Please stay with me as we delve into the details. I specialize in tech reviews. In general, these license plate cameras can be a great buy, yet all brands in this price range face reliability challenges. This means great customer service and ease of replacement are essentials.WHICH eRAPTA? ERT11 VS. ERT01:First, be sure you have received the latest design with the all metal bracket. If yes, both are rated at IP69 to keep the water out! Both are considered high res at 1280 x 720 pixels. However, the fact they use standard RCA connectors makes this claim one not to rely on. In real world use, the eRapta’s typically yield a very impressive and sharp image, with quite decent color fidelity, too. Both are also related down to .1 LUX. A lower number is better—meaning they resolve low light well.Of these two, I suggest spending just a little more for the ERT11 without lights. Cameras like these rely on your tail lights plus their LUX rating. Ask yourself, how many built in car camera have mini LED lights surrounding them? Answer: None. No mini LEDs means one less thing to go wrong and a few users have complained about the ERT01 lights getting stuck in the on position. Subtle is best so after auditioning both, I went with the ERT11.WHAT ABOUT BOYO?The Boyo’s advantage lies in its superior bracket. Many factory cameras such as those on our Audi’s and Honda’s rely on a 45 degree angle. Boyo makes it easy to swivel the camera on the bracket to get the angle right. These allows for more accurate guidelines placement, too. On the downside, its resolution is 600TVL which actually means 720 x 480. Is this a disadvantage vs. eRapta? Yes and no. If you have purchased a high-end digital media receiver with a true high res screen, go with eRapta for sure. However, most screens like my Pioneer resolve about 800 x 400. They do not upsample images. Thus, when comparing eRapta to Boyo, resolution is not a strong determinant of image quality for most users.Most importantly, the Boyo is not sealed as well as the latest eRapta design. This means it is much more likely to get water inside. Thus, after evaluating both, despite the challenges with eRapta’s less versatile bracket, it’s the clear choice for me.WHAT ABOUT eRAPTA’S 149 DEGREE ANGLE VS. 170 FOR BOYA?Speaking from the perspective of a professional photographer, I would much rather have a camera slightly less wide at 149 degrees. The distortion is less and the view is still very wide. The wider the angle, the more far away that people behind you will appear in a parking lot. I can see a small child better with as a slightly tighter field of view.HOW TO ADJUST THAT DARN FRUSTRATING eRAPTA BRACKET?Although I am a huge fan of the ERT11, the only way to change the angle is by bending the bracket. Thirty-five degrees is the limit. Why is this an issue? If you don’t cut the green wire and decide to use the built in guidelines, for many cars this will leave the lines floating in space. Using two pairs of pliers, including one needle nose, I was able to bend the bracket out to get the angle much closer to 45 degrees. I also placed a small triangular shaped binder clip behind the top of the license plate to make the top just out a bit farther. You’ll see in my photos that the Honda CRV built in 45-degree angle now closely matches how I customized the eRapta. With the license plate screwed in tightly, these subtle angle changes do not show—the camera does not appear jut out more than before the bracket was bent.In any case, I strongly suggest that the good folks at eRapta go back to an adjustable bracket.WHAT ABOUT CUSTOMER SERVICE?As others have noted, utterly superb at eRAPTA. Commendable! I’ve had great communications with rapid replies. Although I have not tried to contact Boyo’s California office, I have read that others have been frustrated trying to reach them.WHAT IF THE CAMERA STOPS WORKING?Happily, eRAPTA gives a lifetime warranty but that does not mean it won’t be a pain replacing the camera. To ease the pain, I suggest having two on hand when you do the install. If one is bad, the other will likely be fine.Regarding wiring, most cameras of this type now have standard four pin connectors near the back of the camera. Try to do your install with an easy way to reach inside to grab the connector and pull it out should you need to change out the camera. Fortunately, it is highly unlikely you will need to redo the wiring all the way to the head unit.CONCLUSION:Hope this too long review has been of some small help. My impression is that eRatpa is always trying to improve its cameras and that’s admirable. Time for a more flexible bracket design but otherwise highly recommended.
