Gateway with backup power and communications system

1. A security system gateway device comprising:

a first communications system configured to communicate with a first communications network over a first communications medium;

a second communications system configured to communicate with the first communications network over a second communications medium; and

a controller configured to selectively control communications flows between the first communications system and the second communications system;

wherein selectively controlling communications flows between the first communications system and the second communications system comprises:

identifying a data connection between a first endpoint on the first communications network over a first communications medium and a second endpoint on the first communications network over a second communications medium;

identifying first and second data packets of the data connection;

routing the first data packet through the first communications system over the first communications medium; and

routing the second data packet through the second communications system over the second communications medium.

2. The device of claim 1 , wherein selectively controlling communications flows between the first communications system and the second communications system further comprises:

determining an availability of the first communications network over the first and second communications mediums.

3. The device of claim 2 , wherein selectively controlling communications flows between the first communications system and the second communications system further comprises:

in response to determining that at least one of the first communications system and the second communications system is unavailable, using another of the first communications system and the second communications system as a backup communications system.

4. The device of claim 3 , wherein selectively controlling communications flows between the first communications system and the second communications system further comprises:

determining that the at least one of the first communications system and the second communications system has become available, and using the at least one of the first communications system and the second communications system for communication.

5. The device of claim 1 , wherein selectively controlling communications flows between the first communications system and the second communications system further comprises:

determining a first communications bandwidth to the first communications network through the first communications system;

determining a second communications bandwidth to the first communications network through the second communications system; and

routing communications between the first communications system and the second communications system based on the first communications bandwidth and the second communications bandwidth.

6. The device of claim 5 , wherein routing communications based on the first communications bandwidth and the second communications bandwidth further comprises:

identifying a highest bandwidth between the first communications bandwidth and the second communications bandwidth; and

routing communications between the first communications system and the second communications system based on the identified highest bandwidth.

7. The device of claim 1 , wherein selectively controlling communications flows between the first communications system and the second communications system further comprises:

determining a first cost of communications with the first communications network through the first communications system;

determining a second cost of communications with the first communications network through the second communications system; and

routing communications between the first communications network and the second communications network through at least one of the first communications system and the second communications system based on the first cost and the second cost.

8. The device of claim 1 , wherein the first communications network is the Internet.

9. The device of claim 1 , wherein the first communications medium is a broadband communications link.

10. The device of claim 1 , wherein the first communications medium is the Internet.

11. The device of claim 1 , wherein the second communications medium is a wireless data communications link.

12. The device of claim 1 , further comprising:

a communications port configured to communicate with a second communications network.

13. The device of claim 12 , wherein the second communications network is a local area network (LAN).

14. The device of claim 12 , wherein the controller is further configured to selectively control communications flows between the communications port and at least one of the first communications system and the second communications system.

15. The device of claim 1 , further comprising:

a power circuit comprising:

a first power system configured to power the first and second communications systems with a first power source; and

a second power system configured to power the first and second communications systems with a second power source.

16. The device of claim 15 , wherein the power circuit further comprises a power selection circuit configured to:

determine availability of power from the first power system and the second power system;

selectively source power from the first power source or the second power source based on the determined availability; and

power at least one of the first and second communications systems and the controller with the selectively sourced power.

17. The device of claim 16 , wherein the power selection circuit is further configured to:

determine costs of power from the first power system and the second power system; and

selectively source power from the first power source or the second power source based on the determined costs.

18. The device of claim 15 , wherein the first power source comprises a main power source.

19. The device of claim 15 , wherein the second power system comprises an onboard uninterruptable power supply (UPS).

20. The device of claim 15 , wherein one of the first power source and the second power source comprises a solar power source.
