You can go with a GoPro. I ended up picking up a cheap cam and it works really well. https://www.amazon.com/dp/B07JR1XZ78/ref=sspa_dk_detail_0?pd_rd_i=B07JR1XZ78&pd_rd_w=SSfgk&pf_rd_p=57cbdc41-b731-4e3d-aca7-49078b13a07b&pd_rd_wg=d97Al&pf_rd_r=PNP17M9CA8H08TE6YD2C&pd_rd_r=f3296a1d-983b-4128-8f82-55dba77ed626&s=photo&smid=A15W14ZP5JJQK5&th=1

I ended up buying two AKASO action cameras and a Romoss battery bank. I point the front camera a little to the left and the rear a little to the left as well to get more view of approaching vehicles.

They work pretty well although I wish I had 360 video. It's good on a budget of about $200 with cables and stuff. I think probably a good bit better than what's out there that's more specifically for this purpose.

Anyway. Hope this helps someone. Any questions happy to help.

Cheers,

EGO
