Ubiquiti has recently launched a new rubber cover for the G4 Instant camera which is made for UniFi Protect. Ubiquiti offers three colours, light grey, grey and dark grey. The camera itself is white so there is no need for a white cover. The only covers missing are wood effect and other colours, like Ubiquiti offers for the G3 Flex and G4 Doorbell.
The cover costs £9.95 in the UK from the official Ubiquiti store. In the EU it is €12.00 and the US for $11.
However, in all three regions it is listed as “coming soon” so should be available soon.
