Security monitoring products generally have what kind of trouble ah?
The quality of the product itself occurs in the decoder, the electric pan head, the transmission components and other equipment. It is worth pointing out that some equipment may not appear on the whole quality problems can not be used, but in some technical indicators can not reach the specifications given in the product specifications. Therefore, the necessary sampling must be carried out for the selected products. If it is a product quality problem, the best way is to replace the product, and should not be removed and repaired.
The incorrect connection between a device (or a component) and a device (or component) may arise in the following aspects:The impedance mismatch.No corresponding communication interface or communication mode. Most of this situation occurred in the control host and control keyboard decoder or a communication control relationship between devices, that is to say, the control of the host and the decoder or control keyboard is not a manufacturer of products caused by. Therefore, the host, decoder, control keyboard and so on, should choose the same manufacturer's products.The driving ability is not enough or beyond the prescribed number of connected equipment. For example, some image segmentation device with alarm input interface in the product specification gives the system host machine is connected with the alarm probe, long delay VCR connected system, if the alarm probe and connected to the image segmentation device the input end of the alarm, the alarm signal will appear to drive the probe and driving alarm host, image segmentation is the case. In this case, there is often a problem of insufficient driving capacity. Show the phenomenon is that the image segmentation device can alarm, the alarm signal input but due to weak and unstable work, resulting in a way that the corresponding image camera alarm signal on a monitor while instantly converted to full screen picture but lost (hold), and the image on the monitor is not before the alarm screen.
For some devices (such as PTZ cameras and lenses with three variable) has many links, if not handled well, especially with the equipment connecting lines are not handled properly, there will be open circuit, short circuit, wire insulation, as a result of adverse false wiring damage, the problem of declining performance equipment. In this case, according to the phenomenon of failure calmly analysis, to judge in a number of lines is due to what the connection of the line has problems, then produce that kind of fault. This will narrow the scope of the problem. It is particularly worth noting that with the pan tilt camera with a full range of motion, a long time, resulting in line off, break is common. Therefore, special attention should be paid to the connection between the equipment and the various lines of the equipment in accordance with the requirements of long time operation.
The incorrect power generally has the following several possibilities: power lines or power supply voltage is not correct, the power is not enough (or a road supply line size is not enough, the big buck), transmission line power supply system of the short circuit, open circuit, instantaneous overvoltage etc.. In particular, equipment failures due to power supply errors or transient overvoltage have occurred. Therefore, in the system debugging, before power supply, we must seriously and strictly check and check, should not be taken lightly.
