Common problems in home monitoring and solutions

With the development and popularization of high technology in today's society, security products have entered various public places, such as schools, enterprises, shopping malls, and governments. Everyone is using high technology to safeguard and safeguard their work. Now, the security awareness of the whole society has been improved. Security products have been recognized by the family and started to be used. Many families now have video doorbells installed. This kind of video doorbell is passed by outsiders when the doorbell rings. The monitor in the house can see the specific situation outside the house; the video doorbell plays a certain preventive role for family safety, but there are also certain problems in using this kind of video doorbell in the home.


Houses that can't be wired for renovations The video doorbells that are 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 line routing. This makes it very 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.


Wireless voice and video transmission systems solve this problem in the face of the problem of unwiring. It is recommended that these homes can use ultra-compact wireless voice and video transmission systems. The sound and images of the door can be displayed through the TV. The micro-camera can The sound monitoring function is installed in the appropriate position of the gate, and then the signal is transmitted through the wireless video transmitter. The wireless video receiver can send the received sound and image signal to the AV input socket of the TV set. After the doorbell is ringing, just switch the TV to the AV state and you can see the person coming from the doorway 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 false color is that the price of false color is low and there is a phenomenon of dynamic tailing. If the monitored screen changes rapidly, 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 without dynamic tailing, and better performance, but the true color type is more expensive and can be selected according to its 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.
