Sony CCD White Bracket Wireless Reverse / Rear View Camera with 7" monitor | DW21W

About this kit

This kit combines our latest built in digital wireless receiver 7" monitor.  The monitor comes with both a cigarette lighter plug and a hardwire kit, so you can choose which method to power the monitor from. This kit comes with one of our best selling cameras with the Sony 700TVL CCD image sensor and a transmitter box.  Simply power the sender box and this will power the camera.  If you wish to mount the camera more than 2ft away from the sender box then please select an extension cable in the options to do this.

Digital Wireless Vs Older Analogue Wireless

This wireless reversing camera kit uses digital wireless technology, which is significantly better than the older analogue wireless (which is somehow still about today).  Below is some information about the differences: 

• Wireless reversing camera systems are still carrying a bad reputation, due to the original analogue technology.  This older technology was so bad that we only stocked links that we marketed to cross the gap from the gas locker of a caravan, to a car boot.  
• The older analogue models were restricted in the UK and European market to just 10mW of power due to the "dirty" signals they produced.  This would have interrupted other networks had they allowed a stronger signal.  The new digital wireless technology uses 10 times this, transmitting at 100mW.
• The older analogue wireless used to provide plenty of static interference to the picture, and we would hear many stories of people driving along, only to suddenly see the view from someone's CCTV camera, and even the odd horse - whilst passing a horse box trailer.  The new digital wireless technology never has any static, or picture from elsewhere.  The transmitter and receiver pair together and use encryption, to ensure that the receiver ignores any other interference that is present.

Who Should use Wireless?

We recommend wireless for customers who have trailers (like caravans, Artics and horsebox trailers), they are also useful when an application is very difficult to run a cable front to back (heavily fitted out vans etc).  We wouldn't recommend wireless for cars, the main reason being the time saved by not feeding a cable around 2-3M through the interior is usually negated by the time taken making an extra power link for the transmitter.  Also with modern cars running CANBUS to the lights, if you come across a sensitive supply you may need to run a relay which is more cost and time.  For cars we recommend our premium cabled kits where the monitor provides power to the camera and just one cable needs to be run front to back and you don't have to attach in to the reverse light supply unless you wanted to activate the trigger.

Image Sensor for Camera

An image sensor is the part of the camera that detects and captures information to make an image, there are various sizes of sensor usually between 1/4" and 1/3" with the larger sensors able to capture more detail.  In the old days, you used to have to pick CCD for quality as CMOS wasn't as good, this has changed recently with some advancements in CMOS technology (there are varying quality levels of CMOS to confuse matters).  In this particular kit, we are using the Sony 1/3" CCD 700TVL image sensor inside the camera.  We consider this the joint best image sensor in terms of picture quality you can get on a reversing camera.

Anti-Corrosion Stainless Steel Camera Bracket

The camera has a stainless steel bracket, which is shown to last a very long time without corrosion unlike mild steel we have seen from most other retailers, which tends to rust in a matter of a few months.
