New range of mobile digital video recorder is vital to fighting false insurance claims and deterring theft and vandalism.
False claims cost businesses millions of pounds, usually because of the lack of evidence.
But recorded footage from vehicle-mounted cameras will provide an accurate witness to help with investigations.
This also identifies potential hazards and operational problems, such as missed bins, operator safety issues and adverse driver behavior patterns.
Large fleet of vehicles can be protected at low cost with these durable digital video recorders.
The new range includes a hi-tech product to help fleet managers record using a live video feed and the option to download recorded footage to their mobile devices.
The range includes a durable, cost effective model and another that includes location tracking and speed and acceleration monitoring to motivate best driver practice.

Focus on Mobile DVR Systems
Uses of Mobile Security Systems
All of innovative surveillance cameras and security systems are designed to provide a cost effective means to protect industrial sites from unauthorized access, vandalism and theft. Most of these systems are 'standalone' solutions, and can operate and record footage without the need for additional equipment. When monitoring vehicles and other mobile property, however, it is not always practicable to install such a system, so often a solution is employed that utilizes a number of CCTV cameras connected to a mobile digital video recorder (MDVR) system.
Where Mobile Surveillance Systems are used in? Applications where mobile surveillance systems can be utilized include in: Buses Trucks Public transport Vessels Heavy machinery
Users can search video by date, time and event or filter by type of recording quickly and efficiently. A Smart Search function enables you to set specific regions of interest (ROI) in the field of view and search for relevant video within the ROI in order to efficiently review significant activities. The Snapshot Search extracts images at a defined interval to quickly locate events.
Important Points in Designing DVR System
Designing a DVR system that is appropriate for mobile use presents some challenges. Foremost, the system needs to be able to cope with the bumps and vibration of constant movement. Further, if employing a HDD to record footage, a sufficient backup system often needs to be put in place to ensure that the HDD does not fail under this constant movement. Another important consideration, and one that applies to DVR systems more generally, is the quality of footage the MDVR is capable of capturing. There are two factors that can affect the overall quality of surveillance footage. One is the quality of the security dvr recorder, while the other is the camera resolution.
There is no point in using a high quality DVR system with low resolution CCTV cameras, and by the same token, using high resolution cameras with a poor quality recorder is equally counter-productive.

Development Treads of Video Recorder
Rapid Development of Video Recorder
Video recorder gets increasingly wide applications, video coding technology develops rapidly and the features of product tend to be more diverse. The rapid development of embedded real-time operating system and the software is embedded in flash which cannot be modified with characteristics of simple and compact structure, small size and others and it pursues a more professional and practical mobile digital video recorder. With the matures of video and audio encoding technology, the constant improvement of the product features and application fields are continue to broadened, the market demand for embedded DVR is growing at high speed. And with the entrance of enterprises with a strong technical and financial strength, it is bound to further promote the development of embedded DVR market.
Current Situation of DVR
The number of company who has its own R & D capability on embedded DVR is rare. Technical threshold: the development of DSP, embedded real-time operating system and network development. Generally dvr manufacturer has not capabilities on low-rise development, while the application of foreign programs is limited by the original proposal resulting in the shortage of flexibility which is unable to meet the diverse needs of customers. And the other is capital threshold: the purchase of the development environment, the establishment of the development team, the investment of development capital and the shortage of developing talent. Furthermore, some are lack of network functions, and some network functions are not strong.
Routine Maintenance of DVR
First, Place the recorders in the cooling ventilation occasions with good air circulation and heat dissipation while it should not be placed in direct sunlight or near heating appliances. Because the life of electronic devices in recorders will be greatly reduced at high temperatures, or even damaged, recorder's shell vents should not be blocked, the cover must be removed when it is started. Second, the environment with damp or wet corrosive gas is taboo for the use of the DVR, moist environment causes inside metal parts corrosion, and even worse, it may block the machine transmission parts, or causes electronic device leakage, short circuit, and even electrical breakdown. Latest recorders with condensation protection device will automatically shut down when the interior is too wet. And do not make it work in a gas, smoke environment. Third, the case of DVR should be wiped by clean soft cloth. Recorders should stay away from the magnetic field, or it will interfere with its normal work, and the magnetization of internal parts. It is better to stay away from the speaker, induction cooker, magnet toy and electronic table.

An Overall Knowledge of Mobile DVR
Basics of SD Card Mobile DVR
The mobile DVR belongs to the traditional embedded DVR market segments, it is an emerging specialty products developed for vehicle applications as digital video and audio encoding technology. It uses the embedded processor and embedded operating system, and combines with the latest H.264 video and audio compression or decompression technology, GPS global positioning technology, 3G wireless communication technology, USB communication technology, advanced vehicle power management technology and GIS geographic information technology, it is suitable for all kinds of car models for 24-hour surveillance. Audio and video sync video, global positioning, wireless audio and video real-time transmission are available, at the same time, the host set aside a variety of interfaces, it can connect with the car display, IC card-board machine, signal priority control systems and passenger car statistical system devices. Nowadays, SD Card Mobile DVR are widely used in mobile transports such as public transport, long-distance passenger transport, tourist bus, logistics and freight forwarding, police enforcement vehicles, trains, subways, ships, aircraft and so on.
Storage Mode of Mobile DVR
At present, the mobile DVR has three storage means, they are hard disk, U disk and SD card. By comparison, reliability of U disk is higher. 1, U disk has no mechanical moving parts, low power consumption, you can use in the severe and harsh power environment. In these car, the ordinary SD card mobile DVR cannot work properly; 2, Convenient transcription data, the U disk can be directly plugged into the computer USB interface, you can playback video, save video and without hard disk connector and USB adapter, easier operation; 3, U disk interface design is suitable for repeated mating and more reliable than the SD card. SD card interface is the interface equipment, it is not suitable for regular plug and the damage rate is quite high.
Wide Application of Mobile DVR
So far, the video and audio codec algorithms of most mobile DVR manufacturers choose are: MPEG-2, MPEG-4, H.264, MJPEG, etc., among them, compression ratio of MPEG-2 and MJPEG is low, seldom use in usual time; while the H H.264 encoding algorithm has the characteristics of high video compression rate, low stream, wireless networks low bandwidth adaptability it is now the optional compression format direction of mobile DVR. Mobile DVR, with the increase degree of social recognition, the requirements of a variety of different mobile DVR levels also appear. With the constant improvement of its function, its application scope will become an increasingly widespread and growing role, it will not only used in the long-distance bus, but also will be widely used in common buses. mobile digital video recorder will play an important role for the civilized life in the society.
