There are 4-8 cameras in the home improvement monitoring, which can be seen clearly from 50 meters away. It is closed during the day and open at night. Is it better to use the acquisition card or the hard disk burner? Hello, let's talk. It is suggested to use an 8-channel hard disk video recorder to directly connect the LCD TV in the living room. You can watch it with the remote control. After all, home surveillance can't be checked all day. If you have a hard disk, 4 heads of 500G can be stored for 1 month, and of course 8 heads can also be recorded for 15 days. In addition, wires can be purchased according to actual conditions. There are about 200 cameras and 600 lines. When buying, you should make it clear to the merchant that the lens is 3.6 mm-8 mm, and you should choose it according to your own illumination angle. If it is not suitable, you can consult with the merchant for easy adjustment! Indoor and outdoor power supply 15-20 yuan, BNC head, 1 yuan, 8-way hard disk video recorder about 380 yuan, 500G hard disk about 320 yuan, hard disk video recorder connected to TV VGA cable 15 yuan, video cable and power cable one meter one yuan, purchased according to the actual distance. In addition, the outdoor camera bracket,10-one in 20 yuan, needs about this much. You can calculate it when you have time. I hope I can help you. If you have any questions, please ask. Thank you!
