How much is the monitoring and maintenance fee of chain hotels generally charged and how to calculate it?

Generally, it is 3%-5% of the project cost, but judging from your 3000 yuan, it is not high on the surface, but it also shows that the project quality should not be very high! 350 yuan a head also means that the monitoring over there is not so good. You use a very ordinary camera, even if it has infrared, it is very cheap. The effect is not good. But it basically meets the needs of monitoring images.

Generally speaking, there is nothing wrong with the price. Just the quality is not high! In fact, there are many devices that need to be maintained, including on-line, on the back-end hard disk video recorder (or computer), on the power supply, and the dust removal of the devices should also be included. Good cameras rarely go wrong, and most of them age in the power supply of 12V or BNC head. Basically, the annual maintenance fee is a very profitable profit!
