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 (17)

1 . A distributed security system, comprising:

an entry unit configured to detect movement within an environment;

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

a particle sensor configured to detect a particle count proximate to the first location of the environment in response to the entry unit detecting the movement within the environment; and

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

a camera unit disposed at a second location of the environment, the camera unit comprising a field of vision encompassing the first location and the camera unit configured to capture a video of the first location; and

a server communicatively connected to the detection unit and the camera and configured to associate the particle count with the video.

2 . The system of claim 1 , wherein the server 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 associate the particle count with the video based upon the detection event.

4 . The network of claim 2 , wherein the server is further configured to activate the camera unit based upon the detection event.

5 . The system of claim 2 , wherein the server is further configured to display the video based upon the detection event.

6 . The system of claim 1 , wherein the server is configured to activate a second camera unit based upon the particle count.

7 . The system of claim 1 , wherein the particle sensor is configured to detect the particle count of an emission of an electronic nicotine delivery system.

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

9 . The system of claim 1 , wherein the camera unit further comprises a memory and a housing partially enclosing the camera unit and the memory.

10 . The system of claim 9 , wherein the camera unit is configured to store the video in the memory based upon the particle count.
