Recently, both of my neighbors' cars have been broken into and they stole everything they could in their cars, including chump changes, to fishing gears, sunglasses, etc... It's getting pretty ridiculous since the cops couldn't do anything. My front door and front yard camera caught them in the act, but it was way too far to see anything clearly or get a good read of the thieves' license plate... Thus, the reason I got this camera set. Both cameras have built-in battery and it last pretty long on a full charge. I have them up for almost a month, and battery is at around 85% right now. It's very small, very compact and white so they blend in well in my tree (where I attached these cameras on the tree trunk near my front gate, so I can have better video footage of the street and side walk in front of my house). I also like this setup with a central hub, because the captured videos and photos are stored on the micro SD card on the hub (which is sitting inside my house), in case thieves spot the cameras and trying to steal the camera, I can still have the footage to give to authority or insurance claims. I have the central hub sitting inside my house, which is about 100 feet away from the cameras, and the signal quality is at around 60%, which is pretty stable to ensure no losses in captured video/photo transferring. The phone app also notifies me anytime it detects a motion and send me a snapshot when motion was detected. It works very well so far. Hopefully, next time something happens in front of my house, I can get a clearer footage to provide to authority.
