Synology has some fairly strong products in this space. A fairly cheap NAS from them for local storage, and then basically any ip camera you can find will mostly just work. (NAS I'm using: https://www.amazon.com/Synology-Bay-DiskStation-DS220-Diskless/dp/B087ZCBWFH/ref=sr_1_2?crid=3CJFK9DH67GS2&keywords=ds220%2B&qid=1657731166&s=electronics&smid=ATVPDKIKX0DER&sprefix=ds220%2B%2Celectronics%2C100&sr=1-2 https://www.amazon.com/Synology-Bay-DiskStation-DS220-Diskle...) They offer surveillance station (https://www.synology.com/en-us/surveillance https://www.synology.com/en-us/surveillance) as a free app for most of their models. My entire setup (3 cameras, NAS, hdds, POE switch) cost me under $1000, and I get pretty much every feature that most of these cloud camera services offer. - Remote viewing on my phone (https://play.google.com/store/apps/details?id=com.synology.DScam&hl=en_US&gl=US https://play.google.com/store/apps/details?id=com.synology.D...) - Activity alerts and optional triggers for recording - Viewing through any browser - Multiple user accounts Plus if I want it, Surveillance station has a whole host of other features that I currently don't need, but are nice to have (ex: automated cloud backups, offsite storage, CMS, Action rules, etc) As a nice little bonus - I pay zero in monthly costs for this outside of the power to run the cameras & NAS My initial setup cost ran slightly higher than something like Nest or Google Home (ex: I paid 1k vs the roughly 400 it would have cost to buy the cameras from a cloud service) but 4 years in I'm now in the positive on the investment, since I don't have a recurring 14/month subscription charge. So long story short - It's still my data, it's costing me less over time, and I get feature parity. The downside is it requires a little more configuration and setup.
