How does G-Guard work?

G-Guard uses highly sensitive sensors to measure the heat radiated by people. An approximate thermal cloud is identified and assessed – at a resolution too low to register body parts or gestures.

What is the reach and coverage?

The reach is approx. 5-6 metres. This can be somewhat reduced in very warm rooms. The corners of a room are also covered (near to 180°).

Does it emit radiation?

No. G-Guard is purely passive in contrast to radio wave and ultrasound based systems or devices that emit infrared radiation. Even the radio modules that call for help in an emergency are only switched on in the case of an alarm, in so doing keeping normal electricity consumption to a minimum.

What about obstructions?

G-Guard measures infrared radiation emitted by human bodies completely passively without emitting any energy itself. However, G-Guard can’t measure through walls or around corners as, in the same way as with light, obstructions throw shadows. An unobstructed view of the room is therefore necessary. Large objects that stand in the way can impair image capture. Smaller obstructions such as low tables don’t normally cause any problems.

Can pets disrupt G-Guard?

Standard size pets don’t cause any problems. They’re small enough to be reliably filtered out of monitoring.

How many devices do I need in my flat and why isn’t one enough?

As explained in the previous point, G-Guard works optically, so to speak. That means that in order to detect a fall, G-Guard must have an unobstructed view of what’s happening in the entire flat. Imagine this: you move into a new flat and of course expect adequate lighting in all rooms. Would you expect what has been described as ‘lighting’ to already be installed in the rooms and infrastructure or would you be happy if the landlord just gave you a torch? This is just as it is with conventional home emergency call systems. They must always be at hand for manual activation but unfortunately this isn’t always possible. It’s therefore our view that G-Guard should be an integral part of a flat – and not just simply held in the hand.

Does G-Guard have to be operated while it’s running?

No. Absolutely no interaction is necessary. G-Guard works independently and 24/7.

Is G-Guard safe?

Yes. The radio modules are turned off in normal operation. G-Guard is therefore as vulnerable to attack as a normal light switch – that is, not at all. The device can only be configured by physically accessing it. Personal sensor data never leaves the device.

Is there an app?

No. An app isn’t required. G-Guard works completely independently and sends alarms via SMS and/or voice calls.
