nonda Zus Smart Backup Camera, Real Wireless Rear View Camera with 170 Degrees Wide Angle and Rechargeable Battery, Ip67 Waterproof, Easy Installation with No Wiring Or Drilling Needed, ZURCBKUAL-A

This is a review of the UK version of this product. I ordered from Nonda's own website and the backup camera was sent from Germany. The UK version comes with a black plastic number plate holder, with space to mount the camera at the bottom. A standard 520mm x 111mm number plate will fit in this holder. I had no problem connecting the camera to the Zus app, which takes you through the simple process step-by step, I have a Nokia 8.1 running Android 9. The package comes with a magnetic phone holder that clips into a standard car air vent too. To use the camera you press a button in the app and the camera is woken up via Bluetooth (I guess because Bluetooth uses very little power so allows the camera to enter a low power state while waiting to be woken up) the phone is then told to stream video via a WiFi connection to the camera. The image takes between 3 and 15 (!) seconds to appear so it's best to activate the camera before you need it i.e. when entering a car park rather than at the moment when you want to reverse, this isn't really a big problem. The image quality is fine in daylight and quite grainy at night, but it's still fine with your reversing lights on. There is a lag on the image update so you have to take that into account. The wide angle lens is useful when reversing out of spaces where visibility is poor. If the camera had less lag and connected in 3 seconds consistently rather than sometimes taking much longer I'd give it an extra star. This is an OK product and actually really the only option out there that's completely wireless.

On the face of it a good idea, however, the connection is clunky and slow - and very unreliable. It is so slow that by the time it has connected (if it connects at all) you have already reversed and gone on your way. One of the major problems is that it bis not a quick tap on an app... first you have to open the Zus app then go to the camera line and click connect. Then it connects via bluetooth and then provides a wifi stream from the camera (sometimes). More often than not it just says unable to connect.Charging is easy (a quick two security bolts and its off) and necessary as it spends so long trying to connect it runs down in about a week.I have finally got round to removing it from my car and I guess it will just sit in my garage until I throw it away at some point in the future.As much as I like the idea of a fully wireless rear camera I don't think I could ever recommend this as a viable reversing camera.

It was better than I expected. Camera work great on my cheap phone. Video very clear (Don't compare with phone) but it more than good enough for backup camera! Keep it!

Simply doesn’t work.

I bought this as part of an Indiegogo crowdfunder. The concept is fantastic but the execution is terrible. First unit went back to China after about 3 months as water got in to it and damaged the battery. Second unit has been fine.The biggest issue is connectivity. I am using the latest version of the app, and as far as I'm aware there are no updates for the camera. The app-camera communicate over both bluetoorh and wifi. guess the bluetooth is low-energy to make sure the devices are talking and to check whether the camera needs to turn on. This works pretty well. I have had a few connection issues but a restart of the app fixes that.The biggsest issue is when the camera turns on. It sets up its own wifi network specifically with your phone. It can take up to a minute for this to happen, which is annoying but you can plan for that. Once the image starts to come through is when I have real issues. I'll get a live feed for about 5 seconds, then it goes in to delay. At this point I tend to get a refresh of the image about once or twice a minute and generally several minutes behind current. I've left it running int he past on a 15 minute journey and it never catches up and by the time I've stopped its showing me an image from about 10 minutes previously. As a partking aid, it has proved to be useless. it may be the configuration of the app, my phone, the camera, I don't know, but the set up doesn't work for me.
