摘要： A system of capturing thermal images in a monitored location, comprising one or more motion detectors for detecting a motion in a monitored location, the one or more motion detector being a thermal motion sensor, and a thermal imaging sensor, operating in a low power mode, triggered by a motion detection indication to enter an operational mode in order to capture one or more thermal images of at least a part of the monitored location. The motion detection indication is generated by the one or more motion detectors at a detection of a motion in the monitored location.

摘要： In a monitoring system, each individual camera device divides image data acquired by an image sensor unit into a plurality of areas, and detects video-image abnormality from an average luminance signal value in each area or from a change thereof. The camera device that has detected video abnormality transmits video-image abnormality detection information to a server. In the plurality of areas, it is possible to use different detection algorithms such as a first algorithm in which it is determined that an abnormality has occurred when there is no change in the average luminance value, a second algorithm in which it is determined that an abnormality has occurred when there is a change in the average luminance value, and a third algorithm for observing a change in the video captured while a change is made to an aperture, exposure time, or the like.

摘要： The present invention relates to a method of monitoring a moving object in video images, comprising:
- receiving a plurality of video images from the video system;
- defining in the video-images at least one gate having sides forming a closed loop, the loop including at least:
- a first side;
- a second side opposite the first side; and
- one or more further sides arranged between the first and second sides so as to define the extent of the gate;

- tracking the moving object in the video-images;
- generating a signal indicating that a tracked object has passed the gate on the condition that a) the moving object has crossed one of the first side and the second side of the gate; b) the moving object has temporarily stayed inside the gate; and c) the moving object has crossed the opposite side of the gate.

摘要： A security system (20) includes at least one camera (22) that provides a reference image regarding an area within a field of vision (24) of the camera (22). A controller (30) determines whether a difference between at least a portion of a test image obtained by the camera (22) and a corresponding portion of the reference image indicates tampering with the camera. Disclosed examples detect a variety of tampering conditions and provide an indication of camera tampering so that corrective or preventative measures may be taken.

摘要： Disclosed are a warning generation method and a security system using edge detection of a video image signal. The warning generation method includes the steps of : a) decoding video image signals and extracting luminance signals from the decoded video image signals; b) filtering high-frequency components of the extracted luminance signals and detecting edge components within the video image signals; c) extracting only values within a range of a predetermined first threshold value form the detected edge components; d) accumulating the detected edge components for one video image; and e) operating a warning device if an accumulation value is smaller than a predetermined second threshold value. When an intruder blinds a camera lens using a cover, the security system can generate a warning by identifying the fact that the camera is blinded by the cover.

摘要： The invention relates to a method for detecting motion in a scene, characterised by the following steps: (a) determining two chromatic values (H1, H2) of a scene point by measuring the brightness (H1i, H2i) of the point in at least n different spectral regions at two different times, where n is an integer number ≥2, (b) determining a first and a second vector (h1, h2) in an n'-dimensional vector space, for the two chromatic values, by means of measured brightness values (H1i, H2i), where 2≤n'≤n, (c) determining the distance of the end point of the second vector (h2) to a straight line defined by the first vector (h1), and (d) deciding that motion occurred when the distance exceeds a predetermined threshold value (ε). The invention also relates to a device for implementing such a method. Considering that the brightness values are taken into account and related to different spectral regions, the existence of motion in the scene can be evaluated more safely than when the overall scene brightness is observed in visible light.
