Side-by-Side Comparison

Feature HALO Smart Sensor Verkada Environmental Sensors
Vape Detection THC, nicotine, smoke particulate Basic vape detection
Air Quality PM2.5, CO2, CO, NO2, VOCs, humidity, temp Temperature, humidity, PM2.5
Gunshot Detection Acoustic gunshot detection Not available
Audio Analytics Aggression, keyword detection Not available
Occupancy Counting People counting included Available via cameras
Chemical Detection Gas leaks, cleaning chemicals Not available
Privacy No camera, no audio recording Sensor-only (no camera)
Integration Open API, works with any VMS Verkada platform only

Our Verdict

HALO is the stronger dedicated environmental sensor with deeper detection capabilities including gunshot detection, chemical detection, and keyword/aggression audio analytics. Verkada sensors are simpler and integrate tightly with Verkada cameras, but lack the detection depth that schools and sensitive environments require.

  1. The HALO 3C detects vape smoke including nicotine and THC, plus attempts to mask them, and adds aggression detection analytics and five programmed spoken keyword triggers with no audio or video recording. People counting and occupancy tracking are exclusive to the HALO 3C-PC model. [source] · verified 2026-07-01
  2. HALO states the 3C and 3C-PC typically cover 144 sq ft for vape detection at normal 8-foot ceiling heights, while their other sensors work effectively up to 1,963 sq ft. [source] · verified 2026-07-01
  3. HALO's acoustic gunshot detection covers 360 degrees at a 25-foot radius (50-foot diameter), protecting a room up to 1,960 sq ft from a single sensor, and it analyzes sound for safety events without recording conversations. [source] · verified 2026-07-01
  4. Motorola Solutions acquired IPVideo, the Bay Shore, New York creator of the HALO Smart Sensor, in a deal announced as completed on December 18, 2023. HALO now sits in the Motorola Solutions portfolio rather than standing alone under IPVideo Corporation. [source] · verified 2026-07-01
