Apakah yang dimaksud dengan SONY Super HAD?

1 Juli 2010

SONY CCD cameras sold in the market nowadays are almost all using Super HAD technology. Super HAD provides 2 times of better sensitivity and 6 db better smear rejection ratio than the formal traditional type of CCD. Two micro lenses on top of each photo diode are able to collect more photon from incoming light  than the old CCD made by SONY and any other maker. 
Panasonic believes that its that its new 37 series is as good as SONY's Super HAD, and its 39  series is also as good as SONY EX-View on visible light zone.
Alpha B and K series cameras now are using mainly Panasonic CCD  for the best color rendering and good  dynamic range.

Compared to Super HAD, Sony Ex-view CCD Do have 4 times of better sensitivity on near infrared zone ( 800~ 900 nm).  However, if the users use it properly,  it will be excellent for night vision. If not properly, it will became a draw back because the infrared will cause color distortion and blurred image due to basic physics that infrared focuses on deeper location and cause hologram image especially if the certain lenses are used.

MJPEG, MPEG4 or H.264 which one is better?
Selecting the proper imaging technology up front will be one of your most important decisions you will face designing and implementing your network video project. When considering compression options for network video solutions, the following video related issues should be reviewed and carefully considered. Minimum Resolution Image Quality Minimum and Maximum Frame Rates (FPS) Number of Cameras (Scalability) Storage Requirements Available Bandwidth Overall Latency (time difference between live and displayed video) Budget The compression logic used in both MJPEG, MPEG4 and H.264 are beyond the scope of this white paper. Suffice it to say that MJPEG, MPEG4 and H.264 compression algorithms are the most common forms of video compression currently used in the network video industry.

960H Resolution For the Best
960H refers to a new class of advanced imaging sensors that capture more pixels per target object to provide a maximum of 720TVL the highest available image quality for the PAL and NTSC standards. This new technology serves as a bridge between standard resolution and high definition solutions, making 960H the best option for ultra-high resolution video without switching to IP.
