If you are a traffic management department, a public security department or a long-distance passenger transport company, a bus transportation company, or a private company bus manager and a logistics company leader, do you have more or less such annoyance that the flight attendants will not collect passengers halfway? For ticket or fake tickets, the passenger transportation company loses up to 3-5 thousand yuan per month per vehicle ticket; bus driver thief reaches into the coin acceptor; Nanjing bus passengers evade nearly 300,000 for one year; Foshan driver drinks and picks up; Liuzhou Drivers were repeatedly beaten up; Urumqi drivers reminded passengers to be retaliated against by thieves. The problems of these public transport systems have always been the focus of management departments and the most difficult problems to solve. Whether it is a passenger transport company and bus group, or a bus or bus driver; whether it is a traffic police department or a local government. Various methods have been adopted for various crimes such as corruption and looting on passenger transport and public transport vehicles. For example, Jinhua Public Transport has cracked down on “black handsâ€; Shenzhen police have taken various measures to improve public security; public transport companies in Liuzhou have equipped themselves with countermeasures.扒 Youth Volunteers; Taiyuan Bus “Smile Service†is famous both from the north to the south. However, these various measures have not solved the fundamental problems and are still very vexing. Citing the person in charge of the Shenzhen Traffic Public Security Bureau, he said: “Because the robberies on vehicles are action cases, the passengers can get up and down, and they can hardly find them after the incident. The witnesses often have difficulty in identifying evidence, arresting difficulties, and concluding difficulties.
With the development of mobile security multimedia technology and automotive electronics technology, the application of on-vehicle digital hard disk recorders: such as Kunming bus installation of "small TV" human service to expand the market; Qingdao public transport caused a technological storm; most Liuzhou buses will be installed "telescope" Implementation of real-time monitoring and operation; science and technology make Shanghai public transit “smartâ€; Beijing public transport will install “black boxâ€, Shenzhen bus equipped with four-channel car hard disk recorders, since then can be real-time and comprehensively present the most intuitive video and audio information in front of us, become public transport The powerful technical assistants of the management department provide scientific and authoritative basis for the traffic management department to accurately understand the causes of traffic accidents and the just handling of traffic accidents. At the same time, it also allows the legitimate income of enterprises to be effectively protected. Carry out warnings and exposing violations and crimes that occur in and around automobiles to ensure that our property and personal safety are fully protected. To play a positive and important role in building a more harmonious society.
The functions of on-board DVR products on the market are more and more perfect, but the quality and practicality are not satisfactory, and after-sales service and technical support are also uneven. Shenzhen Xideway Technology Development Co., Ltd. is a high-tech enterprise specializing in R&D and production of professional car DVRs. According to the actual needs of different customer groups, the company develops and manufactures a series of car security electronic products for high-performance automotive operating environment. Reliable seismic performance and automotive environment adaptability, while adding the appropriate external devices can have a wealth of value-added features such as GPS, GPRS, black box (vehicle speed, speed superposition) license plate and travel line recording, can provide perfect for a variety of occasions s solution.
On-board actual installation plan and precautions Introduction I. Long-distance buses have complex road conditions, fast speeds, and long special features. It is advisable to install two or more dome cameras to monitor and record the doors and vehicles, if necessary. You can also monitor videos in the back of the car and baggage claim.
Second, bus personnel are crowded and the interior environment is relatively poor. Therefore, on-vehicle DVRs are required to have higher performance in terms of seismic resistance and temperature adaptation. In an air-conditioned bus, the temperature in the south summer car can reach about 50 degrees, and the temperature in the winter in the north can reach -20 degrees or even lower. Under such circumstances, if the car DVR does not have good characteristics, it is difficult to achieve. This requirement. In a car that does not have good earthquake resistance, seismic shocks are also not possible with ordinary hard disk video recorders. To make sure that there are no blind spots and dead spots, it is best to install four cameras.
Third, in the public security, fire, urban management of law enforcement vehicles equipped with vehicle hard disk video recorders, which in many foreign countries has been very common in the country has now gradually risen. Car DVRs can record the entire process of enforcement by law enforcement officers as evidence of enforcement by law enforcement officers. They can also supervise the enforcement process of law enforcement officers and improve the enforcement level of law enforcement officers. The DVRs of law enforcement vehicles are generally equipped with LCD screens and PTZ control interfaces. Law enforcement officers can control the camera's camera position and zoom parameters through the control keys so that DVRs can record information on the external conditions of vehicles at different distances and different distances. in.
Fourth, other such as the postal car; armored car; hospital ambulance; school student shuttle bus; logistics delivery vehicles; customs supervision vehicles and dangerous goods transport vehicles and other special vehicles can be installed according to monitoring needs 1-4 cameras, infrared Waterproof or telephoto zoom.
V. Car DVR It is recommended to install the driver's seat behind or on the luggage rack, and pay attention to the following points when installing: a. Car DVR should be installed horizontally, 20cm above the ground of the car, and conditions must be added to the protection box; b. Car DVR must be firmly installed; c, car DVR can not be installed in the vicinity of the engine (too hot) or can not heat the place, the machine must be maintained at least 15-20CM spacing around to ensure ventilation and cooling; d, due to the need for ventilation The design is not closed, so pay attention to waterproof.
Sixth, car DVR power supply for wide voltage input DC to DC switching power supply, suitable for 12V and 24V cars, input power between 60-100 watts, the required access wire diameter is not less than 2.5 square millimeters, the power cord must be connected positive On the positive side of the battery, connect a 10A fuse in series near the battery. The negative pole can be connected to the vehicle body, but the grounding resistance must be less than 0.5 ohms. The machine output camera power cord can use 1.5 square millimeter GB double-row insulated sheathed cable, and the camera video cable can use more than 96 series copper 75-4 coaxial cable. For the exposed metal interface must be wrapped with tape to avoid short circuit.
7. The maximum output power of the power supply is 60 watts, which supports the power supply of the machine itself and up to four cameras and pickups. It is not allowed to connect other electrical equipment.
8. In order to facilitate the timely and efficient management of the management team, it is recommended that the company’s own company purchase N+1 car DVRs. It uses “N†as the planned number of vehicles to be installed. “1†is used by the company to play video data of each car. It can also be used as Office environment monitoring.
