Bradley Chambers posted a HomeKit Secure Video wish list asking for 2K camera support, continuous recording, and higher camera limits (you are currently limited to five). I agree with all of these points, particularly the last one.
With HomeKit Secure Video, Apple has a solution that lets its users securely store video in the cloud without paying a third-party vendor. More importantly, unlike all of the camera vendors that want to store your video for you, Apple is not a company likely to be bought up by a bigger company, making your video data part of a financial transaction.
I have been using HomeKit Secure Video with my eufy cameras, and it works great. I’d really dig it, however, if Apple let me put more than five cameras into the system.
