The range of night vision on a hidden camera can vary depending on the model and specifications. Generally, most night vision hidden cameras can capture clear footage in low light conditions up to a range of 15-25 feet. However, some high-end models can have a range of up to 50-100 feet. It is important to check the specifications of the camera before purchasing to ensure it meets your specific needs and requirements. Additionally, factors such as the placement of the camera, the amount of ambient light, and the presence of obstacles can also affect the range of night vision.
