I like the brand Vantrue. They don't make wireless but the wiring part is not as hard as some may think. A few youtube videos and I was able to run all the wires behind the car trim and floor. Then the adapter to have the system run off the car fuse box.

one brand i believe called blackvue or something along those lines has cellular capabilities but very expensive imo.

Also got a large powerbank i use sometimes if I park somewhere and want the system running and not use up the car battery.

I prefer the systems that have suction cup for the front camera so i can take it off sometimes.

But dashcams are a must now a days. Way I have mine setup, some people think its a police radar setup lol.
