Key features:

  • 1/3″ Colour CCD DSP Day/Night Camera
  • Super-High Horizontal Resolution of 520TV Lines
  • 24v AC and 12 to 15V DC dual power operation (VCC-4795P)
  • 220 to 230V, 50Hz operation
  • Auto-tracing or manual white balance selectable (Slide SW)
  • Built-in high-speed electronic shutter
  • Internal synchronisation, line-lock capability
  • Built-in electronic iris for indoor use
  • High Sensitivity – Minimum illumination of 0.45 lux (F1.2 Colour Mode) or 0.01 Lux (F1.2 B/W Mode)
  • Two Types of backlight compensation: Multi-Spot and Centre-Zone metering

A two-in-one solution: a colour camera during the day, a high-sensitivity B/W camera during the night.
A colour camera, which captures objects in vivid colours in day-light, becomes a high-sensitivity B/W camera during the night and provides tiny details even in dark corners. A day/night camera is a two-in-one solution.

Multi-spot metering system:

Luminance is measured in 64 separate areas for optimum backlight compensation even for peripheral and moving objects; features selectable normal and high modes.

Centre-Zone metering system:

Luminance measured at centre and automatic lens aperture adjustment enable a clear image even when backlit.
