How long do aftermarket backup cameras typically last?

Specialist forum threads in our data suggest 2-5 years is a realistic expectation for mid-priced wireless and solar models, with failures most often tied to weather sealing, battery degradation on solar units, or transmitter issues. Wired cameras with metal housings and IP69K ratings (like the PixelMan PMD2A-S referenced in r/CarAV) tend to outlast plastic wireless units, especially in cold climates.
