Purely direct copy I just hope to help the installation of the monitoring system first decide whether to install a monitoring card on the existing computer, or an embedded DVR as your monitoring host. The use of computer installation monitoring card, the overall investment is relatively low, suitable for familiar with computer installation, professional staff on duty, more functional requirements of the place. The computer needs to be turned on 24 hours a day; The use of embedded DVR does not require professional knowledge, does not need to be on duty, and the operation is very simple, as convenient as using VCD; Secondly, the installation of monitoring equipment needs to determine how many cameras to be installed, and determine the monitoring range and image quality of each camera.
First decide the number of cameras for surveillance, and then determine the lens monitoring range of the camera according to the specific situation: it is necessary to clarify the distance from the camera to the monitoring point and the area that needs to be monitored, as for the clarity, we think: 480 TV line cameras are enough.
Third: whether to have night vision. If your monitoring equipment is installed in the corridor, hallway, aisle, warehouse and other places with low light, you can consider the infrared night vision function of the camera, it should be noted that in addition to the infrared camera professional night vision or specially customized, the infrared camera also needs to be on the scene under the condition of lighting auxiliary five fingers, the infrared distance will be doubled.
If the site is a garden lawn, the infrared effect is even worse. Fourth: whether it is directly wired or installed by wireless transmission.
In addition to the expensive**, the wireless network does save the trouble and unsightly installation of the camera, but you need to pay attention to the problem of distance and obstacles. In principle, cement building materials will shorten the wireless transmission distance, metal materials will completely block the wireless signal, transmitter (at the camera end) and receiver (at the host end) to stay away from other electrical appliances to avoid interference, if you want to use wireless network, you must have more than 2 times the burden of monitoring equipment. We recommend using a wired transmission for installation unless necessary.
Fifth: on-site monitoring and network monitoring When determining the installation of the monitoring system, you should consider whether you need network functions, that is to say, if you need to monitor and control the monitoring site at any time on the Internet, you need to choose a monitoring host with network functions. Avoid installing without network transmission capabilities.

The first is wiring, there are no specific requirements, as long as it looks good and there are no bare wires. To install the camera, you need to pay attention to the installation of the camera, the location is selected, and it cannot be exposed to rain (except for rainproof). Then there is the welding of the BNC (**) head, which cannot be soldered.
Finally, the power cord can be connected, and the connection needs to be wrapped with insulating tape. That's it, and that's it, and you're waiting to experience it in practice.

Pro, how to install monitoring methods for novices: Step 1: First think about whether the monitoring card is installed on the existing computer or through the embedded DVR, that is, first decide what the monitoring host is.
If you choose the existing computer for the installation of the monitoring card, the funds spent at this time will be relatively low overall, if you are more familiar with the installation of the computer, or all the more professional staff on duty in the monitoring field, you can also install the place where the function requirements are more, you can use the existing computer to install the monitoring card, and the computer under these conditions needs to be turned on 24 hours a day. If you choose the embedded DVR as the monitoring host, you don't need too much professional knowledge, and you don't need to be on duty, and the operation is also very simple and convenient, similar to the VCD used at home. Step 2:
After selecting the type of monitoring host, the selection of the camera, first of all, to determine the installation position of the camera and its monitoring range and the image quality of the camera, after selecting the camera, and then decide the number of cameras to be installed according to the installation needs, after selecting the camera, according to the actual situation of the installation location, the installation of the camera needs to consider the monitoring range of the camera lens, and the distance between the camera and the monitoring point and the area that needs to be monitored must be mastered enough, The approximate parameters of the camera lens are then calculated according to the corresponding formula. The clarity of the camera can be set according to the need, and it is best to use a camera with a 420 TV line. Step 3:
According to their own needs to determine whether the monitor should have night vision function, some geographical locations need to consider the installation of infrared night vision function of surveillance cameras, such as corridors, aisles, warehouses, hallways and so on. When using infrared night vision surveillance cameras, you need to pay attention to the fact that if there are lights on the scene, the infrared night vision function will be reduced, or even doubled, such as garden lawn and so on, unless it is a specially customized infrared night vision monitor. Step 4:
Decide whether to use a wired network or a wireless network. Wireless networks have many advantages, it can save a lot of trouble, and it looks very beautiful, but compared with wired networks, it is more expensive than confession, and you also need to consider distance and obstacles. If you use a wired network, it is cheaper and suitable for the general public.
Step 5: Decide whether to use on-site or network monitoring. Compared with the two, network monitoring is more convenient, and only need to connect to the network to achieve monitoring.
Network monitoring installation experience and precautions in the network cabling, whether it is a super five category network cable or six types of network cable, the transmission distance can not exceed 100 meters, more than 100 meters should use a switch as a relay, or use a network delayer, the distance is too long to directly choose single-mode optical fiber transmission, single-mode optical fiber transmission distance can reach dozens of kilometers.
