HD-SDi 1080P

Highest Definition Possible Over Coax

HD-SDI Technology: The Future of CCTV

HD-SDI (High Definition Serial Digital Interface) is a high definition digital video technology that transmits 1080P video quality over coaxial cable. The HD-SDI technology transmits uncompressed video signal to the DVR. Our HD-SDI cameras offer true megapixel image quality without the complexity of network IP cameras.

HD-SDi Security Camera Basics

HD is a standard 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.

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 real time 1080p HD Video, connecting your HD-SDI Cameras to an HD-SDI DVR is an absolute mus

Is there a downside to Recording in Full HD?

HD-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 HD-SDI systems, additional storage capacity will be necessary. Most projections suggest that HD Security Camera Systems require about 3x the HDD storage capacity of regular Analog 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.

Best of Both Worlds

HD-SDI cameras allow customers with an existing analog infrastructure to enjoy the paramount image quality of megapixel, without the hassle of converting the entire security system to a network security solution.

No Compression…

HD-SDI contenders have also touted zero image compression as a key winning point over their IP-based, HD-CVI and HD-TVI counterparts, for all CVI, TVI and IP systems the footage is compressed (like when you send an email with a file so big you need to compress it in a Zip file to send it out) . Raw data is indeed delicious, just like how fresh vegies and sushi are infinitely tastier than lesser, processed foods.

This footage was taken at exactly the same time, you can see the IP system missed the taxi and the motorcycle while the real time uncompressed HD-SDi system caught everything. No latency. No delays.
