Which is better, video recorder poe or poe switch?

Which is better, a mobile phone with camera function or a SLR camera?

Professional photographers don't use mobile phones to take pictures.

Ordinary users will not buy Canon high-end cameras.

Generally speaking, if there are more compatible functions, it will be unstable, and its life and performance will be much worse.

POE video recorder can be used for more than three cameras, so it is recommended to use POE switch in the project.

I hope my answer can help you.
