Passive Infrared sensor (PIR sensor) is an electronic device that measures infrared (IR) light radiating from objects in its field of view. PIR sensors are often used in the construction of PIR-based motion detectors (see below). Apparent motion is detected when an infrared source with one temperature, such as a human, passes in front of an infrared source with another temperature, such as a wall. This is not to say that the sensor detects the heat from the object passing in front of it but that the object breaks the field which the sensor has determined as the "normal" state. Any object, even one exactly the same temperature as the surrounding objects will cause the PIR to activate if it moves in the field of the sensors.[1]

Having a PIR sensor in a security IP camera is considered as an advanced feature. Maxcom has a range of IP CCTV cameras which come with this feature giving a user a lots of benefits by recording events, sending email, push noticiations, saving images to FTP folder triggered by movements.

One of these cameras is Robocam which has a built-in PIR sensor and pushs notifications to your iPhone, iPad, Andrpid, send alerts to your email and ftp folder. For more info visit http://maxcom.ae/robocam
