Understand you're in an enthusiast forum for cameras. Any place for enthusiasts on the internet is going to skew towards "getting the best" and "everything else is shit" even though plenty of people are happy with the shit.
While I have 5442s, I also have some Blink cameras I got for $13 each on sale. Completely wireless, they only record when they detect motion (and even then the motion detection is somewhat limited to horizontal movement) But still, it was $13 and I can cover all my windows in 5 minutes of work because it doesn't use wires. The quality kinda sucks but it serves as a good enough motion alert.
The deal seems to pop back up every few weeks. Usually limit 3 each time. You also need a blink sync module which I got used off ebay for $20.
Link to previous deal: I would set up a deal alert on slickdeals if you're interested (you'll get a notification next time someone posts about the deal
