There are few decisions that are as irrevocable, as when you put the crosses in the equipment list of the purchase of the new car. But don’t worry, if you forget something.

Some shortcomings there may namely be made up. This applies, for example useful safety devices such as rear view camera, which can prove to be an advantage when it must be backed with a trailer or parked at the local grocery store in the ulvetimen.

It is no coincidence that the rear view cameras have become a natural part of the higher udstyrstrin of many new car models and can be bought from about 4000 to 5000 dollars for models in the mid-range. However, it is also possible to buy a rear view camera and the associated monitor to retrofit for rates that start from about 500 dollars plus fitting.

There is a big difference in both the technique and the ease of use as the fitting of the cameras, so here we will guide you through the jungle to the right purchase.

there are several things that are important to clarify before making the purchase. It stresses Henrik Fosgerau, who is the owner of specialkamera.dk – one of Denmark’s largest camera stores.

He is selling in a large extent to the professional trucking companies with vans and trucks, as well as to friluftsfolk with a great motorhome or perhaps a horse or boat trailer. But there are also private past. They typically have in common that they would like to have better view in daily life.

– The private, as the buyer, are most often elderly people, or people who for example have problems with turning the head. But it can also be the people who have bought such a big car, that they find out that it will be a good idea to get help with a camera, says Henrik Fosgerau.

You must among other things assess the size of the screen, and on the connection between the screen and the camera should be with cord, wireless analog or digital.

As a starting point you must go outside on the set with the wire and instead aim for a wireless connection and a screen, which is at least five inches. It can be a comprehensive work to pull a wire through the car, while the screen must be of a certain size, that you can orient yourself.

available in both analog and digital signal. The latter is more stable, but the camera and the transmitter fills also more. According to Henrik Fosgerau works the analog signal as well. Here can, however, be the risk that comes signalforstyrrelser from, for example, surveillance cameras, while the range is not as long as with the digital cameras.

Some companies advertise also with the infrared camera, but for ordinary car owners is it is not required. The cameras are very light sensitive and can ‘see’ reasonable by the vehicle’s reversing lamps, sounds from Henrik Fosgerau.

the camera Itself can typically be mounted on the nummerpladerammen. It must, however, have power to be downloaded from the baklyset. And here you have to be able to ally you with your workshop to have made things correctly. The wiring on newer cars can be very sensitive.

In certain cases it may also be necessary to drill a hole in the tailgate to pull the cord through, and in that case there should be one to two hours in the workshop. The mounting of the wires is typically in the 600 to 1000 dollars per hour.

Use your old screen

If you have an in-built screen in the car, or maybe a navigationsanlæg from Garmin lying, can both screens be hooked up to a camera.

It can be done from the 500 dollars plus the installation of the camera, if it has to be unoriginal. It may in some cases be significantly cheaper than a originalmontering, but an original camera, however, can be better adapted.

A new option on the market is a smartphone-based system. Here downloading an app to the signal from the camera and displays it on the screen. The system typically costs from 1700 kroner plus the installation of the camera. Here, however, you must be aware that the phone is blocked in the turn.

Even with so much electronics, it is ultimately you who is responsible. According to the Council for Safe Traffic, it is about to find out, and back in small movements. Bak like into a narrow parking space, so you run out with the snout at the front.

Talk with the mechanic

It can be challenging to build the electronics on the newer cars. Therefore, according to the bilteknisk editor at FDM, Søren W. Rasmussen, a good idea is to turn the mind with the scientific community, before you buy a rear view camera.

Bilistorganisationen experience, that sales of rear view cameras from FDM shop, especially for car owners, for example, running with large caravans or a horse and boat trailers.

– It can be hard to find a set which fits completely to your car. It is therefore a good idea to consult with her mechanic and get a total price, before you buy a set with rear-view camera, says Søren W. Rasmussen and adds:

– the Wires and the camera can not always completely adapted to the car’s design. Here, one may instead want to investigate what it costs to get retrofitted an original set of rear-view camera, or, perhaps, alternatively, the parking sensors, he says.
