Summary
When an Aiphone AX-DV or AX-DVF door station lens gets scratched, there are a few options to repair it.
Solution
If the lens on the video door station gets scratched, we recommend using Novus Plastic Polish Kit.
This kit comes with three types of scratch removers: #1 plastic polish; #2 fine scratch remover; #3 heavy scratch remover.
The same product is widely available online, either in this kit form or individually. We recommend the kit to accommodate all types of scratches.
Since replacement lenses are not always available, and the door station must be completely disassembled and reassembled to replace the lens, we recommend this method before sending a station in for repair.
