The camera's field-of-view is broad, thanks to its 110-degree wide-angle lens, but is ultimately determined by placement. Drivers will want to experiment with whether the upper or lower license plate mounting bolts will yield the best results for their particular vehicle.
Because of the ACA250's extremely easy installation, just two screws and a wire, we were concerned that the easily accessible camera could be easily stolen by a determined thief with a screwdriver. We'd have liked to see the mounting bolts feature a unique key, or at least a hex socket and key, instead of the ubiquitous Phillips tipped screwdriver. This would add an extra complication to the already dead-simple installation and require that the owner not lose the key, but it would give us better peace of mind when parking at a shopping center or otherwise outside of a locked garage.
Usage of the ACA250 backup camera couldn't be easier. Simply select Reverse and it does its thing. The monitor is always on and always looking for a signal from the camera, which--as stated earlier--is only active when it gets power from a reverse light. The signal from the reverse camera is clear and, under most situations, devoid of interference. Of course, no reverse camera is meant to replace the vehicle's mirrors and common sense, so be sure that you look before backing up.
When not in use, however, the system's simplicity proves once again to be a gift and a curse, and its rough edges make themselves present. Because of the always-on nature of the system, when the camera is shut down, the monitor is still searching for signals. At best, this means you get a constants stream of flickers, flashes, and static on the tiny screen. This can be particularly distracting while driving at night, when the flickers stand out in an otherwise dark cabin. At worst, the monitor will pick up wireless transmissions from other sources, such as security cameras or, on rare occasions, 2.4 GHz wireless television transmitters.
While the rogue signals were slightly annoying when we were only picking up images of local businesses, we could see this becoming a downright awkward privacy issue if, for example, your neighbor's house is equipped with a widely available wireless security camera system.
Interference is more prevalent in heavily populated urban areas, so suburbanites and rural users will experience less static and flickers. Some drivers will be able to ignore the screen's activity and benefit from the added safety provided by the presence of a backup camera, but for more easily distracted drivers, the constant onscreen activity could represent a compromise of overall vehicle safety.
All things considered, for owners of large vehicles with poor rearward visibility the addition of a backup camera can greatly increase the safety for the driver and those around the vehicle. The Audiovox ACA250 wireless rearview camera system is an excellent and low cost way to add that extra safety with an afternoon of wrenching.
The Audiovox ACA250 wireless rearview camera system's simplicity makes installation and operation a breeze, resulting in high marks for design. Of course, the simplicity of the system could also be viewed as a weakness when considering things like theft deterrence, but we didn't count that against the design score. However, we do recommend that owners take the extra step of visiting a hardware store for more secure hex key screws.
The ease of use and the inclusion of infrared night vision also resulted in high scores for features and performance. We did, however, penalize the ACA250's performance score because of the distracting static and flickering of the monitor when the system is not in use. A better designed system would be less intrusive when not in operation and certainly wouldn't pick up signals from other devices.
However, your mileage may vary depending on the number of 2.4 GHz wireless devices in your area.
