A security camera that you cannot view is useless. If you are constantly staring at a buffering wheel and asking, “Why does my CCTV camera keep disconnecting?”, the issue is almost certainly the quality of your cellular connection.
Video streaming is highly sensitive to network instability. Here is why your camera drops out.
1. You Are On the Wrong Network
If you inserted a standard SIM (e.g., Vodafone), that mast might be located behind a hill or a dense block of buildings relative to your camera. The signal is weak, and the moment it drops below a critical threshold, the video stream severs.
2. Mast Congestion
If your camera is near a busy road or in a dense urban area, the local mast handles thousands of users. During peak times, the network deprioritizes heavy data streams (like your 1080p video) to allow voice calls to pass through. This congestion chokes your upload bandwidth, causing the disconnection.
3. The “Breathing” Effect
Cell tower coverage maps “breathe” (shrink) when the tower is busy. A camera on the very edge of the coverage zone might have a signal at 3 AM when the network is quiet, but drop completely offline at 9 AM when the network gets busy and the coverage radius shrinks.
The Permanent Fix
Stop trying to force a single network to do a job it cannot handle. By upgrading your camera’s router to an unsteered Anywhere SIM, you eliminate these issues.
Our multi-network SIM actively monitors the connection. If the Vodafone mast becomes congested and throttles your video stream, the SIM will instantly initiate a handover and connect the camera to an EE or O2 mast with clearer bandwidth. The result? A rock-solid, continuous video stream.
