1 PRODUCT OVERVIEW
The EZ 425W2 outdoor camera is designed for applications with low lux
environment. The integrated powerful IR illumination with 36 IR LED allows the
camera to provide low noise video signals also in distances > 15 metres. Enhanced
features are – among others – WDR (enhanced dynamic area), 8 privacy zones,
adjustable backlight compensation and highlight compensation.
1.1 FEATURES
High resolution CCD / DSP technology (600 TV lines)
2,8~12mm varifocal lens with easy adjustment without opening camera
housing
Day/night function with adjustable switch delay and switch thresholds
On-screen menu setup with keys at the back of the camera
Picture adjustment for brightness / contrast / colour
8 adjustable privacy zones
Enhanced dynamic area with WDR, BLC, HSBLC
Backlight compensation with adjustable zone and gain setup
NOTE: This camera doesn’t provide an IR cut filter. Under some conditions, this may cause colour
shifts in colour mode (e.g. green leaves appear some blue), if there is a high infrared portion
in daylight. This is a normal behaviour of this class of camera and no engineering deficiency.
