Live-streaming mobile surveillance takes cameras to the action

Video surveillance across the world is growing exponentially and its major application is in both public safety and law enforcement. Traditionally, it has been fixed surveillance where cameras provide live streams from fixed cameras situated in what is considered strategic locations. But they are limited in what they can see given by their very definition of being "fixed." The future of video surveillance includes the deployment of more mobile video surveillance with the benefits it offers. Ins...

Why live video streaming is critical for safer and smarter cities

The term “smart city” gets thrown around a lot nowadays, but as different technologies that strive to be defined in this way are adopted by different countries globally, the meaning of this phrase gets lost in translation. The simplest way to define a “smart city” is that it is an urban area that uses different types of data collecting sensors to manage assets and resources efficiently. One of the most obvious types of “data collecting sensor” is the video ca...

Surge protection for security installations: 2017 saw increased investment

In 2017, DITEK saw how power surges from the many natural disasters that took place damaged many businesses. In a natural disaster, or even everyday business operations, a facility’s entire investment in security, life safety and surveillance systems technology can be disabled or rendered useless in a few seconds. Surge protection solutions can mitigate those risks and protect security investments. Proactive approach to risk mitigation Throughout 2017, we also witnessed a change in how...

Are your surveillance monitors prepared for the latest video technology developments?

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...

Saving lives with effective security control centre design

When people think of control rooms, images from James Bond movies or intense action stories come to mind. What they fail to realise is the incredible level of ergonomics, technology, precision and craftsmanship required to create a top-notch command and control room. “These are rooms of complex functionalities, where hundreds of elements must be integrated and function in sync,” says Jim Coleman, National Sales Manager, AFC Industries. Professional teams from several different indus...

Adaptive transmission systems evolve with advanced communications

The security market in 2016 saw an uptick in the economy, the introduction of new technologies, increased compliance requirements in key verticals, and rising concerns over the need for greater security. Users interested in upgrading or deploying new systems consistently chose networked system platforms. This trend further drove the demand for adaptive transmission solutions as a means of repurposing existing analogue infrastructure to accommodate IP devices on a networked platform. As this mi...

Choosing the right cable for networking infrastructure

The use of multiple wires has advantages for network transmission Network connection to a remote device begins by considering the type of cable. In some cases, installed cable may already be present and available for reuse, or you may have the option to install a new cable. Let’s review the major types of cable used for most security applications, their advantages and disadvantages. Types of cables In general, there are four major types of cable. First is coaxial cab...

Nextchip disrupts analogue surveillance market with HD technology amidst growing IP trend

The growing sales of IP-based solutions in the surveillance market is a well-discussed topic. Security companies are rushing to grab a slice of this lucrative pie. However, at the same time, analogue surveillance systems have continued to retain their appeal for many end users. Aware of this demand, some companies have continued to develop technology for analogue solutions despite the IP trend. One company driving this force is Nextchip, the company behind AHD™. Up until rec...

Siklu’s millimetre wave wireless technology supports video surveillance networks with improved capacity

Siklu further expanded its presence in the video surveillance market in 2015. The company released the world’s smallest outdoor Gbps radio to address the issue of densified coverage, which results in the need for high capacity connectivity in surveillance networks – a trend that has snowballed in past years.  Growing video surveillance networks demand greater bandwidth capacity Developments in video analytics and resolutions, requiring high-quality video at the surveillance ne...

2015 sees rise of drone detection systems and the convergence of physical and cyber security

Physical and cyber security convergence, perimeter intrusion detection systems and fibre optic-based sensors were some of the security trends that picked up pace in 2015 and will continue to grow in the coming year as well. The beginning of 2015 started out slowly as the implementation of security projects by a number of organisations was postponed for various reasons. Mid-year picked up momentum, and the year is ending on a strong note. A significant trend was the gradual progression of conve...

Long range identification - 3rd major contactless access control

Recently there has been great interest in long range reading (433 MHz technology) For the last two decades, the primary contactless technology used in access control systems has been the proximity card (125 kHz technology). In the last decade, proximity cards have been augmented by the smart card (13.56 MHz technology). And that's the way it has been until just recently. All of a sudden, there has been great interest in long range reading (433 MHz technology). Merging traditi...

Networking basics for security professionals: Understanding the role of midspans to supply power

Just as with network switches, there are no real standards for midspans In general terms, a midspan is a power over Ethernet (PoE) power source that is placed between a network switch and the device being powered, hence the term midspan. The real question is, with almost all network switches providing PoE power, why do we need a midspan? The answer is, in some cases we don’t, but in others we do. As with any other product we have discussed, we need to first consider that...
