HD-SDI(High Definition-Serial Digital Interface signal)
The digital video interface with 1.5 Gb/s transfer rate is standardized in SMPTE 292M. It supports 1080i /59.94
signals and can transmit signals up to 208M (stable distance 145.6M) when coaxial cable is connected. The
advantages of HD-SDI include no signal delay, video and audio reporting, and time code signals.
* The 3G-SDI standardized in SMPTE 424M supports transfer rate of 3.0 Gb/s and 1080p/60 signals. It can
transmit signals up to 141M(stable distance 98.7M) when connecting coaxial cable.
w
HDMI(High-Definition Multimedia Interface)
The high-speed transmission standard that can integrate and transmit digital video and voice signals. It is mainly
used in home appliances. The transmission distance is about 10 ~ 15M.
w CVBS(Composite Video Blanking and Sync)
The analog video output signal used before Digital. The two-color difference signals are overlapped on one
channel in the luminance signal. Basically, the deterioration is severe, and the image quality is not good. The
longer the transmission distance, the more noise, and the lower picture quality.
w
VISCA
The communication standard made by SONY to control PTZ camera.
w
PELCO D/P
The communication standard using CCTV to control PTZ camera.
w
ONE PUSH
This function adjusts the color based on the white paper in the center of the screen to adjust the white balance.
It is distinguished from the AUTO function that automatically adjusts the closest color based on the displayed
image, or the ATW function that reproduces the original color of the subject, excluding the influence of ambient
light. The AUTO or ATW function can achieve the proper white balance, but it is recommended to use ONE PUSH
to adjust more accurately.
w IRIS
In the camera, IRIS refers to the aperture. Iris is an important factor in determining depth, which improves image
quality and depth so that you can see both distant and near objects clearly.
w
GAIN
It is a function to electronically amplify the signal when the light source is not illuminated enough, and the image
signal level is not enough. It is used when there is insufficient light on screen even if all iris is open. However,
since the amplification is forcibly amplified by using the electrical characteristics, noise may occur and may be a
deterioration of image quality.
w
Shutter Speed
This function sets the opening time of the shutter. Only when the shutter is open, the light is transmitted to the
image sensor and the image is taken. For example, the lower the shutter speed is, the more vivid the dynamic
image can be.
w Digital ZOOM
This function enlarges a part of image data by digital processing method and obtains zoom effect. Because it is
