electronic monitoring system is planning to 24 hours of homework, and in all client device quality will directly affect the system operation performance and life. Therefore, it is necessary to notice the following basic requirements for monitoring and control system device. 1, control rod line maintenance in system power surge input equipment maintenance is with characteristic of all successful system. Despite the many security system are using UPS, but demand note is not all of the UPS with built-in surge maintenance. Similarly, video and data lines also needs to maintain. 2, monitor the quality of the cable quality CCTV coaxial cable, RG59U, RG6 and RG11 requirements is 100% copper, and 95% of the copper braid shielding layer. Pick up line ring larger resistance should not exceed 15 ohms. 3, monitoring of ground loop correct earthing can put the loop down to little effect. The voltage difference between different grounding should not exceed 100 mvac ( Measuring coaxial cable to disconnect and shielding layer and equipment BNC behind the pressure differential between the earthing terminal) 。 4, control rod interference/EMI and RFI exposed to any trouble environment will decline video quality and affect the system's overall performance and reliability of products. Avoid equipment exposed in the large Ma Daru elevators, water pumps and fluorescence column, and all kinds of high power radio equipment environment. 5, monitoring system equipment work environment security system of equipment requirements device in the clean air conditioning room, and ask the device in the 19th & quot; Standard rack, should leave proper space between equipment, the use of forced ventilation fan. 6, control rod digital video video right backup process if the hard disk video recorder fixing or promotion, there maybe lost the original program and all the information in hard disk. The maintenance center can not ensure that can restore the data. Hard disk backup is the responsibility of each user, here, let's claims that the user to the hard disk backup on a regular basis. Please let make a backup of all users aware not may cause potential problems.
