Event Management
When something happens on camera site, such as someone walks by, the door opens or
closes, someone breaks into the house – these are all Events . Events which occur in the
environment or were preprogrammed in the camera can be used as Triggers . Triggers cause
the camera to react with Responses . The link between a trigger and its response is governed
by Event Rules . Event rules become active or inactive based upon the Schedule . Each event
rule is designated to one certain trigger type from a specific camera and can carry out multiple
responses. An example rule would be for NVR to send an e-mail to alert the supervisor
( Response 1 ) and trigger alarm ( Response 2 ) when a motion is detected by the camera
shooting the house’s backdoor ( Trigger ) during nighttime ( Schedule ).
How Does NVR 3 Handle Events?
In NVR 3, each camera can be involved in several event rules. As different camera models
possess various capabilities, the supported event trigger types would vary. For example, a PIR
built-in camera can execute a PIR-triggered event rule, while this option is not available to
other models without this feature; similarly, the supported response types would vary by
camera models, for example, go-to-preset behavior can only be executed by PTZ devices. In
addition to cameras or NVR status, NVR can also relate certain non-camera ( transaction data,
door entry of network DI) incidents to a response to create a event rule. The chart below
shows NVR server supported Trigger types and Response types:
