The lifespan of Blink cameras can vary based on usage and environmental factors. Typically, Blink cameras are designed to last for several years. Battery-powered models can last anywhere from 2 to 4 years on a single set of batteries, depending on usage and settings. Wired models can last longer if they are well-maintained. Regularly changing the batteries and protecting the cameras from extreme weather conditions can help extend their lifespan. However, technological advancements and product updates may influence the longevity of Blink cameras over time.
