It works on your existing wiring infrastructure (saving you money), you can combine SD and HD cameras for a hybrid solution (easing the transition to HD) and most importantly it opens your system to the world of apps, for unsurpassed versatility, analytics and functionality (rocketing your ROI).
Wide Coverage + High Resolution
An HD Megapixel camera delivers 2.5 times higher resolution video compared to a conventional analog CCTV system.
The factors that contribute to the explosive growth of HD Mega Pixel cameras are their abilities to provide wider coverage and exceptional detail. A 2-megapixel camera can cover an area six (6) times larger than a VGA network camera. With a 2-megapixel camera compensating for six (6) VGA cameras, the installation costs can be significantly reduced.
An HD Megapixel camera not only provides more image detail but wider coverage or field of view. VideoUnion’s HDcctv camera supports a wide screen’s aspect ratio of 16:9, which has wider coverage compared to an analog camera with an aspect ratio of 4:3.
Exceptional Detail
When monitoring an area, a megapixel camera provides superior image quality compared to a standard resolution camera. As illustrated above we compare a VGA 1.3MP and 2MP image. The license plate in the 2MP image can be easily identified, but not in the case of VGA resolution. Thus, in applications where accurate identification is required, a megapixel camera image can provide detailed information that is obscure when using a VGA camera.
Cost Saving
With higher resolution and wider coverage, VideoUnion’s HDcctv Solution will greatly reduce the number of cameras that need to be deployed. This will translate into lower initial investment and the long-term maintenance cost.
PTZ
VideoUnion’s megapixel cameras are equipped with electronic pan/tilt/zoom (PTZ) capabilities that enable users to instantly move to a target region instantly for close-up shots by simply clicking on the video feeds on their screen rather than physically moving the camera. With PTZ, bandwidth and CPU can be used more efficiently because only the image of the target region is encoded and transmitted.
HD-SDI is the easy way to HD.
Unlike Megapixel IP or Analog, HD-SDI provides a reliable infrastructure on which to deliver HD (Megapixel) video without calculating bandwidth requirements, eliminating all the risks of putting the cameras on a computer network and using your existing coax cable installations.
Not Mega Pixel or IP
This is a third method of video transmission. HD-SDI (High Definition Serial Digital Interface) allows you to install 1080P (2 MP) cameras without setting up a network or calculating bandwidth. HD-SDI keeps the cameras off the network and on secure coax (closed system) just like analog. It’s been in the Broadcasting Industry for over 20 years and is still used today. Most sporting events and news, broadcast in HD, use HD-SDI.
Best of IP and Analog
Although HD-SDI operates on a closed system, it’s still a part of the IP revolution that is taking place in the CCTV Industry. HD-SDI incorporates the best of a closed CCTV system with the capabilities of IP. Between the camera and DVR is coax, but after the DVR or encoder it’s all IP. Your customer’s cameras are kept off of their computer Network, but still have the ability like IP, to stream video over a Network or the Internet. An HD-SDI installation is as easy as an analog installation. HD-SDI = Easy HD.
How does it Work ?
HD-SDI sends an HD digital signal over coax or fiber. The digital signal is uncompressed, with no packetization. The signal is received by the HD-SDI DVR and then compressed into H.264. Once it’s H.264, it can then be streamed over a network or the Internet. HD-SDI is an organic stream of 1080P and has not been processed in anyway before it reaches the DVR.
HD-SDI Highlights
- HD-SDI and analog can be mixed in an installation. Hybrid DVRs are available.
- No need to set up a network. HD-SDI cameras are not on a network. HD-SDI cameras are on secured coax or fiber. If the network goes down, cameras are still running and recording.
- HD-SDI is great for analytics since it offers an organic signal that has not been compressed. Accuracy is greatly improved since there are no lost frames or distortion in the picture.
- No perceptible lag time. Great for live monitoring and PTZ cameras.
- There are no frame rate interruptions, smooth live video and recording. Organic video stream.
- All installers are able to install HD-SDI without any training. Installs like analog. No installation curve.
- Interconnectivity with other brands. Only one flavor of HD-SDI used in CCTV Industry.
- An HD-SDI system can connect to a Network/Internet for remote monitoring/storage.
Resolution Facts
In the CCTV Industry, there are three video formats; analog, IP and HD-SDI, but only Megapixel IP and HD-SDI are considered true HD (High Definition). However, when considering HD solutions you must factor in three vital aspects regarding resolution: recording, transmitting and viewing.
Recording
HD-SDI delivers a digital signal that has not been processed in any way before it reaches the DVR. This raw video stream increases accuracy for video analytics results and renders any view into a clear detail rich image for active monitoring. Simultaneous Audio/Control/Power (POC) transmission over a closed, isolated system architecture prevents packet loss, blackouts and renders the system 100% reliable as long as it is physically connected.
Transmitting
MP IP Cameras compress video packets on the camera itself before sending the data over through the local network for the DVR to record and back through the same network for live/remote monitoring. With HD-SDI, we get a 1080P uncompressed organic stream with zero delay between the camera and the DVR, separate networks for operation and monitoring and a highly reliable system architecture that is immune to package loss and network instability.
Viewing
HD-SDI provides near-zero latency live view that delivers the best real time monitoring experience. MegaPixel IP has a delay of at least 0.5 seconds that could be increased without warning at any moment depending on local network traffic. With HD-SDI the 1080P uncompressed video stream is received by the HD-SDI DVR and then compressed into H.264. Once it’s compressed, it is available as IP video that can be streamed over a network or the internet.
Hybrid Architecture
Our Hybrid Solutions offer the same system architecture, operation and maintenance as CCTV, which provides a smooth transition into the world of HD without any additional installation skills or training and most importantly while providing a lower cost of ownership.
HD-SDI vs Analog
An Analog and HD-SDI installation are very similar since both use coax infrastructure versus using a Network like an IP camera system. This keeps the camera system unaffected by Network outages and glitches. Keeping the security system and the Network separate, creates a more reliable system. Both analog and HD-SDI can utilize a Network/Internet when needed for remote viewing and streaming video to an offsite location.
Hybrid Combination
Since HD-SDI and analog use the same wiring infrastructure, both can be combined for an installation. We have hybrid DVRs which offer both HD-SDI and analog cameras. A customer might only need a few HD cameras and want to keep the rest of their analog cameras in place. In this case, CalSys 12, 16 and 20 channel hybrids would be a great fit. All three DVRs offer four channels of 1080P and the rest of the channels on the unit are D-1 analog.
No Additional Training
If you already install analog, you already know how to install HD-SDI, because an HD-SDI installation looks very much like an analog installation. With HD-SDI, Integrators do not have to become an IT expert to offer their customers HD (megapixel). Upgrade some of the cameras to HD-SDI and keep some of them analog by using hybrid HD/Analog DVRs or replace them all with HD-SDI. The choice is yours.
