Product Description
The Wireless Input Expander is a conversion device that connects third-party detectors to Dahua Wireless Hub. When the alarm of the third-party detector is triggered, the Expander transmits the signal to the Hub via RF, and then the Hub reports it to platforms. Different alarm types can be configured in the DMSS APP depending on the types of connected detectors. The Expander has a triaxial accelerometer to prevent the device from moving. There is also an input channel to connect the tamper port of the third-party detectors. The Expander is powered by dry batteries and can also supply power for detectors connected to it.
