The B40 / A118 fits a lot of good components into quite a small form factor. All the above noted components, fit into a small 72mm x 52mm x 43mm casing and can be very discreetly mounted behind the rear view mirror in a vehicle. The method of mounting allows the majority of the camera to be mounted above the windshield with only really the lens and black casing visible from the outside, making it difficult to pick out unless you know it’s there. It also comes with a CMOS battery making it far more tolerant of high and low temperatures.

Common issues

There are a few reported faults with the camera that have been reported by multiple owners. They are as follows:

  • Blurry picture

    A few owners have reported a blurry image after a 10-15 minutes of driving. This is typically due to heat built up behind the camera lens but is supposed to be dissapated by the camera. If this happens, you may want to look at trying to get a replacement unit..

  • Card Full Error

    It has been reported on a few models that the error “Card Full” appear on the screen. The simple solution to this seems to be toggling to a different loop time and then back to your preferred time frame. If the issue persists, you can swap out to a new SD card, this appers to fully resolve the issue..

  • Year changes to 2014

    A number of people have reported that when attaching a compitble GPS unit, the year in the timestamp appears to revert to 2014 (with the date and time remaining correct). A few owners have had success with rolling back to a previous firmware but make sure to read instructions carefully before doing so and only use firmware from your cameras manufacturer.
