to store them locally on the device and

to transmit them slowly based on a policy which indicates an acceptable amount of bandwidth to utilize; and

a means for deriving more compact representations of the event which can assist in determining if the event is of further interest.

2. A system for transmitting a compact representation of an event of interest comprising:

a transmission channel coupled to

a first network interface circuit and to

a second network interface circuit, the first network interface circuit coupled to

a circuit comprising a processor controlled by software to execute the following computer-implemented steps;

to determine if the compact representation cannot be immediately transmitted,

to store the compact representation locally and

to retry transmission at a later time; and

at a server coupled to the transmission channel,

to receive an https request;

to open an https server session;

to connect between an https client and an https server; and

.

to receive and store the compact representation.

3. A point of recordation terminal apparatus comprising:

digital logic or

a circuit comprising a processor coupled to storage controlled by software encoded in the storage to execute at least one of the following computer-implemented steps;

to open an HTTP client request to POST a reference;

to change configuration of other circuits in the terminal;

to transmit immediately when directed;

to store a reference if immediate transmission fails, and

to specify all data should be recorded and transmitted immediately for a limited period, wherein a reference is a compact representation of a video frame and meta-data associated with an event of interest.

4. A point of recordation terminal apparatus comprising:

an asset &

event capture and storage circuit, coupled to

a reference selection &

storage and meta-tagger circuit, coupled to

5. A method for operation of point of recordation terminal apparatus over a low bandwidth and unreliable transmission channel,

the method comprising

capturing an event of interest, wherein capturing an event of interest comprises the following processes

determining a start of an event of interest;

recording and storing video frames and meta-data associated with the event of interest as an asset;

deriving a compact representation of the event of interest as a reference;

recording and storing the reference to the event of interest;
