5. AMANOTHI OKUSETSHENZISWA
· ✅ Yakhelwe ukuhlanganiswa ezinhlelweni zokusakaza eziphuthumayo ezihlakaniphile, isekela ukuvula okukude nge-4G cloud platform (isb., “Emergency Broadcast Cloud” noma i-MQTT/HTTP API yangokwezifiso).
· ✅ Isekela ukunqamula okubalulekile: ukufaka komakrofoni > ukufaka kolayini > ukudlala kwe-MP3 (uma kuxhunywe isidlali sangaphandle).
· ✅ Ijubane lefeni lishintsha ngokuzenzakalelayo ngokuya ngezinga lokushisa langaphakathi — ukusebenza okuthulile ngaphansi komthwalo olula.
· ⚠️ Ungasebenzisi ngaphandle kokuthi kufakwe i-grounding efanele. Sebenzisa i-circuit breaker ezimele (okungenani u-16 A).
· ⚠️ Imoduli ye-4G idinga i-SIM card evumelekile enedatha futhi icushwe kahle i-APN.
