HD is a standards based format governed by the Society of Motion Picture and Television Engineers (SMPTE) that not only guarantees resolution (720P, 1080i or 1080P) but also the 16:9 widescreen format, frame rate and color fidelity of the video. The most common standards are: SMPTE 296M or HD 720P which uses 720 scan lines and a refresh rate of 30 progressive scans per second, SMPTE 274M or HD 1080 using 1,080 interlaced (1080i) or progressive (1080P) scan lines and a refresh rate of 30 or 60 Hertz which corresponds to 30 or 60 frames per second.

Important difference between HD & Megapixel

Megapixel strictly applies to one part of the image: the number of pixels in the field of view. Megapixel has no meaning in terms of frame rate, aspect ratio or color fidelity performance of the video. Just because a camera has a higher Megapixel count does not necessarily mean it will provide higher usable video quality than a camera with a lower Megapixel count running in HD-SDI.

High Definition Surveillance

To guarantee you will have real time Full HD Video it is a MUST that HD EX-SDI Cameras are connected to HD EX-SDI DVRs.

Is there a downside to Recording in Full HD?

EX-SDI cameras and DVR's will provide the best live and recorded video available anywhere, but because of the far greater detail being captured by EX-SDI systems, additional storage capacity will be necessary. Most projections suggest that EX-SDI Systems require about 3x the HDD storage capacity of regular Analog PC DVR Systems. Plan accordingly and grab an extra 1TB hard drive or 2TB hard drive with your system if you're going to be putting these systems through their paces.
