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.
