What is the RS232 used for?
With the RS232 you can trigger the VoiceOff audio unit or a relay through the Kontrol and Kommand device.
The Kontrol & Kommand module allows remote control of third party electrical equipment/systems via the AlienDVR and our Free CCTVWindow software.
The CCTVWindow software sends “Kontrol” signals to the DVR that then forwards them on to a Kontrol & Kommand module or VoiceOff audio unit.
