	External synchronization		Function to synchronize the timing of cameras' motion when multiple cameras are used simultaneously. Composite Sync. of sync. signal generators and CVBS signal of cameras are applied for the timing synchronization.
	Gamma correction		Function to correct video signal to earn proper contrast on monitored image
	BLC (Back Light Compensation)		Function to adjust exposure of silhouetted subject by bright light behind
	Defog		Function to improve image quality captured under poor weather condition such as fog, rain, snow, etc.
	Minimum illumination		Value (lx.) to describe how dark the camera can capture usable image
	Imaging system		Type of filter systems adapted by color camera sensors (Primary color system: high color reproducibility, Complement color system: high sensitivity)
	Horizontal resolution		Value (TVL) to describe image fineness the camera can provide to monitor in horizontally (The higher, the finer)
	Cell size		Value to describe size of unit pixel of image sensor (The bigger, the better in sensitivity and the less saturation output)
	Communication function		Function to allow remote operation of parameter setting change or OSD setting for RS232 or RS485 communication method
	Day/Night function		Function to provide color image under sufficient illumination & B/W image under low-light condition automatically, manually
	One-cable system		Transmission system to send video signal & receive power supply via 1 coaxial cable to facilitate cable routing
	Motion detection		Function to detect moving object and provide addressed task in detection
	Noise reduction		Function to reduce noise from the image captured in high gain condition (2D: perform within 1 frame, 3D: perform by using the images before and after)
	White blemish correction		Function to automatically correct white pixels
	Privacy masking		Function to cover addressed area in captured image for privacy protection purpose
	FL (Flickerless)		Function to reduce flicker phenomenon from images captured under commercial power frequency 50Hz
	White balance		Function to optimize color reproduction in accordance with the lighting condition
	Mirror image		Function to obtain horizontal and/or top-bottom inverted image
	WDR (Wide Dynamic Range)		Function to stabilize contrast of light and shadow to provide clear and usable image when object has extremely bright and dark parts at once
	AE mode (Automatic Exposure mode)		Function to automatically control shutter speed to provide appropriate and stable brightness level to image
	AGC		Function to automatically control gain of amplifier to provide visible image under low light condition
	HD-SDI		HD-SDI is the abbreviation of High Definition Serial Digital Interface, which delivers high quality live HD video over coaxial cable with exceptional resolution and image detail. HD-SDI technology delivers image quality that is far superior to analog CCTV that is easy to install and integrate with existing CCTV systems. (e.g.: WAT-2200, WAT-30HD)
	HD-TVI		HD-TVI is the abbreviation of High Definition Transport Video Interface which is based on traditional coaxial cable for video transmission. It supports 720P/1080P video signal over long distance up to 300 meters and provides you a cost-effective video surveillance solution. (e.g.: WAT-2300)
	HSBLC		Function to reduce reflection of light by masking the part(s) containing strong light to improve visibility of image
	MGC		Function to fix gain of amplifier
	OSD		An on-screen display(OSD) is a control panel on a monitor that allows you to select viewing options
	S/N		Value (dB) to describe the strength of video signal compare to the back ground noise
