Diversity system for measuring reception quality

For assistance of the operator who positions a wireless camera (CSF), The radio frequency signal (S) of the good quality transmitted from the transmitter (EC) which the base station (SB) linked to the camera is received, Two or more measurement means (M1*MK) linked to the diversity receiver (R1*RK) of the signal have decided whether the characteristic of the signal through each receiver fulfills the receiving standard (TH), respectively. In a base station, a counter (COM) counts the receiver which fulfilled the receiving standard, a receiving quality indicator (QR) is formed depending on the contented number of receivers, it is resent to a camera through a return channel (VR), and a divider is displayed on the display.
