Abstract

A distributed security system includes a detection unit disposed at a first location. The detection unit includes a particle sensor that is configured to detect a particle count in first location. The detection unit also includes a housing enclosing a portion of the particle sensor. The security system also includes a camera disposed at a second location and having a field of vision encompassing the first location. The camera is configured to capture a video of the first location. The system also includes a server communicatively connected to the detection unit and the camera and configured to associate the particle count with the video.

Claims (20)

1. A building management system, comprising:

a trigger sensor configured to enter a scanning mode based on detecting a triggering event at a first location of an environment;

a detection unit disposed at the first location of the environment, the detection unit comprising:

a particle sensor configured to detect a particle count of a substance proximate to the first location of the environment; and

a detection unit housing configured to enclose at least a portion of the particle sensor,

wherein the detection unit is configured to:

periodically check whether the trigger sensor has entered the scanning mode; and

provide power to the particle sensor in response to determining the trigger sensor has entered the scanning mode;

an HVAC system disposed proximate to the first location of the environment, the HVAC system comprising an air filter configured to filter the substance; and

a server communicatively connected to the detection unit and the HVAC system and configured to activate the air filter.

2. The system of claim 1 , wherein the detection unit is further configured to:

determine a detection event based upon the particle count.

3. The system of claim 2 , wherein the server is further configured to activate an air filter system based upon the detection event.

4. The system of claim 1 , wherein the server is configured to determine a detection event by comparing the particle count to a predetermined threshold.

5. The system of claim 3 , wherein the server is further configured to compare the air filter to a specification.

6. The system of claim 5 , wherein the server is further configured to generate a notification based upon the comparison of the air filter to the specification.

7. The system of claim 1 , wherein the server is configured to activate an alarm based upon the particle count.

8. The system of claim 1 , wherein the particle sensor is configured to detect the particle count of a contagion.

9. The system of claim 1 , wherein the server is communicatively connected to the detection unit and the HVAC system via a communication hub.

10. The system of claim 1 , wherein the triggering event comprises a presence of the substance in the first location of the environment.
