Dahua 4MP 25x Zoom PTZ valvontakamera<\/h2>\n

Dahua SD49425GB-HNR\u00a0PTZ IP valvontakamera tehokkaalla 25 optisella zoomilla. PTZ valvontakamera mahdollistaa laajan alueen valvonnan tehokkaasti yhdell\u00e4 kameralla. PTZ ominaisuudet mahdollistavat kameran vaaka- ja pystyk\u00e4\u00e4nn\u00f6n sek\u00e4 optisen zoomin k\u00e4ytt\u00e4misen. Kameraa voidaan ohjata et\u00e4n\u00e4 esim. valvontakameraj\u00e4rjestelm\u00e4n tallennusyksik\u00f6lt\u00e4 tai et\u00e4hallintaohjelmistojen kautta (tietokoneella ja \u00e4lypuhelimilla).<\/p>\n

SMD Plus, teko\u00e4lyynpohjautuva liiketunnistus<\/h3>\n

Kameran uusi SMD plus ominaisuus perustuu teko\u00e4lyn syv\u00e4oppimisalgoritmiin jonka avulla kamera osaa suodattaa kuvassa tapahtuvasta liikkeest\u00e4 erikseen ihmisen ja ajoneuvon aiheuttaman liikkeen. T\u00e4m\u00e4n avulla virhe tallennuksen v\u00e4henev\u00e4t perinteiseen kameraan verrattuna ja h\u00e4lytykset ovat entist\u00e4 tarkempia ja aiheellisempi.<\/p>\n

PTZ valvontakamera<\/h3>\n

PTZ- nimitys valvontakameralle tulee sanoista pan, tilt ja zoom. N\u00e4ill\u00e4 tarkoitetaan k\u00e4\u00e4nt\u00f6\u00e4, kallistusta ja zoomausta.<\/p>\n

Kamera mahdollistaa siis tehokkaan 360 asteen valvomisen yhdess\u00e4 valvontakameralla.<\/p>\n

PTZ- valvontakamera tunnetaan my\u00f6s nimill\u00e4 ohjattava valvontakamera ja k\u00e4\u00e4ntyv\u00e4 valvontakamera.<\/p>\n

WDR- Wide Dynamic Range – toiminto<\/h3>\n

Valvontakameran WDR toiminto parantaa ja selkeytt\u00e4\u00e4 kuvan valotusta.<\/p>\n

Tasoittamalla kuvan valotusta se himment\u00e4\u00e4 ylivalottuneita kohtia ja parantaa pimeiden kohtien valotusta.<\/p>\n

Ominaisuuden ansiosta esimerkiksi suoran auringon paisteen aikana saadaan hyv\u00e4laatuista ja tasaisesti valottunutta videokuvaa.<\/p>\n

H.265 videopakkaus<\/h3>\n

H.265 videopakkausstandardi pakkaa ja kuluttaa kaistaa jopa 50% v\u00e4hemm\u00e4n kuin aikaisempi videopakkausstandardi.<\/p>\n

T\u00e4m\u00e4 s\u00e4\u00e4st\u00e4\u00e4 tallennuslaitteen kaistankulutusta ja kiintolevytilaa huomattavasti sek\u00e4 parantaa samalla j\u00e4rjestelm\u00e4n kustannustehokkuutta.<\/p>\n

Kamera kest\u00e4\u00e4 tarvittaessa \u00e4\u00e4riolosuhteetkin<\/h3>\n

Dahua\u00a0SD49425GB-HNR valvontakamera toimii \u00e4\u00e4rimm\u00e4isiss\u00e4kin olosuhteissa. K\u00e4ytt\u00f6l\u00e4mp\u00f6tila jopa -40 \u00b0C to +70 \u00b0C.<\/p>\n

Valvontakamera suojattu IP66 mukaisesti, jolloin valvontakamera t\u00e4ysin p\u00f6lytiivis ja kest\u00e4\u00e4 joka puolelta tulevan voimakkaan vesisuihkun.<\/p>\n
