With the video transmitter and receiver used, wireless video conversion is possible. Most wireless surveillance cameras are equipped with a built-in video transmitter and a separate video receiver. Once the wireless pass-through receiver is installed, it is directly connected to a security monitor, and the video signal of the interval camera record or other components of the surveillance network camera system in a more complex system will be sent.
Should we use a wireless surveillance camera? This is a surveillance camera system designed for a common problem. The answer to this question does not seem to be that simple. All wireless surveillance cameras look like a simple solution, and no extra cables mean more cost savings. But this is not the case. Before you make such a decision, there are a few things you need to know about wireless systems. Wireless surveillance network cameras are not completely wireless, we can't just look at their names because it simply refers to video signals. Even if there is no wireless surveillance camera required for the video cable, it still requires power, which means that the camera needs a cable. If there is no power outlet near the camera, you must install the power socket to make the camera work properly.
In addition, when using a wireless network camera when designing a system, the number of frequencies available is limited. Most wireless surveillance cameras have 4 different frequencies. This means that the frequency range in which you use four cameras is limited at each location. Fortunately, there are combinations of cameras from two frequency ranges that can expand the number of cameras in each position to 8. Just like many other wireless devices, you may be familiar with the fact that transmitters and receivers between different objects can cause reception problems. Received by the ideal range of metal and clear line of sight material. Therefore, when designing a wireless surveillance system, keep in mind that the number of walls or objects between the wireless surveillance camera and the receiver is kept low to achieve the desired reception.
Now that you have a better wireless surveillance network camera, you should be able to decide that future wireless surveillance cameras are the right choice for you. If so, you can use countless applications. They can be used almost anywhere, but the common one is covert video surveillance. Such as bank cameras, lobby cameras, museums or surveillance high-value objects, because it makes it difficult for intruders to find monitoring devices, so it is impossible to align and destroy.

Water treatment Filter Element is a filter element used for water treatment and liquid filtration. It is mainly used to remove suspended solids, sediment, rust and other impurities in water, and improve the cleanliness and transparency of water. The filter element is divided into the following types: PP filter element is also called PP melt-blown filter element, which is a filter element made of polypropylene material, which has good filtering effect and corrosion resistance, and can be used to purify tap water, groundwater, chemical liquids, etc.; The wound filter element is refined by finely winding textile fiber yarns with good filtration performance on a porous skeleton. The yarn materials include polypropylene fiber, acrylic fiber, absorbent cotton fiber, etc. By controlling the winding tightness and thinness of the yarn during winding, filter elements of different precision can be made, which can effectively remove suspended solids and particulate impurities in various liquids, and have a high purification effect on various liquids; folded filter elements , is a deep filter core folded structure, large membrane filtration area, large flux. Low differential pressure, strong dirt holding capacity and long service life. There are a variety of filter fineness to choose from, with a wide range of applications. Good chemical compatibility, suitable for filtering strong acids, strong alkalis and organic solvents. Processed and formed by hot-melt welding technology, does not contain any chemical adhesives, no leakage, no secondary pollution.
