The first thing to consider when installing NoahFace for Time and Attendance or other interactive applications is where to physically mount the iPad. Where possible, the iPad should be mounted:
At a location that has constant light during the day (ie: not facing a window).
Either:
Flush to a wall, with the camera eye is between 150cm and 155cm from the ground.
At 130+cm from the ground, angled slightly towards the ceiling.
On a bench, angled even more towards the ceiling.
In portrait orientation, with the camera eye at the top of the iPad.
Securely, so the iPad cannot be moved, tilted, or easily stolen.
Tilting the iPad allows people of varying heights to more easily interact with the iPad. The diagrams below show these possible mounting positions.
The mounting position is extremely important and sets the foundations for good recognition results.
Powering your iPad
Your iPad must be permanently powered by either:
The standard Apple iPad power adaptor, if you have a nearby power point (the standard USB cables are only 1m long).
A higher wattage power adaptor and a USB extension cable.
A power over ethernet (POE) adaptor eg: Belkin Ethernet + Power Adapter with Lightning Connector.
It is imperative that you test your iPad to make sure it retains its full charge when the NoahFace App is running.
A few things to consider:
The standard iPhone charger will not provide sufficient power for an iPad.
The brightness on your iPad screen can impact the power drain if you have it set to its maximum setting.
The zoom setting in the NoahFace App can impact the power drain. Unless it is absolutely necessary, it is recommended to leave the zoom setting (under Camera/Settings) at its default (non-zoomed) setting.
Connecting to your Network
The NoahFace App will continue to work if you temporarily lose your Internet connection, however, you should plan for it to be permanently connected to your network by either:
A Wifi access point.
A power over ethernet (POE) adaptor eg: Belkin Ethernet + Power Adapter with Lightning Connector.
