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.
