Verkada SV20 Series Air Quality Sensors (SV21, SV23, SV25) can be mounted in up to 4 different configurations. The specific configuration depends on your installation constraints and which sensor readings you find most meaningful.
Sensor Reading | Mount Type | Recommendation |
CO₂ Monitoring | Wall mounting at heights around 3–6 ft (.9–1.8m) from the floor will provide the most accurate measurements, due to the density of CO2 compared to fresh air. | Keep sensor at least 5 ft away from any doors or operable windows. |
Air Quality Monitoring & Vape Detection | Ceiling mounting, no more than 8–9 ft (2.4–2.7m) from floors, walls, or ceiling vents for the best performance in measurements. If the height is increased, detection will decrease.
If air quality is not an intended use case, you can mount the device at other heights or orientations. However, this can significantly impact accuracy. | If placed in a bathroom, 1 sensor per 2 stalls is recommended. At least 3 ft (.9m) from vents or walls. |
