Violet M. ★★★★★ Sep 15, 2026

Hooking this up to the T800 was straightforward, and the exterior mount gives me a clean view of everything behind me instead of a reflection off my rear glass. Night footage from the back is surprisingly clear too.

Avery ★★★★★ Sep 14, 2026

Wasn't sure the exterior mount would hold up through a car wash, but it hasn't budged. The 4K footage of the car behind me is sharp enough to read a plate at night. Only works with the T800, so don't buy it expecting it to pair with anything else.

The in-car rear cam clips in behind the headrest and the cable was long enough to tuck along the trim without an extension. Footage from the back window is way sharper than the grainy clips my old setup gave me.
