Method and system for a trail camera with modular Fresnel lenses
A cellular trail camera system is disclosed and includes a housing; a mounting bracket for mounting the camera; a visible sensor; an infrared sensor; and a plurality of Fresnel lenses each operable to be individually mounted to or with the infrared sensor and to focus infrared light to the infrared sensor from a different direction. One of the Fresnel lenses may be mounted to or with the housing during operation. The housing includes a wireless transceiver, which may communicate via a cellular network. The camera may communicate with a wireless communication device via the wireless transceiver. The camera may communicate images and/or video to the wireless device. The infrared sensor may include a plurality of elements. The camera may be powered by a solar cell that is mounted on the camera or remote from the camera. The visible sensor may be activated when the infrared sensor detects a heat-generating object.
1 . A camera system, comprising:
a plurality of lenses, wherein each lens has a respective angle-of-view; and
a camera comprising a visible light sensor, a visible lens operable to provide the visible light sensor with a visible field-of-view, an infrared sensor, and a lens mount operable to mount one of the plurality of lenses to the camera so as to direct infrared light in the angle-of-view of the mounted lens to the infrared sensor, wherein the camera is operable to capture images in the visible field-of-view of the visible lens with the visible light sensor in response to motion detected based on the infrared light the mounted lens directs to the infrared sensor.
2 . The camera system of claim 1 , wherein the camera is further operable to:
present the visible field-of-view of the visible light sensor; and
present a visual depiction of the angle-of-view for the mounted lens in relation to the visible field-of-view of the visible light sensor.
3 . The camera system of claim 2 , wherein:
the camera comprises a wireless transceiver operable to receive a code that identifies the mounted lens; and
the camera is operable to present the visual depiction of the angle-of-view for the mounted lens based on the received code.
4 . The camera system of claim 2 , wherein the camera is operable to present the visual depiction of the angle-of-view for the mounted lens as an overlay over an image captured by the visible light sensor.
5 . The camera system of claim 3 , wherein the wireless transceiver is operable to communicate via a cellular network.
6 . The camera system of claim 3 , wherein the camera is operable to present the visual depiction of the angle-of-view for the mounted lens to a wireless device via the wireless transceiver of the camera.
7 . The camera system of claim 6 , wherein the camera is operable to communicate images captured by the visible light sensor to the wireless device.
8 . The camera system of claim 1 , wherein the infrared sensor comprises a plurality of elements.
9 . The camera system of claim 1 , comprising a solar cell coupled to the camera and operable to power the camera.
10 . The camera system of claim 1 , wherein at least one of the plurality of lenses is a plastic Fresnel lens.
11 . A method of remote imaging, the method comprising:
mounting a lens of a plurality of lenses to a camera, wherein each lens has a respective angle-of-view, and wherein the angle-of-view of the mounted lens corresponds to a desired angle-of-detection;
directing, with the mounted lens, infrared light in the angle-of-view for the mounted lens to an infrared sensor; and
capturing images with a visible light sensor of the camera in response to motion detected by the infrared sensor based on the infrared light that the mounted lens directs to the infrared sensor.
12 . The method of claim 11 , comprising:
presenting a visible field-of-view of the visible light sensor; and
presenting a visual depiction of the angle-of-view for the mounted lens in relation to the visible field-of-view of the camera.
13 . The method of claim 11 , comprising:
scanning a code that identifies the mounted lens; and
identifying the mounted lens and its angle-of-view based on the scanned code.
14 . The method of claim 11 , comprising:
receiving, with a wireless transceiver of the camera, a code that identifies the mounted lens; and
identifying, with the camera, the mounted lens and its angle-of-view based on the received code.
15 . The method of claim 11 , wherein presenting the
presenting an image captured by the visible light sensor; and
presenting a visual depiction of the angle-of-view for the mounted lens as an overlay over the image captured by the visible light sensor.
16 . The method of claim 15 , comprising wirelessly transmitting the image captured by the visible light sensor and the visual depiction of the angle-of-view for the mounted lens to a wireless device.
17 . The method of claim 11 , comprising wirelessly transmitting images captured by the visible light sensor to a wireless device.
