Abstract

A digital video system including one or more video cameras and a video server connected to the one or more video cameras is disclosed. In an illustrative embodiment, the video server includes a computer having a central processing unit (CPU) for executing machine instructions and a memory for storing machine instructions that are to be executed by the CPU. The machine instructions when executed by the CPU implement a number of functions including receiving one or more trigger event conditions, receiving data relating to the one or more trigger event conditions, generating a trigger event message based on a comparison of the one or more trigger event conditions and the data relating to the one or more trigger event conditions, and transmitting the trigger event message.

Claims

1. A digital video system comprising:

one or more video cameras;

at least one video server connected to the one or more video cameras, the at least one video server including a computer having a central processing unit (CPU) for executing machine instructions and a memory for storing machine instructions that are to be executed by the CPU, the machine instructions when executed by the CPU implement the following functions;

receiving one or more trigger event conditions;

receiving data relating to the one or more trigger event conditions;

receiving a trigger user preference to be performed based on the one or more trigger conditions;

generating a trigger event message based on a comparison of the one or more trigger event conditions and the data relating to the one or more trigger event conditions; and

transmitting the trigger event message and the trigger user preference to be performed to a client computer that performs a trigger event function according to the trigger user preference.

2. The digital video system of claim 1, wherein the trigger event message includes data relating to the at least one video server.

3. The digital video system of claim 1, wherein the trigger event message includes the server ID or port number.

4. The digital video system of claim 1, wherein the data relating to the one or more trigger event conditions includes sensor data.

5. The digital video system of claim 1, wherein the data relating to the one or more trigger event conditions includes switch data.

6. The digital video system of claim 1, wherein the transmitting function includes transmitting the trigger event message to a client computer over a network.

7. The digital video system of claim 1, wherein the at least one video server is integrated with the one or more video cameras.

8. The digital video system of claim 1, wherein each of the at least one video servers are integrated with one of the one or more cameras.

9. The digital video system of claim 1, wherein the one or more video cameras are IP video cameras.

10. The digital video system of claim 1 further comprising a sensor or switch connected to the at least one video server.
