3G Mobile DVR With Bus People Counter Kit is facing technical problems:
And for multi-purpose 3G Mobile DVR With Bus People Counter Kit, than the two types of 3G Mobile DVR With Bus People Counter Kit equipment has a richer function. In addition to the features mentioned in the two devices mentioned above, the multi-function vehicle DVR also has GPS positioning, and the function of the vehicle driving recorder. In particular, with the development of audio and video signal compression technology and the increasing progress of the network environment, the vehicle monitoring equipment is connected with the control center through the wireless network, so that the situation of the vehicle can be grasped in real time and the crisis in the running Timely processing, with the fastest speed to ensure that the Secretary by the safety of personnel, but also gradually from the ideal to become a reality.
Relative to ordinary DVR equipment, although they are not much different in the function of the difference, but due to the different carrying environment, and therefore put forward higher requirements for technology. This is mainly reflected in the shock, power regulator, and environmental resilience in several areas.
As the vehicle in the process of driving, it is difficult to keep the vehicle to ensure stability and balance. Therefore, too much vibration will bring DVR device hard disk head dislocation, resulting in the problem can not be normal video. If the side effects of vibration is too large, then there will be control failure, damage to the motherboard components of the vicious consequences. Causing great damage to the equipment. Therefore, the 3G Mobile DVR With Bus People Counter Kit relative to the ordinary DVR equipment, in addition to the structure of the shell to meet more shock demand, the process also has a higher than the requirements of the general DVR. In addition, in the car on the 3G Mobile DVR With Bus People Counter Kit also use more special technology to maximize the loss of data loss or damage to the risk of equipment.
In addition to the high requirements of the anti-shock function, the ability to adapt to the power supply is also an important test of the 3G Mobile DVR With Bus People Counter Kit, because the car's power supply system is the vehicle in the engine work process, through the engine power generation and transmission to the battery for storage and distribution, The stability of the power supply is undoubtedly worse than the ordinary power supply. This requires a stable power balance between the output voltage of the vehicle and the DVR. Only in this way, can we guarantee the stability of the DVR system, and will not be due to power problems such as downtime can not work properly.
