ZoneMinder Binding

Supports the ZoneMinder video surveillance system.

Supported Things

The following thing types are supported:

Thing	ID	Discovery	Description
Server	server	Manual	Server bridge manages all communication with ZoneMinder server
Monitor	monitor	Automatic	Monitor represents a ZoneMinder camera monitor

Installation

The binding requires ZoneMinder version 1.34.0 or greater and API version 2.0 or greater. It also requires that you enable the OPT_USE_API parameter in the ZoneMinder configuration.

If your ZoneMinder is installed using a non-standard URL path or port number, that must be specified when you add the ZoneMinder server thing.

There are two different styles of operation, depending on whether or not you have ZoneMinder configured to use authentication.

Non-Authenticated

If ZoneMinder authentication is not used, the User and Password parameters should be empty in the ZoneMinder Server thing configuration. No other configuration is required.

Authenticated

The binding can access ZoneMinder with or without authentication. If ZoneMinder authentication is used, first make sure the ZoneMinder user has the API Enabled permission set in the ZoneMinder Users configuration. Then, enter the user name and password into the ZoneMinder Server thing configuration.

Discovery

The server bridge must be added manually. Once the server bridge is configured with a valid ZoneMinder host name or IP address, all monitors associated with the ZoneMinder server will be discovered.

Thing Configuration

Server Thing

The following configuration parameters are available on the Server thing:

Parameter	Parameter ID	Required/Optional	Description
Host	host	Required	Host name or IP address of the ZoneMinder server.
Use secure connection	useSSL	Required	Use http or https for connection to ZoneMinder. Default is http.
Port Number	portNumber	Optional	Port number if not on ZoneMinder default port 80.
Url Path	urlPath	Required	Path where Zoneminder is installed. Default is /zm.
Refresh Interval	refreshInterval	Required	Frequency in seconds at which monitor status will be updated.
Default Alarm Duration	defaultAlarmDuration	Required	Can be used to set the default alarm duration on discovered monitors.
Default Image Refresh Interval	defaultImageRefreshInterval	Optional	Can be used to set the image refresh interval in seconds on discovered monitors. Leave empty to not set an image refresh interval.
Monitor Discovery Enabled	discoveryEnabled	Required	Enable/disable the automatic discovery of monitors. Default is enabled.
Monitor Discovery Interval	discoveryInterval	Required	Frequency in seconds at which the binding will try to discover monitors. Default is 300 seconds.
User ID	user	Optional	User ID of ZoneMinder user when using authentication.
Password	pass	Optional	Password of ZoneMinder user when using authentication.

Monitor Thing

The following configuration parameters are available on the Monitor thing:

Parameter	Parameter ID	Required/Optional	Description
Monitor ID	monitorId	Required	Id of monitor defined in ZoneMinder.
Image Refresh Interval	imageRefreshInterval	Optional	Interval in seconds in which snapshot image channel will be updated.
Alarm Duration	alarmDuration	Required	How long the alarm will run once triggered by the triggerAlarm channel.

Channels

Server Thing

Channel	Type	Description
imageMonitorId	String	Monitor ID to use for selecting an image URL. Also, sending an OFF command to this channel will reset the monitor id and url to UNDEF.

Thing Actions

triggerAlarm

The triggerAlarm action triggers an alarm that runs for the number of seconds specified by the parameter duration.

triggerAlarm - trigger an alarm

void triggerAlarm(Number duration)

Parameters:
duration - The number of seconds for which the alarm should run.

triggerAlarm

The triggerAlarm action triggers an alarm that runs for the number of seconds specified in the Monitor thing configuration.

triggerAlarm - trigger an alarm

void triggerAlarm()

triggerAlarmOff

The triggerAlarmOff action cancels a running alarm.

triggerAlarmOff - cancel an alarm

void triggerAlarmOff()

Requirements

The binding requires ZoneMinder version 1.34.0 or greater, and API version 2.0 or greater. The API must be enabled in the ZoneMinder configuration using the OPT_USE_API parameter.

Rules

The following examples assume you have a motion sensor that is linked to an item called MotionSensorAlarm.

rule "Record When Motion Detected Using Channel"
when
    Item MotionSensorAlarm changed to ON
then
    ZM_TriggerAlarm.sendComand(ON)
end

rule "Record for 120 Seconds When Motion Detected"
when
    Item MotionSensorAlarm changed to ON
then
    val zmActions = getActions("zoneminder", "zoneminder:monitor:1")
    zmActions.triggerAlarmOn(120)
end

rule "Record When Motion Detected"
when
    Item MotionSensorAlarm changed to ON
then
    val zmActions = getActions("zoneminder", "zoneminder:monitor:1")
    zmActions.triggerAlarmOn()
end

rule "Record When Motion Detection Cleared"
when
    Item MotionSensorAlarm changed to OFF
then
    val zmActions = getActions("zoneminder", "zoneminder:monitor:1")
    zmActions.triggerAlarmOff()
end

val int NUM_MONITORS = 6
var int monitorId = 1

rule "Rotate Through All Monitor Images Every 10 Seconds"
when
    Time cron "0/10 * * ? * * *"
then
    var String id = String::format("%d", monitorId)
    ZmServer_ImageMonitorId.sendCommand(id)
    monitorId = monitorId + 1
    if (monitorId > NUM_MONITORS) {
        monitorId = 1
    }
end
