did a fresh install of Zoneminder 1.36.10 on a Raspberry Pi 4 to take advantage of the ability to disable decoding of my cameras' 5MP and 8MP video streams and link them to the VGA streams for motion detection. My previous Zoneminder 1.34.x installation had CPU bottlenecks, and 1.36.10 freed up a ...

Hello, can you please update on your experience since then? Can you post some pictures/screenshots of your setup? I'd like to bring up a similar system, but with mocord mode; 1-4 5MP cameras. Did you manage to overcome 1080p limit? Thanks. I'll put something together with Zabbix monitoring graphs ...

For 4 - 8 5 MP cameras you will need multiple Raspberry Pi 4 8 GB models, likely 3 - 4 cameras per Pi, depending on frame and bit rates. My original setup is here: https://forums.zoneminder.com/viewtopic.php?f=10&t=29853 However, the SD Card was a bottleneck, so I updated the Raspberry Pi 4 firmware ...

I set up one each Amcrest 5MP and 8MP cameras as per this older post: https://forums.zoneminder.com/viewtopic.php?f=10&t=29853 However, I monitored it with zabbix and determined there were still hardware bottlenecks on the Raspberry Pi 4; the SD Card IO bottleneck was the critical issue because I ...

I just set up a Raspberry Pi 4 8 GB for Zoneminder and it appears to be a viable three-camera server. I am currently in dev mode and it is writing video to the SD card, but I will move it to a USB 3 disk enclosure in the future. That may add some CPU IOWait time, but I doubt there will be ...
