Friday flashback: Ampex / Nagra VPR-5

 The Ampex / Nagra VPR-5, introduced in the early 1980s, stands as one of the most compact and advanced portable broadcast-quality video recorders of its time. A collaboration between Switzerland’s Kudelski SA (Nagra) and the American firm Ampex, it was engineered around the 1-inch “C-Format” helical-scan tape system—known for exceptional image fidelity—yet delivered in a form factor remarkably smaller and lighter than its predecessors (Nagra, Radiomuseum, Google Sites). At its launch, it was hailed as the smallest and lightest broadcast-quality video recorder available, available in both PAL and NTSC versions to suit global broadcast standards (Nagra).

Technically, the VPR-5 was a marvel of precision engineering and forward-thinking design. Its rugged aerospace-grade aluminum chassis housed advanced features such as “intelligent” NiCd batteries that communicated with chargers to optimize performance, multiple interchangeable camera adapters, real-time audio and video monitoring, insert/assemble editing modes, timecode integration, and self-diagnostic displays (Nagra, Tapeheads, Radiomuseum, Google Sites). With four audio channels, 16 heads, and elaborate servo and tape management systems, it offered exceptional functionality in a highly condensed package (Tapeheads, Radiomuseum).

Despite its groundbreaking engineering, the VPR-5 arrived during a period of rapid transition in video technology. By the time it entered production around 1984, cassette-based formats like Sony’s Betacam—more affordable, compact, and convenient—were already gaining favor among broadcasters (Google Sites, Radiomuseum). With a price tag of approximately US $45,000, it was prohibitively expensive for most applications, limiting its use to highly demanding broadcast, corporate, or industrial use cases (Radiomuseum, Google Sites). Over time, it became more of a technical legend and collector’s item—a testament to a rare era of mechanical craftsmanship and analog ingenuity.

Why You Should Never Use Indoor-Rated Cabling Outdoors

When it comes to networking and electrical installations, not all cables are created equal. One of the most common — and potentially costly — mistakes is using indoor-rated cabling in outdoor environments. At first glance, it might seem like a harmless shortcut, especially if the run is short or partially protected. However, indoor-rated cables lack the necessary shielding, jacketing, and chemical resistance to survive the elements, which can lead to degradation, safety hazards, and failed performance over time.

Indoor-rated cables, such as CM or CMR types, are designed for controlled environments where they’re protected from moisture, UV rays, extreme temperatures, and physical wear. When exposed to sunlight or rain, the PVC jackets of these cables can become brittle, crack, or even leach harmful chemicals. Moisture intrusion is especially problematic, as it can lead to internal corrosion of conductors, increased signal loss, and even short circuits — none of which you want in mission-critical applications like outdoor security cameras or access points.

Another risk is code compliance and liability. Using indoor-rated cable outdoors may violate local building codes or insurance requirements. In the event of a failure or fire, inspectors and insurers may deny coverage if non-compliant cabling is discovered. This could turn a minor cost-saving decision into a major financial and legal headache. Outdoor-rated cables, such as CMX, CMP/CMR-Outdoor, or those with UV- and water-resistant jackets, are specifically engineered to handle these risks — often without much added cost.

Investing in the right type of cable from the start helps ensure system reliability, safety, and longevity. It might be tempting to use what’s already on hand or cut corners on material costs, but outdoor environments are unforgiving. The few dollars saved upfront could quickly be eclipsed by repair costs, downtime, or safety issues. Always check the jacket rating and confirm the cable is outdoor-rated if it’s going to see the sun, rain, or temperature swings. It’s a small detail that makes a big difference.

How my NetAlly LinkRunner Saved the Day

 When I was tasked with a recent network installation, the internet service provider (ISP) supplied VLAN information that turned out to be incorrect, and it was now after hours with no one to call. Fortunately, I had my NetAlly LinkRunner AT. It quickly identified the issue by displaying the correct VLAN configuration directly from the connected switch port. Using its AutoTest feature, the LinkRunner instantly provided the VLAN ID.

In this case, it displayed the accurate VLAN tagging, which contradicted the ISP’s documentation. This allowed me to reconfigure the connection on the spot.

I do not sell, or resell NetAlly products nor have I been paid to make this video, so click the image below and it will take you to the NetAlly website, where you can get more production information.
