Had Nextbase cameras like the guys above, the 422 and 512, they were OK but the batteries were done in less than 2 years.
Decided to try something new when I got the Q5 - https://www.amazon.co.uk/dp/B0CVXDGNWP?ref=ppx_yo2ov_dt_b_fed_asin_title
4K front and 1080p rear, no batteries to ware out, can be hardwired or not, and (so far) has worked flawlessly. Even the software updates are nice and easy, plus the footage compared to my older Nextbase cams is a lot better.
