Sensor Inputs
You can attach external sensors such as infrared sensors, smoke detectors, proximity sensors,
door sensors to the AVerMedia digital surveillance system’s input-signal connectors on the I/O
Audio Card. These devices trigger the system to respond with a predefined action (e.g. record
video).
Relay Outputs
You can also attach external output control devices such as alarms to the AVerMedia digital
surveillance system’s output connectors (relay outputs). You can then configure the system
to activate or deactivate these devices. Each AVerMedia video capture card supports 3 relay
outputs. Two of them are normally open relays with one being a toggle switch.
