Activity Sensors

Know what’s happening before you roll a truck. MAXSUR activity sensors deliver early warning for people, vehicles, and perimeter breaches—built for remote sites, critical infrastructure, and covert monitoring.

Explore Sensors How It Works
Wireless deployments Long-range alerting Scales from single site to enterprise
Detect
Human motion, vehicle movement, and perimeter crossings.
Confirm
Cue cameras and workflows to reduce nuisance dispatch.
Respond
Trigger notifications and escalation in seconds.
Scale
Standardize across sites, yards, substations, and corridors.

Field-proven sensing for real-world environments

Activity sensors are the fastest way to create a reliable “tripwire” for remote operations. They’re ideal when you need early warning without lighting up a site with obvious hardware. Use them standalone for alerting—or as the front-end trigger for cameras, recording, and response workflows.

Best-fit applications
  • Remote gates, drive lanes, and perimeter entrances
  • Substations, yards, laydown areas, and storage lots
  • Pipeline, water, rail, and right-of-way monitoring
  • Temporary coverage during construction or outages

Sensor lineup

Mix-and-match sensors to cover the approaches that matter most—people, vehicles, and boundary crossings.

Wireless PIR Sensor

Motion detection for foot traffic & approach paths

Detect human movement where cameras alone can struggle—tree lines, access trails, gates, equipment pads, and approach corridors.

  • Ideal for covert, rural, and low-light environments
  • Early warning for approach and loiter events
  • Pairs well with fixed cameras for verification

Wireless Vehicle Detector

Detect vehicles entering or moving within your site

Monitor drive lanes, access roads, and service approaches to capture vehicle activity before it reaches critical assets.

  • Great for long driveways and remote site access
  • Triggers camera focus, recording, and notifications
  • Helps separate vehicle events from foot traffic

Wireless Beam Break

Perimeter crossing detection you can aim and control

Create a clean boundary at gates, walk-through points, or fence-line gaps using a beam pair. Best when you need a “hard line” tripwire.

  • Strong for gates, entrances, and defined choke points
  • Reduces nuisance alerts vs. wide-area sensing
  • Excellent trigger for PTZ presets or spot cameras

Smart Sensor

Flexible triggering for multi-sensor logic & workflows

Use a smart sensor as a configurable input for your operational needs—combining signals, reducing false alerts, and supporting site-specific escalation logic.

  • Build multi-sensor “AND/OR” style alerting concepts
  • Supports layered detection (approach → verify → respond)
  • Ideal for enterprise standardization across sites

How it works

A layered approach to detection that reduces nuisance alerts and improves response time.

1
Deploy sensors at the most likely approaches
Gates, access roads, fence-line crossings, and blind zones.
2
Trigger verification
Use alerts to cue cameras, recording, or quick checks by your team.
3
Escalate the right events
Tune thresholds so only actionable events become dispatches.
Pro tip: Pair a beam break at the “hard line” (gate/fence) with a PIR on the approach path and a vehicle detector at the drive lane for clean, high-confidence detection.
