Some more info,
They claim being able to transmit 1W at 1 meter, hunderds of mWs at 2m and 10s of mW at 5m, but when asking a bit more details, this was for an unspecified receiver size, unspecified transmitter model and unknown alignment.
When they demo the system, they hold the receiver with fingers blocking parts of the beam, but not the white square. I assume this means it's at least safe enough so that it does not hurt.
The receiver they demo is not delivering measurable power (2 wires you can connect to a meter, or some USB you can connect to a phone) instead it has an array of approximately 14x16 red LEDs which are not very bright to look at. When it's working, only about a 1/3 of the LEDs are lit. Assuming the LEDs are 5mW LEDs, this would be translated to about 350mW of usable power at short distance.
The demo kit includes a slightly smaller receiver, approximately half the size.
The kit includes the small transmitter, which does not lock on receivers but rather has a fixed focus and is always on.
During conversation they said that
All components of the kit are commercially available and ready to go to production.
Its completely safe, when asking about Israel (demo was in Israel) they avoided the question.
They said it's certified as safe by a 3rd party, they avoided answering who is the 3rd party.
They avoided all questions about dBs in either side (transmitter or receiver).
