By the way, how much does it cost to install 14 surveillance cameras in a community?

Take the 400W HD webcams of Haikang and Dahua as an example.

A camera 400 yuan X 14=5600.

Haikang 16 Road 4 HD video recorder, 800 yuan.

A 3TB monitor-grade hard disk costs about X4=2800 yuan in 700 yuan, and 14 cameras can store 1 month's video for 24 hours.

Power adapter 12V2A, at most one X 14=280 in 20 yuan.

Ordinary supports and pipes for other wires are 2000 yuan.

Labor cost 1000 yuan

5600+800+2800+280+2000+1000 =1,2480 yuan.

The 4-meter-high stainless steel pole of the monitoring vertical pole is regarded as a 220 yuan, and if it needs to be counted separately,

At least 1.5 million should be prepared. If you quote, it depends on whether you still need monitors, cabinets, patch panels, outdoor rain-proof junction boxes and long-distance optical cables. If you want all these, more than 20 thousand is the normal quotation.
