## Abstract

The present invention provides a video surveillance apparatus and method of operation for a system having at least one predefined setting. A first parameter corresponding to an alignment of a video camera assembly with a visual target is stored. A second parameter corresponding to the alignment of a modified video camera assembly with the visual target is obtained. A difference between the first and second parameters is determined. The difference is applied to at least one of the predefined settings.

## Claims

### Claim 1

A video surveillance apparatus comprising:
a memory, the memory configured to store at least one predefined setting;
a processor in communication with the memory, the processor configured to:
compare a first parameter corresponding to a position of a video camera assembly configuration to a second parameter corresponding to the position of a modified configuration of the video camera assembly;
determine a difference between the first and second parameters; and
replace the stored at least one predefined setting with at least one modified predefined setting, the at least one modified predefined setting being based at least in part on the determined difference.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the first parameter includes at least one of a pan position, a tilt position, and a zoom position.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the first parameter includes an alignment indicator.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the stored at least one predefined setting is a stored plurality of predefined settings; and
the processor is further configured to replace at least substantially all of the stored plurality of predefined settings with a plurality of modified predefined settings, the plurality of modified predefined settings being based at least in part on the determined difference.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the memory is further configured store the first and second parameters.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein the at least one predefined setting is a target position.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the at least one predefined setting is a privacy zone setting.

### Claim 8 (depends on 1)

The apparatus of claim 1, further comprising at least one of a sensor and encoder in communication with the processor, the processor is further configured to obtain the second parameter from the at least one of the sensor and encoder.

### Claim 9 (depends on 2)

The apparatus of claim 2, wherein the second parameter includes at least one of a pan position, a tilt position, and a zoom position.

### Claim 10

A method of configuring a video surveillance system comprising:
storing, in a memory, a plurality of predefined settings;
storing a first parameter corresponding to an alignment of a video camera assembly configuration with a visual target;
obtaining a second parameter corresponding to the alignment of a modified configuration of the video camera assembly with the visual target;
determining, using a processor, a difference between the first and second parameters; and
replacing at least one of the stored plurality of predefined settings with at least one modified predefined setting, the at least one modified predefined setting being based at least in part on the determined difference.

### Claim 11 (depends on 10)

The method of claim 10, wherein the configuration is modified based at least in part on a relocation of at least a portion of the video camera assembly.

### Claim 12 (depends on 10)

The method of claim 10, wherein the configuration is modified based at least in part on a substitution of at least one component of the video camera assembly with at least one replacement component.

### Claim 13 (depends on 10)

The method of claim 10, wherein the first parameter includes at least one of a pan position, a tilt position, and a zoom position.

### Claim 14 (depends on 10)

The method of claim 10, wherein the first parameter includes at least one alignment indicator.

### Claim 15 (depends on 10)

The method of claim 10, further comprising replacing substantially all of the stored plurality of predefined settings with a plurality of modified predefined settings, the plurality of modified predefined settings being based at least in part on the determined difference.

### Claim 16 (depends on 10)

The method of claim 10, wherein the plurality of predefined settings includes a target position.

### Claim 17 (depends on 10)

The method of claim 10, wherein the plurality of predefined settings includes a privacy zone setting.

### Claim 18 (depends on 10)

The method of claim 10, wherein the plurality of predefined settings includes a surveillance pattern setting.

### Claim 19 (depends on 13)

The method of claim 13, wherein the second parameter includes at least one of a pan position, a tilt position, and a zoom position.

### Claim 20

A method of configuring a video surveillance system, comprising:
storing, in a memory, a plurality of video camera assembly position settings;
storing a first parameter corresponding to at least one of the plurality of video camera assembly position settings;
obtaining a second parameter corresponding to at least one of the plurality of video camera assembly position settings;
determining, using a processor, a difference between the first and second parameters; and
replacing the remaining stored video camera assembly position settings with at least one modified video camera assembly position setting, the at least one modified video camera assembly position setting being based at least in part on the determined difference.
