Water utility simplifies operations with Cliq

London, UK

“All the energy is in the key,” says Christophe Nublat, Head of Study and Works Division at Eau de Valence. “There is no power supply to the lock, and therefore very little maintenance.”

French water utility Eau de Valence needed to upgrade an ageing mechanical locking system. They demanded access control that could manage multiple and dispersed utility sites; perform reliably outdoors in any weather; and log and monitor all system users from a single control point. Cliq key-based access control technology from Assa Abloy was the chosen solution.

Eau de Valence selected Protec2 Cliq mechatronic locks with mechanical disc cylinders and encrypted electronics. Assa Abloy partner AC Pro installed around 40 programmable Protec2 Cliq cylinders and padlocks across Eau de Valence sites, and issued 20 battery-powered keys, one for every authorised user.

Now, a comprehensive audit trail for every lock and padlock is available on demand, so monitoring the frequency of contractor and other key-holder visits is easy. It is straightforward to tailor anyone’s access rights by restricting key validation to specific times or dates, if needed. Removing access permission from lost or stolen keys is easy with the Cliq admin software. Weekly mandatory key revalidation provides yet another layer of security.

Five Eau de Valence keys are also equipped with Cliq Connect technology, to allow supervisors to update their key access permissions on the move, via Bluetooth and the Cliq Connect app, in the event of a problem arising when they were away from base or on-call.

With Cliq, power to each cylinder is supplied by a standard battery inside every Cliq key, so installation was fast and cost-effective. There’s no wiring at all — making it an ideal retrofit solution for doors and padlocks at sites where connecting mains electricity is difficult or impossible.

“All the energy is in the key,” says Christophe Nublat, Head of Study and Works Division at Eau de Valence. “There is no power supply to the lock, and therefore very little maintenance.”

In addition, Cliq padlocks can handle weather extremes and secure almost any opening, making the Cliq solution much more adaptable than standard electronic access control systems. It is also easy for Eau de Valence to manage mechanical and electronic locks in the same installation: “The electronic and mechanical cylinders are managed by one and the same key,” adds Christophe Nublat.

Despite all this extra convenience, there have been no compromises on site security. Communications between lock and key are encrypted. Because there are up to 1.97 billion unique key combinations, there’s unlimited scope for any utility to design its own mechatronic key-based access system to suit its own specific needs — however challenging.  Cliq technology is already protecting critical infrastructure sites all over Europe.

Etherwan simplifies complicated migration to digital traffic surveillance

The advantages of traffic surveillance cameras have become broadly acknowledged over the past several decades, and seeing multiple video cameras at a single intersection is now common in major cities throughout the world. However, video surveillance technology has evolved rapidly, and in recent years the adoption of IP over analogue systems has become a major trend. This has created many new and unusual challenges in network design and implementation.
