Video Modulators

These modulators take a baseband video (NTSC) and audio signals and convert them to a modulated radio frequency signal. (A TV channel.)

Baseband video is what comes out of your VCR "video out" jack and is normally a female RCA (or "phone") jack. It carries only one video signal...and no sound. There is usually one (mono) or two (stereo) line-level audio RCA jacks associated with a video jack.

RF jacks are normally "F" connectors and can carry multiple channels of information, with each channel containing video and audio (even MTS stereo) signals. The coax cable that brings cable or off-air TV into your home is an RF cable.

Modulators are a key piece of hardware in any video distribution system as they allow you to create your own TV stations from local sources such as your VCR, LaserDisk, DVD, or CCTV cameras. You can then "combine" these new TV stations with your existing cable or off-air stations and easily distribute all signals throughout your home on a single coaxial cable.

Finally! The modulator our contractors have been screaming for! If you have ever installed a modulator at the headend for CCTV cameras, you know that there is really no clean way to do it. All other modulators are either a free-standing box, a box that wants to sit on a shelf, or an expensive module that goes into a structured wiring panel. Now simply screw this module to the backboard or to the wall inside the structured wiring panel and...voila! It stays in place, looks clean, and allows simple hookup, setup, and years of reliable service. Digital RF Single-Channel Modulator: Simple channel setup Wide Channel Range: UHF 14-78 / Cable 65-135 (Excluding 95-99) Adjustable video level. Conviently mounts to plywood or wood-backed enclosures with four screws. Wall-wart type power supply included. 12VDC @ 250mA Perfect for modulating video feeds from cameras at your head-end!

Most common A/V devices are gaming systems and DVD players that take up space around your TV. Conventional modulators, usually set on top of your TV, can add to this disorder. Unlike other modulators, the MINI is compact; it reduces the clutter around your TV by easily mounting on your wall or entertainment center. The MINI was designed to be in-line, so that it can hang or be mounted on a vertical surface and out-of-sight. After first installation, there is no need to access the MINI again. It features automatic signal detection and automatically switches between A/V sources when a signal is detected.
