Abstract: The present disclosure provides a camera assembly and an imaging apparatus. The camera assembly includes a camera body and a front cover. The front cover defines a receiving space. An end portion of the camera body is at least partially mounted in the receiving space. A snap-fit structure is provided at a junction between the camera body and the front cover. The snap-fit structure includes an elastic snap-fit member and a plurality of snap grooves arranged peripherally. When the elastic snap-fit member engages with different snap grooves, the camera body is positioned at different angles relative to the front cover. After the camera assembly of the present disclosure is fixed to the substrate, the angle of the camera body can be adjusted directly via the snap-fit structure without needing to detach and realign the entire camera assembly, which allows users to mount and use the camera assembly more conveniently and efficiently.

Abstract: The present disclosure a camera assembly. The camera assembly comprises an imaging module and a first connecting member. The first connecting member is connected between the imaging module and a first side of the light-transmitting substrate. The first connecting member defines a first light-transmitting hole and includes a light shielding portion. The first light-transmitting hole is corresponded to a camera lens of the imaging module. The light shielding portion is set around the first light-transmitting hole and protruded from a peripheral surface of the imaging module. The imaging module is configured to image a scene on a second side of the light-transmitting substrate through the first light-transmitting hole. A side of the imaging module back from the first connecting member is a third side. The light shielding portion is configured to block light rays from the third side, so as to avoid a problem of imaging glare.

Abstract: A hand-cranked photovoltaic mobile integrated trailer and a power system thereof, comprising a monitoring and lighting assembly, a lifting rod assembly, a chassis frame assembly, an adjustable photovoltaic assembly, a power system, and a storage box, wherein the monitoring and lighting assembly is placed at a top portion of the lifting rod assembly and comprises monitoring cameras, a lighting fixture, a sound amplification device, and a cloud computing data processing control box; the adjustable photovoltaic assembly comprises a photovoltaic bracket, photovoltaic panels, and a hand-cranked photovoltaic rotating support used to adjust support angles of the photovoltaic panels; the power system is installed in an electrical box and comprises a battery energy storage assembly, an MPPT controller for photovoltaic access, an AC/DC controller for mains power access, a DC/DC voltage stabilizing controller for supplying power to the monitoring and lighting assembly, and a DC/AC controller for emergency power supply.
