Typically, combo controllers are risky, because they combine sensitive door controllers with readers on the exposed unsecured side of the door.
But Hartmann Controls has a different take. Their combo unit is a door controller combined with a motion detector REX designed to be mounted on the secured side of the door. The controller also includes onboard controls that could make it easier for installers.
Inside, we examine Hartmann's controller and management platform Protector.Net, its functionality, pricing and weaknesses, and contrast it against other combo controllers (e.g. HID) on the market.
