This is a dual 12v or 24v monitor with a 7 inch colour TFT screen. It uses a high resolution digital LCD panel which gives a much better picture than standard panels especially when used with CCD cameras. The resolution is 800 x RGB x 480 points (800 x 480 pixels). It is unusual to find this design with the 4 pin connectors to the cameras. It can take up to 2 cameras and provides them with power via the 4 core cable. The power board to the monitor is external which is a great advantage as it is cheap and easy to replace if there are any problems. It is very easy to make a system with this monitor as all you need is the camera, 4 pin cable and monitor. It simply plugs together and all runs off the monitor power supply.
This photograph shows the monitor, wiring and remote control.
When the monitor is not displaying an image it acts as a conventional mirror. The image however is similar to if you have a normal interior mirror on dip. These monitors are often used as an always on rear view mirror especially when matched to a CCD camera.
The image above shows a typical view using this monitor with a reversing camera in the down position. This is an actual photograph of the screen displaying a picture from a CAM222.
This image shows the view from a CCD camera in the up position. When used with a quality CCD camera it gives an excellent picture with a sharp image. We are moving more onto the Sony CCD sensor and this monitor suits it very well giving life like colours. The Sharp sensor can still be a little pale on greens in the sun.
The image above shows how thin the monitor is.
We have this monitor matched to a number of our CCD reversing cameras. These kits represent good value for money as they are often as cheap as RCA based ones if you add in the extra cable costs in making them continuously power the camera. If you have a 12v vehicle and want to run it off a cigarette lighter plug then we can organise this for a small charge.
The reflective nature of the front of the mirror monitors can give issues in cars especially. We have had some success in cutting down the reflection problem by using Matte ipad screen protectors. Below are some photographs showing the result with a "cheap and cheerful" Matte protector bought off ebay. The air bubbles visible are down to taking the protector on and off during taking the photographs. They are not normally there if you apply the protector carefully.
This one shows the reflections on a normal screen
This one has the MATTE protector on. By right clicking on these photographs you can get the full sized version.
Again this one is without the screen protector.

With these photographs we have tried to match the camera angles between the two pairs of pictures to give a true comparison. Our opinion is it reduces the amount of reflection you get in the monitor. By altering the angle of the monitor you can also get it in a position where reflections minimised. Both sets of picture were taken in a car. With the screen protector you would use the monitor as an always on rear view.
