Security monitoring equipment operation and maintenance services and maintenance
General video surveillance mainly consists of hard disk recorders, cameras, and monitors. So in the daily use of these security monitoring equipment will inevitably be a problem, only regular maintenance can let it play a greater performance.
First, security surveillance equipment operation and maintenance services Security system as a unified system, then after delivery, there is still the need for training, maintenance and follow-up upgrades and expansion of the building needs, you can also use services to operate.
1, training services: training services in the domestic market due to the multi-platform software contractors to provide free, but no more than good conduct, applicable also affect the quality of the project delivery. Many of the security system construction plans and concepts are very advanced and highly integrated, but after delivery, due to the low level of operators, coupled with the flow of personnel and other reasons, many security systems have not played a role. Some role, so training is a big market, there is a lot of room for improvement.
2, system operation and maintenance services: system maintenance services primarily in the security system construction is completed, some of the routine maintenance of the system after delivery, such as inspection system or system troubleshooting. System operation and maintenance services are the main service market for security platform software companies, and they are also the most direct market. However, they are not done well at present. Many engineering integrators do not have the ability to do so, and platform software providers have relatively no money to make, and not Develop this market.
3, transformation, upgrading, expansion of services: the operation and maintenance of a system in the course of time, over time recommendations, product upgrades, equipment aging and software updates and other reasons, the system will have the transformation, upgrading, expansion and other needs This market has already been discovered by everyone and started to dominate the competition by platform software.
Second, the camera's maintenance and maintenance of the camera is a precision home appliances, whether it is on the circuit or mechanically than other home appliances and more sophisticated, use should also pay more attention to prevent the occurrence of failure and prolong life. In general, special attention should be paid to the following points:
1. Pay attention to moisture: Wetness is the enemy of the camera. High humidity can cause rust in the metal part of the camera, circuit short circuit, moldy lens in the lens, etc. Extreme conditions can form drops of water on the surface of the drum. When the tape is put into the tape, the tape is stuck on the drum, and the tape and the machine are damaged simultaneously as the drum rotates at a high speed. Therefore, the camera should pay attention to moisture protection at all times. It is better to put a little moisture-proof agent in the bag where the camera is stored. In winter, it is best to put the camera in a warm environment for 30 minutes before using the camera. Avoid splashing water when using by the sea and on rainy days.
2. Take precautions against vibration: Vibration will have an adverse effect on the mechanical parts of the camera. The mechanical parts of today's digital cameras are very precise. Some mechanical components have a thickness of less than 0.5 mm, and the positioning accuracy of their guide posts is calculated in micrometers. Therefore, strong vibrations sometimes cause mechanical misalignment and even loose circuit boards. Therefore, strong vibration should be avoided when using it, especially to prevent the machine from falling to the ground.
3, pay attention to dust: the camera's drums are relatively small, and high speed, especially digital video cameras, its drum speed up to 9000 rpm, such a high speed, if the head encounters dust inside the machine, sometimes subject to Damage; At the same time, dust in the machine can cause immediate blockage of the head and affect the quality of the image taken. Therefore, when using the camera, you should pay attention to dust, and try to avoid using it in high dust environments such as wind and sand.
4. Pay attention to protection against electric shock: It sounds a little unintelligible and the camera can be shocked. It is. Unlike other appliances the camera, often with the monitoring device such as a television, a recording apparatus such as VCR is connected, the digital video camera often now as a computer is connected. If the connected device is leaking during the connection process, the camera can be easily burned during the connection process, and even if it is serious, the camera may be scrapped! Therefore, it is better to connect the above device when the power plug is unplugged. So as to avoid unnecessary losses.
5. Digital video cameras should not be used continuously for a long time: People using digital video cameras may feel this way. After a long time, the machine is often very hot, and some places are just hot. This is because there are a lot of digital cameras. Digital circuits, which generate a large amount of heat during operation, have a compact digital structure and do not easily dissipate heat. Excessive heat buildup can adversely affect the soldered portion of the circuit portion. Therefore, after the digital camera is used for a period of time, turn off the power and let the machine cool down before use. In addition, home video cameras should not be used for other purposes such as monitoring.
6. Do not use tapes that are too old: Old magnetic tapes have a large amount of magnetic particles due to their high frequency of use, and magnetic particles that are detached during use are likely to cause blockage of the magnetic heads and should be avoided.
7. In any case, do not use the external power supply specified by the manufacturer and the power supply device other than the battery. In particular, some batteries and batteries sold on the market, even though their nominal voltage meets the power requirements of the cameras, the no-load voltage of some batteries just when they are full is very high, and it is very easy to burn the machine when it is connected to the camera.
