Wireless security cameras with built-in NV (night vision), IR (infrared) motion sensors, and heartbeat sensors typically come in several types, including dome cameras, bullet cameras, and PTZ (pan-tilt-zoom) cameras. Dome cameras are often used for indoor surveillance due to their discreet design, while bullet cameras are ideal for outdoor monitoring and can cover longer distances. PTZ cameras offer the flexibility to remotely adjust the camera angle, making them suitable for large areas. The heartbeat sensor adds an additional layer of security by detecting the presence of individuals based on subtle movements, enhancing overall surveillance capabilities.
