Universal 4CH Video Color Quad Multiplexer

The Universal 4CH Video Color Quad Multiplexer combines up to four analog CCTV camera signals onto a single monitor. It is designed for installers and small-business owners who need real-time viewing of multiple cameras without a dedicated DVR. The unit includes a remote control and a 1A power adapter for immediate deployment.

Analog Camera Display Upgrade

This multiplexer replaces the need for separate monitors or manual switching between cameras. The jump is worth it when an existing analog system uses more than one camera and the operator wants simultaneous quad, dual or single-channel views with on-screen titles, time and date stamps. It does not support IP or HD-SDI cameras, so buyers needing digital camera integration should look elsewhere.

Simple BNC Installation

Installation requires connecting each camera to one of the four BNC inputs and the monitor to one of the two BNC outputs using standard 75 ohm coaxial cable. The DC12V 1A adapter powers the unit directly. Common issues include mismatched NTSC or PAL settings causing rolling pictures, incorrect termination leading to ghosting, and loose BNC connectors interrupting the video lost alarm.

Questions about this item

What BNC connectors does the 4CH multiplexer provide for camera inputs and monitor outputs?

Four BNC inputs accept analog cameras at 1.0 V p-p 75 ohm, and two BNC outputs feed monitors at the same 1.0 V p-p 75 ohm level.

How do you switch the unit between NTSC 60 fields per second and PAL 50 fields per second, and what mistake do installers make?

Use the on-screen menu to select NTSC 720 x 480 or PAL 720 x 576; the common error is leaving the default standard while cameras use the opposite format, causing no picture.

When should the included 1 A power adapter be replaced, and what voltage must the new unit supply?

Replace the adapter if the multiplexer loses video or reboots; any replacement must deliver DC 12 V at 1 A to match the working voltage spec.
