naxisVideo-AxisVideoEventCameraExt

This component serves as a container for video surveillance system events that result from motion detected and camera failure.

Figure 55. Proxy Ext properties

To access these properties, expand Config > Drivers > NAxisVideoNetwork > NAxisVideoCamera > Events > Motion Detected and double-click Proxy Ext.

In addition to the standard properties (Status, Fault Cause, Enabled, Device Facets, and Tuning Policy Name), these properties apply to motion detected events.

Property	Value	Description
Conversion	drop-down list (defaults to Default)	Defines how the system converts proxy extension units to parent point units. `Default` automatically converts similar units (such as Fahrenheit to Celsius) within the proxy point. NOTE: In most cases, the standard `Default` conversion is best. `Linear` applies to voltage input, resistive input and voltage output writable points. Works with linear-acting devices. You use the Scale and Offset properties to convert the output value to a unit other than that defined by device facets. `Linear With Unit` is an extension to the existing linear conversion property. This specifies whether the unit conversion should occur on “Device Value” or “Proxy Value”. The new linear with unit convertor, will have a property to indicate whether the unit conversion should take place before or after the scale/offset conversion. `Reverse Polarity` applies only to Boolean input and relay output writable points. Reverses the logic of the hardware binary input or output. `500 Ohm Shunt` applies to voltage input points only. It reads a 4-to-20mA sensor, where the Ui input requires a 500 ohm resistor wired across (shunting) the input terminals. `Tabular Thermistor` applies to only a Thermistor input point and involves a custom resistance-to-temperature value response curve for Type 3 Thermistor temperature sensors. `Thermistor Type 3` applies to an Thermistor Input point, where this selection provides a “built-in” input resistance-to-temperature value response curve for Type 3 Thermistor temperature sensors. `Generic Tabular` applies to non-linear support for devices other than for thermistor temperature sensors with units in temperature. Generic Tabular uses a lookup table method similar to the “Thermistor Tabular” conversion, but without predefined output units.
Read Value	read-only	Displays the last value read from the point.
Write Value	read-only	Displays the last value written to the point.
Most Recent Event	additional properties	Refer to Most Recent Event
Auto Expiration	`true` (default) or `false`	Determines if the software applies the Auto Expiration Interval to events.
Auto Expiration Interval	hours minutes seconds	Defines an interval of time after which a Motion Started event expires (changes to Motion Stopped) if no other events occur. This interval ensures that the camera does not continue to record and store video unnecessarily.
Point Id	additional properties	Refer to Point Id properties
Enable Detection On Boot	`true` (default) or `false`	Turns on and off the detection of camera events when the station starts.

Most Recent Event

Property	Value	Description
Event Type	read-only	Identifies the type of event (Motion Started, Motion Stopped).
Description	read-only	Describes the event.
Timestamp	read-only	Reports when the event occurred.
Is Normal	read-only	Indicates if the event functioned as expected.
Icon	read-only	Identifies the icon associated with the event.
Meta Data	additional properties	Opens a facets window for adding descriptions to associate with events.

Point Id properties

These properties are required by older cameras whose firmware is older than version 5.60. More recent camera so not require you to configure these properties.

Property	Value	Description
Event Server	text	Provides the name of the event server.
Motion Window	text	Provides a name for the window that monitors any type of motion within its boundary. An area of a video screen defines this window.
Action Start	text	Provides text to display when an action begins.
Action Stop	text	Provides text to display when an action ends.
Niagara Event Type	drop-down list	Selects the type of event. `Motion Started` initiates the action of detecting motion. `Motion Stopped` terminates the action of detecting motion. `Tamper` initiates an event due to someone physically manipulating the camera. `Fault` initiates a problem in the camera. `Custom Event` initiates some other event. `Null Event` indicates that no event occurred or was received.
