  As an internet-dependent system, any interruption in connectivity might hinder real-time data access and updates, potentially affecting decision-making based on live data.
• Ongoing Costs
  While the hardware installation is straightforward, businesses may incur ongoing subscription fees for continued access to cloud-based services and analytics features.
