Guide For Buying a Reverse Camera

Reverse Cameras is becoming more and more important safety aids for the more expensive or upper end vehicle brands. More and more vehicle makers are incorporating reverse cameras into their units primarily to prevent the increasing amount of accidents during reversing. Could You fit and use one, of course you can.

What is a reverse camera?
A Reverse Camera is a camera fitted to the rear of the car, RV, caravan, truck or even boat to name a few applications.

A monitor is placed in the car in front of the driver and is activated when the car is placed in reverse either from one of the reversing lights or the switch on the gearbox

The reverse camera as a safety aid!
The Reversing camera is a logical progression from parking sensors. Cameras allow the driver to monitor the rear bumper and beyond.

Most vehicles tested that do not have Car Rearview Camera have obvious reversing blind spots.Test results indicate that cars with reversing cameras can vastly improve rear visibility.

The fittingof a reverse camera kit
The Fitting of the camera is not all that difficult. But you should probably get it fitted by a professional as in most cases you must cut into the bodywork of the car(not always). The camera must also be placed in the right position as get maximum exposure at the rear of the vehicle

The monitor fits either on or in the dashboard. But the most popular fit over the existing rear view mirror with straps. The wiring is the most time consuming, although the newer kits are “Wireless”,you still have to connect to the power and reversing switch which is not that difficult.

Important points to take into account
Since it’s extremely unsafe for the driver to be required to switch the system on manually every time he or she wants to reverse, it’s important that the reverse camera system has the ability to switch on automatically

A reverse camera system should have the capability to produce a ‘mirror’ (or ‘reverse’) image through the camera or monitor.If a system has not listed this feature, then it probably does not have the feature

Cmos and ccd the fifld of view
The field of view provided by any camera is determined by a combination of image sensor size and lens. The larger the image sensor, the wider the field of view. However, a larger image sensor does not always guarantee. While a 90 degree field of view may be sufficient for some smaller vehicles, a 120 degree field is ideal.

You should always try and use a high quality CCD imager from a well known manufacturer. If the system you require doesn’t state that it utilizes a “CCD” image sensor, then it probably doesn’t.

Night vision
Always consider purchasing a reverse camera system that does include night vision illumination. The infrared illuminators should provide a minimum of 10 feet of illumination, and 20 to 30 feet or more of illumination is strongly recommended

Wired vs wireless systems
One important fact is that most of the wireless systems have fragile antennas on the camera and receiver that must be aimed directly at each other. Most have antennas that are easily broken during normal use.

I prefer a wired system for reliability. If you really require a wireless rear view system, then you will have to settle for a lower quality picture due to interference etc, always go for top quality in this regard.

Tips For Select Back Up Camera

Security camera surveillance system safety monitoring system is physical principles apply, microwave or optical fiber, coaxial cable, etc., in a closed circuit within the circulation speed of the video signal transmission, real-time image, a true reflection of the object to be monitored, and security cameras the integrity of the image from the camera system, display and recording system composition. At the same time, set the alarm systems and equipment available to legitimate intrusion alarm, place of birth model output alarm alarm host, trigger an alarm and video surveillance system records

Here are some tips to help you select which back up camera system and what type of model is right for your current needs.

A wired rear view system mainly consists of a monitor, rear view camera, Car Rearview Camera, cables, remote control and power plug that typically fits in your car lighter.

TFT LCD: As far as monitors go, a TFT LCD monitor is a popular choice. TFT LCD monitors come in a wide-array of sizes like 2.5″, 3.5″, 5″ and 7″. In addition, there are also 5.6″ and 6″. These two aren’t as popular as the other sizes, but you may find that the larger screens work best for you. A good way to gauge what monitor works best for you is to first think about where you’re going to use your monitor. Is it in your small or mid-sized sedan? Or perhaps it’s in your truck or work-van? If you have a RV you might find it beneficial to use a backup camera system when driving that. Cars can typically be okay using a 3.5″ monitor, or any of the smaller sized screens. These sizes work well for cars because they’re small and work well in your dashboard without being obtrusive. You could possibly go for a larger monitor, but keep in mind that it can obstruct your driving view and pose as a danger. For trucks and larger vehicles, a 5″ to 7″ monitor would work expertly. There are many 7″ TFT LCD rear view monitors out there today and they are a common size for trucks, vans and SUVs.

CRT: It’s black and white and also the volume has a wider range of volume. Because of its heightened sound capabilities, CRT monitors are often used in freight trucks and large passenger busses. In addition, because it doesn’t have the crystal clear image quality of the LCD monitors, it’s a little cheaper than the TFT monitors.

Cameras: There are two main types of chipset for cameras: CMOS and CCD. In terms of image quality, CCD is better than CMOS, and consequently they’re more expensive. However, CMOS technology has developed over the years and its image quality works adequately for regular passenger car usage. Night vision is essential when looking for a rearview backup system, so when choosing a camera, keep your eye peeled for an IR function. For cars, there are license plate cameras available and for trucks, shockproof cameras are available.

Another key thing to look out for when buying a backup camera system is the power input range of the camera. In many cases, you would be better off choosing a free power input between DC11~32V. This can protect your monitor from being burnt out by any unforeseen fluctuation in your car’s power source.

All in all, you’re doing yourself and other drivers, a huge favor by purchasing a backup camera system. As long as you are buying it from a reputable retailer with a knowledgeable and helpful sales staff, you’re sure to get the perfect purchase for your vehicle.
