Please post debug output in code tags. Try: mysql -uroot -p < /usr/share/zoneminder/db/zm_create.sql mysql -uroot -p -e "grant all on zm.* to 'zmuser'@localhost identified by 'zmpass';" mysqladmin -uroot -p reload Note that this makes the pw zmpass. Your configs for zm should also have the...

Start with syslog and dmesg. Please post logs in code tags.

DB connection refused usually means Mysql is not running (or bad password).
Please post some logs.

Ok, in that case unpack the .deb file and review the installation scripts. One of those steps failed. Alternatively, you can review wiki install steps (go to the history, as the old ones get updated) and you should find the manual creation steps needed there. Something like (this is an example of th...

After reading your post again, I see you were only updating, not installing. Disregard what I said about the install steps. Occasionally the update db script will fail halfway. It's common. Just run the update command manually. It can take a while for large DBs. # zmupdate.pl edit: this is wrong, se...

ZM used to have some install steps executed by the user (creation of mysql db, permissions for db, apache enables, etc) but these are now handled by the dpkg install script and (the controversial) init. These steps are still in the .deb file, and if you download the package and extract. you will fin...

For cores vs core speed, I can't answer that. How do the CPUs compare? Try one of the online comparison sites. What is the release date of each, and also what tier are each. High end server CPUs will have more features than low end server CPUs, so even older CPUs that are higher end than say a new d...

It's likely going to be similar to a webcam. Some /dev/video or similar. When you connect the camera, what does dmesg say?

Also, refer to webcams in the https://wiki.zoneminder.com/Hardware_Compatibility_List

Just so we don't confuse anyone, by not using ZM as a client, I believe you two are referring to running X on an RPI. There is another way of using ZM as a client, which entails watching a video stream running by a ZM server where the RPI only connects into the ZM server but is not the server. That ...

Resolution and FPS are set on camera webpage.

Don't set Max FPS in Zoneminder (exception is local cameras - i.e. webcams).

Lower FPS and / or lower resolution of camera

GPU is generally not used by ZM (with some caveats in newer versions). Don't focus on GPU. For the CPU, you listed a 4 core standard motherboard (I see it compared to i5 in reviews). If I had 25-30 cameras at 7-10 FPS, I'd get a server motherboard with 16 cores (although 8 may be enough). I have a 4...

See https://wiki.zoneminder.com/Beginner_hardware You get what you pay for. You may be able to use a webcam, also. For $200 you can get a decent brand name ip camera that has 1080p (or even 2K). You can possibly buy used. Keep in mind that some cameras don't have IR by default. If you are indoors, a...

The hardware specs tentatively look ok, however the performance will depend on what resolution and FPS your cameras are at. In addition, there are things to consider like whether you are using H264 passthrough, or MJPEG recording. If you expect 26 cameras at 720p with maybe 4FPS, I'd say you are ok....

To display to a monitor, is handled differently from traditional DVR boxes that have an HDMI output. You can spin up a separate machine, and have that watch the screens from the LAN.
