Trail cameras can definitely be used for home surveillance. They are often used to monitor the exterior of a home or property and can help to deter potential intruders. Many game cameras have features that are well-suited for home surveillance, such as night vision, motion detection, and the ability to send alerts to your phone or email when activity is detected.
