The FG-50HD device links point of sale terminals (POS) with CCTV cameras to produce a continuous overlay of transactions superimposed on the video output. The FG-50HD character generator acts as a looping device, with CCTV video signal input and output. The Cash Register/POS data is overlaid on the video image provided by the video output.

The device can be used in CCTV systems of the following video standards: PAL, AHD, HD-CVI, HD-TVI. In the case of HD standards, it supports both 720p and 1080p resolutions.

The device can provide additional security against fraudulent practices (such as non-registered transfers of products, registering inappropriate items, etc.). In addition, FG-50HD can operate in terminal mode and display all character strings received from the POS terminal or other device with RS-232 or RS-485 interface, such as readings of weight, temperature etc.

Connecting the FG-50HD M1725 text inserter to a cash register/POS printer:
To connect the device to a POS printer, one needs RS-232 to RS-485 converter SNIF-42 M1721. SNIF-42 M1721 monitors ("sniffs") RS-232 transmission without any risk of changing the original data. This is particularly important in the case of cooperation with POS printer, which does not tolerate disruption or errors in data exchange. Therefore, it is not recommended the use other RS-232 to RS-485 converters.
