Axis Video Network tab

This view configures an Axis Video Network, which is primarily used for reader devices.

Figure 210. Axis Video Network tab

You access this tab from the main menu by clicking Controller Setup > Remote Devices > Remote Drivers followed by double-clicking the Axis Video Network row in the table.

Properties

In addition to the common Status, Enabled, Fault Cause and Health properties, this tab includes these properties.

Property	Value	Description
Alarm Source Info	additional properties	Links to a set of properties for configuring and routing alarms. These properties are documented in the Alarm Setup topic of the PDF and in the help system (search for Alarm Source Info).
Monitor	additional properties	Configures ping properties. Refer to Monitor properties.
Tuning Policies	additional properties	Defines the assigned tuning policy. Refer to Axis Network Tuning Policy (later in this topic).
Fox Video Stream Preferred	`true` or `false` (default)	For a network component, selects (`true`) or declines (`false`) the use of Fox streaming. For a child component (DVR, NVR or camera), selects or declines the use of Fox streaming at the child component level. `Inherit` sets this property to the value set for its parent component (the DVR, NVR or network component). `Yes` sends the video stream from the video camera to the station (controller) and then forwards it to the Workbench interface through the standard Fox/Foxs connection. This overcomes fire wall issues in the event that the video surveillance system is not exposed to the outside world on its network. NOTE: This option assumes that the controller is exposed - otherwise you could not even connect to the station. `No` sends the video stream directly from the video camera to the interface. Using this setting allows you to set the `Preferred Resolution` and `Frame Rate` to `High` without impacting CPU usage. In essence, this removes the station from the equation. In all cases, the client-side computer expends some of its CPU utilization to render the video on the screen.
Discovery Preference, Do Not Ask Again	`true` or `false` (default)	`true` uses the fox connection to route video output from the camera to the station. `false` disables this feature.
Discovery Preference, Timeout	hours, minutes, seconds	This is the setting for specifying how long to try to discover an Axis camera before going to a timeout state.
Use Tls	`true` (default) or `false`	Configures secure communication between the station and network devices. By default, the system uses TLS secure communication. You would change this network property to `false` only if a legacy device (camera) cannot support TLS. If some devices on your network support TLS and others do not, you may add two networks of the same type: one for the secure devices, and the other for those that do not support security.
Tcp Ip Port	number (defaults to 9797)	Identifies the network port, which connects the station to the network. If you have more than one Axis network in your system, each network requires its own unique port. As a best practice, consider using the default port (9797) for a legacy network with cameras that to not support security. When you create a second network for the camera(s) that support security, change this value to 9798.

Monitor properties

Property	Value	Description
Ping Enabled	`true` (default) or `false`	Turns the monitor ping on and off. `true` each network device receives a ping, as needed. `false` no network device receives a ping. Device status remains as recorded the last time this property was `true`. Recommendation: leave `Ping Enabled` as `true` in almost all cases.
Ping Frequency	`hours:minutes:seconds`	Specifies the interval between periodic pings of all devices. Typical default value is every 5 minutes (05m 00s), you can adjust differently if needed.
Alarm on Failure	`true` (default) or `false`	Controls the recording of ping failure alarms. `true` records an alarm in the station’s AlarmHistory for each ping-detected device event (down or subsequent up). `false` ignores device down and up events.
Startup Alarm Delay	`hours:minutes:seconds`	Specifies how long a station waits at startup before generating a device down or up alarm. Applies only if the Monitor’s `Alarm On Failure` property is `true`.

Axis Network Tuning Policy

During polling, the system uses the network driver’s tuning policy to evaluate both write requests and the acceptability (freshness) of read requests.

Property	Value	Description
Min Write Time	hours minutes seconds, zero (default) to infinity	Specifies the minimum amount of time allowed between writes to writable proxy points, especially ones that have one or more linked inputs. This provides a way to throttle rapidly changing values so that only the last value is written. The default value (0) disables this rule causing all value changes to attempt to write.
Max Write Time	hours minutes seconds, zero (default) to infinity	Specifies the maximum amount of time to wait before rewriting the value, in case nothing else has triggered a write, to writable proxy points. Any write action resets this timer. The default (0) disables this rule resulting in no timed rewrites.
Stale Time	hours minutes seconds; defaults to 0 (zero)	Defines the period of time without a successful read (indicated by a read status of {ok}) after which a point’s value is considered to be too old to be meaningful (stale). A non-zero value causes the point to become stale (status stale) if the configured time elapses without a successful read, indicated by Read Status {ok}. The default value (zero) disables the stale timer causing points to become stale immediately when unsubscribed.
