XDV 4+

I’ve worked in IT for about 20 years(not a boomer. GenX). This took me longer than necessary to get working on my iPhone. Like the other reviewer, downloading the app was easy. Connecting to the WiFi was easy. However, the App could not connect to the camera.
Fix for iPhone only: within iPhone settings, scroll down to find the XDV App. In its settings, turn on Local Network. Done.
Other phones may have something similar. So, if you run into the app not finding your camera, look for that other setting. Good luck.
Once it is working, I recommend downloading any video to your phone, before trying to play it. The streaming takes longer to get the video ready to play, than it does to download, then play from the iPhone. Very short test video.

Aside from the App, you can connect to a PC(probably Mac too), via USB. Then, Power the camera on. Select USB Mode. This method, you can simply use it as a flash drive to get to your pics and videos.

1-2 stars for setup difficulty(lack of instructions really).
4 stars for ease of use and quality of video. Not too bad.
5 stars for the design. Accessories. And operating system on the device.

Amazing camera! I know I already wrote an review but here’s another. Okay first of all. All of you people out there writing bad reviews because your camera doesn't work, READ THE INSTRUCTIONS!! I mean come on?! you are voting this badly even though you don't know how to work it. Second thing, If you want a cheap GoPro that works great, buy this camera!! Such amazing quality for a sports camera! Is waterproof (with the case on) and portable. And finally, I would like to see you add a feature where if you connect the camera to the wifi, it will automatically use that camera for different apps. (That probably makes no sense but thats how i'm describing it lol.) Anyway, thank you for your time!!!

So I have had theCamPark camera for a while but never used it. Decided today was the day. Tried to use the QR icon in the book to download the app for WiFi. Icon failed, ball one.
In order for the camera to work with your phone, you have to join the camera WiFi. This removes what ever WiFi connection you might use else where. Strike one.
Installed a memory card into the camera. Tells me it needs to format before I can take photos or video. Strike two.
Decide to go buy another memory card, so I try to use the app. Get the error that it
Needs local authorization. I installed the app, what more does it need. Oh wait, I denied the location service!!! If it won’t run with that turned off... Strike Three, You’re Out!!
