How to select best Rearview Mirror Camera for your car
|8.3.2017||Posted by electronics51 under Auto-moto|
Rearview Mirror DVR technology is a fantastic safety feature in any car, so much so that by 2018 all new cars must be fitted with these units. From hooking up your trailer, reversing into a tight parking spot or just making sure your kid is not behind your car when you reverse, these units will make the job so easy. If you are in the market for a new rear view camera there are some pitfalls that will cause serious buyers remorse so this guide should make your decision much more informed and easier.
The biggest factor in choosing a rear view camera is how much can you see. So your biggest 5 factors are:
1. Automatic System Switching
Possibly the most important feature to look for when purchasing a rear view camera system, is that system’s ability to switch on automatically whenever the vehicle’s transmission is placed in reverse. This is accomplished by connecting a single wire to the vehicle’s backup light circuit, sending a signal to the rear view camera system, causing it to switch on without any action by the operator.Many so-called ‘rear view camera systems‘ don’t have this feature, and will require you to manually switch the system on every time you want to see behind you. The higher end systems will have this ability to switch on automatically, in addition to being turned on manually any time using the monitor’s front panel power button (or wireless remote control, if so equipped). Since it’s very inconvenient and extremely unsafe for the motor vehicle operator to be required to switch the system on manually every time he or she wants to back up, it’s imperative that you never purchase a rear view camera system without the ability to switch on automatically. If the system you’re considering doesn’t clearly list this feature, it almost certainly doesn’t have this feature. Never purchase a rear view camera system without this feature.
2. Field of View
The field of view of the camera is determined by a number of factors like the image sensor size, type and the lens focal length. Like a normal camera the bigger the sensor the better the quality of the picture, the better it performs in low light and the wider the field of view it can achieve. A 1/4” sensor can only deliver a 60 to 90 deg field of view while a 1/3” should deliver around 120deg.
90deg is the minimum field of view you should accept, but seeing there are so many units that perform better I would not purchase anything less than 120 deg. 1/3” image sensor and a 120 deg field of view should be your baseline. There are super wide-angle units of 180 and even 210 on the market. Sounds grea,t but these units create a fisheye lens effect and it is virtually impossible to use them to reverse. Imagine reversing by looking through the peephole in your front door, you are guaranteed to have an accident at some point.
3. Screen Size
No matter which rear view mirror camera system display you choose, it’s likely to be smaller than some of the standalone models just because the display has to fit inside the dimensions of the mirror. A smaller display makes it more difficult to see the details in the image which are important in the case of a back up camera display. Look for a monitor size in the mirror of at least 4.3 inches in order to get the best image possible.
4. Video Inputs
Some cameras come with multiple video inputs that can handle the inputs of both a car rear view camera and a car DVD player for instance. If that’s important to you, look for dual video inputs on any display you buy.
5. Bluetooth Hands-Free
Some displays come with additional options that can be very helpful including Bluetooth hands-free capability. Bluetooth hands-free model can be connected to a Bluetooth-capable smartphone so that you can use your phone without taking your hands off the wheel. It’s a great safety feature and one that can prevent you from getting a ticket in states where hands-free is required.
