BOBLOV C18 wifi body worn camera is pretty cool. It’s a small camera that can record video, photos or audio and it comes with a clip so you can clip it on your front pocket, shirt or anything else that you want it on. You get first-person videos hands free and there is only one big button on the front of it for recording, so it's really easy to operate. It does have both a built-in rechargeable battery and memory, so all you have to do is charge it to use it. You should decide if you want to turn on loop recording first so it overwrites the oldest data or stops recording when full.
It also has a .66 inch screen built into it so you can see the different settings as this will shoot 1080p down to 480p and has WIFI to connect to your iPhone or uses OTG to connect to your Android device (if it has OTG) if you have the app installed. The app does control all the settings and allows you to view all the videos and photos you took with the camera.
With a 1200 mAh battery and 32 GB of memory, you can get up to 4 hours of video at 1080p if you don’t use the WIFI and does take about 2 hours to fully charge it.
