Abstract

A system and method configured to improve the function of a network of Power Over Ethernet (POE) devices. The system and method is configured such that a digital video recorder (DVR) actively monitors the POE devices using the POE device application programming interface (API). The DVR, in response to a POE failure or non-responsive POE status may automatically power cycle the port of the network switch corresponding to the POE device, or may power cycle (reboot) the network switch. The system and method also may notify a remote user through a wide area network (WAN) and remote monitor, allowing the remote user to alternatively manually power cycle the network switch and/or the POE(s) ports.

First claim

What is claimed is:

1. A method of power over Ethernet (POE) device control, the method comprising:
modifying a digital video recorder (DVR) to automatically control an application programming interface (API) of a network switch;
monitoring a plurality of POE devices with the DVR, wherein the plurality of POE devices and the DVR are connected to the network switch, wherein the network switch includes an application programming interface (API), wherein the POE devices and the DVR are wired or wirelessly connected to the network switch;
detecting with the DVR all nonresponsive POE devices connected to the network switch;
automatically determining, with the DVR, the number of POE devices that are nonresponsive;
automatically utilizing the DVR to instruct the API of the network switch to power cycle the ports on the network switch corresponding to the nonresponsive POE devices when the number of nonresponsive POE devices is less than a predetermined number, wherein the predetermined number is greater than one; and
automatically utilizing with the DVR to instruct the API of the network switch to power cycle the entire network switch when the number of nonresponsive POE devices is at least equal to the predetermined number.

2. The method of claim 1 , wherein the plurality of POE devices are internet protocol (IP) cameras.

3. The method of claim 1 , wherein the plurality of POE devices are sensors.

4. The method of claim 1 , further comprising notifying a remote user of the nonresponsive POE device, wherein the notification is sent through a wide area network (WAN) from the DVR to a remote sensor.

5. The method of claim 1 , further comprising configuring the DVR to not automatically power cycle the nonresponsive POE device, and further comprising allowing the remote user to manually power cycle the nonresponsive POE device with a user interface.

6. The method of claim 1 , further comprising notifying the remote user when the DVR utilizes the API of the network switch to automatically power cycle the nonresponsive POE device or network switch.

7. The method of claim 1 , further comprising monitoring with the DVR the network switch for nonresponsiveness and detecting a nonresponsive network switch.

8. The method of claim 7 , further comprising utilizing with the DVR the API of the network switch to automatically power cycle the nonresponsive network switch.

9. The method of claim 8 , further comprising utilizing with the DVR the API of the network switch to automatically power cycle the network switch after a firmware update is completed.

10. A power over Ethernet (POE) device system, the system comprising:
a plurality of POE devices configured throughout a monitoring area;
a modified digital video recorder (DVR) coupled with the plurality of POE devices through a network switch, wherein the modified DVR is modified to automatically control an application programming interface (API) of the network switch, wherein the modified DVR monitors the plurality of POE devices with the API of the network switch and detects all nonresponsive POE devices, wherein the nonresponsive POE devices are a set of the plurality of POE devices, wherein the modified DVR determines the number of nonresponsive POE devices, wherein the modified DVR automatically utilizes the API of the network switch to power cycle the ports on the network switch corresponding to the nonresponsive POE devices when the number of nonresponsive POE devices is less than a predetermined number, and further wherein the DVR automatically utilizes the API of the network switch to power cycle the entire network switch when the number of nonresponsive POE devices is at least equal to the predetermined number, wherein the predetermined number is greater than one.

11. The system of claim 10 , wherein the plurality of POE devices are internet protocol (IP) cameras.

12. The system of claim 10 , wherein the plurality of POE devices are sensors.

13. The system of claim 10 , further comprising a wide area network (WAN), wherein a remote user is notified of the nonresponsive POE device from the DVR to a remote sensor through the WAN.

14. The system of claim 10 , wherein the DVR is configured to not automatically power cycle the nonresponsive POE device, and further wherein the remote user is allowed to manually power cycle the nonresponsive POE device with a user interface.

15. The system of claim 10 , wherein the remote user when the DVR utilizes the API of the network switch to automatically power cycle the nonresponsive POE device or network switch.

16. The system of claim 10 , wherein the DVR monitors the network switch for nonresponsiveness and detects a nonresponsive network switch.

17. The system of claim 16 , wherein the DVR utilizes the API of the network switch to automatically power cycle the nonresponsive network switch.

18. The system of claim 17 , wherein the DVR utilizes the API of the network switch to automatically power cycle the network switch after a firmware update is completed.

19. A method of controlling power over Ethernet (POE) internet protocol (IP) cameras, the method comprising:
modifying a digital video recorder (DVR) to automatically control an application programming interface (API) of a network switch;
monitoring a plurality of IP cameras with the DVR through the API of the network switch;
detecting with the DVR all nonresponsive IP cameras, wherein the nonresponsive IP cameras are a set of the plurality of IP cameras;
automatically determining, with the DVR, the number of IP cameras that are nonresponsive;
automatically utilizing with the DVR the API of the network switch to power cycle the nonresponsive IP cameras when the number of nonresponsive IP cameras is less than a predetermined number, wherein the redetermined number is greater than one; and
automatically utilizing with the DVR the API of the network switch to power cycle the entire network switch when the number of nonresponsive IP cameras is at least equal to the predetermined number.
