[Closed] Cameras for comuting bike (Front and rear)

I've been contemplating getting cameras for the comuting/road bike for a long time and given recent insanity on the roads (in Bradford/Leeds road cycling is a full contact adrenaline sport!) I've decided it's time to stop faffing and buy something.

I know I want 2 cameras: front (helmet) and rear (seatpost)  to cover both directions and these need to be fairly sensible prices.

They also need to be admissible in court if needed, show the date in the shot, not have too wide an FoV (i.e. not go-pro) and not stick out too much in the case of the helmet camera

But all the articles I've read are either out of date or are rather general in their conclusions about a camera so I have no idea what actually works well in real life.

Anyone offer any experience?

Thanks
