Fluidmesh FM3100M-HW MITO

The FM3100 has a tri-band radio operating in the 5GHz ISM band and modulates up to 300Mbps with up to 100Mbps real throughput capability. The MITO system uses Fluidmesh’s proprietary intelligent transmission protocol optimised and prioritised for IP video packet and PTZ data transmission. 

The imbedded FluidMAX technology is used to create Point-to-Point, Mesh & Point-to-Point wireless networks. The highly developed & easy to use FM Quadro system web interface allows user to configure, monitor and troubleshoot the entire wireless network in real time. The unit comes with built-in system tools such as a spectrum analyser, real-time bandwidth monitoring tool, antenna alignment, ping, Softdog and bandwidth tester.

IP Video: The Hidden TCO

WITH benefits such as superior image quality, enhanced video analytics and the integration of surveillance video with business intelligence software, the tipping point at which IP video overtakes analogue is rapidly approaching, and the comparison of their total cost of ownership TCO is becoming irrelevant.
Regardless of which system type ultimately costs more to implement, IP video has some clear cost advantages in its own right. Examples include the ability to run video over a converged cabling infrastructure, using Power over Ethernet (PoE) switches to provide centralized power to cameras, and flexible implementation options (such as wireless video). 
That being said, the switch to transmitting video over the data network can be significantly more complex than with analogue systems.

GE-DS-82 Ethernet Switch from UTC Fire Security

These GE-DS-82 units boast a high-performance wire-speed and switch architecture capable of providing non-blocking switch fabric and throughput as high as 5.6Gbps. Its two built-in Gbe uplink ports also offer incredible extensibility, flexibility and connectivity to the core switch or servers.Plus, with the PoE in-line power following the standard IEEE 802.3af, the GE-DS-82-PoE is able to power on eight PoE devices at distances up to 100 meters through the 4-pair Cat 5/5e UTP wire. These cost-effective managed switches not only deliver easy Web-based management, but also provide a centralized SNMP application to monitor the status of Switch and traffic per port. Affording your current network the opportunity to grow and expand, the GE-DS-82 series provides an advanced WEB and SNMP management interface to meet this demand. With its built-in Web-based management, the GE-DS-82 offers an easy-to-use, platform-independent management and configuration facility.

Virtuous Video Virtualization

THERE are a wide range of environments where any breakdown of the surveillance system can lead to substantial financial losses or significant personal risks: prisons, central banks, and casinos, to name but a few. Here, the ideal situation is obviously to have high availability systems where there is no chance that functionality or picture data will be lost, and where the CCTV system continues to operate completely unaffected even if there are several simultaneous component failures. But is this ideal a realistic proposition, or just pie in the sky?Achieving this level of resilience and reliability presupposes a system designed without any ‘single points of failure’ which could be responsible for influencing the function of the whole system. This requires not only the duplication of critical elements and the intelligent mutual monitoring of all the installation’s components and functions, but also a system of automatic hand-over from failed components to those held in reserve.

HDD versus SSD: Which is Best

GROUND zero in this debate is cost. Storage costs a lot – upwards of 40 per cent of the total cost of system ownership when it comes to video surveillance solutions. And current numbers indicate that SSD costs three times as much as HDD. The upshot of this is that it would be quite possible to install an SSD system that cost as much your HDD-supported entire solution. Yikes.

Of course, SSDs have good points. Because they don’t have the actuator arm to read the platter that’s at the heart of an HDD, they read and write to disk faster. This is a big advantage – especially if you were installing big megapixel cameras and money was no object.

If your surveillance application demands a lot of read and storage and you only have a small storage volume demand there’s no doubt whatever that going SSD will give you a very noticeable performance boost – especially if you are storing at HD resolution (720p) or higher.

Video Surveillance Storage Solutions

OVER the past 10 years or so the financial burden of digital storage on the overall surveillance spend has increased exponentially while at the same time vastly increasing the usefulness of CCTV systems as investigative tools.

In more recent times improvements in compression and analytics and falls in the price of storage are all contributing to a reduction in costs on the one hand while a shift to HD and megapixel cameras makes greater demands on the other.

According to Milestone’s Angelo Salvatore, solutions he is involved with show that while costs are falling users seem to want longer retention times.

“While compression is improving and storage costs are dropping customers are demanding longer retention periods which is directly affecting the cost of storage as part of the overall solution,” Salvatore explains.

Managing disparate networks

MANY organisations in today’s economy see a merger or acquisition as an attractive business strategy to improve financial position and weather a down market. This is especially true in the financial services sector, where even very large organisations are being acquired by equally large organisations as a basic survival strategy. While the results may favour shareholder value and workforce efficiency, the impact of combining the IT infrastructure and IT management processes of two entities can be profound.

Video Trends Unfold at IP Forum

In his keynote, Charles Foley urged the industry to accelerate the push toward IP-based surveillance. Foley, chairman and CEO of TimeSight Systems, urged the industry to embrace IP-based technology rather than relying on the “dead horse wisdom” of analog or strict recurring monthly revenue (RMR) models. Foley identified technological trends such as moving a physical security network to an IP backbone, addressing data storage challenges, thinking about video as data, integrating video into larger systems such as access control or IT networks, and implementing cloud-based storage. Sales growth of IP-based equipment is exceeding 15 percent, according to IMS Research statistics quoted by Foley. He also emphasized the importance of working well with IT managers who are now involved in 60 percent of security purchasing decisions.

Making connections

WHEN electronic security installers get involved in networked security solutions they’re going to find themselves facing a host of connectivity devices, the most common of which are repeaters, especially if the network is employing Cat-5 to get around a relatively large multi-story facility.

Repeaters are essential if a larger network is going to operate effectively. These devices connect different sections of the cable plant, receiving the signal and pumping it back up to full strength to combat attenuation caused by cable impedance. This done, the signal is then sent on its way. Think of repeaters as existing in the physical layer of a network where they support network media comprising the cable plant.

Securing wireless networks

BEFORE we get into this one, it’s worth recapping the sorts of wireless networks integrators and security managers are going to find themselves involved with. The most common RF designations include:

* 802.11: Applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS).

* 802.11a: An extension to 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5GHz band. 802.11a uses an orthogonal frequency division multiplexing encoding scheme called COFDM, rather than FHSS or DSSS.
