(*) CODFM: Coded Orthogonal Frequency Division Multiplex

OPTIONS / RANGE
R1000 may work independently of the electricity network by means of solar power

As an option, up to 4 cameras may be connected to one transmission link

With minimal effort, mobile use of the system with perfect transmission quality, covering a range up to 5000 m can be achieved. 25 km with fixed installed transmission routes are possible
