Access Control and Surveillance as IP Infrastructure
Access Control and Surveillance as IP Infrastructure
Devices and Applications in the corporate environment have become increasingly IP-based. The IP which used to be always there on the backend, at the integration level, is finding a place in front end user application as well. The simplicity and familiarity to configure are the two main reasons which drive the IP adoption.
The recent two new applications, which were traditionally non-IP or non-IT, are access control and surveillance, to be added to IP Infrastructure. Both these applications are beside whatever have already transformed like voice communication (SIP Now), Storages, Wireless access etc. Access control and Surveillance, both these devices used IPs; only in the head-end side where the storage media or controllers are connected to the network infrastructure. Today CCTV cameras and the access controller up to the sensor level, are IP enabled and ready for deployment as part of the IT infrastructure.
These changes have been gradually happening for the last 10 years. Because of the ubiquitous nature of IP in the infrastructure, it is logical for any manufacturer to adopt IP for their applications to be part of the infrastructure. All the Low voltage applications, including the Industrial Automation, will morph or change to IP Infrastructure
Designing the IT/OT Reference Architecture using Purdue Model for Manufacturing and Energy
Most industrial networks were not designed; they accreted. A switch added for a new line, a router dropped in for the warehouse, a remote site bolted on with whatever connectivity was available that month. The result works until it has to be secured, audited, or...
Total Cost of Ownership of a Rugged Industrial Firewall: Hardware, Subscriptions, Support and Lifecycle
The purchase price of an industrial firewall is the part of its cost that is easiest to see and least likely to surprise you. The expensive surprises live elsewhere: in the recurring security subscriptions, in the support tier, in the firmware policy that quietly...
OT Security That Doesn’t Break Production
The defining constraint of operational-technology security is that you usually cannot do the obvious thing. You cannot patch the PLC, because patching means downtime and downtime means lost production or a tripped safety system. You cannot reimage the twelve-year-old...
Connectivity at the Edge
An unmanned solar farm, a remote pumping station, or a mine perimeter has a problem an office never has: there may be no wired internet, and there is no one on site to reboot a router when the link drops. For these sites the WAN is cellular, and the quality of the...
Sizing the Rugged Firewall to the Plant
A rugged firewall series usually spans a dozen variants that look almost identical on a shelf and behave very differently in the field. The catalogue lists them by performance tier, but performance is rarely what decides the right model for an industrial site....
Reading an Industrial Firewall Datasheet Without Getting Burned
A firewall datasheet is a sales document dressed as an engineering document. Every number on it is true, and almost every number is also optimistic. For office IT that rarely matters. For an industrial buyer specifying a device that will sit in a substation, a mine...
Rugged Devices: Conformal Coating & Ingress and Industrial Electronics
Rugged Devices Industrial Environments demand Hardware that can withstand Extreme Temperature, Dust, Moisture and Vibration. Rugged devices/ Appliances for Networking, Security and shop floor HMIs or PCs are engineered for such environment to prevent costly downtime,...
The Manufacturing Network Upgrade Plan: Segmentation, Industrial Switching, Wi‑Fi, and Zero Trust for the Factory Floor
Modern manufacturing is highly IT driven, with most applications and equipment now IP networked, with little or no manual intervention. The traditional environment of machines, conveyors, and operators has evolved into connected robotics, real-time dashboards,...
From Ad-Hoc to Audit-Ready: Modernizing Legacy Manufacturing Networks in India (IT + OT + Compliance)
Many manufacturing networks in India evolved organically over the years—one unmanaged switch added for a new production line, a Wi-Fi router dropped in for the warehouse, and a few “patch-and-go” fixes to keep downtime low. While these decisions made sense at the...
IoT / OT/ Industrial Firewalls vs Enterprise Firewalls
For a very long, the firewall was a singular concept. Placed at edge of a network, inspected packets, blocked suspicious traffic, and allowed business applications to function. Whether protecting a corporate LAN, data center, or branch office, the same category of...
