A notification that your CCTV camera is offline is a stressful event. If the camera has power and hasn’t been physically damaged, the issue lies in the data connection between the camera and the cloud.
Here are the most common causes of 4G/5G CCTV network dropouts.
1. Network Congestion (The Silent Killer)
If your camera goes offline at the same time every day (e.g., 5 PM), the culprit is local mast congestion. As people return home from work and stream Netflix on their phones, the local single-network mast you rely on runs out of bandwidth. It drops your heavy video stream to prioritize other traffic.
- The Fix: A multi-network SIM from Anywhere SIM will detect this congestion and automatically switch to a less busy mast from a competing network (e.g., jumping from a busy Vodafone mast to a quieter O2 mast).
2. Weather Degradation (Rain Fade)
Heavy rain, snow, and wet foliage physically absorb cellular radio frequencies. A signal that was just strong enough to stream video on a clear day will degrade during a storm, causing the camera to drop offline.
- The Fix: Ensure you are using an external, high-gain directional antenna pointed directly at the mast, and use a multi-network SIM that can switch to lower, more weather-resilient frequencies if needed.
3. Deactivated SIM Cards
If you used a standard consumer Pay-As-You-Go SIM from a supermarket, the network will permanently deactivate it if it hasn’t made a chargeable outbound voice call or SMS in 90 days. Because CCTV cameras only use data, the network assumes the SIM is dead.
- The Fix: Only use dedicated M2M (Machine-to-Machine) business SIMs from Anywhere SIM, which are completely exempt from inactivity deactivations.
