I used to run sj4000s front and back but after changing out cams twice within a year, I upgraded to the
Falcon Zero F360. I appreciated the falcon until I negligently left my car unlocked overnight to find that some sticky finger took advantage and stole all that the could out of my truck.
I have since added the OWL cam to the mix now that it works with android phone. It uses an LTE network and records to a cloud.

This cam is more of a security cam that is continuously on and has sensors, triggered by the attempted opening of a door or even someone bumping on your vehicle.
It uses power via the diagnostic Port (OBD II).
You receive alerts to your phone when there is a suspected break in, albeit the timing of the alerts I have so far found to be inconsistent sometimes right away to 30 mins later. I want to think this may be because of network availability.
I am so far, still satisfied with this false sense of security
