Self-leveling mount
Camera Remote Controller

When ordered as a complete system, WinSCANOPY is much easier to use. A system comprises the following components (some of which are optional):

Digital camera and a fish-eye lens  

The cameras and lenses we sell range from low cost point-and-shoot cameras with a fixed fish-eye lens to high-end digital single lens reflex (DSLR) cameras with an interchangeable fish-eye lens.

When purchased from Regent Instruments, cameras and lenses come with a calibration file that indicates to the WinSCANOPY program:
1) the position and radius of the 180 degree field of view hemispherical area to analyse in the image.
2) the calibration coefficients for non-linearities compensation in the image projection.
3) miscellaneous information about the camera (image size, aspect ratio…) and lens (Model, FOV…).

You can also provide the calibration parameters of your own camera and lens. Note that this require some technical knowledge about these components and that Regent Instruments does not provide any help for this (we sell complete systems to avoid doing this).

Self-leveling mount  

A self-leveling mount, called O-Mount because of its round shape, holds the camera at horizontal level during image acquisition. Automatic leveling saves time and reduces risk of manipulation errors. O-Mounts are made of robust plastic and are offered in varying weights and sizes.

The DSLR version comes with the SunBlocker. It prevents the direct sun rays from reaching the camera fish-eye lens, thus eliminating glare. It can be installed and removed in few seconds.

The DSLR version can also be used in nadir view (downward looking image acquisition) for gorund cover analyses (Pro version required).

  O-Mounts with North Finder and Mini-O-Mount. There is a standard attachment hole for easy mounting on standard mono or tripod. Note: Tubular handle is not included but you can use selfie sticks or compact monopods (with a ¼ 20 screw thread).  

The NorthFinder is an option for the O-Mount that indicates in the image the magnetic north direction around the camera fish eye lens in real time. It illuminates a small LED light close to the fish-eye lens in the north direction.

A calibration procedure must be done once in a while by the user. This calibration, which takes a few seconds, cancels out perturbations to the Earth's magnetic field caused by nearby objects (camera, mount, ...).

Camera Remote Controller  
The Camera Remote Controller allows to trigger the camera at distances up to 25 or 75 meters (depending on the model and canopy density). It is the ideal solution for acquiring images in forest canopies at different heights. Even at ground level, you will appreciate the ease of use compared to the camera's built-in timer. We offer different models, some use IR and works only a few feets away and does not allow for any obstruction between it and the camera, while others operate on radio waves that are not affected by ambient light or canopy. These can be operated from behind the camera and works even when obstructed by tree branches and leaves.

The Camera Remote Controller is comprised of a very compact remote control (similar to those used to unlock car doors) and a shutter-presser controller that is installed close to the camera on the O-Mount.
