Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Further features, effects and advantages of the invention emerge from the following description of a preferred exemplary embodiment of the invention, and from the attached figures. Here, respectively in a schematic diagram:

[0052] FIG. 1 shows a camera device in accordance with the invention and

[0053] FIG. 2 shows a time sequence for logging onto the data network from FIG. 1.

DETAILED DESCRIPTION

[0054] FIG. 1 shows a camera device 2 for an exterior region 4 of a building 6, of which only a wall 8 is indicated. The camera device 2 is installed on an exterior side of the wall 8, and hence in the exterior region 4 of the building 6, at an intended installation position. The camera device 2 contains a camera 10 for producing image data 12 (depicted symbolically) of surroundings 14 of the camera device 2. The camera device 2 contains a network module 16, indicated symbolically, for connecting the camera device 2 to a data network 18, which is likewise symbolically indicated and is a Wi-Fi or WLAN here.

[0055] FIG. 2 shows a temporal sequence of the following events: the camera device 2 contains an evaluation module 20 (indicated symbolically) which is configured to detect a code pattern 22 in the image data 12 from a predetermined start time ts to an end time te if such a code pattern 22 is captured by the camera 10. In the example, the code pattern 22 is held in front of the camera 10. If a code pattern 22 was successfully recognized, the evaluation module 20 subsequently detects an authorization code 24 and access data 26 for the data network 18 in the code pattern 22. If an authorization code 24 and access data 26 were recognized, the detected authorization code 24 is checked in terms of the validity thereof. In the case of a valid authorization code 24, the camera device 2 is logged on to the data network 18 with the aid of the access data 26. The time of a successful logon is set as end time te.

[0056] By way of example, the start time ts is a time of a restart of the camera device 2.

[0057] However, the start time ts may also be the time of logging the camera device 2 off the data network 18. From such a start time ts, only the authorization code 24 which was transferred for the preceding logon to the data network 18 is accepted in a subsequent authorization procedure.

[0058] The camera device 2 contains a first light source 30 which serves to produce target illumination in the surroundings 14 of the camera device 2. A path not depicted in FIG. 1 is illuminated as a target, said path leading past the wall 8 of the building 6. The camera device 2 contains a second light source 32; a corresponding light source 32 is furthermore also situated at the lower side of the camera device, this not being visible in FIG. 1. The light source 32 serves to produce ambient lighting 34 in the surroundings 14 of the camera device 2. The ambient lighting 34 is merely indicated symbolically in the form of two light cones projected against the wall 8. Thus, the surroundings 14 are not illuminated directly by the light sources 32; instead, an optically appealing effect is obtained on the wall 8 as a result of the ambient lighting 34. The camera device 2 moreover contains a motion detector 36 for detecting a movement of an object (not depicted here) in the surroundings 14 of the camera device 2. The generation of image data 12 is started when a movement is detected.

[0059] The evaluation module 20 contains an interface 38 to a counterpart 40 in the form of a partner program. The connection to the counterpart 40 is brought about by way of the data network 18 along the symbolically depicted dashed line in FIG. 1. Here, the counterpart 40 is an app of a smartphone.

[0060] The camera device 2 moreover contains a loudspeaker 42 and a microphone 44, which are not visible in FIG. 1 as they are hidden behind a perforated grating in the interior of the depicted housing of the camera device 2 and are therefore merely indicated symbolically. In the camera device 2, an intercom function from the surroundings 14 to a counterpart 40 in the form of the partner program is brought about with the aid of the loudspeaker 42 and the microphone, as indicated symbolically by a dashed connection.

[0061] A total of three objects 15a-c are situated in the surroundings 14, namely a tree 15a, a rabbit 15b and a human 15c. All the objects 15a-c are moving. The motion detector 36 recognizes the movement of all three objects 15a-c. Thereupon, the camera 10 is activated and said camera starts recording or producing image data 12. The latter image the three objects 15a-c.

[0062] The evaluation module 20 is configured to detect the objects 15a-c in the image data by program-technical motion detection. Since the program-technical motion detection also identifies the movement of all three objects 15a-c, the movement detection by the movement detector 36 is validated. The latter therefore detected correctly.

[0063] However, now a classification of the objects 15a-c in the image data 12 is additionally carried out. In so doing, the object 15a is classified as a plant, the object 15b is classified as a small animal and the object 15c is classified as a human. Since plants are generally considered to be irrelevant by the evaluation module 20, the object 15a is classified as irrelevant. This does not lead to an alarm being triggered at the counterpart 40. However, small animals and humans are generally considered relevant by the evaluation module, and hence the objects 15b,c are initially classified as potentially relevant.

[0064] Now, further differentiation is carried out: the objects 15b,c are situated in a region 17 of the surroundings 14. This region 17 also corresponds to an image portion of the image data 12. Small animals are likewise considered irrelevant in this region as a so-called small-animal suppression is carried out. Thus, the object 15b likewise does not lead to an alarm being triggered at the counterpart 40. However, the human 15c is considered relevant even in the region 17. Since said human moves, an alarm is triggered at the counterpart 40. A user (not depicted here) can now observe the respectively current image data 12 transferred to the counterpart 40 at the latter. Moreover, the aforementioned intercom function facilitates communication with the human 15c.

[0065] A schedule for operating the first light source 30 and the second light source 32 is set in the evaluation module 20. Said schedule is introduced by the counterpart 40. The light sources 30, 32 are switched on and off according to this schedule. The operation of the light sources 30, 32 also depends on a brightness value of an ambient light in the surroundings 14, with the brightness value being ascertained by an ambient light sensor 46 in the camera 10.

[0066] Moreover, the light sources 30, 32 are dimmed by the evaluation module 20. The corresponding prescriptions are provided by the counterpart 40.
