Perimeter Protection

Utilizing advanced tripwire, Dahua’s Analytics+ technology allows you to monitor a defined area or line for tripwire or intrusion violations. Tripwire alarms are able to distinguish between humans and vehicles, allowing specific monitoring criteria to be set-up. False alarms that would normally be caused due to animals, weather, trees, or light are reduced. This advanced technology helps increase efficiency for video surveillance.

Reduced False Alarms


Human Detection

Establish designated tripwire zones for detecting the presence of a human.

Ideal for locations where only vehicles are permited to help determine if a pedestrian enters, such as main roadway entrances, restricted gate entrances, etc. The tripwire is designed to trigger when a pedestrian enters in to the designated zone and will trigger an alarm. Additionally, data can be searched after the fact to bring up only those instances when a human has appeared, reducing search time after the fact.

Vehicle Detection

Establish designated tripwire zones for detecting the presence of a vehicle.

Ideal for locations where only pedestrians are allowed, such as walk ways or no-parking zones. The tripwire is designed to trigger when a vehicle enters in to the designated zone and will trigger an alarm. Additionally, data can be searched after the fact to bring up only those instances when a vehicle has appeared, reducing search time after the fact.

Detect Humans and Vehicle

Tripwire can be set up in a single scene to alert for both people and vehicles.

Option 1 – One trip wire zone can be set up to trigger when either a human or vehicle enters the scene

Option 2 – Seperate trip wire zones can be set up within the same scene to seperately trigger for either people or vehicles

After events have been recorded, a back-end search conducted for either specific people or vehicle instances will pull based on the tripwire critera set.

Reduced False Alarms

Perimeter Protection technology offers up to 98% accuracy when detecting people and vehicles.

To do so it filters out other common causes of false alarms including: Leaves, animals, rain and shadows.

Filters out Weather

Filters out Pets
