Sera4 Protects at Exploreservice

In Argentina’s province of San Juan, Exploreservice’s main offices and workshops store critical materials such as explosives. Exploreservice is a rock driller; excavating for the mining sector and for civil construction works, such as the layout of new roads.

The Need

Exploreservice needed strict access control to tools and magazines for handling explosives. They needed traceability of the materials, and records of the people who accessed them. They needed a robust solution that could work outside without issues. The most demanding requirement came from the remoteness of their storage facilities: They are often difficult to access, and often without connectivity or communications.

“Before adopting Sera4 padlocks, we used conventional locks. Workers would routinely forget and lose keys, causing us to break and change locks often. The protection we had then was more rudimentary and basic. Since learning about keyless locks, we have been looking for them until we finally got several units to start up in our plant. We now have more fluid and secure control of our facilities, since Teleporte tracks the entry and exit of people”, comments Alejandro Acosta, partner Manager of ADL S.R.L/ Exploreservice.

And he adds: “In addition to the security of such a robust and efficient padlock, what interested us in the Sera4 solution provided by ABEI was the management of information and control of all the movements of a secured area with keyless padlocks and controllers. This optimizes performance and streamlines our operations”.

The Challenge

“Most of the time we do not have connectivity and communication, and the terrain can be difficult. When workers arrive, it’s a massive inconvenience if they have a problem with the lock. The costs incurred by the simple act of replacing a lock or a key in such a remote and difficult to access site is surprisingly high”.

The Solution

“After significant discussion, we decided to adopt Sera4. Now, with this solution implemented, the problem is solved. We have the safest job, and we even have ways to get the job done with little or no connectivity, thanks to the manual option of padlocks and locks. We can really say that Sera4 is solving multiple problems for us that may sound simple in a city, but that turn out to be a great complication when we are far away in the countryside”, explains the executive.

In the past, Exploreservice suffered some internal losses due to a lack of effective control, and some lack of records in handling the flow of spare parts and tools. Alejandro Acosta highlights that now, by having traceability and a strict record of the person who enters and at what time, that diversion gap is significantly reduced. According to Acosta, “the great advantage of the product is that it has great flexibility and offers a range of possibilities…so we hope to discover new tools that will be useful in various areas of our company’s development.”

The Implementation

The executive explains that crafting the deployment plan was the longest part. The installation of the product itself was easy. “For this, the support and advice that ABEI gave us was of vital importance. Both in listening to needs and in advising for optimal coverage, as well as in projecting needs to be implemented by the Company”.

He highlights the contribution of ABEI, whose permanent support proved to be essential. ABEI delivers with immediate help and assistance, in addition to addressing any concerns. ABEI has proven to be “a strategic partner in the area of ​​security”.

Dronedek to offer secure keyless access control with Sera4

WATERLOO, ON – August 29, 2022 – Dronedek, known for its automated “mailbox of the future”, a device that secures and temperature-protects traditionally or autonomously delivered food, mail and packages from any delivery service, today announced their partnership with keyless access control provider Sera4.

“We’re locking arms with technology leaders like Sera4 to help build a robust ecosystem for our users,” said Dronedek Chairman and CEO, Dan O’Toole. “Through this partnership, Dronedek will have a secure way to grant temporary access to delivery and pickups services by issuing digital keys.”

O’Toole said there are several benefits to keyless access control including speed, convenience, and flexibility. “Additionally, in keyless systems, users don’t need to carry badges, keys, or fobs. This is especially important in an increasingly contactless and post-pandemic world.”

In the future, Sera4 may provide Dronedek with additional features beyond keyless access control. The company also offers market-leading software and hardware, connecting a network of controlled access through smart digital and physical locks.

“We are excited to be a member of Dronedek’s distinguished partner portfolio,” said Sera4 VP of Global Sales, Eric Corej. “The Sera4 Teleporte platform is a scalable and end-to-end encrypted keyless access control solution which provides secure and reliable access to the Dronedek through the use of a mobile device such as a smart phone or tablet.”

Dronedek plans to integrate Sera4 mobile access control in select phases of upcoming pilot programs. Recently, the company completed the first phase of its inaugural pilot in Lawrence, Indiana, where, for the first time in the world that First-Class mail was delivered to Dronedek smart mailboxes by USPS mail carriers, as well as one of Indiana’s first drone deliveries of a McDonald’s Big Mac and french fries.

Solarpack chooses Sera4 for Solar Farms in Chile

Originally published in Spanish by RevistaInnovacion, on 4 July 2022.

Without the need for a data network, power supply or installation, Sera4’s keyless access control solution for critical and remote sites is 100% offline. This implementation case teaches how a Spanish company manages access for qualified personnel to its electrical installations throughout Chile.

Solarpack needs access control

Solarpack is a Spanish-owned company specializing in the development, construction and operation of large-scale photovoltaic solar projects, with a presence in fast-growing markets in Europe, North America, Latin America, Asia and Africa.

They have commissioned 211.6 MW at ten sites in Chile. In 2021, changes in Chilean law regulated the operation and maintenance of low, medium and high voltage facilities. Many companies are implementing systems to comply with the requirements of regulation NFPA70-E.

Solarpack selects Sera4

Solarpack chose Sera4 keyless access control because:

  • AP3 padlocks do not require any type of installation, power supply or data network.
  • The solution works 100% offline, which is very important for remote parks with low connectivity.
  • The possibility of issuing digital keys from Solarpack headquarters in Santiago de Chile, to users located in any solar park.

Now, only qualified personnel enter its electrical installations and it is in compliance with regulations.

Results of the deployment

The first phase of deployment covered solar parks located in Calama, Granja and Pozo Almonte. All these sites are located in the Atacama desert, the driest in the world, an ideal place for the installation of solar parks but a huge challenge for any type of equipment to be installed.

After a quick implementation, Solarpack received the training and started using Teleporte. In the first two weeks of operation, we could automatically track 382 visits to the equipped facilities. This audit also allowed to control that the sites have been closed correctly and the duration of each visit.

Once the implementation of the solution in Calama, Granja and Pozo Almonte is completed, Solarpack will continue with the remaining solar parks in Chile.

Cerento Selects Teleporte Keyless Access Control to Centralize Access Management

WATERLOO, ONTARIO, June 1, 2022 – Cerento Inc., an EPC (Engineering, Procurement and Construction) Company headquartered in Riverton, WY, has selected Sera4’s Teleporte keyless platform to provide centralized management for site access and security.

Cerento designs, installs and maintains a variety of customer fixed wireless, microwave and fiber optic networks across the US. Part of Cerento’s core offering is a network management service, which monitors and maintains client networks ensuring reliable service around the clock.

Site and service maintenance often requires immediate physical access. Before adopting Teleporte, Cerento customers struggled with site access and security.   Access codes were lost, locks were being cut and delays were caused by access issues to critical network infrastructure.

Teleporte keyless access has resolved those persistent issues. Sera4 armored keyless padlocks were installed at all critical access points. These are easily reassigned from one point to another as requirements demand. Without having to coordinate physical keys to enter sites, Cerento freed up more time to work on other projects and issues.

“The Sera4 Teleporte access control solution has streamlined our site security and access.  We have been able to easily and cost effectively adapt our existing locks with the Sera4 locks and onboarding the new systems into Teleporte is easy and quick!” says Kim Kobbe, President of Cerento. “We were up and running with it in no time.”

With the access problems addressed, Kobbe described how Cerento found added value in not having to rekey locks anymore. Cerento has also been able to optimize their operations further based on profiled access data collected over time.

Sera4 protects critical infrastructure in remote places around the globe. Teleporte, Sera4’s keyless platform for physical access control, is both easy to use and highly secure. Operating across four continents, Sera4 provides security and identity control for some of the world’s largest service providers.

“It is a privilege to work with and support Cerento’s organization with Teleporte keyless access,” says Eric Corej, VP of Global Sales at Sera4. “We are designed for telecom infrastructure service for harsh locations and for harsh climates, which meets the requirements for Cerento’s applications. It means a lot to us to create real value as we solve problems in the broadband space.”

Clearwater County Selects Teleporte Keyless Access Control to Secure Broadband Assets

WATERLOO, ONTARIO, CANADA, March 22, 2022 / — Clearwater County, a rural community in Alberta, Canada, has selected Sera4’s Teleporte keyless platform to provide secure, scalable, and simple access control for its Broadband Internet assets.

Clearwater County’s Broadband Internet Project aims to deliver high-speed Internet connectivity to the residents and businesses in the county. Most of the County is under-served by available internet services, especially those that meet the standards of the Canadian Radio-television and Telecommunications Commission’s (CRTC) standards for broadband speeds. This multi-year initiative requires the establishment of a high-capacity broadband backbone structure throughout the County, which has required new critical infrastructure and cooperation between the County and internet service providers (ISPs) and wireless internet service providers (WISPs).

Clearwater County covers an area of almost 18,700 km2 and the infrastructure supporting the Broadband Internet Project is spread across the County. With some sites located hundreds of kilometres from the County’s central administration offices, issuing physical keys to employees, contractors, and service providers was logistically challenging. While the sites themselves are open access, the County shares secure facilities with the ISPs and WISPs, and different keys need to be issued to different technicians and contractors to service the infrastructure. Tim Quinn, Broadband Technologist at Clearwater County, wanted to eliminate key and pass card management altogether, and sought a solution that would allow his team to grant and revoke access to various users, as needed, without having to travel to remote sites.

“Teleporte provides a unified platform that makes it easier to manage access throughout the broadband network, and saves us the time, effort, and cost related to lost keys, changing locks, or replacing access cards,” says Quinn.

Clearwater County trialed Teleporte-enabled lock controllers on a shelter in Ferrier, Alberta. Quinn was impressed that the solution stood up to the harsh conditions of a Canadian winter, and they built two new shelters with lock controllers pre-installed. The plans for expansion of the Teleporte solution include swing handles with lock controllers on the client side, allowing ISPs to access their cabinet bays, and Teleporte-enabled padlocks on the site gates. This deployment approach will assure a fully keyless workflow at the site, which delivers operational efficiency, and will provide detailed access logs, which contributes to site security.

“Teleporte is easy to configure and allows us to provide short- or long-term access to different sites, locks, and doors, all through the same platform,” says Quinn. “We can issue and revoke keys from anywhere. If someone leaves the County, or an ISP, or a supplier has a technician leave the company, it’s easy to remove them from the platform. That’s worth its weight in gold”.

Clearwater County has also found that using Teleporte adds an additional layer of safety for contractors and technicians. “When we send out a work order, we know when the technician arrives and leaves,” says Quinn. “This is important when we’re sending people to remote sites; if someone doesn’t show up or lock up as expected, it gives us a heads up that we should check on them.”

Sera4 protects critical infrastructure in remote places around the globe. Teleporte, Sera4’s keyless platform for physical access control, is both easy to use and highly secure. Operating across four continents, Sera4 provides security and identity control for some of the world’s largest service providers.

“We are thrilled to work with Clearwater County, and it’s a privilege to serve and support projects that help enable the delivery of Broadband Internet,” says Eric Corej, VP of Global Sales at Sera4. “We look forward to working with Tim as he expands the use of Teleporte throughout the County, and we’re proud to provide a solution he can count on to keep the residents and businesses of Clearwater County connected.”

Schneider Electric Power Field Service Selects Teleporte Keyless Access Control to Secure Critical Assets

WATERLOO, ONTARIO, CANADA, January 13, 2022 — Schneider Electric Power Field Service, based in Canada, has selected Sera4’s keyless access control solution, Teleporte, to secure its critical field assets.

Schneider Electric provides digital energy and automation solutions for homes, buildings, data centers, infrastructure, and industry. The Power Field Service at Schneider Electric is responsible for the modernization and maintenance of existing electrical infrastructure and new installations, along with automations and energy management.

Schneider Electric selected Teleporte to address a unique challenge. The Power Field Service uses a state-of-the-art 3D scanner to collect inputs into engineering designs. The scanner is shipped to different regions around Canada, and the Operations team was struggling to find a solution to secure the Pelican case that holds the 3D scanner, without requiring a physical key to be mailed in a separate shipment.

A Teleporte-enabled padlock solved this problem for the Power Field Service Operations team. Administrators can issue digital keys via Teleporte, allowing the recipient of the 3D scanner to open the padlock via Bluetooth. In addition to the ease of access to the scanner case, the padlock and Teleporte provide more administrative control to the Operations team, giving them insights into where the asset is and who’s in possession of it, at any time.

Ivan Filipic, Director, Ecofit Canada at Schneider Electric Field Service, led the selection process for Teleporte. “Sera4’s access control solution is an example of how our society is going through a digital transformation,” says Filipic. “This solution solves our access control issues, and allows us to secure high-value and sensitive equipment or installations.”

Sera4 protects critical infrastructure and assets around the world. Teleporte, Sera4’s keyless platform for physical access control, is easy to use, highly secure, and offers best-in-class reliability. Operating across four continents, Sera4 provides security and identity control for some of the world’s largest essential service providers.

FortisBC Selects Sera4 Keyless Padlocks to Secure Electronic Vehicle Charging Stations

WATERLOO, ONTARIO, July 21, 2021 — FortisBC, a British Columbia-based utilities provider and a subsidiary of Canada’s largest privately-owned utility company, has selected Sera4 to provide secure, reliable, and scalable access control to its electronic vehicle (EV) charging stations.  

Fortis BC Logo

FortisBC owns and operates over a dozen Direct Charge Fast Charging (DCFC) stations throughout British Columbia, and needed a secure, modern solution for granting access to these stations without requiring traditional keys.  

Michael Leyland, Manager of Innovation Initiatives at FortisBC, led the implementation of Sera4. Prior to launch, Leyland had no visibility into who was accessing the DCFC stations, when they were accessing them, or how long they were there. Measuring contractor response time and reconciling invoices for work completed were challenging, because Leyland didn’t have access to automatic audit trails on FortisBC’s assets. 

“Sera4 is a game-changer,” says Leyland. “Being able to issue an electronic key for a contractor 200 kilometers away to service a charging station is a much better experience for us, our contractors, and ultimately our customers. That’s what Sera4 has done for us—we can get the critical infrastructure that our customers rely on back up and running faster, because we don’t have to worry about how we’re going to get a traditional key to the contractor that needs it.” 

Sera4 protects critical infrastructure in remote places around the globe. Sera4’s keyless platform for physical access control is both easy to use and highly secure. Operating across four continents, Sera4 provides security and identity control for some of the world’s largest service providers.  

“We’re thrilled to partner with FortisBC to provide a secure, reliable solution that helps them serve their customers better,” says Eric Corej, VP of Global Sales at Sera4. “We love that FortisBC is leveraging the insights and audit trails delivered by Teleporte [Sera4’s software platform]. That’s what we’re really selling—identity intelligence.”
