    Several HD video overlay devices are offered, including the GeoStamp HD, which overlays GPS latitude, longitude, heading, speed, altitude, date, time, and depth onto AHD, HD-TVI, and HD-CVI (720p/1080p) video sources. The VideoStamp HD allows user-defined text overlays on similar HD video inputs, while the VideoStamp Keyboard HD enables text input via a PS/2 keyboard for video overlay. For commercial applications, the PostMark HD integrates with cash registers and POS terminals to overlay transaction data onto security camera feeds. Beyond HD video solutions, the DTMF-8 DTMF Decoder provides remote control capabilities for up to eight devices or relays using touch tones from a radio or other audio source. This decoder supports four operational modes and includes password protection, storing all settings in non-volatile EEPROM memory. The product line also includes standard definition OSD, RS-232, GPS, and POS text inserters, along with various DTMF encoders and DVR solutions.
