3. A system according to claim 1 and further comprising a database, wherein said logging apparatus is operative to associate any portion of said digitally formatted input substantially in real-time to receipt of said portion with any of an input channel datum, a time datum, a date datum, a non-ambient characteristic datum, and a trigger datum, and maintain any of said data in said database.

4. A system according to claim 1 wherein said logging apparatus is operative to selectively control any of said input devices to provide analog input therefrom.

5. A system according to claim 1 and further comprising:

at least one cyclic buffer associated with at least one of said input devices, wherein said logging apparatus is operative to;

detect a non-ambient characteristic associated with any of said digitally formatted input;

cyclically store any of said digitally formatted input in said cyclic buffer prior to detecting said non-ambient characteristic; and

provide said any of said digitally formatted input stored in said cyclic buffer to said digital storage apparatus subsequent to said non-ambient characteristic being detected.

6. A system according to claim 5 wherein said digitally formatted input is digitally formatted video input and wherein said non-ambient characteristic is a non-ambient motion characteristic associated with any of said digitally formatted video input.

7. A system according to claim 5 wherein said digitally formatted input is digitally formatted audio input and wherein said non-ambient characteristic is a non-ambient sound characteristic associated with any of said digitally formatted audio input.

8. A system according to claim 5 wherein said logging apparatus is operative to detect said non-ambient characteristic associated with any of said digitally formatted input converted from said analog input received from said at least one input device associated with said at least one cyclic buffer.

9. A system according to claim 5 wherein said logging apparatus is operative to detect said non-ambient characteristic associated with said digitally formatted input converted from said analog input received from any of said input devices other than said at least one input device associated with said at least one cyclic buffer.

10. A system according to claim 1 and further comprising:

at least one detection device operative to detect a non ambient characteristic and provide a signal subsequent to and in connection with detection of said non-ambient characteristic; and

at least one cyclic buffer associated with at least one of said input devices, wherein said logging apparatus is operative to;

receive said signal from said detection device;

cyclically store any of said digitally formatted input in said cyclic buffer prior to receiving said signal;

provide any of said digitally formatted input stored in said cyclic buffer to said digital storage apparatus subsequent to receiving said signal.

11. A system according to claim 10 wherein said non-ambient characteristic is a non-ambient motion characteristic.

12. A system according to claim 10 wherein said non-ambient characteristic is a non-ambient sound characteristic.

13. A system according to claim 10 wherein said non-ambient characteristic is the presence of a transmitted signal detected within a predefined detection region associated with said detection device.

14. A system according to claims 5 or 10 wherein:
