How to choose to monitor the camera and video capture card?
Fourth: whether the direct wiring or wireless transmission to install. In addition to the expensive price, the wireless network does save the camera installation trouble and unsightly, but 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 cover the wireless signal, the transmitter (at the camera side) and the receiver (at the host side) to stay away from other electrical appliances to avoid interference, such as the use of wireless networks , There must be more than 2 times the price of the monitoring equipment. We recommend that, unless necessary, try to use wired transmission to install.
Second, the installation of monitoring equipment needs to be sure to install several cameras and determine the monitoring range and image quality of each camera. First determine the number of cameras to monitor, and then according to the specific circumstances to determine the camera lens monitoring range: the camera must be clear to the monitoring point of the distance and the need to monitor the area, as the clarity, Ai Wei technology that: analog monitoring system 700 lines Cameras, and network digital monitoring system, millions of high-definition camera prices are very cheap, can be selected according to actual needs.
Monitoring system installation first determine the existing computer to install the monitoring card (this method is now rarely used), or embedded hard disk video recorder to do your monitoring host. Use the computer to install the monitoring card, suitable for familiar with the computer installation, a professional staff on duty, more functional requirements of the place. But the computer needs 24 hours to boot, and easy to crash in the virus or poor heat and other issues; the use of embedded hard disk video recorder does not require professional knowledge, do not need to keep, the operation is very simple, like the use of VCD as convenient;
Fifth: on-site monitoring and network monitoring When you determine the monitoring system installation, to consider whether the need for network functions, that is to say if you need to monitor the site at any time to monitor and control, you need to select a network-enabled monitoring host The To avoid the installation is complete but no network transmission function.
