Root Causes of Zosi Live View Buffering

Buffering can occur for several reasons, including:

  • Weak Wi-Fi signals: Poor signal strength (below -80dBm) can cause buffering, especially in older UK homes with thick walls.
  • Outdated firmware: Old firmware versions may lack performance optimizations.
  • Network congestion: Too many devices on the same network can slow down your camera’s connection.
  • Incorrect Wi-Fi band: Using 5GHz instead of 2.4GHz can reduce signal penetration.
  • Faulty hardware: A damaged Ethernet cable, PoE switch, or camera component can cause buffering.

UK-specific challenges, such as dense construction materials and limited Wi-Fi penetration, can also contribute to buffering issues. Always ensure your camera is placed in a location with strong Wi-Fi coverage for optimal performance.
