Visual doorbell installation problem solved!

First, the family completed the decoration can not be wiring

The visual doorbells currently on the market are generally wired. For those families that have not been renovated, they can set aside pipelines for image transmission. However, for homes that have already been renovated, there are no pipes left for routing. This makes it difficult to arrange cables for video and audio. This problem is still present because many families are in the process of renovation. There is no visual doorbell, and there is no pipeline that leaves the route ahead of time, and the wiring cannot be performed.

Second, wireless sound, image transmission system to solve this problem

In the face of the problem of unwiring, it is recommended that these families can use ultra-compact wireless sound and image transmission systems. The sound and image of the entrance can be displayed through the TV. The micro-camera can be installed on the gate with sound monitoring. In the right place, and then through the wireless video transmitter to send the signal over, the wireless audio and video receiver can send the received voice and video signal to the TV's AV input socket, so that after hearing the doorbell, just switch the TV to AV The state will be able to see the person at the entrance and hear his voice. Some families are not accustomed to driving a TV set. However, when the doorbell rings, it is troublesome to turn on the TV again. They do not want to use a TV as a monitor. For such a situation, you can purchase a LCD monitor for special monitoring. The size of the liquid crystal display does not need to be too large, 4 inches or 5 inches can be, too expensive and expensive, there is also a large footprint. The liquid crystal display on the market is divided into true color TFT and pseudo-color STN. The difference between true color and pseudo color is that the price of false color is low and there is a phenomenon of dynamic tailing. If the monitored screen changes quickly, the image is displayed. It will be very vague, this is mainly a long dynamic response time, pseudo-color type is not suitable for displaying TV pictures or VCD, but for some image changes are not severe places, such as general security monitoring can use pseudo-color type, and Monitoring with pseudo-color can be said to be inexpensive. Compared with the pseudo-color type, the true-color type image has bright colors, wide viewing angle, no dynamic tailing phenomenon, and better performance, but the true color type is more expensive and can be selected according to its own economic situation.

Through this wireless sound and image transmission system, the problem of no video doorbell being installed after most home renovations has been solved; there may be many problems in the security monitoring work in the home, but it is believed that these developments through science and technology The problem will be solved very well.
