When you zoom an image, you are enlarging the pixels in the frame. So in many cases the enlarged picture does not reveal detail. It reduces clarity and looks blurry on the evening news when they try to identify the suspect.
Mega pixel resolution helps mitigate this situation, assuming the field of view the camera is deployed to view will have enough resolution to pull up the desired detail when enlarged.
SG Digital’s technology is based on coaxial cable to transmission HD-SDI signal. SDI signal is serial data interface that doesn’t cause delay or buffer during transmission (unlike the existing IP cameras).
SDI refers to a family of video interfaces standardized by SMPTE (The Society of Motion Picture and Television Engineers), an international professional association, based in the United States of America, of engineers working in the motion imaging industries.
High-Definition Serial Digital Interface (HD-SDI) defines digital video interfaces used for broadcast-grade video which provide a nominal data rate of 1.485 Gbit/s. These standards are used for transmission of uncompressed, unencrypted digital video signals (optionally including embedded Audio and/or Time Code) within television facilities; they can also be used for packetized data. They are designed for operation over short distances (less than 300m. with coaxial cable); due to their high bitrates they are inappropriate for long-distance transmission. Previously SDI and HD-SDI were only available in professional video equipment; various licensing agreements, restricting the use of unencrypted digital interfaces to professional equipment.
The various serial digital interface standards all use (one or more) coaxial cables with BNC connectors, with a nominal impedance of 75 ohms. This is the same type of cable used in analog video setups, which potentially makes for easier upgrades (though higher quality cables may be necessary for long runs at the higher bitrates).

Two ways of connection Megapixel camera either HD-SDI (Box Type) or PCI Card.
Transmission distance varies depending on coax cable specifications
Built-in DIO Sensor (Sensor in 2 channels), simply sensor cable can connect with Megapixel camera. The signal goes through coaxial cable with Video data.(Easy/Economy installation)
