Key-centric access management system: providing the highest possible levels of security

In daily work and life, various locks have always played the role of protecting asset safety. In different usage scenarios, the most appropriate lock must be selected to maximise benefits. In the past applications, the difficulties encountered by managers are as follows. Unlocking authority is difficult to control, unclear access records, emergency unlocking, and troublesome upgrade and installation. Through the following points, how the key-centric access management system solves such problems...

Wire-free, mobile first and data rich? The future of access control is within almost anyone’s reach

The 2020s will be a wireless decade in access control, says Russell Wagstaff from ASSA ABLOY Opening Solutions EMEA. He examines the trends data, and looks beyond mobile keys to brand new security roles for the smartphone. The benefits of wire-free electronic access control are well rehearsed. They are also more relevant than ever. A wireless solution gives facility managers deeper, more flexible control over who should have access, where and when, because installing, operating and integrating...

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...

4 trends affecting physical security power solutions

As the trend from analogue to IP continues to progress, more and more security devices are IP-enabled for seamless network integration With rising concerns over organisations’ physical security and potential network vulnerabilities, it has become more important now than ever for security professionals and other decision makers to take actions that will guard against potential problems and help prevent system failures. One specific area of heightened focus is the implemen...

Extenders convert media for longer video distance runs

IP/PoE systems eliminate the need for local power, thus saving installation costs Cost considerations are an important reason to use existing installed cable as part of a new system infrastructure. Extenders in the form of media converters can help. For almost three decades, video surveillance systems existed in the form of analogue systems. Video coaxial cable was the primary method of transmission with a limited distance of about 750 feet. Analogue systems required separate...

Beyond PoE standards – factors that can cause component failure

When a manufacturer states a specific PoE power for a camera, always count on the maximum class power source Power over Ethernet (PoE) is an important consideration in IP video security infrastructures, and many people believe Institute of Electrical and Electronics Engineers (IEEE) standards are the last word. However, when it comes to PoE, there is a wide range of both voltages and wattages that can qualify as being within an individual IEEE power class. This applies to both...

Considerations when designing an IP video security infrastructure

Too often we attribute failure of connected devices to the devices themselves when the problem is actually an infrastructure failure Network infrastructures for security devices are complex. It may seem simple to connect an Ethernet cable to a cable modem, but the connection of IP cameras, access control devices and other IP/Power Over Ethernet (PoE) devices is not nearly so simple. Infrastructure is the heart of any system; and too often we attribute failure of connected devi...

Do’s and Don’ts of managing legacy systems – Migration better than rip-and-replace for enhancing security control system functionality

Systems may be reliable and performing as originally intended, but can also beoutdated in comparison to current technology offerings Let’s start by defining what a legacy system is in the context of a security control system. Legacy refers to an installed and operating security control system made up of numerous components, both hardware and software, that have been eclipsed by newer technologies. A shortage of parts and pieces may be creeping in, and it’s also li...

Remote power management of networked systems offers uninterrupted security services & new business opportunities

By adding remote monitoring to service contracts, dealers and end users bothbenefit from substantial cost savings while reducing potential downtime Whether upgrading an existing surveillance and/or access system from analogue to IP, or installing a completely new system using structured cable, the ability to communicate, monitor and control IP devices delivers significant operational and economic benefits. The vast amounts of data these systems generate are useful in many ways...

Ethernet switches – Powering IP surveillance systems the smarter and more economical way

Ethernet switches are often overlooked andsometimes deemed a cheap connectivity pointwith little to no importance The Ethernet switch is a critical link between cameras, network video recorders (NVRs) and computers that need access to video feeds. The Ethernet switch not only provides the data connectivity but often the power to the IP cameras via Power over Ethernet (PoE). Ethernet switches are the fundamental backbone of a Local Area Network (LAN) and the critical connectivi...

Power supplies: critical component of security solution effectiveness

Security integrators prefer to standardizetheir choices of system components such as power supplies using security manufacturers they are familiar with Power supplies may be inconspicuous and literally out-of-sight; however, they play a critical role in the effective functioning of security solutions.  Selecting and using the right power supply is an important aspect of ensuring that the installed security system delivers the desired outcome and of course, a good ROI. In...

Power supply requirements and options for access control systems

The power supply is the key driving force for access control systems Power plays a crucial role in the effective functioning of any access control system and the choice of the right power system to suit specific requirements is important. In this article, Ronnie Pennington, National Accounts Manager of Altronix Corporation explains various ways to determine and meet the power requirements for access control systems. Usually, an access control system itself acts as the main so...

Choosing the right power supplies for security installations

 Selecting the optimum power supply for a system is critical to an installation  When it comes to selecting power supplies, knowledge is power. Determining the power requirements of every systems product, taking into account their integration with one another is critical to ensure that you are selecting and installing the power solutions most appropriate for your installation. Such information will enable you to select the power supplies that will be required to keep your security sys...
