HDTV network cameras

HDTV network cameras are a recent technology development that has gained enormous interest on the video surveillance market. As for megapixel, HDTV means excellent image detail, but in addition, a true HDTV network camera complies with industry standards which ensure excellent color representation, full frame rate and a 16:9 format. HDTV provides up to five times higher resolution than standard analog TV. The two most important HDTV standards are HDTV 720P and HDTV 1080P.

- HDTV 720P defines a resolution of 1280x720 pixels with high color fidelity in a 16:9 format using progressive scanning at 25/30 Hertz (Hz) — which corresponds to 25 or 30 frames per second.

- HDTV 1080P defines a resolution of 1920x1080 pixels with high color fidelity in a 16:9 format using either interlaced or progressive scanning at 25/30 Hertz (Hz) - which corresponds to 25 or 30 frames per second.

A camera that complies with the SMPTE standards indicates adherence to HDTV quality and should provide all the benefits of HDTV in resolution, color fidelity and frame rate.

HDTVs are based on square pixels — similar to computer screens, so HDTV video from network video products can be shown on either HDTV screens or standard computer monitors. With progressive scan HDTV video, no conversion or deinterlacing technique needs to be applied when the video is to be processed by a computer or displayed on a computer screen.

HDTV means that the image is very pleasing to eye, with full frame rate video and excellent color representation. It provides a wide-screen 16x9 image, perfect for modern screens and TVs. The fact that true HDTV network cameras comply with key industry standards means that image quality is guaranteed to a higher degree than for many megapixel network cameras. HDTV network video is superb for applications where full frame rate is prioritized.

Airports, casinos, city surveillance, passport controls are some examples where HDTV network video is a perfect solution to achieve image usability.
