Specialized switches yekubatanidza IP makamera
Kupfupisa zvese zviri pamusoro, tinogona kutaura kuti kushanda nehurongwa hwakavakirwa
IP makamera ari nyore kana ukashandisa midziyo yakanyatsogadzirirwa
kushanda navo. Uye sezvo IP makamera akabatana kune switch, pazasi pane kutaura
Ngatitaure nezvezvishandiso zvemhando iyi.
Kuchinja kwakadaro, mabasa anotevera anobuda:

Kudzora Kwepamusoro kweVhidhiyo Kuongororwa
Kuti uwane iyo yakakwana, inoenderera yekutarisa, pamwe neye
nyore kushandisa, Zyxel yakawedzera zvinhu zvitsva zvinobatsira:
- ruzivo nezve IP kamera pane peji re "Vavakidzani";
- kutarisa mamiriro ekhamera;
- isina kukanganiswa magetsi ekupa kamera (kana uchigadziridza kana kudzoreredza switch);
- kure reboot ye IP kamera;
- granular PoE sarudzo yekutsigira isingaenderane IP kamera
