As artificial intelligence becomes mainstream in security systems, many CCTV vendors now offer cameras with built-in AI capabilities—such as motion detection, people counting, or vehicle recognition. While this seems like a convenient all-in-one solution, businesses must carefully evaluate whether it’s truly the best option for their needs.

At Grep Tech, we believe the smarter path is through a centralized Edge AI NVR system—like our GT-AiVision, powered by NVIDIA Jetson. Here’s how it compares to AI-enabled cameras.

1. Flexibility: One Size Doesn’t Fit All

AI Cameras:

  • AI models are often fixed and built-in at the time of manufacture.

  • Limited room to upgrade or add new detection types (e.g., loitering, overcrowding, restricted zone alerts).

  • Difficult to standardize if different camera brands/models are used.

 

GT-AiVision:

  • AI logic is run on a local edge server, not inside the camera.

  • Easily upgrade software and add new AI functions as needs evolve.

  • Works with any standard RTSP camera, regardless of brand or model.

 

Our solution grows with your needs.

2. Cost Consideration: Smart ≠ Cheap

AI Cameras:

  • Generally much more expensive than standard IP cameras.

  • Upgrading an entire facility means replacing every existing camera—significant capital cost.

 

GT-AiVision:

  • Use your existing cameras—no need to replace hardware.

  • Centralized AI processing reduces overall hardware investment.

  • Only one AI box (Jetson Orin Nano or AGX) required per site or per set of streams.

 

💰 Reduce total cost of ownership with our modular edge AI approach.

3. Maintenance & Management: Simpler is Better

AI Cameras:

  • Managing firmware and AI updates across dozens or hundreds of cameras is a nightmare.

  • Each device might require individual access or configuration.

 

GT-AiVision:

  • All AI logic and configuration is managed in one place—via a centralized web dashboard.

  • Easier to audit, configure zones, manage alerts, and review events.

 

⚙️ Less effort. More control.

4. Compatibility with Legacy Infrastructure

AI Cameras:

  • Cannot be retrofitted into older systems easily.

  • Forces businesses to scrap working cameras and NVR setups.

 

GT-AiVision:

  • Designed to complement existing CCTV/NVR systems.

  • Add intelligence without disrupting your current investment.

 

🔄 Bring your old cameras into the AI era—without ripping them out.

Final Thoughts

While AI cameras may look attractive on paper, they often lock businesses into rigid ecosystems, high hardware costs, and limited flexibility. In contrast, GT-AiVision offers a future-proof, scalable, and cost-effective way to enable real-time AI video analytics—without replacing your entire camera infrastructure.

If you’re a security provider, system integrator, or smart building operator—now is the time to explore how GT-AiVision can transform your existing CCTV setup into a modern AI-driven system.
