HDcctv: Greater design flexibility
The transition to IP surveillance is well under way, as a growing number of security customers manage video from PCs, tablets, and smart phones.
Until recently, the only way to introduce megapixel (MP) video to an IP surveillance system required extending the local-site LAN to every MP IP camera mount.
Fortunately, there is now a new video interface for surveillance: HDcctv.
HDcctv provides the system designer a variety of new options for bringing MP IP surveillance to the internet, allowing the local-site IP LAN to remain confined to a secure control room.
HDcctv is the best thing that ever happened for megapixel IP surveillance. So says Todd Rockoff of the HDcctv Alliance. In this, the third of a four-part mini-series, he aims to “connect the dots between HDcctv and IP surveillance”.

HDcctv is different from both analogue CCTV and from IP transmission.
Because there is no global electrical interface standard for IP surveillance video, IP cameras can transmit MP video in an unlimited variety of formats.
V1.0 HDcctv transmits only HDTV signals: 720p25/30, 720p50/60, and 1080p25/30. Future versions of the standard will track the SMPTE HDTV formats to higher resolutions well beyond 10MP per frame.

Security installers have a new opportunity to conveniently bring high-quality video evidence to the internet via HDcctv-compliant DVRs.
This is the third in a four-part mini-series that connects the dots between HDcctv and IP surveillance.
HDcctv brings unprecedented flexibility to VSS design
The benefits of HDcctv interfaces are by now well understood. However, some designers seeking to employ IP networking as much as possible specify only IP cameras. These designers also stand to benefit from including HDcctv cameras.
HDcctv increases physical security and decreases the cost of even the most IP-centric systems by allowing a 300m home run to the control room before converting to IP in streamers.
If the customer can take advantage of the unadulterated live view coming over the HDcctv inputs, so much the better; this performance advantage comes at a cost savings.
The key question for the system designer is, "Where in this particular video surveillance system is the best place to convert each video signal to IP?"
The camera is not always the best answer, and HDcctv affords new options to the designer. The answer may differ among video channels in a single system.
Turn to HDcctv for high-quality, convenient, affordable MP IP surveillance
HDcctv is set to become the predominant video surveillance interface technology faster than anyone predicted. Because it is already so easy to integrate DVRs into IP video surveillance systems, the ready availability of HDcctv-compliant DVRs is accelerating the move to MP IP video.
The HDcctv Alliance is offering two HDcctv Retrofit seminars during IFSEC. The seminars are for security installers, because each existing CCTV customer is a sales lead for high-margin, non-disruptive upgrades of selected cameras to HD.
