Shashi SuperTech : SST
Shashi SuperTech Solutions can become a part of a team where they are not only the supplier, but also a support arm, implementing any new ideas into the project in order to maintain a design based on 21st century technology We are also able to laison with local suppliers assuring the optimum support and service for your needs.
When Shashi SuperTech Solutions is commissioned to undertake a project the client is confident they are assigning the right company for the job. From start to completion SST will be updating you on each phase.
The IP Surveillance Solution
The DVR and IP Surveillance share a number of beneficial features and functions: recording to digital hard disk; no tape maintenance; consistent high image quality; fast, easy image retrieval; access to recorded video over IP networks, etc. However, a more comprehensive comparison of the two technologies reveals how IP Surveillance technology offers a number of significant advantages over a standard DVR: |
- Scalability. IP Surveillance scales from one to thousands of cameras in increments of a single camera. No 16-channel jumps like in the DVR world. Increase frame rates and storage by adding hard drives and PC servers to the network. Any frame rate for any camera at any time is available.
- More cost efficient infrastructure. Most facilities are already wired with twisted pair infrastructure so no additional wiring (which is an expensive part of a CCTV installation) is required. Where there is no infrastructure, installation of twisted pair is cheaper than coaxial wiring. In addition, wireless networking can be used where cabling is unpractical.
- Systems integration and network convergence. IP Surveillance technology provides an open, easily integrated platform. As system integration becomes increasingly critical, IP ensures that access control, heating and ventilation, process control, and other systems and applications can be effectively integrated. A single network connects and manages the enterprise for data, video, voice, etc., making management more effective and cost efficient.
- Remote accessibility. Any video stream, live or recorded, can be accessed and controlled from any location in the world over wired or wireless networks.
- Intelligence. Motion detection, event handling, sensor input, relay output, time and date scheduling, and other built-in capabilities allow the camera to make intelligent decisions on when to send alarms, record video and at which frame rate, improve information access anddecision-making.
- Increased reliability. IP-based data transports enable off-site storage and the ability touse redundant infrastructure, server and storage architecture. By using standard server andnetwork equipment, replacement time if any equipment should go down is considerably lessthan when using proprietary DVR solutions. Management software provides real-time systemm operation status and information on preventive measures.

| IP Surveillance Matures |
| |
| Just as the progressive evolution of CCTV digitisation has yielded improved system performance over time, IP Surveillance promises to continue to deliver a host of attractive, future end-user benefits: |
- Increased intelligence, such as advanced Video Motion Detection (VMD), license plate recognition, event triggers, object tracking, etc.
- A higher resolution than the limits of the analogue NTSC and PAL formats, up to 0.5 Mpixel. Mega-pixel Network Cameras are already available, and soon they will become multi-megapixel.
- Power via Ethernet – eliminating the need to have power outlets at the camera locationsand enabling easier application of uninterrupted power supplies to ensure operation 24 hours a day, 7 days a week.
- Wireless transmission of video using cost-efficient standard technologies such as IEEE802.11b, and wireless access to any video via PDAs, Tablet PCs, and cellular phones.
- Encryption, watermarking and connection authentication at camera level, offering a considerably more secure solution than with any analogue camera.

| Conclusion |
| |
In contrast to common opinion, we have seen that the DVR is just a step in the continuing development of CCTV technology and not an end point solution. Security started with analogue cameras, switchers and tape recorders; today's recording is digital and since the cameras are also turning digital it is natural to go for a: Complete Digital Solution with IP Surveillance.
