Thinking of getting one of these set ups. 2 cams with the hub, 4k resolution for £199
I wouldn't bother, I found that the eufy cameras I had were shocking on battery life, even worse if you had the spotlight on or set to come on with motion. I then used solar panels but they couldn't keep up with them and was still having to take them down and charge them 1 a month.
I then tried a Reolink wireless one which was much better but didn't record 24/7 (don't think any wireless ones do).
We then had ring spot cams which the battery life was decent on (helped that we had two batteries in so could charge one at a time and keep them going unlike the others with built in batteries).
In the end I went for a Reolink hard wired set, this was after my neighbour was broken into, we got footage of them going through our garden to escape and down past the front of ours but crucial points which could have caught faces weren't recorded.
The Reolink set we got was really easy to install, is really good quality, has the option to add more cameras on and works with both the TV and an app which is great.
Short version: battery cameras are crap, don't waste your time, invest in full setup.
