Another shout for Reolink, I have 2 mains powered wifi ones, both have 128GB mSD cards in, both record to the mSD during the night (after NAS has shutdown) then when my NAS powers up in the morning they are scheduled to start automatically send recordings to the NAS, if needed any files recorded overnight on the mSD can be downloaded, get notifications when they are activated by movement.
We’ve been looking at this as well, we’ll be building in town and security is a concern. I’ll need cameras on the front and rear doors as well as the upstairs verandas. There’s lots of good options these days many are wireless and accessible by your phone and a lot cheaper than they were 10 or 15 years ago.
And better quality too, I opted for a wireless solution, it was easy enough to set up and the software is quite capable. Cameras and recorders don’t last forever if spending a lot be aware that it will all need replacing again at some point in the not too distant future.
Mind you digital is a huge improvement over VCR tapes and recorders which were more or less classed as consumables. Ouch!
Yes but the problem with cheap systems is they give constant false readings due to various conditions and you end up switching the notifications off (particularly at night) or something, making them a total waste of time. Who wants a photo of a burglar the next day? Yes the police are going to track someone down for nicking your garden statue aren’t they?
I have a Eufy system and it’s great. I year battery life in the camera’s, great image quality and the recordings are stored locally on the base station - subscription and cloud storage are optional. Definitely recommend.
