How much does it cost to install a hotel surveillance system? 9 cameras, approximately 400 meters of wire

If it is a hotel surveillance, it must be a professional model. The price will be relatively expensive, about 700 for one unit! If it's too bad, you're afraid that something will go wrong in the future, and your monitoring is not clear, which will cause trouble, so you'll need about 6,000 yuan for 9 points, and then buy a computer, which costs about 2,500 yuan, plus some cables and so on. Yes, the total price may be around 9,000 yuan!
