Camera HikVision IP 4MP antivandal audio in si slot card 256GB DS-2CD2743G2-IZS

Descriere

Tehnologia CMOS

Utilizata si in senzorii de imagine al camerelor Hikvision, tehnologia CMOS ajuta la captarea imaginilor la o calitate superioara. Printre caracteristicile importante ale dispozitivelor CMOS sunt imunitatea ridicata la zgomot si consum redus de energie.

Un nou standard este necesar pentru a micsora dimensiunile fisierelor pe masura ce tehnologia avanseaza. Aici intra in actiune standardul H.265+. Acest standard este conceput sa utilizeze o latime de banda mult mai mica multumita tehnicilor de encoding avansate dar si un model de encoding/decoding mai sofisticat.

Zoom motorizat

Avantajele includ posibilitatea de zoom direct pe camera, imagini mai clare, contrast mai bun chiar si in conditii de iluminare scazuta sau la distante focale lungi. Avand si functia de autofocus nu mai este nevoie de o ajustare manuala la fiecare schimbare de cadru.

Modalitatea foarte usoara de configurare a echipamentului permite vizualizarea chiar si de la distanta a camerelor. Aplicatia Hik-Connect va pune la dispozitie, printr-o simpla scanare a codului QR posibilitatea de a monitoriza zona dorita, oricand si oriunde

Monitorizarea de la distanta

Ofera posibilitatea de a urmari locuita personala sau spatiul comercial de la distanta, prin intermediul unui smartphone, tableta sau laptop.   Aceasta e o solutie optima, pentru a vedea transmisia sistemului video de supraveghere detinut intr-o anumita locatie cu ajutorul unei conexiuni la internet, 3G sau 4G.

SD card

Scapa de grija instalatiilor complexe , de amalgamul de cabluri si echipamente grele si costisitoare, deoarece acum poti inregistra si stoca  imaginile pe propriul card SD pe care il conectezi direct la camera.

Back Light Compensation - BLC

Functia BLC (Compensarea luminii din spate) este folosita adesea la imagini in care o sursa de lumina puternica se afla in spatele subiectului de interes. In acest caz, subiectul ar aparea doar ca un contur negru. BLC permite camerei sa regleze expunerea intregii imagini, pentru a evidentia corect subiectul in prim-plan.

3D DNR

DNR este o functie care reduce zgomotul de imagine , in scopul de a imbunatati calitatea imaginii aparatului.In special , se reduce zgomotul  care este generat in conditii de luminozitate slaba.

3D se refera la trei dimensiuni si incorporate in 3D DNR este un circuit  de reducere a zgomotului digital, capabil de a reducezgomotul de imagine si de a imbunatati esecul amestecat de culori si contactul de culori.

ROI Codec

Caracteristica care ofera posibilitatea de a crea o zona definita ROI (Region of Interes), astfel incat imginea va cuprinde mai multe detalii si o calitate mai buna la acelasi bit rate. Latimea de banda si dimensiunea inregistrarii sunt si ele diminuate, deoarece zonele nedefinite ca ROI vor capta imagini la o calitate mai scazuta.

Motion detection

Detectia de miscare presupune analizarea diferentelor dintre doua imagini. Daca diferenta dintre cele doua imagini comparate trece de o anumita valoare data, este detectata miscarea si se declanseaza alarma setata. Elementul cheie in detectia de miscare este Region of Interest (ROI). ROI denota o zona video sensibila la miscare. O zona de detectie a miscarii este in esenta o retea de 16x16 celule. Acestor celule li se impun niste limite de sensibilitate la miscare, valoare la care este declansata automat alarma.

Privacy Masking

Privacy Masking este o caracteristica regasita la multe camere IP, folosita pentru a proteja intimitatea personala prin ascunderea unor parti a imaginii cu ajutorul unei zone disimulate. 

IP67

Nivelul de protectie asigurat de carcasa camerei impotriva accesului la componentele interne, a corpurilor solide sau a patrunderii apei. IP 67 indica un grad superior de protectie asupra factorilor externi si ofera protectie impotriva efectului de imersie, intre 15 cm si 1 m.

IK10

Caracteristica IK10 este un standard ce arata ca o camera poate suporta o energie de impact de pana la 20J. Toate camerele Speed Dome Smart PTZ de la HIKVISION pot fi echipate cu carcasa IK10.

Wide temperature

Domeniul larg de functionare al camerei, ii permite acesteia sa functioneze intr-un mediu cu temperaturi cuprinse intre -30°C si +60°C si cu umiditate de pana la 95%.
