How the waterproof AHD ? reversing camera works
Share
Entry
Modern vehicles are equipped with advanced driver assistance systems, and one of them is a reversing camera. The waterproof AHD (Analog High Definition) camera allows for precise monitoring of the area behind the vehicle, even in difficult weather conditions. Thanks to the high image quality and durable construction, these cameras are a reliable tool for increasing road safety.
The History of Reversing Cameras
The first reversing systems appeared in the 1950s, but it wasn't until 2002 that reversing cameras began to be installed as standard in passenger cars. The first manufacturer to introduce this system on a large scale was Nissan, in the Primera model. Since then, reversing cameras have become standard in modern cars.
What is an AHD reversing camera?
AHD camera is a device that uses analog signal transmission technology in HD quality. Unlike standard analog cameras, AHD offers higher resolution and better image quality without the need for digital transmission systems.
Reversing Camera Resolution Comparison
| Technology | Resolution |
|---|---|
| Analog | 480p |
| AHD | 720p - 1080p |
| IP | 1080p-4K |
Features of the AHD Waterproof Reversing Camera
-
Waterproof: The camera has a sealed housing that is resistant to rain and dust.
-
High image quality: 720p or 1080p image resolution provides better visibility.
-
Night mode: IR illumination allows you to use the camera in the dark.
-
Wide viewing angle: An angle of 120° to 180° allows for full monitoring of the space behind the vehicle.
AHD Camera Installation
Installing an AHD camera is relatively simple, but requires basic technical knowledge. The installation process includes:
-
Selecting a suitable mounting location, e.g. above the license plate.
-
Connecting the cables to the power supply and monitor.
-
Mount the camera using screws or double-sided tape.
-
Testing system operation before full installation.
Benefits of using an AHD camera
-
Increased security: Reduces the risk of collisions when reversing.
-
Better visibility: Clear images in difficult lighting conditions.
-
Easier assembly: Can be installed in most vehicles.
-
Durability: Resistance to water and low temperatures.
Problems and ways to solve them
Common Problems
| Problem | Possible causes | Solution |
| Image interference | Poor cable connection | Checking and correcting connections |
| No image | Damaged camera | Replacing the device |
| Poor image quality | Dirt on the lens | Cleaning the camera |
Updates and new technologies
Modern rearview cameras are constantly being improved. The innovations introduced include:
-
Wireless connectivity: Eliminate cables with Wi-Fi transmission.
-
Integration with AI assistants: Obstacle recognition systems.
-
Better image processing algorithms: Improved quality in low light conditions.
Technical requirements
For the AHD camera to function properly, the following are required:
-
Monitor supporting AHD signal.
-
Power supply 12V.
-
Appropriate cabling ensuring stable data transfer.
Usage process
Using the AHD camera is intuitive. When you engage reverse gear, the image automatically appears on the screen, allowing you to safely reverse. Some systems offer additional guide lines to help you judge distances.
Image quality in AHD cameras
The image quality of AHD cameras is much better than that of standard analog cameras. The graph below shows the difference in resolution:
