We installed "Blink" security cameras about 2.5 years ago, all outside at our Nags Head home. We're between the highways and get plenty of salty wind. They have held up very well and do exactly what we need. I've got 5 of them, all placed to capture doorways, outdoor stairs and similar, including under the house in the carport area. They use AA lithium batteries, and I just replaced the batteries for the first time since installation, and only in the one camera that gets the most use.
The camera that is furthest from the wifi "base" is probably 40 feet away or so, and works fine with no signal booster or anything. I see that the Blink cameras now have two-way audio. We didn't have that option when we bought ours, but seems like a good feature. You can adjust video capture length, camera sensitivity, etc. We've been happy with our system.
