Ukukhululwa kwephrojekthi ye-Frigate 0.14 kuyatholakala, ukuhlinzeka ngamathuluzi okudala amarekhodi evidiyo enethiwekhi (i-NVR, i-Network Video Recorder) ehlaziya ividiyo edluliswa kumakhamera okuqapha we-IP ngesikhathi sangempela, kanye nokubona nokurekhoda izinguquko nezinto. Isibonelo, isistimu ingagcina izithombe zabantu abadlula ikhamera. Ukuze kukhonjwe izinto, kusetshenziswa imodeli yokufunda yomshini, eyenziwa kusistimu yendawo ngaphandle kokufinyelela kumasevisi angaphandle. Ikhodi yesikhulumi ibhalwe ngePython futhi isatshalaliswa ngaphansi kwelayisense ye-MIT.
I-OpenCV ne-Tensorflow zisetshenziselwa ukucubungula izithombe ezithunyelwa ngekhamera nokuhlonza izinto. Uhlelo lwenzelwe ukusetshenziswa okuncane kwezinsiza futhi lisebenzisa imodeli yokwethulwa yezinqubo eziningi. Ukuze unciphise umthwalo, ukutholwa kwento kwenziwa kuphela ngokuhambisana noshintsho nokutholwa kokunyakaza. Ukuhlanganiswa nezinhlelo ezihlukahlukene ezishintshayo zasekhaya ezisekela iphrothokholi ye-MQTT (Message Queuing Telemetry Transport), njengomsizi Wasekhaya kanye ne-OpenHab, kungenzeka. Ukulawula kwenziwa ngesixhumi esibonakalayo sewebhu, esingahlanganiswa ngokuqondile kusixhumi esibonakalayo Somsizi Wasekhaya.
Phakathi kwezici ezishiwo yizinga eliphansi lezinto ezingamanga, ikhono lokuhlonza izinto ngokwehlukana (abantu, izimoto), ukusekelwa kokusetshenziswa kokuzithandela kwamadivayisi we-Google Coral TPU ukusheshisa ukucubungula ividiyo ngesikhathi sangempela (i-Frigate ingacubungula into engaphezu kwe-100 imisebenzi yokuhlonza ngomzuzwana), ikhono lokunquma izindawo zokubangela kanye nesikhathi esiqondile sokuhlasela, isistimu eguquguqukayo yokuthumela izexwayiso. Uhlelo futhi lusekela ukudluliswa kwevidiyo nokubukwa bukhoma kusetshenziswa i-WebRTC ne-RTSP, okunciphisa inani lokuxhunywa kukhamera.
Ukukhishwa okusha kuyaphawuleka ngokungezwa kwesixhumi esibonakalayo somsebenzisi esisha, esibhalwe kabusha ngokuphelele esilungiselelwe ideskithophu kanye nezinhlelo zamaselula. Isixhumi esibonakalayo sikuvumela ukuthi uhlole ngokushesha isimo samanje futhi ufunde izehlakalo ezisanda kwenzeka, uthole ukufinyelela bukhoma ezithombeni zekhamera, ubuke isimo sesifinyezo samakhamera futhi ulandelele umlando wemicimbi, ekhonjiswa ngokucacile ngesimo sezithonjana ezipopayi. Ukwesekwa okwengeziwe kokuqinisekisa, okuchaza izindima zokufinyelela (umlawuli, umsebenzisi) nokuxhuma kusetshenziswa ama-proxi anjenge-authelia, i-authentik ne-oauth2_proxy.
Isixhumi esibonakalayo sokubuyekeza ividiyo erekhodiwe sithuthukisiwe, lapho manje ungakwazi ukushintsha ngokushesha phakathi kwezikhathi lapho ukunyakaza kuqoshwa khona nezinto ezikhonjwa ngazo. Izehlakalo ezihlonziwe zihlukaniswe ngezigaba zokubaluleka nezinhlobo zezinto, futhi ikhono lokuhlunga ngokusekelwe ezintweni eziza kuqala liye lanezelwa (isibonelo, isimo somuntu owela umugqa wendawo sibaluleke kakhulu kunokuhlonza umuntu ohamba eduze). Ikhono lokuhlukanisa amakhamera abe amaqembu seliqalisiwe.
