Abstract

A sensor unit includes a network video camera and a sensor operable to detect a condition of an environment. A power connector connects the sensor unit to a power line, and a signal connector connects the sensor to a signal line. The sensor is operable to output a signal on the signal line via the signal connector indicating whether the condition of the environment was detected. A network interface is operable to transmit video captured by the network video camera to a remote location via a network. A controller is operable to receive a signal from the sensor indicating whether the condition of the environment was detected. The controller is further operable to control transmission of video captured by the network video camera to a remote location via the network interface based on one or more of access rights of a user and whether the condition of the environment was detected.

Claims

1. A sensor unit comprising:

a network video camera;

a sensor operable to detect a condition of an environment;

a power connector connecting the sensor unit to a power line;

a signal connector connecting the sensor to a signal line, wherein the sensor is operable to output a signal on the signal line via the signal connector indicating whether the condition of the environment was detected;

a network interface operable to transmit video captured by the network video camera to a remote location via a network;

a memory storing access rights; and

a controller operable to receive a signal from the sensor indicating whether the condition of the environment was detected and the controller is further operable to control transmission of video captured by the network video camera to a remote location via the network interface based on one or more of access rights of a user stored in the memory and whether the condition of the environment was detected.

2. The sensor unit of claim 1, wherein the access rights indicate whether the user is authorized to receive the video.

3. The sensor unit of claim 2, wherein the access rights indicate whether the user has rights to receive the video only in an alarm condition.

4. The sensor unit of claim 3, wherein the alarm condition is triggered in response to the sensor detecting the condition of the environment.

5. The sensor unit of claim 3, wherein the alarm condition is triggered in response to receiving a signal from another sensor unit, the signal indicating that a sensor in the another sensor unit has detected a condition of the environment.

6. The sensor unit of claim 1, wherein the network video camera is triggered to capture video in response to an alarm condition.

7. The sensor unit of claim 6, wherein the alarm condition is triggered in response to the sensor detecting the condition of the environment.

8. The sensor unit of claim 1, further comprising a video recognition module operable to determine whether a captured image includes features of a predetermined individual.

9. The sensor unit of claim 1, wherein the power line comprises a two-wire power line wired to a security panel including an AC power supply and battery back-up.

10. The sensor unit of claim 9, wherein the signal line comprises a two-wire line connected to the security panel.

11. The sensor unit of claim 10, wherein the sensor unit replaces a sensor previously installed at a location of the sensor unit, such that the sensor unit is operable to use the power line and the signal line of the replaced sensor at the location.

12. The sensor unit of claim 10, wherein the location is optimal for video surveillance of a zone.

13. An apparatus comprising:

video camera means for generating video of a surveillance area;

sensor means for detecting a condition of an environment;

power connector means for connecting the apparatus to a power line;

signal connector means for connecting the sensor to a signal line and for outputting a signal on the signal line indicating whether the condition of the environment was detected;

network interface means for transmitting video captured by the video camera means to a remote location via a network;

memory means for storing access rights; and

controller means for receiving a signal from the sensor means indicating whether the condition of the environment was detected and for controlling access to video captured by the video camera means based on one or more of access rights of a user stored in the memory means and whether the condition of the environment was detected.

14. The apparatus of claim 13, wherein the video camera means is triggered to capture video in response to an alarm condition.

15. The apparatus of claim 14, wherein the alarm condition is triggered in response to the sensor means detecting the condition of the environment.

16. The apparatus of claim 15, further comprising video recognition module means for determining whether a captured image includes features of a predetermined individual.

17. A method comprising:

identifying an existing sensor in a security system, wherein the existing sensor includes a wired power connection and a wired signal line connection;

replacing the sensor with a sensor unit, the sensor unit including a network video camera and a sensor operable to detect a condition of an environment; and

connecting the sensor unit to the power connection such that the video camera and the sensor in the sensor unit receive power via the power connection; and

connecting the sensor to a signal line via the signal line connection, such that the sensor is operable to transmit a signal on the signal line indicating that an environmental condition was detected.

18. The method of claim 17, further comprising:

storing access rights in a memory for the sensor unit, the access rights being used to control remote access to video captured by the network video camera.

19. The method of claim 18, wherein the access rights include conditions indicating whether users are only allowed to receive the video in an alarm condition

20. The method of claim 17, further comprising:

triggering the network video camera to capture video in response to an alarm condition, wherein the alarm condition is triggered in response to the sensor in the sensor unit detecting the condition of the environment.
