Capturing text insertions
Text insertion lets you insert or display text from a point-of-sale (POS) system on the
video display of the recorder. The text is saved and time‐stamped together with the
video. You can then search the text for specific video clips. The text is displayed during
playback.
The recorder supports POS and ATM text insertion via the UTC ProBridge accessory
connected to the RS-232 port on the recorder. This feature is currently only available
using the browser.
In both live view and playback, a camera set up for text insertion will display the video
with the POS text overlay.
See Figure 32 below for an example of a video image in live view with text insertion.
