Surveillance cameras with motion sensors can be used both indoors and outdoors. The type of motion sensor used in the camera determines its suitability for indoor or outdoor use. Passive Infrared (PIR) sensors are commonly used in indoor cameras as they detect changes in heat signatures, while outdoor cameras generally use more advanced motion sensors such as microwave, ultrasonic or dual-tech sensors, which can detect both heat signatures and movement. Outdoor cameras are often designed to be weatherproof and can withstand harsh weather conditions like rain, snow, and extreme temperatures.
It is important to choose a camera with the appropriate motion sensor for the environment in which it will be used. A camera with an indoor motion sensor may not function optimally outdoors, and vice versa. Before purchasing a camera, it is important to check the specifications and features to ensure it is suitable for the intended use.
