Backup camera systems are slowly replacing simple rear view mirrors on cars. The popular rear view monitor system has a video camera at the rear of the vehicle and a monitor display for the driver to see clearly what is happening behind the vehicle. The enhanced vision and clarity that is offered is making them a popular choice with motorists worldwide.
While conceptually similar to non-vehicle CCTV cameras, there are some important modifications that have been made for vehicle use. Here are some factors to consider when choosing for your vehicle.
Automatic System Switching
Mirror Image Capability
Rear view monitor systems are capable of reversing everything in the rear view mirror to ensure you get the best view possible. Without this feature, we may be in danger of making wrong turns and accidents could be caused.
Camera, Cables and Connectors should be Weather Resistant
As the cameras are placed outside of the vehicle, they are exposed to dirt, rain, oil and snow. However, not all of them weather resistant so take care when choosing to ensure your model is weather resistant.
Vehicle Power Source
Remember to choose the right power source. Systems for semi tractor-trailers operate on 24 VDC and petrol and diesel engine cars on 12 VDC.
Monitor Type
These systems typically have LCD monitors ranging from 2.5 to 10 inches. You should have at least a five-inch screen for an adequate image. Some offer ‘style monitor’ that places the monitor near the driver and everything else around the back seat. TFT-LCD has the sharpest image. More information on TFT monitors can be found at tftcentral.co.uk.
Wired vs. Wireless
Wireless systems seem more convenient and pleasing to the eye but can suffer from interference if a vehicle with a similar system is nearby. A wired rear view monitor system is preferred for this reason.
Camera Features
A good quality camera will give you a clear image, so pay attention to the camera offered when choosing a system. Saving money is one thing but not at the expense of road safety.
CCD vs. CMOS Image Sensor
When comparing these two image sensors, CMOS is less expensive but image quality is much better in CCD.
Viewing Angle
The image sensor size and lens size are important to be of a good width and a 120-degree viewing angle is most suitable for the majority of vehicle types.
Infrared Night Vision
Infrared LEDs make the cameras easily recognizable, especially at night. The infrared LED range will limit the range of an infrared camera however, so you need to take that into account.
Audio Monitoring
A built in microphone in some cameras can be helpful but is not an essential consideration.
Rear View Monitoring System and GPS
Some GPS systems offer rear view camera options. Their priority is GPS though, so just make sure it has all the capabilities mentioned in the article.
Selecting a Rear View Monitoring System
Buy the system that has most of the mentioned features and also fits your budget. It’s important to save money but never at the expense of safety on the road. Better systems give a clear image of what is happening around your vehicle.
Rear view monitoring systems provide clear view of blind spots and ensure safety for all of us. It’s important to make the right decision.
