Details for wireless monitoring systems.
I. Device monitoring equipment requirements Confirmation is required to install several cameras, and confirm the supervision scale and impression quality of each camera. First determine the number of surveillance cameras, and then confirm the lens surveillance scale of the camera based on detailed conditions: a clear interval between the camera and the monitoring point and the area to be monitored. As for clarity, we think that a 480 TV line camera is sufficient.
Second, whether there is a night vision function. If Shenzhen monitoring equipment is installed in the dark places such as corridors, halls, aisles, warehouses, you can consider infrared night vision cameras. What needs to be noted is that infrared cameras in addition to professional night vision or In addition to special order, infrared cameras also require light-assisted five-finger on-site conditions, the infrared interval will be doubled. If the scene is a garden lawn, the infrared effect is even worse.
Third, the direct wiring is still the choice of wireless transmission to the device. In addition to the expensive price, the wireless network does save the trouble and unattractiveness of the camera device, but it is necessary to pay attention to the problem of spacing and obstacles. In principle, cement building materials will shorten the wireless transmission interval, and metal materials will completely shield the wireless signal. The transmitter (on the camera side) and the receiver (on the host side) should be kept away from other electrical appliances to prevent interference. If you want to choose a wireless network, There must be Shenzhen monitoring equipment that bears more than twice the price. We recommend to use wired transmission as much as possible unless necessary.
Fourth, do not rush to the on-site installation when you get the monitoring, first debug it in the computer room, and then install it. Check that the equipment's accessories are complete. The wireless monitoring system device first decides that the existing computer is equipped with a monitoring card, and it is still an embedded hard disk video recorder as your monitoring host. Using computer device monitoring card, the overall investment is relatively low, suitable for places familiar with computer devices, professional staff on duty, and more functional requirements. The computer needs to be turned on for 24 hours; using embedded hard disk video recorders does not require professional knowledge, does not require on-duty, and the operation is very simple, as convenient as using VCD.
V. On-site monitoring and network monitoring When you confirm the installation of the monitoring system, you should consider whether you need network functions, that is, 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. Prevent the device from ending without network transmission.
