We are looking into getting some wireless home security cameras for outside the house. I would love to go with a wired setup, but the layout/finishing of our house would make that more difficult and costly than I would probably like. I have the ability to get to an outlet with a couple of them...

Here's a link to a thread I started a few months ago about the same topic if you want some more opinions. We ended up going with Blink because they were dirt cheap on Prime Day - We got 5 cameras for $170. Overall I would say we have been satisfied, but went in with tempered expectations knowing we were going with the cheapest option. We will likely upgrade to something better at some point, but Blink is serving us well enough that we aren't in a rush.
Pros:
-Cheap
-Excellent App, very easy to set up and use
-Subscription free option
Cons:
-Blink intentionally cripples functions if you choose not to purchase the subscription, which sucks
-If you live in an area with lots of wildlife or blowing trees/plants, you will get a lot of false alerts unless you can easily mark the areas as exclusion zones (Gen 4 may have helped fix this with person detection)
-Limited motion detection range, <12 ft is excellent, 12-20 ft is inconsistent, beyond 25 ft is non-existent
-Takes 2 lithium Ion batteries per camera which can get expensive. Ours have been up since July and haven't needed changed yet
