1. An integrated security arrangement, comprising:

  • an intrusion sensor to sense an intrusion at a target area of a facility;

    a self-powered detection device including;

    a second sensor to sense movement;

    a non-Alternating Current (AC) power source;

    an image-capture device to capture images in response to an intrusion indication from the intrusion sensor and to a movement indication from the second sensor;

    an electronic circuit to control power drawn from the non-AC power source by the second sensor and the image-capture device, the electronic circuit, in response to receiving an intrusion indication from the intrusion sensor, increasing power drawn from the second sensor by arming the second sensor and, in response to receiving a movement indication from the second sensor, increasing the power drawn from the image-capture device by arming the image-capture device; and

    a base unit, powered by the non-AC power source, integrating the electronic circuit, the non-AC power source second sensor and the image-capture device, and directing the second sensor to sense in the target area in which the images are captured by the image-capture device.
