Ⅰ. Summary
ST-700 Portable wireless video transmission equipment is an excellent all aspects of
performance are more varieties, and its large power margin, small current consumption，normal
operation power is only about 500mA。Small size，Long transmission distance，more suitable
for complex physical environment。While used 0dB omni antenna ( original small antenna)，It
can transmission about 500m in the open air, and block in the general case about 100 to 200m
transmission distance. The product design ideas in this paragraph is mainly targeted at the
needs to carry, inconvenience exposure situations.
It is very small, ease to
clip on the waist
