This matches our heavy duty AHD dash monitor with our AHD twin lens camera. AHD offers higher resolution images and better night vision. The monitors use a high brightness 1024 x 600 panel with wide viewing angles. The system is for use both reversing and for continuous rear view. It has a trigger wire which if connected to the reversing light will bring up the reversing camera automatically. It should be noted that AHD systems switch slower than the standard CVBS ones. The monitor will accept both CVBS and AHD cameras.
The optional bracket is useful if your dash has curves that prevent the use of the U-shaped one supplied.
The lighter plug is useful in testing and setting up the system.
The hard wire fuse tap is one way of obtaining power for the system without cutting wires.
The following pictures show screen shots of this system in various situations. We use a mobile phone for these pictures as they seem to offer the best results. One problem we come across is you get "interefernce patterns" on the photograph that are not there on the actual monitor. Also the night views tend to be a little more blurred than the actually are. The results though will give an impression of what you will see.

This view is taken using the wide angled camera facing down for reversing. It gives a view behind extending about 11 feet and a width extending at least 2 foot either side the width of the van. This is with a camera mounted about 7.5 feet above the ground. One thing that stands out is the brightness of the monitor compared to earlier versions. In the past the reflectivity of the glass was often an issue, but it is much less of a problem with these.
Most of the time you will be using the narrow angled view to act as a rear view mirror. This is where the brightness of this version of the monitor will be of greatest use. The narrow angled camera will give an image very close to what you would expect on a interior mirror. Wider angled cameras tend to make cars look much further away and more difficult to judge distance.,
This image is taken at night in an area of total darkeness. The vehicle lights are on and it gives a good view of the road behind the vehicle.
Lastly this is a photograph of what you can see in the narrow angled lens in an area of total darkness. It represents the worst conditions the camera is likely to experience. Normally moon light or street lighting will allow more to be seen.
