Security system consists of physical and electronic components for home protection. Key components include cameras, motion sensors, entry sensors, and sirens. Systems can be wired or wireless, smart or local only. Base station connects all devices to mobile app for remote control
RCWL-0516 uses microwave radar to detect moving objects. Operates at 3.18 GHz frequency with 360-degree beam. Detection range up to 7 meters with 2m/s speed capability. Output goes HIGH when motion detected, LOW otherwise
Handheld device combining phone, iPod, and internet functionality. Quad-band GSM capable with 850-1900 MHz frequencies. 3.5" display with 320x480 resolution at 163 ppi. 4GB, 8GB, or 16GB storage options (4GB discontinued, 16GB introduced). Wi-Fi, EDGE, and Bluetooth 2.0 connectivity
Motion Apps library enables sensor processing through Digital Motion Processor. Library readings are faster and more accurate than manual calculations
RCWL-0516 uses microwave and Doppler Effect for motion detection. Unlike PIR sensors, it doesn't rely on heat and works in hot environments. Detects any movement from any object within 5-7 meters range
RCWL-0516 is a microwave proximity sensor using Doppler radar. Operates at 3.18 GHz frequency with 4V-28V DC power supply. Uses very low level of microwave radiation, safe for human use
