A solution to change 180degree HD1080P the vehicle video surveillance that cannot be achieved by the traditional single camera-a dual-lens all-in-one camera with no blind spots
With the development of social urbanization, there are more and more vehicles driving on the road every day, and traffic accidents are staged every day. Therefore, the on-board video surveillance system has become today's commercial vehicles to protect themselves and protect the safety of other road participants. Essential system required. Used to collect evidence as a legal basis.
The vehicle video surveillance system mainly includes:
SD card car video recorder: mainly use SD card to store video data, usually at 720P and below resolution, short video storage time and short working time. Mainly used for ordinary small vehicles and short-distance vehicles in cities. As shown in the figure:
Mobile Vehicle DVR: The storage medium mainly adopts HDD and SSD. For manufacturers with technical strength, it can be compatible with the three storage media of SD card, SSD and HDD at the same time. Supports 1080P and lower resolutions, characterized by long storage time, and supports up to 2TB and above. The technical support performance of each manufacturer is different. Suitable for all kinds of vehicles.
2) Vehicle camera/Car camera (720P camera, 1080P camera)
According to the installation position, it can be divided into front-view camera, rear-view camera and side camera
According to the resolution, it can be divided into: 720P car camera and 1080P car camera, and there are worse resolutions.
According to the chip can be divided into: CCD and CMOS
According to the transmission method, it can be divided into coaxial transmission cameras and IP network cameras. When MDVR hardware resources are insufficient, IP cameras will be selected, and the pressure of insufficient MDVR resources can be reduced through IP cameras to achieve the best results. Otherwise, a coaxial camera will be used
3) Vehicle monitor
According to the size can be divided into: 7 inches and 9 inches and 10.1 inches as shown in the figure:
7 inches is the current mainstream, because for installation on vehicles, the purpose is to provide drivers with safe driving assistance
According to the resolution can be divided into: 800*480 and 1024*600
According to the connection method: AV connector, BNC connector, aviation connector, VGA connector
As shown in the figure:
4) Extended part:
1. Pickups, used for sound collection, can also be called recording, as shown in the figure
2. Speaker mic, used for remote real-time intercom, real-time communication between driver and server background staff. As shown in the figure:
3. Infrared remote control extension connector, extended when the MDVR host installation position is not conducive to normal operation. As shown
4. Emergency button. It is used for outgoing calls or reporting to the background in emergency situations. As shown in the figure:
1. PTZ and other equipment.
The above is a complete set of vehicle video surveillance system.
The difference between ordinary car camera and dual-lens camera:
The single-lens camera mainly monitors a certain surface according to a fixed angle,
Ordinary Vehicle camera/car camera angle: 110°120°140°150°170°180°Choose different viewing angles according to the actual application.
The effect is as follows:
Dual-lens Vehicle camera angle: 110°+180°, 120°+180°, 180°+180°At present, we mainly use 180°+180° and 120°+180°
The advantage of this is that two different areas can be monitored at the same time, and they can complement each other. The blind spot of monitoring is not avoided, and the viewing angle can be adjusted at will. Easy to install, it is mainly used for the monitoring or side view of the driving direction of the truck and the cab, and can also be used for the monitoring of the driving direction of the passenger car and the cabin and the driver. The effect is shown in the figure
As a dual-lens camera that can be adjusted up, down, left, and right, plus a 180° viewing angle, it is very easy to install and debug. Of course, the installation position and installation angle of view of different models will be different, but the final effect is the same. . For traditional ordinary cameras, if the driver and driving direction can be monitored at the same time, two cameras in different directions can be installed to achieve this. However, there are still great differences in the monitoring effect and the monitoring range.
The difference between a dual-lens integrated car camera and a standard car camera:
The monitoring range is larger,
Easy to install
Easy to adjust
The standard vehicle-mounted camera is installed in a fixed direction, and needs to be wired separately and fixed separately, and the scope of adjustment is also very small.
This is why we have developed a brand new dual-lens camera, which makes up for the complementary blind spots that the previous standard car cameras could not do. It is easy to install and easy to adjust. Save installation time.
Comparison of effects between traditional Vehicle camera and dual-lens camera
HD video effects are the current mainstream market demand. HD picture quality can provide clear video evidence after an accident. Of course, this requires more storage space, faster reading and writing speed, and more high-definition cameras. . These factors are complementary to each other, so when you choose an HD1080P camera, you need to consider using HDD or SSD as the first item of storage media. Thank you for your support of this article, and hope to help you better choose a car surveillance camera system that is worth your own.
