Update 9/10/20: COVID-19 Supply Chain Considerations – Southwest Microwave

When COVID-19 hit the international supply chain was severely disrupted. Some material movement ground to a halt as product demand stalled and factories closed, while there was immense pressure to move essential commodities (Fast Moving Consumer Goods – FMCG) and healthcare products. We learned from some clients that as warehouses strained to reorganize inventory, material was left on trailers or on docks in containers where they were more vulnerable to theft. This article in Corporate Compliance Insights highlights some previously unseen supply chain issues.

Southwest sensors have been deployed to protect supply chain assets for decades. Clients include auto, truck, RV and golf cart manufacturers, tire manufacturers, pharma logistics facilities, durable goods facilities, and clothing distribution.

The key to a successful deployment for distribution operations is understanding what is at risk and when/where are goods most vulnerable. There is no substitute for starting with a physical security risk assessment (RA) followed by a vulnerability assessment (see January 15, 2020 post “Is There More to Perimeter Security . . .).

While most Southwest deployments are fixed, we provide excellent portable rapid deployment sensors for products that are moved about from week to week or month to month.

Does it make sense to have a conversation about protecting your company’s supply chain?

Updated 9/11/20 Denning Electronics and COVID-19

Our manufacturers have been operating as essential industries, though many of their employees continue to work from home. We are prepared to connect you with these companies for timely information about your existing orders or new requirements.

Denning Electronics is committed to providing the exceptional products and services you have come to expect.  We have protocols in place to contain the spread of Coronavirus, COVID-19, and we’re engaging via email, phone, Zoom/other conference service. For critical projects we are making site visits following local protocols.

We track COVID-19 using this dashboard from The Lancet:


The University of Wisconsin Madison has tracked the economic impact of the Coronavirus, and reports it on this website:

These are some of Denning’s products that have a role in containing the spread of infectious disease:

Laboratory and other “clean room” doors (Tiger Door FRP Pharmaceutical Door Series).

Anti-tailgating and door interlock controllers (DSI).

Barrer optical turnstiles with non-contact card readers (DSI).

Perimeter security for laboratories (Southwest Microwave).

Communication infrastructure for portable screening and labs (Vigitron).

Thank you for your continued support!

DSI for Coronavirus Safety updated 9/10/20

A turnstile’s role is to allow only those persons properly vetted to proceed. In security applications turnstiles are a force multiplier for a security operation. In a safety environment they are a force multiplier for screeners, who may do their work remotely out of harm’s way. DSI turnstiles and anti-tailgating systems have for example been used with temperature screening equipment (For COVID-19), PPE (such as facemask and hard hat) detection, electrostatic discharge equipment, and more conventional security screening equipment such as metal and radioactive material detectors.

While DSI has systems suited for high volume high security facilities we have gear equally well suited for public buildings, banks, data centers, industrial sites and sports venues where the new norm will be to safety screen all who enter the property.

DSI relentlessly focuses upon reliability, security, and throughput. This video taken at ISC West in 2018 shows throughput for DSI’s 831 series barrier optical turnstile:

This is throughput for the 880 series turnstiles:

Most barrier optical turnstile projects have a custom element. Do you need extra heavy duty service? Do you need to match the lobby decor? Are you working with a tight space? If you have a tailgating problem, it might make sense to have a conversation with us. No pressure, no cost.

The “NetObserver FreeRun Training” Webinar will cover a special version of
NetObserver that does NOT require network connections or connected devices. Topics Overview:
a. Review of Vigitron’s Network Monitoring Systems
b. How to Evaluate Network Performance Prior to Installation
c. How to Adjust Connected Products for Maximum Performance
d. How to Monitor Your Network
e. How to Quickly Locate and Repair Problems in Your Network

This session is offered on Wed, Sep 23, 2020 1PM PST/4PM EST with a repeat on Wed, Sep 30, 2020 9 AM PST/12PM EST

NetObserver is a next generation health monitoring Windows™ based software capable of receiving status messages from up to 240,000 ports using TCP, UCP, Syslog and SNMP communications. NetObserver recognizes network connected devices by means of Onvif, UPnP and also allows for manual entry. 

Why health monitoring? Large and small security systems with IP CCTV cameras, intercoms, and access control devices must be dependable. Unlike IP phones or other common devices powered by PoE, high power and high bandwidth PoE security devices often have different component states. Outdoor day/night cameras and LED lighting have power requirements that vary by day and by season, so a PoE switch with an inadequate power budget is prone to fail. NetObserver’s GUI with email notification traces the problem, making it easier to quickly respond.

A built-in mapping feature accounting for both IP-enabled network and edge devices ensures manageability, while custom messaging pinpoints trouble.

The Application Programming Interface used to manage the database is Microsoft’s SQL Server Compact 4.0, which is automatically included in the NetObserver installer.

If you’re an integrator, contractor, or security dealer, we’re here to show you how NetObserver works, and guide you to a Vigitron product distributor.

Is There More to Perimeter Security than Video? – Part 2

It’s been over a year since we posted comparing sensor-based perimeter security to video-based outdoor intrusion detection systems. Has anything changed?

The security market is video-centric. We get it – CCTV is a good tool, and it keeps getting better. Every year hundreds of firms plow millions of dollars into CCTV R & D, and millions more are invested in mobile platforms such as drones and artificial intelligence and its integration with security systems. Video is arguably the most visceral security tool available, exceeding even “eyes on” assessment since systems are capable of collecting and displaying information we cannot see (think thermal and IR imaging of the invisible).

If your system has been designed and installed right and everything’s working properly, video addresses what happened and when it happened. With improved internet connectivity you now may have the means to see what’s happening now, and remotely intervene when a crime is taking place. Using high tech tools under ideal circumstances you may even identify a perpetrator.

Denning has sold over $200 million of physical security, communications, and network products* over the past four decades, and we’ve learned crime often doesn’t happen under ideal circumstances. We appreciate layered systems using tools such as CCTV, intrusion detection, communications, access control, and screening that together mitigate an enterprise’s vulnerabilities.

There’s no substitute for for starting with a physical security risk assessment (RA) followed by a vulnerability assessment (VA). The RA outlines the threats, while a VA shows under what circumstances assets are at risk. The VA will also outline and perhaps quantify the potential impact.


Some situations add Deter, Deny, Assess, Communicate, and Intervene to address a particular vulnerability. We do so understanding ASIS International ESRM (Enterprise Security Risk Management) models and tools.

If you’ve determined it’s people you’re trying to find, consider the environment. Even the best lighted perimeters with low light/no light video technologies may be compromised if there’s blowing sand or snow, and/or fog. At a minimum you should be considering a layered “defense in depth” approach, with physical and electronic systems providing enhanced protection for the times when conditions are bad.

As outside reps for leading industry manufacturers, we have field experience with scores of sensors and systems.

It is with this insight that we repeat what we wrote last year: many of our clients once felt that video was their best line of outdoor perimeter defense. Video was chosen to tell them how something happened, and who did it. It takes one incident to tell them they need more than video alone can provide.

Vigitron and Infrastructure

Vigitron solves Ethernet networking problems. The big three are:

It’s too expensive to get Ethernet and power to SIP phones, cameras, intercoms, or access control readers.

It’s too far for Cat 5/6 Ethernet.

Edge devices aren’t reliably powering-up, or they fail when things like heaters kick-in.

There’s a whole compliment of tools to test edge devices and monitor networks.

In 2020 there will be a new line-up of switches and components aimed at the industrial market, Vigitron will be providing PoE Ethernet over untwisted conductors, and hardened smart switches with ring topology that ensure high reliability.

Dealers and integrators: ask us about project registration!

If you’re an integrator that’s helped designed a project around Denning manufacturers, we should be talking.

We represent manufacturers that appreciate the commitment it takes to get larger infrastructure, transportation, institutional, and enterprise projects of the ground. If you’ve invested time there may be a registration reward program for you.

We at Denning have provided surveillance and detection systems for bridges (though as far as we know, not for this particular bridge just south of Ping Tom Park in Chicago). Southwest Microwave is being used to detect ships and prevent bridges from closing on them as move along the Illinois river.

Recap – ASIS International Chicago Global Security Exchange 2019

ASIS International’s Global Security Exchange – GSX – was an extraordinary networking and training event as well as trade show. We regret there will not be an in-person event in 2020, though we plan to attend future events whether in-person or virtual.

It was a shear pleasure working with a great Host Committee as we greeted and answered questions from hundreds of attendees. Moreover, we learned a lot from the vendors and clients that shared what they are doing in this industry. Thanks to all of you for a great show!

Did you miss us? If so, we will probably be in your area soon, so please call to arrange a visit.
