A modular floodlight system comprising: a floodlight device comprising: a main housing having a generally cylindrical shell with a central axis intersecting opposing first and second ends of the main housing ; first and second light subassemblies (106-1, 106-2) connected to the main housing at lateral sides of the shell that are substantially parallel to the central axis , the main housing positioned between the first and second light subassemblies (106-1, 106-2), each of the first and second light subassemblies (106-1, 106-2) including a light housing ; and a passive infrared, PIR, lens positioned on a side of the main housing and between the first and second light subassemblies (106-1, 106-2), the PIR lens having a dome shape that houses multiple PIR sensors configured to detect motion of an object within a field of view of the multiple PIR sensors , the modular floodlight system being characterized by: a magnet mount assembly attached to the first end of the main housing , the magnet mount assembly including: a front surface defining a plane that is non-orthogonal to the central axis of the main housing ; and a magnet providing a magnetic force configured to act on a metal part of a modular camera device to magnetically secure the camera device to a magnet mount , wherein: the light housings of the first and second light subassemblies (106-1, 106-2) each have a general cylindrical shell with a rounded cap; and the dome shape of the PIR lens protrudes from the side of the main housing . a main housing having a generally cylindrical shell with a central axis intersecting opposing first and second ends of the main housing ; first and second light subassemblies (106-1, 106-2) connected to the main housing at lateral sides of the shell that are substantially parallel to the central axis , the main housing positioned between the first and second light subassemblies (106-1, 106-2), each of the first and second light subassemblies (106-1, 106-2) including a light housing ; and a passive infrared, PIR, lens positioned on a side of the main housing and between the first and second light subassemblies (106-1, 106-2), the PIR lens having a dome shape that houses multiple PIR sensors configured to detect motion of an object within a field of view of the multiple PIR sensors , the modular floodlight system being characterized by: a magnet mount assembly attached to the first end of the main housing , the magnet mount assembly including: a front surface defining a plane that is non-orthogonal to the central axis of the main housing ; and a magnet providing a magnetic force configured to act on a metal part of a modular camera device to magnetically secure the camera device to a magnet mount , wherein: the light housings of the first and second light subassemblies (106-1, 106-2) each have a general cylindrical shell with a rounded cap; and the dome shape of the PIR lens protrudes from the side of the main housing . a front surface defining a plane that is non-orthogonal to the central axis of the main housing ; and a magnet providing a magnetic force configured to act on a metal part of a modular camera device to magnetically secure the camera device to a magnet mount , wherein: the light housings of the first and second light subassemblies (106-1, 106-2) each have a general cylindrical shell with a rounded cap; and the dome shape of the PIR lens protrudes from the side of the main housing . the light housings of the first and second light subassemblies (106-1, 106-2) each have a general cylindrical shell with a rounded cap; and the dome shape of the PIR lens protrudes from the side of the main housing . <EOS>
