Camera IVS Tripwire Setup

A tripwire allows you to create an individual line or perimeter that when crossed sets off an event. These tripwires can be either unidirectional or bidirectional and depending on settings, these events can trigger recording, take a snapshot and forward it to a configured e-mail, or send a push notification to a mobile device running ICRSS Pro. Tripwires can also be used with PTZ cameras to track objects that cross the perimeter. Tripwires are commonly deployed around a property border or in front of gates.

Setup Instructions

• Use Internet Explorer to log into the device's IP address
  • This can be done within either the recorder or camera, but the menus will look slightly different
• Install the plugins if prompted
• Navigate to Smart Plan by going to Setup → Event → Smart Plan

• Enable IVS, it looks like a light bulb, then select IVS from the menu
  • Be sure to click SAVE or the settings will not save
• Next navigate to IVS

• Click the green ‘+’ button in the rule window to create a new rule
  • The rule type will be tripwire by default

• Click the draw rule button underneath the image and create your perimeter
  • Right-click when you’re done drawing the tripwire to create the rule

• You can use the target filter to create a minimum/maximum-sized object that will trigger an event
  • The positioning of the filter does not matter
• Select your direction from the parameters menu
  • A → B, B → A, or A ↔ B
• Select desired alert options, i.e. snapshot, send e-mail, alarm upload, etc
• Save the configuration

Conditions and Restrictions

• Cameras are recommended to be mounted vertically at least 15ft. The wider the viewing angle the better IVS will operate. IVS can still work if mounted lower but it will not be as consistent
• Specifically related to PTZ cameras, it is recommended to have the camera stationary for at least 3 minutes to calibrate, i.e. every time the camera moves it will need to sit in the same place for 3 minutes
• The analytics have to recalibrate in high contrast situations, e.g. a door opens in a dark garage and light comes flooding in.
  • This recalibration usually takes a few seconds and the event may be missed. In situations like this, motion detection may be better to use
• The size of the rule should be within 20-33% of the entire image. The wider the viewing angle, the larger the rule can be
• Don’t draw rules along the edge of the image. The analytic system needs to be able to see objects coming and going and if the rule touches the edge of the image that makes this impossible
• Tripwires can only be used with intrusion zones or other tripwires. It cannot be used with other IVS types
