Are you delaying your CCTV upgrade because of costly and messy power wiring?
The security landscape is rapidly moving towards High Definition, but many businesses are stuck. The hurdle? The costly, disruptive process of replacing old coaxial cables with Ethernet and installing separate power lines for every new camera. The shift to HD shouldn't require ripping out your existing infrastructure. Analog HD (AHD, TVI, CVI) offers a powerful middle ground, and when paired with PoC (Power over Coaxial) technology, it dramatically changes the upgrade game.
Learn how PoC with Analog HD cameras dramatically cuts installation time and budget, delivering stunning HD quality without the traditional complexity of IP systems.
HD Video and Power, All in One Coax Cable
PoC (Power over Coaxial) is a game-changing feature for Analog HD systems. It represents a significant technological leap in coaxial cable transmission.
Unlike traditional Analog HD setups, which required the camera's video signal to run through the coaxial cable while demanding a separate, dedicated power supply line (often requiring an outlet near the camera), PoC allows the power to be transmitted directly over the existing coaxial cable alongside the video signal.
This innovation simplifies the installation process down to a single point of connection. This means you can upgrade your old analog cameras to the latest high-definition models without the hassle or expense of running a single new power line. It offers the Plug-and-Play simplicity that installers and system integrators crave.
The 3 Critical Advantages: Why PoC Drives Down Total Cost of Ownership (TCO)
For any business decision-maker, the value proposition must translate into measurable savings and efficiency. PoC delivers tangible ROI through three core benefits:
1. Massive Cost Reduction: Eliminate Separate Wiring Costs
Eliminating the need for a power outlet and separate electrical cabling at every camera location is the most immediate financial benefit. This not only saves on material costs but significantly reduces the labor hours required for installation. Case studies show that adopting PoC technology can slash overall installation costs by up to 30% compared to traditional powered setups, making HD surveillance accessible to businesses with strict budgets or legacy wiring.
2. Seamless & Faster Upgrade: True Plug-and-Play
For legacy sites already wired with coaxial cable, PoC enables a true, hassle-free HD upgrade. The process is simple: disconnect the old analog camera, connect the new PoC-compatible Analog HD camera, and plug it into a compatible PoC DVR. No electrician needed to run power. This speed minimizes operational disruption, particularly critical in active retail, industrial, or manufacturing environments.
3. Simplified Maintenance and Reliability
With only one cable serving dual purposes (video and power), troubleshooting becomes significantly faster, reducing system downtime. Furthermore, centralized power management at the PoC DVR or recorder inherently offers better protection against power surges and simplifies the integration with Uninterruptible Power Supplies (UPS), ensuring greater system resilience during outages.
Is PoC Right For Your Next Project?
If your project involves upgrading an existing surveillance system that uses coaxial infrastructure, or if you are looking for a reliable HD solution with the simplest possible wiring, PoC is the most efficient, cost-effective, and practical choice. It eliminates complexity without compromising on the high-quality resolution (up to 5MP) that modern security demands.
Ready to See the Difference PoC Makes?
Stop letting complex wiring hold back your security upgrade. PoC technology is the smartest, most budget-friendly path to high-definition surveillance using your current coaxial infrastructure.
