Bullet cameras also have impact-resistant housing made with robust materials like polycarbonate or metal. These materials can withstand drops and impacts. The tough build and weatherproofing ensure the camera will not rust or corrode.
• Remote Viewing and Mobile Access: Remote viewing and mobile access allow users to view bullet cameras from anywhere. Bullet cameras offer convenient and secure mobile access to surveillance footage. Buyers can choose cameras with Remote Viewing Systems (RVS). The system comes with an app or software that allows access to live feeds and recorded footage.
• Audio Monitoring and Analytics: Bullet cameras have audio monitoring features that allow users to listen to areas being monitored. The cameras have built-in microphones for recording audio on a linked device. Audio monitoring helps ascertain what happened during an event. Cameras with audio recording also help capture spoken evidence that can be used in court. Bullet cameras offer video analytics that help detect events or objects for effective surveillance. They may include features like motion detection that alerts users when something passes the camera's view. People detection distinguishes a person from an inanimate object, while facial recognition can identify faces. The camera can provide alerts when it sees someone whose face matches the stored data.
