I live in a house with a lot of new construction around, and some *** kept running turning around in our driveway and running over the sprinkler head... so we decided to catch him.
I got the Arlo pro which includes sound and can be set to record on sound as well as motion.
I got the two camera system - one for the front door and one mounted on the second story looking out over the driveway.
The best part is that there's no power or network drops required.
The one at the door works great. Records crystal clear audio and video and you can even use it as a two way if someone's standing there. Also only needs to be charged about once every 6 months or so.
The one over the driveway works, but I haven't been able to fine tune the settings yet - either it records too often (leaves or insects going by) which causes the camera goes about 7-10 days before it needs to be charged again; or when I adjust the sensitivity it misses too much.
All in all, it's a good system - I get alerts on my phone for my door - and I have it setup to not alert for the driveway - and can look in live if I need to in 720p.
I bought a couple Arlo cameras at Costco for like $150. Battery powered, have a week's worth of video storage in the cloud for free. They only record when they sense motion, but you can set how long they record for. They seem to work fine and were really easy to set up. No audio with them, but also no monthly fee for the basic plan.
