I received it in a promo email from Amcrest. Recommend signing up if you are on the lookout but not ready to buy yet. All of the promos they send me link to the Amazon product page and you put in the coupon code at checkout. There is also a 5MP version with the Starvis sensor for $50 after coupon LH4QSBYQ: https://www.amazon.com/Amcrest-5-Megapixel-NightVision-Weatherproof-IP5M-T1179EW-28MM/dp/B083G9KT4C/

I have since gone away from BlueIris and am using QVR Pro with my QNAP NAS fwiw. Cameras are still awesome and I would buy 2 more if I felt like running the cable and installing them.
