RF-Link's
8-channel A/V module is the foremost design in the 5.8GHz
RF transmission. It is mainly used in the in/outdoor surveillance
camera application, where the feature of 8 RF channels
available for manual selection is quite popular. Especially
with its mini size transmitter module design (only 32mm
x 29 mm), it is perfect to incorporate in covert surveillance,
this make AWM-5890 the best solution provided in OEM/ODM
specialty market.
In
addition, the issue of interference commonly seen in 2.4
GHz home entertainment market is also getting more and
more wide-spreading in the surveillance industry, where
AWM-5890 is strongly immune to such interference.
