Abstract

An assembly includes a premise security device, a mounting bracket, a first electrical cable, and a second electrical cable. The first electrical cable has a first electrical cable first end, connected to the premise security device controller, and a first electrical cable second end. The second electrical cable has a second electrical cable first end, electrically connected to the premise security device controller, and a second electrical cable second end. When the premise security device housing is coupled to the second mounting bracket portion, the second electrical cable second end is electrically connected to the first electrical cable second end to form an electrical circuit between the premise security device controller and the electrically connected electrical cable second ends. The premise security device controller is configured to monitor the presence of the electrical circuit and generate a tamper signal when the electrical circuit is no longer present.

Claims (34)

1 . An assembly comprising:

a premise security device including a premise security device housing and a premise security device controller, the premise security device controller being coupled to the premise security device housing;

a mounting bracket including a first mounting bracket portion mounted to a mounting surface and a second mounting bracket portion coupled to the premise security device housing;

a first electrical cable having a first electrical cable first end and a first electrical cable second end, the first electrical cable first end electrically connected to the premise security device controller; and

a second electrical cable having a second electrical cable first end and a second electrical cable second end, the second electrical cable first end electrically connected to the premise security device controller, and, when the premise security device housing is coupled to the second mounting bracket portion, the second electrical cable second end is electrically connected to the first electrical cable second end to form an electrical circuit between the premise security device controller and the electrically connected second electrical cable second end and first electrical cable second end,

wherein the premise security device controller monitors the presence of the electrical circuit and generate a tamper signal when the electrical circuit is no longer present.

2 . The assembly of claim 1 , wherein the premise security device controller generates the tamper signal when the second electrical cable second end is no longer electrically connected to the first electrical cable second end.

3 . The assembly of claim 1 , wherein the premise security device controller generate the tamper signal when one or both of the first electrical cable first end and the second electrical cable first end is no longer electrically connected to the premise security device controller.

4 . The assembly of claim 1 , wherein the assembly is configured such that when the premise security device housing is uncoupled from the second mounting bracket portion the second electrical cable second end is no longer electrically connected to the first electrical cable second end.

5 . The assembly of claim 1 , further comprising:

a fixation element mounts the first mounting bracket portion to the mounting surface,

wherein the second electrical cable second end is electrically connected to the first electrical cable second end via the fixation element.

6 . The assembly of claim 1 , further comprising:

a mounting plate mounts to the mounting surface adjacent the first mounting bracket portion,

wherein the second electrical cable second end is electrically connected to the first electrical cable second end via the mounting plate.

7 . The assembly of claim 6 , wherein the first mounting bracket portion is mounted to the mounting surface over the mounting plate.

8 . The assembly of claim 1 , further comprising:

a mounting plate mounts to the mounting surface adjacent the first mounting bracket portion; and

a fixation element mounts the mounting plate to the mounting surface,

wherein the second electrical cable second end is electrically connected to the first electrical cable second end via the fixation element.

9 . The assembly of claim 8 , wherein the mounting plate is nonconductive.

10 . The assembly of claim 1 , wherein the premise security device controller monitors the presence of the electrical circuit by monitoring at least one of electrical current and electrical resistance.

11 . The assembly of claim 1 , wherein each of the first electrical cable first end and the second electrical cable first end is electrically connected to the premise security device controller within the premise security device housing, and wherein each of the first electrical cable and the second electrical cable extend through an interior of the mounting bracket.

12 . The assembly of claim 1 , wherein the premise security device includes a camera unit at the premise security device housing.

13 . A method comprising the steps of:

monitoring, via a premise security device controller of a premise security device, the presence of an electrical circuit, the premise security device includes a premise security device housing and the premise security device controller is coupled to the premise security device housing, wherein the premise security device housing is mounted to a mounting surface via a mounting bracket, wherein the electrical circuit is formed between the premise security device controller, a first electrical cable, and a second electrical cable, wherein the first electrical cable has a first electrical cable first end and a first electrical cable second end, the first electrical cable first end electrically connected to the premise security device controller, wherein the second electrical cable has a second electrical cable first end and a second electrical cable second end, the second electrical cable first end electrically connected to the premise security device controller, and, when the premise security device housing is mounted to the mounting surface via the mounting bracket, the second electrical cable second end is electrically connected to the first electrical cable second end to form the electrical circuit between the premise security device controller and the electrically connected second electrical cable second end and first electrical cable second end; and

generating a tamper signal when the electrical circuit is no longer present.

14 . The method of claim 13 , wherein the premise security device controller generates the tamper signal when the second electrical cable second end is no longer electrically connected to the first electrical cable second end.

15 . The method of claim 13 , wherein the premise security device controller generates the tamper signal when one or both of the first electrical cable first end and the second electrical cable first end is no longer electrically connected to the premise security device controller.

16 . The method of claim 13 , wherein when the premise security device housing is no longer mounted to the mounting surface via the mounting bracket the second electrical cable second end is no longer electrically connected to the first electrical cable second end.

17 . The method of claim 13 , wherein a fixation element mounts the mounting bracket to the mounting surface, and wherein the second electrical cable second end is electrically connected to the first electrical cable second end via the fixation element.

18 . The method of claim 13 , wherein a mounting plate is mounted to the mounting surface adjacent the mounting bracket, and wherein the second electrical cable second end is electrically connected to the first electrical cable second end via the mounting plate.

19 . The method of claim 13 , wherein a mounting plate is mounted to the mounting surface, via a fixation element, adjacent the mounting bracket, and wherein the second electrical cable second end is electrically connected to the first electrical cable second end via the fixation element.

20 . The method of claim 13 , wherein the premise security device controller monitors the presence of the electrical circuit by monitoring for a predetermined alteration in at least one of electrical current and electrical resistance.
