Important note:

The tables provide the approximate maximum distances with a tolerance of approximately ± 50m.

The distances may vary according to the wire quality also when the latter is made by the same
manufacturer as the devices.

Consider that the distances may decrease if the devices are used with DVR apparatuses.
