command is received, the camera will begin to record. This is indicated by the blinking red LED
(1x/second).
If you are streaming, the video player will show the preview of what is being captured.
3. Once you are recording, you can tag a video file. To tag the clip being recorded, use the Web
Programmable HTTP/XML interface to send a tag command to the STREAM (<ip
address./api/record/tag).
A tag is a time marker on a clip, similar to a bookmark in a document.
Tags may also be used by other future editing features.
Record Modes
The STREAM supports 3 Record Modes through the record interface commands. A complete discussion of
what each Record Mode does as well as guidelines for selecting the right Record Mode is provided in
Understanding the STREAM Video Record Modes
, below
.
Clip records video like a standard video recorder. Once you start recording, video is captured continuously
until you stop recording or the Micro SDHC card is full.
Loop records a short clip every time you send a tag command. The saved clip(s), referred to as a loop,
includes action immediately before you send the tag command, as well as action immediately following.
Loop & Forward keeps no video until you send a tag command for the first time. Then a loop is captured
and all action following that first tag is captured as well.
To set the Record Mode, use the Web Programmable HTTP/XML interface.
When you use the Loop method, looptime determines the length of the saved video loops. When you use the
Loop & Forward method, loopforwardtime determines the length of the saved video . The actual length of a
saved loop is never less than the looptime or loopforwardtime, but it can be longer. See
for additional information about how the STREAM determines how much video to
save in order to ensure that you capture the action immediately before and immediately after each tag.
Record using the Wi-Fi interface
The STREAM allows you to control recording and set tags on a video clip without touching the recorder
through use of the Web Programmable HTTP/XML interface over Wi-Fi. This allows you to place the STREAM
in out of reach places yet still control it. The STREAM does not have a remote control, but allows integrators
the ability to create a remote control capability through the Wi-Fi interface.
Record still photos or capturing MJPEG’s
Still Photo
To save a still photo to the Micro SDHC Card, there are two commands that may be used in the Stills
interface.
1. The capture.jpg (<ip address>/api/still/capture.jpg command will save a still photo to the Micro SDHC
card in the Snapshots directory and will return the jpeg to the calling interface.
2. The save command (<ip address>/api/still/save command will only save a still photo to the Micro SDHC
card.
MJPEG Interface
In addition to the still photo interface, an MJPEG interface exists on the STREAM. This interface allows the user to
capture a single MJPEG or to start and stop a continuous stream of MJPEG’s. Please see the Web Programmable
API for details on the MJPEG interface.
