1. Long-distance buses have complicated road conditions, faster speeds, and longer bodywork. It is advisable to install two or more dome cameras to monitor and record the doors and cars. If necessary, they can also be used behind and in the car. Baggage extraction port for surveillance video.
2. The bus population is congested 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.
3. Equipped with vehicle-mounted hard disk recorders on *, fire-fighting, and *enforcement vehicles. This has been very common in many developed countries abroad and is currently emerging in China. 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.
4. Other special vehicles such as postal vehicles, armored vehicles, hospital ambulances, school student shuttle buses, logistics delivery vehicles, customs supervision vehicles and dangerous goods transport vehicles, etc. can be installed according to the monitoring needs of 1-4 cameras, infrared Waterproof or telephoto zoom.
5. Car DVR It is recommended to install the driver's seat behind or on the luggage rack, the installation should pay attention to the following points: a, car DVR to be installed horizontally, from the car ground more than 20CM, conditions must be added 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.
6. 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 positive must pick 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. However, 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 microphones. It is not allowed to connect other electrical equipment.
8. In order to facilitate the timely and efficient management of the management, it is recommended that the company’s own company purchase n+1 car DVRs, which use “n†as the planned number of vehicles to install, “1†as the company’s video data for playing each car. Can be used as an office environment monitor.
