It was like $25 on Amazon, pretty good deal I think.
Got the rtsp stream connected up to smartthings and blue iris and have had zero trouble with them.
They're only $20 if you order from wyze.com
That being said if you have a video server like MotionEye or maybe Smarthome has it (that was mentioned before), you can likely do some alerting based off that. I know MotionEye has email alerts and might have some other alerting that I don't use.
EDIT: currently 2-3 weeks backordered on wyzecam.com and out of stock on Amazon.
