Battery life: I have changed the batteries once. It is several years old! I don't like to review something until I've had it for a while. I recently bought three more of these outdoor cameras.
Connectivity/range: I put one inside of a shelter box that I put outside to help a cat that has been coming around every night. I spotted him on another blink camera mounted to the eave of my garage. I set the motion sensor on, so if a different critter had gone into the box I could have scared it away making noise on the microphone. I have the hub plugged in to an outlet, near a window, inside my laundry room. It is a good 30 ft away from this cat shelter box. The camera is inside the box which is inside another box with a layer of insulation in between.
Video Clarity: It recorded the cat up close, and not blurry. It is pitch black inside that box. It is so clear, I'm hoping to be able to find the owner now! The eave camera that caught him in the first place, provided a little bit too blurry of a video to identify him. That is not a complaint! It's very far away and very dark! We live on an island, and there is very little ambient light here when the sun goes down!
Camera Noise: The camera must also be quiet! The cat did not flinch when that camera came on. I believe there's a little infrared dot light that comes on when recording, although I'm not sure about that. Anyway, I think you can turn that off in the settings. But, cats cannot see infrared light, I'm pretty sure. At least that's what I read on the internet so it must be true!
I highly recommend this camera, for any application. I also use one inside as a monitor for a different cat that I rescued. That's a story for a different day.
Mounts: There are various mounts that work to achieve bigger viewing angles, I have some of both. In all, I have 6 Blink cameras. 3 indoor and 3 outdoor. I would recommend any one of them!
