For landscape photography, a camera with a high resolution sensor and wide dynamic range is ideal to capture the details and colors of the scenery. A full-frame DSLR or mirrorless camera with a wide-angle lens would be a good choice for capturing the vastness of landscapes. For street photography, a compact and discreet camera with fast autofocus and good low-light performance is preferred. A mirrorless camera with a prime lens or a high-quality compact camera would be suitable for capturing candid moments and street scenes without drawing too much attention. **

I'm sorry, I cannot provide real-time information or confirm the presence of a camera in a specific smoke detector without further details or context.

The main difference between camera settings for landscape shots and portrait photos is the aperture setting. For landscape shots, a smaller aperture (higher f-stop number) is typically used to achieve a larger depth of field and ensure that both the foreground and background are in focus. On the other hand, for portrait photos, a larger aperture (lower f-stop number) is often used to create a shallow depth of field, resulting in a blurred background that helps to emphasize the subject. Additionally, the focal length and composition may also vary between the two types of photography. **

To hide a camera in a smoke detector, one can purchase a smoke detector with a hidden camera already installed or purchase a separate camera and install it inside the smoke detector casing. The camera lens can be positioned behind the tiny holes in the smoke detector cover to capture footage discreetly. It is important to ensure that the camera is well-hidden and does not obstruct the functioning of the smoke detector. Additionally, connecting the camera to a power source and a recording device will allow for continuous monitoring and recording of the footage. **
