SICK’s Visionary Camera Takes 3D Images in a Snapshot

SICK has launched the Visionary-T,  its first robust, industrial imaging camera to capture high-resolution 3D data with a single ‘snapshot’, whether the object is stationary or moving.

The SICK Visionary-T uses high-resolution Time-of–Flight (TOF) technology to achieve superior quality 3D imaging for vision applications.  Unlike 3D vision systems based on laser triangulation, the 3D image is captured with one shot of light, without the need to profile a moving object.

While single shot imaging systems have already been introduced for consumer applications, the IP67-rated SICK Visionary-T is designed for 24/7 industrial use in rugged conditions.  The camera therefore offers an affordable alternative to high-end 3D vision systems so that manufacturers and machine builders can integrate 3D imaging into intrusion detection systems for building security applications, for example in museums and art galleries.

Explains Neil Sandhu, SICK’s National Product Manager for Imaging, Measurement, Ranging and Systems:

“The Visionary T builds up a detailed and accurate real-time 3D image of fixed or moving objects with excellent results regardless of angle, surface finish, material or shape of object. The Snapshot technology means it is not necessary to design a system in which either the camera or the object must move across a laser line to create a triangulated image.

“In a single shot, the Visionary T combines different aspects of the light scattered by the object to build up a detailed picture of shape, distance, reflectivity and object depth.  Our trials have shown that the single shot method performs well, with less false imaging than can occur with some of the other commonly used methods, and lead to far more reliable results over a wide range of conditions.”

The SICK Visionary-T uses Time-of-Flight measurement of a light signal between the device and the target for each point of the image. The CCD/CMOS imager develops a pixel matrix, with each pixel containing depth and intensity information.  The camera is designed to capture more than 25,000 distance and intensity values to create real time 3D images at up to 30 frames per second.

Available in two different models, the SICK Visionary-T CX delivers raw data as depth, intensity and confidence values without any post-processing or reduction for in-house processing and program formulation, while the Visionary-T AG outputs filtered data in formats pre-selected by the integrator, OEM or other user. Likely to be used primarily for robot related tasks, typical data handling includes axis manipulation, parameter configuration, polar, scalable height integration time and different filter types.

Easy to mount, either on a vehicle or frame at the optimum angle for operation, the SICK Visionary-T is fitted with an industrial standard API connector for easy communication of the 3D data for evaluation on an external computer. Data can be read or recorded either directly via SICK’s SOPAS interface or via API for matlab, java or C++, and the SICK Visionary-T is compatible with SICK’s IDpro platform for integration with other SICK vision and sensor devices.

Installer selects INTRATONE systems for entire client portfolio

A specialist security installer, Green Gate Access Systems, is rolling out Radio Frequency (RF) receiver equipment manufactured by INTRATONE, one of Europe’s largest access control businesses, across its entire portfolio of 400 clients with secured doors and gates.

As well as this, Green Gate Access Systems is also installing Intratone’s audio and video intercom equipment at many sites, and in particular its INTRABOX access control range.

The technology comes with a monthly subscription contract (without binding duration) or with a 15-year pre-paid GSM SIM card. All of this and is managed remotely by INTRATONE’s management platform.

Neil Sampson, Managing Director at Green Gate Access Systems, says that these features offer significant benefits: “With previous GSM-operated access control systems, the SIM card often proved to cause major problems,” he says. “However with a pre-paid system, the question of where the card comes from and any issues over payment are removed, and what was a major barrier is no longer a consideration.

“Likewise, we are able to operate, monitor and update every access control system from one platform, which saves time and money and removes the logistical challenge of visiting each site on a regular basis to carry out simple works,” he continues.

The systems are operated by proximity reading key fobs, which are also remotely managed. If a user loses their fob, the operator is able to immediately establish its identity and disable it for future use. A new fob is subsequently activated and then despatched. Every time a fob is used the data is sent back to the remote operating platform, giving operators an overview of that particular gate or secured door’s activity. Any unusual activity is therefore easily identified and monitored.

Green Gate Access Systems was introduced to INTRATONE by Cardin, which is one of its key distributors, as its Sales Director, Jason Gregg explains: “We have built an excellent relationship with the manufacturer which understands the needs of end-users and removes much of the complexities,” he says.

“INTRATONE’s back-end operating system is easy to use, and therefore its equipment is quickly becoming a product of choice for many end users.”

Nicolas Gaine, International Sales Manager at INTRATONE, says this is a good example of the partnership network that it has built with distributors: “Excellent relationships are a must in our industry and we have successfully maintained them to a level that our volume of work is increasing steadily via this route,” he says.

“With pre-paid GSM systems, product reliability and our operating platform we are reaching out to a broad range of suppliers with end users in a multitude of industries,” he concludes. http://www.intratone.com

Security, access control and smart locks – what’s safe, what’s the difference and where do we draw the line?

Here, Justin Freeman, technical manager of The Master Locksmiths Association (MLA) – the leading trade association for the locksmithing industry – talks about the difference between security and access control, considering the problem of smart locks and the role they play for both.

Facilities managers have long understood the value and convenience of a good access control system by being able to control the access to certain parts of a building to certain individuals. Access control can start with a very simplistic form of digital code lock (mechanically operated push button locksets) operated by a simple code right the way through to complex internet controlled systems that enable managers to add or delete users from a central location.

Access control can directly link to fire safety and when the Regulatory Reform (Fire Safety) Order 2005 (RRO) came into force in 2006, it had a significant impact on facilities managers. The RRO dispensed with the need for a fire officer to certify and audit buildings, with responsibility for complying with the Fire Safety Order resting with ‘the responsible person’. Therefore, if, as a facilities manager, you are named as the person ‘who has control of the premises’, you must ensure compliance with the Fire Safety Order and operate good practice in all aspects of safety and security. A risk assessment must be carried out to make sure access control has the correct fail safe/fail secure operations in place. A professional like an approved MLA member could help to make sure everything is in order.

Facilities managers need to have a good understanding of health and safety requirements including things like escape routes and fire doors that access control will be integral to, so things are easy to get wrong and could well get a little more complicated.

The crossover between security and access control

Access control manufacturers, suppliers and facilities managers have long understood that these products are not primary security products and are there to restrict access (usually used internally within a building, with doors leading to the external of a building being secured by tested security mechanical locks). Access control therefore is not tested to any security or attack standards. People using a facility without the level of knowledge of facility management will assume any door with a lock on it is secure but this is not a problem when used and specified correctly.

The MLA recently exhibited at the Smart Buildings section of UK construction show at the NEC Birmingham and we spoke to lots of facilities managers regarding security, safety and convenience. All of them found the convenience of access control to be vital to the smooth running of their buildings and many were very interested in a smart lock that we had on display.


The benefits and pitfalls of a smart lock

‘We are seeing new technology introduced at a high rate within the UK in the form of smart locks that can be operated by code, tag, swipe card, biometrics and most importantly by smart phone. Facilities managers could see a direct benefit of having security locks on their buildings with the features and benefits of access control and even locks that can talk to things like CCTV, alarms and would ideally like security locks that could even be directly linked to access control and managed in the same way. The high interest in devices that operate heating and lighting via smartphones makes it obvious that people would like to operate their security locks if not remotely, then with their smartphone.

However, the UK has for a long time had excellent security standards for mechanical security including BS 3621, 8621, 10621, BS EN 1303, BS EN 12209 and PAS 24 for complete windows and doors. We can easily test the mechanical strength and capability of the actual lock but at the moment we cannot easily test the security of the ‘electronic key’ (i.e. fob, card, phone etc.) on electronic smart locks. It’s the ‘key’ that has actually become the problem area here as it could be anything from your finger, eye, face, voice, card, tag or phone (and I am sure there will be more) and the device could potentially store security information on a database online.

Industry is working on developing standards that smart locks could be tested to but this technology moves quickly so the truth is – we don’t know how secure these products are at the moment. The unfortunate advice the MLA has to currently give therefore is if you want to use a smart lock on your security door for convenience that’s fine but it must be supported by a tested mechanical security lock to secure the door properly. So smart locks are currently considered as access control and therefore secondary security rather than primary security.’
