One of the basic conditions for low temperature operation of the doorbell is dual-power. Battery-powered devices will start giving up once your thermometer hits negative numbers. D1021doesn’t have this problem as it draws power from the two wires from your existing doorbell.
On top of that, to achieve and maintain an IP65 rating, Tecom uses proper sealing in assembly of all doorbell components. We also integrate IC detector and heating resistors spread over the surface of the circuit board that allow D1021 to function in temperatures as low as -30 degree Celsius (-22 degrees Fahrenheit).
D1021 maintains its 1280×720 image resolution in cold weather, which allows users to benefit from crisp, clear pictures year round.
