Technology & Trends - Digital video recorders (DVRs)
In today’s market, efficient use of bandwidth and storage is an essential part of maintaining an effective video surveillance system. A video management system’s ability to provide analysis, real time event notifications and crucial image detail is only as a good as the speed and bandwidth of a surveillance network. In the physical security industry, H.264 is the video compression format used by most companies. Some companies also employ H.264 enhancements to compress areas of an im...
According to IHS Market, it is estimated that there are over 60 million security cameras in the United States, and other reports say these cameras capture more than four billion hours of footage per week. Over the last decade, IP camera technology has dominated the conversation as it has provided users with a broad offering of enhanced image quality and features. With a large percentage of existing security systems relying on analogue, many end users looking for high definition (HD) video qual...
Dollars spent by video surveillance customers must go towards ensuring high-availability capture, storage and on-demand access to live and archived video. Reaching this goal mandates high-availability of independent components – camera, network, storage (edge, external), internet connectivity, display, all Video Management Software (VMS) components and an architecture that can take advantage of this. In this note, we focus on seeing our way through to a video surveillance architecture, t...
Over the course of the past few months, I have discussed a myriad of topics, from Big Data, the Internet of Things and emerging video surveillance-use cases, to analytics, storage complexities and IT technologies like virtualisation and hyperconverged infrastructure (HCI). All of these trends have a significant effect on the security market, and in April they were highlighted in spades at ISC West. It’s great to talk about these trends but it’s far better to see how they are being l...
Video surveillance as a service (VSaaS) is not just for commercial organisations. Federal, state and local governments can also realise benefits from the technology—and use it to deliver an integrated video surveillance system that addresses some of their unique security needs. Video Surveillance as a Service (VSaaS) What is VSaaS? Simply stated, it’s a cloud-based video surveillance solution that is packaged and delivered as a service over the internet. The price varies depending...
When a news story of global interest begins to break, reporters across the world will scramble to find CCTV footage of the event, however isolated the incident may seem. Given the average of one camera installed for every twenty-nine people on the planet, it is perhaps unsurprising how often a persistent journalist, investigator or member of the public will actually be able to uncover footage. In fact, this number is estimated to be as high as one camera for every eleven people in mature market...
Everybody has been hooked on the discussions about Analogue HD or IP systems, but shouldn’t we really be thinking about WiFi and 5G connectivity, removing the need for expensive cabling? Are wireless networks secure enough? What is the potential range? Even the basic question about whether or not the network is capable of transferring the huge (and growing) amount of data required for High Res Video, which will soon be quadrupled with the advent of 4K and higher resolutions. The future o...
The corporate mantra “Utilise TCO instead of purchase price when making purchasing decisions” means evaluating a project’s Total-Cost-of-Ownership over its lifetime period as the primary cost factor. It requires the corporate buyer to scrutinise the entirety of the investment as opposed to just the upfront purchase price. Like an iceberg, where the majority of the ice is below the surface, the total cost of ownership of a security system is typically much larger than the upfro...
What do users want from their surveillance system? Ask any security professional, and you will hear answers like these: sharp, high quality images; widespread camera coverage; real-time analytics; fast search and retrieval of video footage with minimal, if any, intervention from people in the information technology department. In other words, they want the tools they need to do their job. Delivering those tools requires an underlying technology infrastructure that includes a storage file system...
With 60 percent of all of the world’s data expected to be created and managed by enterprises by 2025 according to IDC, it’s not surprising to learn that enterprise players have moved swiftly to help their customers and organisations maximise the opportunity around this massive data growth. However, when it comes to one of the most significant drivers of this growth in information—surveillance data— many enterprises struggle to understand how they can apply it to do more...
Security solutions should be about integration not isolation. Many organisations are considering their existing processes and systems and looking at how to leverage further value. Security is part of that focus and is a central component in the move towards a more integrated approach, which results in significant benefits. Gert Rohrmann, Technical Manager for the solutions division of Siemens Building Technologies UK, examines how by drawing data from a number of different sources...
Gaps in video from dropped video frames are a common problem. A web search on the phrase “dropped video frames” turns up links oriented towards gamers, YouTube videographers and even the world of video surveillance, discussing why frame drops happen and providing advice for coping with them. On Windows computers, video frame drops are a fact of life. Much of the advice can help reduce the number of frame drops, though never completely eliminate them. If you are an amateur filmmaker...
