Button Camera 1080P Wearable Camera External Phone Camera for Android Smartphone(Type-C only) Indoor and Outdoor Use

I have to admit, this product is fantastic! I've tried many items, and this one is the best. It's undetectable, as the picture and video quality are excellent. I'm currently trying to figure out how to connect it to Wi-Fi and link it with another device. Any tips would be appreciated!

In short, its a great camera for the price. Audio is bad and I believe needs to be recorded on your phone, which will only be about 2ft from your camera as the cord is short .So if you put on shirt button area, the cord will be visible unless taped down and will lead to phone that likely will be in pants pocket. The camera will be at chest level and does not have a zoom out ability so you will be looking at whatever is chest level. This is a general, inexpensive hidden body cam meant for basic, non specific video/audio recording with poor angles and often times no faces or camera facing ground or sky as camera lens moves frequently in the button position - it is NOT as a nanny cam or hidden camera to record someone for law enforcement but again, decent for the price and the big issue is audio and the 2ft cord that must be connected to phone - also, my phone screen must be on for the recording to happen so you must have phone in pocket or hidden while screen is on.Android camera program is "USB Camera" - stupid name. Free version has ads and pro version is $5.50.Video quality can be downgraded to a comfortable 44.7mb/min at 1024x768 at 25fps, or the best is 128mb/min at 1920x1080 at 25fps. Quality can be downgraded further if desired. The 44mb/min was good for the project i used it for.

I have a question — I bought two devices. One of them works fine, but the other one shows a black screen when I plug the camera into my Android phone and connect it to the app. I’m not sure why this is happening. Who should I contact for help with this issue?is there any power button i need to open？

Works well. I have an old android phone I no longer use as my main phone that I was able to install the app on and when connecting the camera it works. Quality is OK, 1080p as advertised. It is very easy to conceal this with the button adapter lens cover. Though you will still have it tethered to your phone.
