Door Keeper transforms existing door locks to active protection for homes. Door Keeper includes a powerful motor able to operate all kinds of doors in less than 3 seconds while remaining silent to maximize convenience and comfort. Working with a rechargeable battery, Door Keeper always stays awake with only one recharge per year.
