Are blockchain cameras really more secure/unhackable?

I’ve had a home camera installed for many years but after hearing about many home cameras getting hacked or the companies themselves selling your data, I decided to take mine down (feels weird and unsafe not to have them up, but i really dont like the idea of someone spying on me in my own home.)

I found a blockchain camera called the Ucam. As it’s a blockchain camera, it can’t be hacked so the feeds and any saved recordings are secure.

I’ve read about this blockchain camera online but does anyone here own one? If so, what has your experience been like? Any advice would be much appreciated.
