The VGA converter by Videocomponents, type VGA1-HR, is designed to convert analog video signal in FBAS format (Composite Video) via a BNC connector into a digital VGA signal, which can be connected to modern monitors, projectors, or displays with a 15-pin D-Sub socket. The device is specifically designed for use in surveillance systems, security technology, or for connecting older video sources to current display devices. It enables the use of analog cameras or video devices operating via BNC interface with modern displays that support VGA inputs.

Applications

The converter is suitable for applications where analog video from older systems, for example from surveillance cameras or VCRs, is to be displayed on an LCD or TFT monitor. It is frequently used in security installations, small surveillance centers, or for reusing existing analog video sources. The conversion occurs without loss of image quality within the specified resolution and enables clear display on modern display devices.

Functions and Equipment in Detail

The converter features an input for analog video in FBAS format (Composite Video) via a BNC connector. The signal is received at a level of 1 Vss with an impedance of 75 Ohm. Supported television standards are PAL and NTSC, enabling use with a wide range of analog video sources worldwide. At the output, the signal is converted into VGA format and delivered via a 15-pin D-Sub socket. The output resolution is 1024x768 pixels at a refresh rate of 75 Hz, sufficient for smooth display on compatible monitors.

Technology Explained Simply

The device converts the analog composite video signal, entering via a single BNC connector, into a digital RGB signal, which is then transmitted to a display via the VGA connector. The conversion is performed internally by a signal processor that decodes the analog signal and converts it into the corresponding color and synchronization signals for VGA. The resolution of 1024x768 pixels corresponds to the standard XGA, available on many monitors and projectors. The frequency of 75 Hz ensures flicker-free display, suitable for operation in surveillance systems or during prolonged viewing periods.

Compatibility and Accessories

The converter is compatible with analog video sources operating via a BNC connector and supporting the television standards PAL or NTSC. At the output, it connects to devices featuring a VGA input (15-pin D-Sub socket), such as LCD monitors, projectors, or older computer displays.

Mounting and Installation

Installation is performed by directly connecting the analog video input (BNC) to the video source and the VGA output (15-pin D-Sub socket) to the display. The device requires an external power supply of 12 V DC, connected via a corresponding connector. Physical mounting, due to its compact dimensions (length 100 mm, width 75 mm, height 25 mm), is typically done on a surface or inside an enclosure. The weight is 300 g, enabling easy handling.

Advantages in Operation

Using the converter allows existing analog video sources to be connected to modern display devices without requiring a complete system replacement. The conversion occurs without visible image distortions within the specified resolution. The operating voltage of 12 V DC is commonly available in many surveillance systems, facilitating integration into existing infrastructures. The device is compact and lightweight, allowing flexible placement. The warranty is 90 days, and the device is supplied as a demonstration unit.
