Abstract: A pre-record data storage device includes: a first recorder; a second recorder having a capacity larger than that of the first recorder; a face comparison processor that executes a face comparison process on a person's face detected from an image obtained by photographing the person; and a recording controller. The recording controller allows the first recorder to start pre-recording of the image of the person from a face detection time when the person's face is detected, and to finish the pre-recording at a matched time when matching is confirmed as a result of the face comparison process of the face comparison processor. The recording controller stores pre-recorded data from the face detection time to the matched time in the second recorder.

Abstract: A video recording method includes: detecting an intrusion of a person into a predetermined monitoring area based on the video information from the monitoring camera; recording the intrusion time when the intrusion of the person into the monitoring area is detected; detecting a left-behind object after the person has passed through the monitoring area based on the video information from the monitoring camera; generating alarm information in response to the detection of the left-behind object; overwriting so as to record the video information by every given amount of information until the alarm information is received. The method further includes receiving and recording, of the video information recorded in the first video recording step, video information from the intrusion time of the person to a time corresponding to the alarm information in accordance with the intrusion time of the person in a case in which the alarm information is generated.

Abstract: A pre-record data storage device includes: a first recording unit; a second recording unit having a capacitance larger than that of the first recording unit; a face comparison process executing unit that executes a face comparison process on a person's face detected from an image obtained by photographing the person; and a recording control unit. The recording control unit allows the first recording unit to start pre-recording of the image of the person from a face detection time when the person's face is detected, and to finish the pre-recording at a matched time when matching is confirmed as a result of the face comparison process of the face comparison process executing unit. The recording control unit stores pre-recorded data from the face detection time to the matched time in the second recording unit.

Abstract: In a monitoring system, a plurality of monitoring devices for performing a sequence operation of sequentially switching images output from a plurality of cameras are connected. Each of the monitoring devices includes: an address information collection unit configured to collect address information of other cascaded monitoring devices when the sequence operation of an own device is started; a storage unit configured to store the address information collected by the address information collection unit; and a command transmission unit configured to determine a next address from the address information stored in the storage unit and to transmit a command for starting the sequence operation to one of the other monitoring devices which has the determined next address when the sequence operation of the own device is terminated.

Abstract: An object of the invention is to provide an image record apparatus and an image record method that can improve the use efficiency of a record medium for recording a video image from a camera. A NW control section (141) acquires the image quality and the resolution set in a camera (10) performing pre-record and calculates the maximum image size that can be transmitted by the camera (10), and a file system (142) calculates the number of images from the preset pre-record rate and pre-record time and reserves an area corresponding to the maximum image size of one pre-record image calculated by the NW control section (141) in an HDD (146). The NW control section (141) records a pre-record image transmitted from the camera (10) in the area reserved by the file system (142). When it records as many pre-record images as the number of pre-record images, it returns to the beginning of the area reserved by the file system (142) and continues recording a pre-record image is continued.

Abstract: A removal/abandonment determination device includes: a sampling point setting unit configured to set sampling points on a boundary line of an object; a luminance determination unit configured to determine whether a ratio of an area having the same luminance in a peripheral region of each of the sampling points is a first certain value or more; and a removal/abandonment determination unit. The removal/abandonment determination unit determines that the object is removed when the sampling points of which the ratio is determined as being the first certain value or more are a second certain value or more, and determines that the object is abandoned when the sampling points of which the ratio is determined as being the first certain value or more are less than the second certain value.
