  • Little tricks after the test

    Video recorders

    The DVR module is very much like a microcomputer, in fact it is. During long-term work of the device in reality I met the situations when the module “hangs” without any visible reason or external influences. It is not a problem if you can forcibly reset it by pressing a paper clip, ball-point pen or a match struck to the special Reset button hole on the device.

    The recorder draws almost no current when it is turned off. A fully charged built-in battery discharges in active mode display on, recording cyclically within 2 hours and 20 minutes.

    About the same characteristics and appearance has a DVR-02, which is installed inside the car – on the windshield with the included holder.

    Oysters DVR-02 features automatic recording start in response to motion or sound, which makes it more convenient to use the DVR and allows you to use it not only in the car, but also as part of the security system of any, including country houses.
