The compact camera HIVISION HI-9W428is equipped with Sony Super HAD II CCD and modern Sony Effio-E DSP. It provides video with resolution of 650 TVL, featuring natural colors and high S/N ratio. The Sony Super HAD CCD II image sensor is a further improvement of the technological solutions used in Super HAD CCD. The new features include larger number of pixels and a greater sensitivity.
The influence of ATR function (on the right) on readability of the image (A - in the brightest area, B - in the darkest area)
Focal length and focus adjustments can be performed after unscrewing the front part of the housing (the border is the red seal). After the adjustments, the rings should be locked with the dedicated screws. This area also contains 5-button OSD keypad.
The camera can be set in the desired direction by releasing the screws of the two-part bracket. Due to the size and weight of the camera, the solution is much more reliable than a ball joint and ensures high stability of the selected position.
The OSD menu contains the following settings:

sharpness
white balance
shutter speed
AGC
BLC
Day/Night function
DWDR (digital wide dynamic range)
motion detection (4 zones with sensitivity levels)
8 privacy masks

The main functions:
IRC - mechanically switching IR filter. The filter is used in Day-Night cameras. In color mode the filter cuts IR spectrum that would distort actual colors.
OSD - displays the camera menu on a display screen, eliminating the need to implement a lot of switches/potentiometers on the rear panel of the camera.
ATW (Auto Tracing White Balance) - continuously adjusts camera color balance in accordance with any change in color temperature, allowing the camera to capture color as seen by the human eye.
AWB (Auto White Balance) - white color is automatically detected and used for camera color balance. It is suitable for environments with small changes of color temperature, the other ones require to use the above listed ATW function .
Anti-CR (Anti-Color Rolling) - reduction of rotating color changes caused by flickering sources of light (e.g. fluorescent lamps), which cannot be eliminated by external synchronization with the power network (usually due to powering the camera with DC power source).
AWC (Auto White Color/Circuit) - adjustment of the white balance to a "standard" white area/object. The calibration should be repeated when the lighting conditions have been changed.
AGC (Automatic Gain Control) - maintains a constant output level, increasing the signal to noise ratio. The picture is more clear but less natural. Without this function (AGC OFF) the image is generally more natural, but more grainy.
EE/AI (Electronic Shutter) - in EE mode it adapts the exposure time to the light intensity. In AI mode, the exposure time is constant (1/60 or 1/50 s) and level of incident light intensity is regulated by auto-iris lens (Auto Iris).
BLC (Backlight Compensation) - automatically adjusts the level of bright light in order to provide more detail in dark areas. A good example is the image a human's face in the background of the sun shining from behind.
HLC (High Light Compensation) - masks extremely bright areas such as car headlights.
Privacy zones - masking areas that should be not visible.
AES (Auto Electronic Shutter) - used to adjust the the exposure time to the light intensity (mostly with lens without AI function).
DNR (Digital Noise Reduction) - circuit and/or algorithm which reduces noise, thus providing a higher signal to noise ratio. 3D DNR compares subsequent image frames. If, as a result of this analysis, it finds a difference between the images resulting from noise, it removes the very small grains, replacing them with average values.
Sense-Up - enhancement of camera sensitivity by slow shutter speed. Cameras with Sense-Up function can be used in very low
