IP kamere za video nadzor

Pri gledanju televizijskih novic, poslušanju časopisov ali pogovorov z ljudmi verjetno ne traja več kot nekaj dni, ne da bi se slišali za ropanje, ropanje ali drugo nezakonito delo, ki je bilo storjeno. Nato dneve ugane, kdo je lahko in kaj se je točno zgodilo.

V naši državi video nadzorni sistemi niso tako prisotni, da so takšni dogodki neopaženi in postali "nevidni". Video nadzor je eden od načinov za zmanjšanje verjetnosti, da se vam bo to res dogajalo. Če niste prepričani, kakšen je videonadzor in kaj lahko preberete na našem spletnem mestu za video nadzor in vse, kar morate vedeti .

Ko gre za video nadzorne sisteme, je zastarelo analogno video nadzorni sistem in sodobnejši IP video nadzor . Na podlagi novejših in boljših rešitev bomo se osredotočili na kamere. Spodaj bo naša tema IP kamere, kot tudi nekatere splošne stvari, povezane z IP video nadzorom.

Pojdimo ...

Kaj je IP video nadzor?

IP video nadzor je sistem video nadzora, kjer je mogoče gledati slike ali gledati prenos v živo prek omrežja (LAN ali internet). To je velika prednost te vrste video nadzora, saj nam daje mobilnost in spremlja situacijo na oddaljeni lokaciji.

IP video nadzorni sistem mora vsebovati vsaj eno kamero IP, kabli, ki kamere povežejo z NVR, napajalni kabli, NVR (snemalniki) z ustreznim trdim diskom za shranjevanje video materiala. Prav tako zahteva, da monitor ali televizor predvaja posneto video material. Programska oprema za snemanje in shranjevanje slik je še en element, ki ga ne smemo pozabiti. Na računalnik se lahko priključi tudi računalnik, na katerega se bo posnela posneto gradivo.


Shema IP video nadzora

IP video nadzor ima veliko prednosti pred analognimi. Kakovost posnetih video materialov je višja, saj so IP kamere veliko boljše kot analogne in imajo boljšo ločljivost.

Zmožnost ogleda materiala preko omrežja ali celo življenja na njem je velika prednost. Potem  možnost PoE napajanja je kamera, ki varčuje denar, čas in energijo.

IP video nadzor in IP kamere imajo številne prednosti pred analognimi

  • Nižja cena celotnega sistema s povečano funkcionalnostjo, saj IP omrežje ponuja veliko možnosti
  • Več možnosti pri izbiri programske opreme in strojne opreme za snemanje videa na odprtokodne datoteke
  • Možnost velikega prihranka v kablov , zlasti na večjih sistemih. Na primer z uporabo CAT5e namesto koaksialnega kabla RG-59
  • Preprostost in prihranek stroškov z uporabo PoE , zmožnost napajanja fotoaparatov preko istega kabla, ki se uporablja za prenos podatkov
  • Prenos nadzorne ukaze na PTZ kamero preko istega kabla
  • Sposobnost opozarjanja po elektronski pošti ali na drug način, ko zazna gibanje v okviru
  • Obstaja podpora za inteligentno zaznavanje gibanja , natančnejše prepoznavanje oblik, štetje predmetov, ljudi ali vozil
  • Modularnost in prožnost - zmožnost integracije IP video nadzora z drugimi sistemi, kot so nadzor dostopa, alarmni sistem, upravljanje zgradb, upravljanje prometa

IP kamere - funkcije in tehnologije

Resolucija video materialov, ki izdelujejo IP kamere, je HD (720p) ali Full HD (1080p). To pomeni, da bo kakovost videoposnetkov dobra ali velika (koliko denarja je toliko glasbe).

Seveda IP kamere naredijo posnetke, ki vidijo veliko podrobnosti, pri povečavi pa vidijo stvari, ki so nekoliko krajše, zato je veliko več priložnosti za ogled videa.

Postanite "veliki brat"

IP video nadzor, IP kamere, daljinski upravljalnikNekatere kamere IP imajo hkratno funkcijo prenosa signala, ki uporablja različne vrste video stiskanja. Najbolj učinkovite vrste stiskanja so H.264, MPEG4 in MJPEG . Ta funkcija omogoča številne prednosti in funkcije, kot so, na primer, snemanje na pregled v realnem času stanja na tem področju prek pametnih telefonov in tabličnih računalnikov , samodejno pošiljanje slike na e-pošto in shranjevanje video materiala na pomnilniški kartici.

Skratka, ni pomembno, kje ste, pomembno je, da imate pravo napravo (računalnik, pametni telefon ali tablični računalnik) in dobro internetno povezavo . Kamere skupaj s tehnologijami, ki jih imajo, pa tudi s preostalim sistemom, vam bodo prenašale, kaj se dogaja v vašem objektu, medtem ko niste tam.

Motion capture in prenos dela na IP kamere

Progresivno skeniranje je sposobnost fotografiranja različnih predmetov na poti čim bolj čista in jasna. To nam omogoča, da preberemo število avtomobilskih grafikonov, ki jih je minilo, ugotovili, katera znamka je isti avto, prepoznati osebo, ki je minila na kolesu / kolo itd.

IP kamere lahko "upravljajo" nekatere druge omrežne procese , kot so izhodi alarma. Natančneje, dogodki, ki jih kamera zabeleži, so lahko razlog za pošiljanje slik prek FTP ali e-pošte ali kak drug dogodek, ki bo nekaj alarmiral.

Obstajajo tudi kamere z režo za pomnilniško kartico . Ta funkcija je zelo praktična v nekaterih primerih, ko je treba shraniti video material brez možnosti druge naprave za shranjevanje . To se lahko zgodi v situaciji, ko je teren nedostopen in ko pomnilniška kartica ustreza trenutnim potrebam.

IP kamere, kot vsi ostali, imajo različne funkcije in funkcije, ki jih je treba upoštevati pri nakupovanju. Ali ima fotoaparat IR-diode za nočni način , natančneje, ali je fotoaparat oblikovan za delo v temi.

Nato je IP stopnja odpornosti kamere , ali je fotoaparat vodoodporen in v kolikšni meri in ali je odporen na udarce. Nato razdelite razdelke glede na obliko, material in namen . Več o tem lahko preberete na strani Video nadzornega kamere .
