IR svijetlo. Ovisno od kamere do kamere može biti od 20 do 120 metara ili više metara (EXIR tehnologija)
LED
LED svijetlo je vidljivo svijetlo koje koriste kamere s nocnim radom u boji. Ovisno od kamere do kamere može biti od 20 ili više metara
IP66, IP67
zaštita od vlage i vode. Oznaka da je kamera 100% otporna
IK10
zaštita od udaraca – antivandal kamera
HCL
je značajka koja je nastala zbog prekomjerne ekspozicije od jakih izvora svjetlosti poput svjetala ili reflektora. HLC je vrlo korisno u sprečavanju zasljepljivanja sigurnosnih kamera noću. Čitljivost registarske pločice na parkiralištu na ulaznim točkama.
Frame rate fp/s
broj snimljenih slika u sekundi
Auto Iris
Mehanička funkcija objektiva, koja automatski regulira protok svjetla na senzor kamere.
AWB
Auto Whitte balans je elektronski proces u video kamerama a koristi se da se dobiju realne boje na temelju bijele boje. Proces se odvija na bazi bijelog objekta u slici.
IP kamere
To su Internet protokol kamere namjenjene za rad putem LAN mreze ili UTP kabla.
TURBO HD ili HDTVI, HDCVI, AHD
Nudi video snimak visoke kvalitete putem koaksialnog kabela, idealan za stara ozičenja.
BLC
kompenzacija pozadinskog osvjetljenja
PoE
Power Over Ethernet – napajanje kamera putem UTP kabela, napajanje direktno iz PoE snimaca ili PoE switch-a.
Auto Iris
Mehanička funkcija objektiva, koja automatski regulira protok svjetla na senzor kamere.
CCTV
Close Circuit TV ( Slobodan prijevod Interna TV ) U Hrvatskoj koristimo naziv Video nadzor.
H.264
H.264 je standard za video kompresiju te je ekvivalent za MPEG-4 Part 10, ili MPEG-4 AVC (za Advanced Video Coding ).
Lux
Jedinica mjere za nivo svjetla definirana kada svjetlosni tok od 1 lumena padne na područje od 1 m2.
Min. Illumination
Minimalno osvjetljenje (osjetljivost kamere ) potrebno za rad kamere Osjetljivost kamere povezana je sa F-STOP objektiva , refleksije sa objekta i topline boje. Što je veći F-STOP to je potrebno više svjetla i obratno. Napr: za istu kameru ako je 1Lux / F2,0 onda je 0,5 Lux / F1,4.
Progressive scan
Progresivno skeniranje - način izrade slike tako da se skeniraju sve linije po redu. Bolja slika.
Real Time
Prikaz slike u stvarnom vremenu daje se obično kod DVR-ova, Multiplexera itd.
Resolution
Broj Horizontalnih TV linija za analogne uređaje ili broj točaka (pixela ) za digitalne uređaje.
Rezolucija snimanja
Određuje koliko maksimalno kvalitetno uređaj za snimanje može snimati neki video signal. Rezolucija prikazivanja slike odnosi se na cijeli ekran bez obzira na broj video ulaza ( kamera ). Rezolucija snimljenog materijala ovisi u kojoj je rezoluciji snimam svaki kanal.
Objektiv
Optička komponenta koja se sastoji od jednog ili više elementa optičkog stakla - specijalno brušenih leća.
PinHole Lens
