Our recommendation
Buy the Solar4 if your car parks outdoors and you want the camera working today with zero wiring. Buy the ERT01 if the car is a keeper, parks in a garage, or you simply trust copper more than batteries. The honest trade is installation effort now versus charging habits and wireless latency forever.
Installation
Solar4: plate screws and a socket plug, measured in minutes. ERT01: a cable routed the length of the car plus a reverse-power tap, measured in hours. This single difference decides most purchases, and rationally so.
Picture discipline
The wired ERT01 never lags, freezes, or degrades with distance, and its IP69 camera and night array are the toughest here. The Solar4 picture is a stable 1080P feed with a small wireless latency and ordinary weather sealing.
Ownership over years
The ERT01 asks nothing after install day. The Solar4 asks for sunlight, or periodic USB top-ups for garaged cars, and its battery will age over years. Low-maintenance personalities should weight this honestly.

Questions, answered
Which has the better image?
For stability and night toughness, the ERT01. For screen size and daylight clarity, the Solar4's 1080P feed on a 7-inch screen leads. Neither matches a modern factory head-unit camera for integration.
Which is cheaper overall?
The ERT01 kit costs less, but a paid wired install can erase the gap. Self-installing the Solar4 makes it the cheaper total for most owners.
Which works on a leased car?
The Solar4, clearly: no wiring changes and complete removal in minutes at lease end.
