"Nice product though lacking some features."3.0 starson by eyepoker
Pros: The big plus is the infrared illuminators which will help greatly when backing up or parallel parking but like must illuminators they are only effective for a short distance. Granted, they shouod suffice for most applications.
Cons: A little bit of a fish-eye effect, but IMO thats not too distracting. The biggest con is the lack of controls on the LCD itself. On the VR3 Power, Brightness and screen rotation are available.
Summary: For a simple plug and play seems like a good enough value. However having owned a VR3 I now have my personal set criteria to go by. My VR3 only lasted one summer - the road salt from the following winter ruined the plastic lense and i also had condensation appear within the camera itself. For these two reasons I might be tempted to purchase more expensive units - I'm on the look-out for a glass outer camera lens and at least some mention of superior water-tightness.
Installation for all products like this one are the same. Wire to the reverse light. However, if you are like me you don't need a back-up camera only for backing up, but for day-to-day driving as well. I drive an H3 Hummer and small to medium-sized cars are all but invisibe behind me. At night, the auto tinting of the rear-view mirror removes the tell-tale glow of headlights so this inability to easily see what is following me applies to both day and night. The solution: wire not to the reverse lights but to the license plate light. Wiring in this fashion turns the camera on automatically at night for all-night-use and I can turn the camera on during the day by turning on my parking lights. This method gives my round-the-clock visibility behind my vehicle.
My VR3 functioned better in the country/highway than within the city where it had its share of flickering though I never encountered a stray tv or security camera image. I suppose interference is the nature of these types of wireless devices.
The big Plus for the VR3 is the brightness control. The daytime picture is much different than at night. At night I knew to click the brightness control a couple of times to get a better picture. As the Audiovox ACA250 product lacks a brightness control and the infrared illumintors have only a short effective range you won't get all the details of the road behind you while you drive. Granted, you are really looking for headlights/minimal visual information if you use the camera system like I do. Generaly speaking its purpose is merely for backing up in tight spaces and thats where the illuminators will do their work and where i suppose a brightness control will not be needed.
With those points in mind I'm sure that the Audiovox ACA250 will do the job that it is designed for. If you think you would like additional features they are in fact available in similarly priced units. Power, brightness, rotate screen (allowing for many other mounting alternatives) are at least available on some competing products.
All in all these products are a great idea. I'm currently researching what will be the replacement for my now useless VR3. (again, killed by moisture/road salt)
