Are Cheap CCTV Lenses Ever Acceptable?

This Fujinon lens offers the elevated performance levels security managers should be looking for.
This Fujinon lens offers the elevated performance levels security managers should be looking for.

SEN Help Desk has made some interesting points about lensing lately but wouldn’t you agree that even with relatively low cost lenses attached to compact cameras there’s a sweet spot in the centre which offers universally high performance? Given this, is lens selection as important as you suggest?

Answer: We’d reiterate that low cost lenses with good, simple designs without too much internal tolerance (in the case of varifocal) and with suitable coatings against internal reflections can offer unexpectedly high performance. So we may well agree with you. But if you mean that poor performing lenses with excessive barrel distortion, vignetting, chromatic aberration and flaring from lens elements and/or housing windows or dome bubbles, can be excused their deficiencies thanks to a portion of admissible image that comprises say, 50 per cent of the camera view, we think not.

Special Report: AIC Study of Council CCTV Systems

SafeCity Control Room, Ipswich City Council
SafeCity Control Room, Ipswich City Council

One of the fastest growing CCTV user groups in Australia is local councils. Research conducted by the Australian Institute of Criminology gives a snapshot of market penetration, an idea of system size and topology, as well as a sense of the usage and value of these public surveillance solutions to police investigations.  

RESEARCH conducted by the Australian Institute of Criminology into public surveillance systems installed by councils around Australia is highly instructive given the fact it’s hard to get a sense of the number of systems, how they are used and whether or not they provide value. The AIC’s research on the subject was published last year and while there’s been continual growth in the market since, the findings remain valuable for industry and end users.

BGWT’s Rob Meachem is one of electronic security distribution’s most experienced leaders. Now tasked with taking BGW Technologies to next level, he discusses the company and the opportunities and challenges facing the distribution market. In the Interview this month, Rob talks with SEN editor, John Adams.

JA: How does it feel to be back in the electronics security industry, Rob? Are you enjoying yourself?

RM: It feels great but to be honest, having so many strong relationships and friendships in the industry, I hardly felt I ever left. Certainly, a lot has changed in 2 years and I’m loving being a part of helping to grow this young business. 

JA: Tell us about BGWT, it’s a bigger company than many people in the local security industry realise, isn’t it?

Electronic Security Mergers & Acquisitions: What Do They Mean?

M&A, here to stay?
M&A, here to stay?

THERE have been so many mergers and acquisitions in the electronic security market over the past 12 months it’s enough to make your head spin.

Honeywell has bought Xtralis, is looking to divest its Building Controls business and has talked merger with UTC. Ingram Micro is being bought by HNA, Apollo has bought ADT, Johnson Controls and Tyco are merging, FLIR has acquired DVTEL, Hanwha has bought Samsung Techwin and Canon has acquired Axis and Milestone. What do these acquisitions mean for installers, integrators and end users? Do changes of ownership undermine the nature of an organisation, disrupt its lines of product development? And what is the motivation for the current flood of M&A activity?

Home Automation Trending

Home automation and security growing together
Home automation and security growing together

Home automation is continuing to trend, with overseas takeup suggesting it’s likely local monitoring providers who are doubling down on home automation capability are on the track.

ELECTRONIC security systems, home and office automation solutions and broadband internet and cloud continue to enhance and complement one another – so much so it seems that automation solutions are beginning to look as if they may attain ubiquity. Is it likely the homes and SMEs of the future will expect automation capability that combines intrusion detection, access control and video surveillance as a matter of course – that all well-designed secure and energy efficient homes will include considerable levels of automation?

Security Electronics & Plate Tectonics

Security Electronics and plate tectonics
Security Electronics and plate tectonics

TECHNOLOGICAL development in every area of security electronics has become tectonic – the underlying layers are all in motion. 

It’s a paradigm that demands more from everyone – more development, more education, more technical training, more standards, more open-mindedness. And behind this new paradigm we’re seeing more investment in infrastructure, facilitating expansion of the capabilities of solutions - demanding a living and breathing comprehension of multiple layers of networking. Everywhere in the market there’s change. You see it in management software, in control panels, in devices – whether cameras or intrusion alarm sensors, or access control readers and expanders. And much of this change swirls around the governing imperatives of networkability and integration.

Most Influential Security Products & Technologies of 2015

Inner Range SkyGuard
Inner Range SkyGuard

What were the most influential products and technologies of 2015? It’s always difficult to find a balance between the solutions that catch the market’s momentary attention and those solutions that will go on to have a serious impact on the way we conduct our business.

KEY products and technologies in 2015 included mobile app management of security and automation solutions, improvements in CCTV camera technology – particularly increased resolution, reduced bitrates and larger sensor sizes - and the ongoing process of developing management solutions that allow single-workstation management of multiple subsystems, locally and globally. Other trends include falling costs, the elevation of risk for law enforcement agencies and other government departments, as well as in public spaces.

The Shape of the Future of Security Electronics

Merry Saturnalia, electronic security people.
Merry Saturnalia, electronic security people.

 ELECTRONIC security has always been about finding a balance between dichotomous needs; hair trigger sensitivity, yet reliability; easy access, yet high security; low light performance yet wide dynamic range; high resolution, yet low bit rate; low price yet high quality; ease of installation, yet powerful integration. 

Looking back over 2015, it’s possible to see the tension imposed by all these improbable bedfellows, to see the ways in which the laws of physics and the forces of the market end up shaping our solutions, rough hew them how we will. Alongside these conflicting demands, however, it’s also possible to see the shape of a future beginning to emerge. It’s a powerful future.

DIY CCTV Fails to Find Price/Performance Crossover

DIY satisfaction not taking off

IF there is a perfect price performance crossover – the spot on an axis in which price and performance intersect in just the right way – it seems DIY camera makers have failed to find it when it comes to home automation systems.

As installers know, there’s a point at which spending less on hardware buys you more trouble, not more margin. But consumers have a lot to learn, if a recent study by Argus Insights is anything to go by. 

“According to overall consumer feedback, there is immense room for improvement,” Argus wrote in its report. “Distrust from consumers about the reliability of connected devices is obstructing growth in consumer adoption (of home automation).”
