Sensor Inputs
You can attach external sensors such as infrared sensors, smoke detectors, proximity
sensors, door sensors, etc., to the AVerMedia NV7000’s input-signal connectors on
the I/O 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
NV7000’s output connectors (relay output). You can then configure the system to
activate or deactivate these devices.
