CCTV camera Embedded
First, what is a board camera? It’s just a small-size integrated CCTV camera in a means of transport. It therefore fits in several areas.
Right now, this include board cameras for cars that bloom on the market.Attached to the windshield or inside the cabin, they film the road, and serve as evidence in case of accidents.
The board cameras, however, are not confined to cars, there are the many other means of transport, such as trains, buses and the underground trains or RER. In most cases, they are designed to improve safety on public transport.
They know how to be discreet, they are often found in encadrure scrolling panels to bus or ceiling of a train train. Their handy exposure in these very places fréqeuntés however causes degradation, their external protections are therefore type vandal to counter is type of scam.
The technology of CCTV cameras to advanced much in recent years, and thanks to her, it is now possible to have several operations means for the board cameras.
Indeed there are the technologies used for fixed cameras. Ie a bus can also be equipped with IP cameras than analog cameras .
For more information on the different camera technologies, visit the dedicated guides!
Cameras in public transport
The bus is equipped with several CCTV cameras spread to cover a maximum area.
These cameras are connected to a recorder that keeps pictures shot by storing them on one or more hard drives.
Then the recorder broadcast its content to multiple devices:
- Amonitor, allowing live view inside the bus.
- A3G transmitter that sends the video stream to the control center.
The recorder with its large storage capacity allows you to store images for several weeks, the new records replacing the old ones.
With the 3G transmitter, it is possible to view images in real time from a remote bus station. This feature increases the security of public transport in urban areas. It allows to initiate emergency in case of problems very quickly.
This principle applies CCTV for buses but also for other means of public transport, such as trains, subway or tram.
However it requires a complete, technical installation and does not adapt well to the cars.
Special models for cars
The type of CCTV cameras presented above is particularly relevant to large vehicles, but much less for smaller. A car, more compact has less space and rarely has room for recorder, transmitter, much less a monitor!
In addition, CCTV needs are not the same, only one driver will try to monitor what is happening on the road and not in his vehicle. So there are board cameras specially designed for cars.
These are much more compact, and generally hang inside the cabin, the lens pointed on the road. With an SD card or an integrated hard drive camera can record it fillme. The storage time is much lower, since only a few hours to reach the maximum capacity of the storage space.
However, some cameras offer different modes of records:
- Classic: enregsitrement continuously
- Custom: Set your camera to suit your needs
- Parking: Recording activates when motion detection
- Evennementiel: A shock sensor starts recording. The sensitivity thereof can be adjusted.
The video stream recording method is very dependent on the situation of installation of the CCTV camera.
In vehicles of large size where space is not lacking, it is possible to have asimilar recording system to that used in conventional infrasctructure. We thus have a recorder ( digital or analog depending on the technology used cameras) connected to hard drives that are responsible to keep the images.
However in the most compact vehicles, it is necessary to use alternatives. According to the need for storage, it is possible to use SD cards or hard drives connected directly to the camera. It is unfortunately not possible to manipulate the image as it could be done via a recorder.
If the record can cause problems depending on the situation, it is néamoins possible to view the video stream from a camera remotely with a smartphone or laptop.
Advantages and disadvantages
|Serve black box accident||complicated video storage|
|Vehicle Surveillance in case of abscence||Low autonomy compact cameras|
|plant similar to a traditional system|
|Vehicle break-in warning system|
What forms for Embedded Camera
There are many forms of on-board cameras. So they can easily adapt to the environment in which they are provided.
We find the flagship camera video surveillance: the mini-dome which is small, is easy to install and offers a wide viewing angle. It is easily equipable an anti-vandal protection, making it particularly resistant.
