As the urban population continues to increase, public transportation security pressures increase. Governments around the world have stepped up their investment in transportation security, which has also increased the demand for mobile surveillance solutions. According to the research reality, the mobile video surveillance market reached 1.55 billion U.S. dollars in 2015, and the compound annual growth rate from 2008 to 2015 was 13.7%. Mobile surveillance not only enhances the safety of drivers and passengers, but also improves the efficiency of fleet safety management.
However, for mobile surveillance, video storage device requirements are higher. The mobile hard disk recorder is an important device for vehicle monitoring. The demand for mobile hard disk recorders has increased dramatically. Since 2011, China has stepped up efforts to promote the public safety and mobile surveillance market. With the gradual improvement of people's living standards and the increasingly complex social environment, mobile surveillance has become an important element for the people's safe life.
In general, law enforcement vehicles need to be quickly and effectively tracked and recorded. Transport vehicles need to be located and tracked remotely. Obviously, mobile hard disk recorders will encounter a huge market, mainly applied to logistics transportation and financial escort.
The mobile hard disk video recorder uses an embedded operating system. The DVR supports professional digital audio and video encoding and decoding technology. The embedded processor is combined with an embedded operating system to ensure the stability of the equipment; high-quality compression and decompression are used in GPS and 3G. Under the role of wireless communication and mobile power management technology, all functions are realized.
As a traditional embedded DVR market, the mobile hard disk recorder is an emerging product that also joins professional audio and video coding technology applications and vehicle monitoring systems. It integrates GPS, 3G and USB communications to meet a full day of vehicle monitoring. demand.
2 Mobile DVRs need to break through the bottleneck
Mobile hard disk recorders can be divided into three categories according to their functions: traditional DVRs intelligently realize local storage; multimedia DVRs contain entertainment and advertising content; advanced integrated DVRs have various functions for products such as GPS, driving records, and wireless transmission.
However, behind the powerful features are also facing the pressure of monitoring technology. With the irreversible trend of network security and intelligence in the security industry, mobile DVRs will have some bottlenecks to break through despite their bright future.
Wide voltage stability

However, behind the powerful features are also facing the pressure of monitoring technology. With the irreversible trend of network security and intelligence in the security industry, mobile DVRs will have some bottlenecks to break through despite their bright future.
Wide voltage stability
As we all know, the vehicle will always encounter unstable voltage output during driving: input DC 12V or 24V voltage; but the traditional DVR needs a stable voltage value, otherwise it may lead to reduction of the reset and reduce the processing capacity of the computer. If this equipment is regarded as a power supply system, then the phone that the car transfers to the hard disk video recorder must be very constant voltage, otherwise it is very difficult to meet the normal monitoring demand. At present, most manufacturers use a wide voltage range, ranging from 8V to 36V only to adapt to changing environmental requirements. The
Wireless transmission and vibration
Regardless of mobile monitoring applications and areas, 3G transmission has become a major obstacle to its wireless transmission, and limited coverage and bandwidth are the biggest problems. The limitation of 3G is still watching real-time images. Whether it can transmit consecutively is still unknown.
Due to different road conditions, bumps are inevitable during driving. The vibration reduction technology becomes the most basic requirement for mobile hard disk recorders and hard disk drives. To solve the vibration problem, hardware and software should be based on mechanical integrated solutions. Reducing the vibration of the hard disk is the highest priority of the program because the track is most vulnerable to external pressure and will not be able to record inside the vehicle. At the beginning of the design, the manufacturer realized the hardware management of reading and writing at the same time and realized the switch between the SD card and the secure storage security.
