How to wire the hotel monitoring?

In fact, I suggest you adopt a wireless solution, which is relatively concentrated anyway.

Cameras can be powered by poe for easy maintenance, or they can use their existing network.

Of course, if the camera doesn't support it, it can be transmitted by twisted pair, at least more convenient.

As for how to lay the cloth, how can we make it clear? The principle of proximity should be adopted, and grounding, conduit and marking should be done well.
