These devices can be sorted into two main groups:
James Gentles created a serie of small devices to control camera functions via a regular RC-transmitter or a regular switch. These devices can also be used in combination with the Rig controls in the next chapter.
The Auto Rig Controller wil operate servo's for Tilt, Pan and Shutter on a KAP-rig without user imput. (other than selecting a mode and switching it on..)
It has various programs for panning the camera, panning and tilting the camera and has settings for various interval modes shutter release, ranging from 2 seconds to 4 minutes.
The AuRiCo will work with any major brand standard servo. Depending on the servo's it will operate on 1 lipo cell or 4 AA(A) batteries.
The CAMremote-2A (CR-2A) is highly integrated miniature remote control devices for cameras and camcorders. Several digital cameras/camcorders have a remote control feature which utilizes the USB port, an infrared signal or Remote Control Port.
The CAMremote is an USB On-the-Go device which has USB host and device functionality. It can control the camera's remote features like:
CAMremote has an integrated intervalometer which will trigger the camera automatically after a predefined time. The infrared support of the CAMremote can be used with cameras where no USB remote control feature is available but which have an infrared sensor. The Remote Port support can be used mostly with SLR-cameras which has dedicated port for remote control.
Using Graphical User Interface software which runs on Windows operating systems, CAMremote can store settings for up to seven different camera and/or servo motor configurations. Switching between stored settings is accomplished by pressing an onboard button or remotely using radio control.
DuneCam™ is a portable system for remote control and monitoring of a camera. Although designed for low altitude aerial photography, DuneCam™ can be used in other situations where there is a need to point and trigger a camera remotely.
DuneCam™ simplifies the process of remotely controlling a camera. With its small, highly integrated controller, you can point your camera, trigger the shutter and monitor a video image from up to 1 km (3000 ft) away.
DuneCam™ has three channels of motion control, designed for controlling standard R/C servo motors. The camera's shutter can be triggered by a servo channel, infrared (if your camera supports it) or a switch closure (if your camera supports it). Very powerful remote camera functions are possible for Canon cameras running CHDK.
More work to be done here obviously. I prefer to keep this page as an intro page, with a short explanation for each item, linking to the device's wiki-page with a bit more detailed information.
