Linear
Video Modulator for Access Cameras
The Model DPDM-1 Digital Modulator converts
any baseband NTSC video and audio signal to a selected UHF or Ultraband
CATV channel. A quartz crystal reference oscillator and PLL circuitry
ensure drift-free performance.
The modulator can be used to convert
video signals from Linear's access control systems to UHF or CATV
signals that can be viewed on a standard television set at the installation.
Features:
• Converts the access system's camera video signal to a UHF
or CATV channel television signal
• A quartz crystal reference oscillator and PLL circuitry
ensure drift-free performance
• A television is tuned to the modulator's programed channel
