Second, wireless monitors are susceptible to noise and have a short transmission distance. Wireless monitors are easily affected by buildings such as cement, metal, wood, etc., and reduce the distance of reception. Therefore, even if the product label can transmit 100 meters (this label is usually the largest data of the measured results), it will actually be installed. The environment is different and reduced. Sometimes, due to factors such as the separation of buildings and building materials, the transmission distance may even be less than half of the nominal. The result of using the test in the merchant clearly shows that the transmission distance is very far, but when I buy it home, I find that the transmission distance is shorter, and this result will inevitably cause some disputes between buyers and sellers.
In addition, wireless monitors are also susceptible to interference and noise (even in a completely empty environment, it is difficult to avoid noise), so sometimes the image displayed on the screen is intermittent.
Third, the legal "wireless monitor" and "wireless video transmitter" volume can not be too small.
Legitimate wireless monitors (including monitors and audio and video transmitters) are made to standard, so the overall size can not be too small; and the legal wireless video transmitter (requires another monitor) has the smallest volume. So big, so if you want to use it in hidden camouflage, it is actually more difficult than using a wired dry bean type or a machine type.
Therefore, the difference between wireless and wired is only to save the wiring from the monitor to the screen. The power supply cannot be omitted. Therefore, it is not that the wireless monitor is a true complete antenna. In addition, the above noise and distance are added, so To be used in hidden camouflage, it is better to use a wired "domestic dry" monitor or "machine type" monitor for convenience and ease.
Urinal flush valve is made of brass, chrome plated. Press down for water, delay time 6 to 8 seconds, then automatic closed. It often use for hung Urinal in public washroom. Exposed type flush valve looks simple, easy to install and operate. Working pressure should be 0.05MPa to 0.9MPa.
