micro-Gemini-2

Video Link Expander

Micro-Gemini-2 is the simplest way to add an extra camera to ultra-covert surveillance links and retains all the key features of the standard Gemini range including full colour operation, fast update rate, on-screen display and by-pass on power-down.

Micro-Gemini-2 is a miniature video link expander that is easy to conceal when carrying out highly covert surveillance. This unique device is simple to operate and install and offers more discretion when size, weight and low power consumption are prime considerations.

The Micro-Gemini-2 encoder combines two independent video inputs together to give a single field-multiplexed output, which is compatible with most real-time video links, including coax, fibre optic, analogue wireless and even some digital wireless links. At the receive site, the signal is decoded back onto two separate outputs by a micro-Gemini-2 or standard Gemini-2 /4 decoder.
