When I last wrote about the Aurga remote camera controller (see http://www.worldcadaccess.com/blog/2018/06/aurga-remote-camera-controller.html) , it wasn't working. It would not connect to the camera. Aurga tech support promised me that a software update coming soon would fix the problem.
(Aurga is a remote controller that sits in the DLSR's hotshoe, connected to the camera with a USB cable. See figure 1. Their app runs on an Android or iOS device, with which you control the camera remotely via a local WiFi connection.)
The software update turned out to be for the Android app. (I had thought it would be a firmware update to the controller unit.) With the update, the app now connects to the controller, showing me information about the camera, in my case a Nikon D3100. The primary purpose of the app is to control the camera, such as changing settings (shutter speed, aperture, photographic modes) and taking pictures, such as in timelapse and multiple-image modes.
With the app working, I found that several remote functions don't work with the D3100, including the all-important live view. (See figure 2.) Live view is where the app shows on the Android screen what the camera lens is seeing. This one flaw dooms the Aurga. If you can't see remotely what the camera is seeing, then there is no point to the Aurga.
Not only would live view show the image being captures, but also the settings that affect it, such as how bright or dim the image is. There isn't even a non-live live view, such as a one-time static image updated, say, through a refresh mechanism.
A few other Aurga controls also do not work with the D3100.
The Aurga Web site does not list which functions work with which cameras, and so if you purchase a unit, you are gambling it will work as advertised. Unhappily, the site implies that all functions work with all cameras. (See figure 3.) The only hint of a problem is in the corporate blog, in which Aurga staff indicate that they are getting more functions to work on Sony DSLR cameras -- meaning not all functions work with Sonys, either.
I suspect the problem lies in which functions the camera manufacturer makes available via the USB connector, and so Aurga programmers have no control over which functions can be controlled by their app. This problem does not, however, absolve the company of failing to warn consumers of reduced functionality.
Aurga is not the only remote camera controllers on the market.
