The video monitor is an important part of the surveillance system and acts as the "eye" of the surveillance personnel. With the continuous improvement of the security awareness of the whole society, the application of video monitors has become more and more widespread. Hospitals, subways, railway stations, airports, office buildings and other places are using it to take charge of security work. Video monitors that work almost continuously require more routine maintenance and care to extend their useful life. If you only use non-maintenance, the video monitor can also “eat it!†How can the video monitor be maintained?
First: Keep away from hard objects and avoid collisions
Video monitors are fragile and must be kept away from hard objects to avoid collisions. When cleaning the screen with detergent, wipe it gently with a soft cloth, because the liquid crystal display has little impact resistance, and many crystals and sensitive electrical components are damaged when they are hit.
Second: The use of the environment should be kept dry
Anything with moisture that enters the video monitor will damage the interior, so the monitor's use environment must be kept dry. If water vapor appears on the screen of the video monitor, it should be kept calm, and gently wipe it off with a soft cloth before starting it; if moisture has entered the inside of the monitor, the monitor can be placed in a place with high temperature and the internal The water evaporates; if there is too much water inside, ask the service provider to help them better and prevent damage to components and prevent permanent damage.
Third: often dust
Sweep the dust on the surface of the monitoring equipment. Cameras, protective covers, and other components need to be removed for thorough cleaning. Clean the lenses with anhydrous alcohol, and adjust the sharpness to ensure the normal operation of the machine. At the same time, all types of facilities in the monitoring room must be inspected. When the monitor is exposed to the air, static electricity generated on the screen will absorb many dust on the monitor, affecting the sharpness of the screen. Therefore, dust should be regularly cleaned and the color of the monitor should be calibrated. And brightness.
Fourth: Avoid long-running
Continuous use for a long time can cause the monitor's pixel crystals to age or burn out. Once damaged, it is permanent and irreparable. Turn off the monitor when not in use and avoid turning it on for a long time.
Fifth: Do not use screen saver
Screen savers not only fail to protect the monitor, but also cause damage. The glass substrate of the liquid crystal display is filled with moving liquid crystal molecules. The liquid crystal molecules of a liquid crystal display that is displaying an image are always in the working state of the switch. The monitor operates for one second and the liquid crystal molecules are switched several hundred times or so. The number of switches is limited by the lifespan, which causes the monitor to age due to its life. Therefore, when leaving the monitor for a long time, turning it off is the best choice.
Sixth: Regular inspection
The monthly regular maintenance can ensure the normal operation of the video monitor. According to the instructions for the use of various parts of the monitoring system, the technical parameters and the quality of the transmission line of the monitoring system are checked to eliminate the hidden troubles.
Seventh: Do not disassemble monitor
High voltage is generated inside the monitor. Disassembling the video monitor without authorization not only has a certain degree of danger, but also easily increases its failure and causes more serious damage.
The video monitor can not only monitor various places in real time, but also help the public security department to detect various types of cases and play a key role in the investigation. It is necessary to maintain and maintain it in daily life in order to make it "guard" and to serve our life for a long time.
Zowell XPC15 Pallet truck 1500kg is a material handling equipment mainly used in the transfer of materials in pallet inside and outside the production line and warehouse. The pallet truck is only used for plane transportation for no lifting mast. Although the pallet truck cannot lift the goods, but the purchase and maintenance costs are quite lower than other forklifts. Zowell XPC15 electric pallet trucks is equipped with AC drive motor and multi-functional handle, emergency switch, dual balance wheel as well as side loading battery for safety, efficiency and less fatigue in operation. Buffered pedal also extends the flexibility for various scenarios.
