Shielded Mobius Case Now Available;
Based on input from a number of users in the RC (Radio Control) and Cycling markets; along with testing, we have decided to offer a shielded version of the Mobius camera. We are also offering the shielded camera housing and buttons for those that already have a Mobius camera.
Who Needs it:
Anyone using their Mobius in conjunction with another piece of electronics that may be susceptible to interference from RFI. At current, these seem to be devices that rely upon use of GPS systems; i.e. some remote control vehicles, cycling computers, navigation systems to name a few.
The video shows a side by side test of a typical UN-shielded Mobius along with a totally shielded version of the Mobius. The test on the video was performed using an Android GPS App on a GalaxyS4 phone. Actual field tests were also conducted with known problem RC vehicles and also in the cycling market where individuals were using GPS devices. Both have yielded positive results. When viewing the video, pay attention to the (3) areas circled in Red. (GPS Status, Accuracy & Bar Graph showing satellites in view and strength) Note that the “GPS status” 3D Fix drops out, “accuracy (in feet)” goes way up, and “bar graph” loses all satellites for the UN-shielded camera, but not with the shielded camera. The dramatic impact of this can change based on devices, day, location, indoors vs outdoors, cloud cover, etc.
About Shielding (the basics):
EMI/RFI (Electromagnetic Interference/Radio Frequency Interference) shielding is used to keep undesirable signals from either getting out or into a device. These signals can cause undesirable effects on the device itself or to other devices in close proximity or in the area. In simple terms, it can be thought of in relation to light. If you had a box or container that you didn’t want to have light get into or out of, you wouldn’t make it from a material that is translucent and you would want to minimize the amount of openings that the light could enter. So in the case of shielding, there needs to be an electrically conductive cage encompassing the device. Typical plastics are non-conductive and therefore don’t make for good shielded enclosures. If we could, the ideal case for the camera would be made from some sort of “metal” (ferrous or non ferrous) material; i.e. Copper, Aluminum, Steel, Lead, Brass, Nickel, etc.
What we are offering:
Our shielded Mobius consists of a special metallic coating on the inside of the housing along with the buttons. When these parts are used together, they yield the results seen in the video above by creating the electrically conductive cage mentioned above; thereby making those other devices unaffected by use in conjunction with and in close proximity to the Mobius. As mentioned, the Mobius looks the same other than the Pewter color can can also be seen when looking at the gap between the case halves.
