Abstract

In an observation system, comprising an observation camera (A, B, C, D), and an observation monitor unit (CU, M) coupled to the observation camera (A, B, C, D), upon the occurrence of a for observation purposes relevant event (doorbell DB) a plurality of preferably sub-sampled images including an image at a time of the event are recorded and a sequence (E) formed by the plurality of images is repeatedly displayed.

Claims

1. An observation system, comprising:

an observation camera (A, B, C, D); and

an observation monitor unit (CU, M) coupled to said observation camera (A, B, C, D);

characterized by;

means (DB, WCD) for detecting a for observation purposes relevant event; and

wherein

said observation monitor unit (CU, M) comprises;

recording means (REC) for recording a plurality of images including an image at a time of said event;

means (M) for repeatedly displaying a sequence (E) formed by said plurality of images upon said event.

2. An observation system as claimed in claim 1, wherein said plurality of images includes images preceding said event.

3. An observation system as claimed in claim 1, wherein said sequence is displayed in PIP form (E).

4. An observation system as claimed in claim 1, wherein in the case of multiple events, a sequence including a latest of said multiple events is repeatedly displayed.

5. A method of observing a complex, the method including:

using at least one observation camera (A, B, C, D) and an observation monitor unit (CU, M) coupled to said at least one observation camera (A, B, C, D);

characterized by;

detecting (DB, WCD) a for observation purposes relevant event;

(CU) a plurality of images including an image at a time of said event; and

repeatedly displaying (M) a sequence (E) formed by said plurality of images upon said event.

6. An observation monitor control unit (CU), comprising:

means for receiving camera signals (A, B, C, D);

means for receiving event detection signals (DB, WCD) indicating a for observation purposes relevant event;

means (REC) for recording a plurality of sub-sampled images including an image at a time of said relevant event to repeatedly supply a sequence formed by said plurality of sub-sampled images.
