Overview
A direct fit replacement rear camera for the Wolfbox G840S, G840H, G930, G850 and G900 Core dash cam systems, using the original 20 foot cable and connector so it swaps in for the stock unit without rewiring.
This is a compatibility part, not a standalone backup camera, and the fit list is the whole story: it works with the G840S, G840H, G930, G850 and G900 Core, but Wolfbox is explicit that it will not work with the G900 Tripro Cabin version or the G900PRO's USB-C six pin rear camera. Buyers replacing a cracked or foggy stock lens are the target, not anyone shopping for a universal add-on camera.
- 20 foot factory length cable included
- Rated -20 to 70C operating temperature
- 1080P AHD output
- Plug and play with compatible Wolfbox units
Who it's for
Owners of a compatible Wolfbox dash cam whose factory rear camera has failed, fogged or cracked, and who want a swap-in part rather than a new dash cam system. Not for anyone with the G900 Tripro Cabin or G900PRO version, which use a different connector entirely.
Pros and cons
- Uses the original 20ft cable and connector
- IP67 rated for outdoor exposure
- WDR and HDR aid low light and glare
- Not compatible with G900 Tripro Cabin or G900PRO
- Manual screw tightening needed on install
Performance notes
The listed WDR and HDR processing balances bright and dark areas of the same frame, which matters most at dusk or under headlights where a plain 1080p sensor would blow out highlights or lose the plate in shadow. The IP67 rating and the -20C to 70C operating range point to a part meant to sit outside the cabin permanently, not a fair weather accessory.

Frequently asked questions
Will this work with my Wolfbox G900PRO?
No. Wolfbox states it is not compatible with the G900PRO or G900 Tripro Cabin version, both of which use a USB-C six pin rear camera connector instead.
Does the Wolfbox rear camera need a new cable run?
No, it ships with a 20 foot cable matching the original, so it replaces the stock camera using the existing wiring path.
Is this rear camera waterproof?
It carries an IP67 rating and an operating range of -20C to 70C, which covers rain, snow and hot exterior mounting.
