Hey there, FergalB.
The short answer would be, Yes it will. The Nest Cam with floodlight’s camera has a single motion sensor, with 110° horizontal field of view. Motion can be detected from up to 25 ft (7.5 m) away. The floodlight has 2 motion sensors, with a 180° horizontal field of view and motion can be detected from up to 25 ft (7.5 m). All Nest cameras use high-power infrared (IR) LEDs. Nest Cam with floodlight uses 6 high-power 850 nm infrared LEDs and can illuminate a scene that’s up to 20 ft (6.10 m) away.
