Smart Devices Can Catch Fire: What You Need to Know

Smart home devices, much like mobile phones, carry a rare but present risk of catching fire, primarily due to their rechargeable batteries. Issues with lithium-ion batteries, common in wireless security cameras and video doorbells, can lead to thermal runaway. This occurs when internal battery chemicals overheat, expand, and ignite, a process that can be worsened by external heat.

While such incidents are infrequent and affect a small fraction of devices, manufacturers have recalled models to address fire hazards. For instance, Ring recalled certain video doorbells in 2020, and Wyze recalled solar cameras in 2026 due to battery issues. These recalls, coupled with improved product design and quality control, have made device fires less common in recent years.

To mitigate risks, consumers should inspect devices for battery damage, swelling, or unusual heat. It's advisable to keep battery-powered products away from extreme heat and avoid charging them on heat-trapping surfaces. Always use genuine batteries and ensure devices have the latest firmware updates. Regularly checking for product recalls from security brands is also a crucial step in maintaining device safety.
