Wireless Digital License Plate Backup Camera, HD 720P Car WiFi Rear View Reverse Camera Super Wide View Angle Waterproof, USB 5V Vehicles Cam for iPhone, iPad or Andriod Devices

The camera itself works quite well. My problem is that I can either a) leave the cell phone on 24/7; it won't have to spend time booting, and the camera will be visible in seconds, but the phone will run down if I don't drive the car daily; or b) I can turn the phone off when I leave the car, and it will take over a minute before I have the rear view.Perhaps the solution is to find a wire that's always live, even when the car is off, and tap into that. I imagine that it would take months for a cell phone to drain a car battery.I might have better luck using the cell phone that I talk on; I was just hoping to find uses for my older cell phones - obsolete but not broken.

I finally downloaded the app and use it to hook up to my camper. Velcro to SUV open back door and just plug into my phone.

This product and its software are useless! The first I purchased did not work at all and was exchanged for another. It was useless along with the software. It did not work with any reliabilty. When it did work, briefly, it would a present frozen image that was a mirrored. The software was unresponsive and useless. It was returned for a refund. I will not purchase it again and recommend you do not either.

This is the worst backup camera ever.The connection takes a while and the picture just freezes on the app after a while.I liked the usb connection, I wanted something like this as a magnetic mount without a battery, which should be simple to find but this is not it. Stay clear.

Very usefull

Don't waste your time or money. Could not get the picture load. Tried several apps and nothing worked. Piece of garage. Returned it the next day.

I do not recommend it . Not work well very slow . The application in iPhone is very bad .

Absolutely useless. Does not work at all. Maybe an Android thing, but this is being returned ASAP.
