About Us

About us

A leading supplier of Commercial Technology products direct

Pro Telecom Supply was created in the Spring of 2009 to build on the legacy and quality support of Penfold Electrical Service Founded in East Aurora, NY in 1954 by the Penfold Family. After several decades of providing support and Service to customers, the Penfold Family led by Dr. Josh Penfold created an online resource for customers to find quality telecom and data products bundled with exceptional support. With a strong heritage of unsurpassed commitment to customers, we are dedicated to making sure your project has the tools you need, when you need it. 


What is Wholesale Direct?


Wholesale direct means we ship either direct from the Manufacturer or one of our stocking warehouses direct. This means we do not ask for time consuming applications or accounts in order to source the industries best products. Whether you are an installer, Internal IT Department, or even a savvy end user, we make sure you have access to the parts you need, when you need it.

Many of our competitors either provide no support or charge markups of 40,50, and even 80% above cost. With our direct model, you get great support from our US based team and pricing with markups generally below 10%. With our large purchasing power we get you the best deals and ensure you only get 100% non grey market products. 

Our Promise:

We will offer the #1 Value in Telecomunications and Security to you, the customer,
consistently, every day on every product we sell.

At Pro Telecom Supply, we took common sense ideas and applied them to the IP Telecom and Security market to create the premier Superstore online. We designed the business around our promise: ”Low prices, fast shipping, award-winning service.” It all adds up to the #1 Value in the industry.


Quality Products

You have a broad choice of quality products
at your fingertips

Whether putting together a system from design phase or maintaining equipement at your location, we give you an alternative to traditional "big company" suppliers. In most cases, spec for spec, we have a product in-stock that you can use at a lower price, backed by our highly rated FREE service, ready to ship the day you order it.

Our brand named products come from companies such as Mobotix, DSC, POS-X,UTC, HID, Ruckus Wireless, Altronix and more. We also private-label (from several major manufacturers) many popular products and have some custom-designed to our customers'needs.


Value Priced

Get more for your money with value priced products
that help you maximize your budget

Our prices are well below the list price of other, more traditional Commercial Products companies. Those companies probably have lower manufactured costs, but they operate with much higher overhead. With our direct business model and focus on efficiency, Pro Telecom Supply has the lowest overhead in the industry. That’s why we can offer high-quality products at lower prices. With many traditional companies selling to trade only, and with the convergence of the IP products industry, we make sure you the Installer or DIY end user have accesss to the best products in the industry.
