Camera de supraveghere IP Bullet 2MP Hikvision Darkfighter DS-2CD7A26G0/P-IZHS cu zoom motorizat

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.

 Functia Ultra LowLight ofera imagini lare si pline de culoare chiar si pe timp de noapte.

Scanare progresiva

Scanarea progresiva este o tehnologie asociata camerelor cu senzor IP si este utilizata la transmiterea, afisarea sau stocarea imaginilor in miscare.

In mod traditional , metoda de scanare utilizata in majoritatea  formatelor de semnal video a fost intreteserea, utilizata la dispositive cum ar fi , camerele CCTV analogice.

Mod de functionare!

Toate liniile vertical ale imaginii sunt afisate in totalitate pe fiecare cadru in loc sa fie impartite in campuri separate.

Principalul avantaj al acestuia consta in claritatea imaginii, in special atunci cand un subiect este in miscare.Cu ajutorul unui senzor progresiv imagistica de scanare reduce efectul de rupere si miscare estompata.

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.

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.

Wide Dynamic Range – WDR

Este o tehnologie utilizata de camerele de supraveghere video CCTV, cu scopul de a echilibra imaginile video care au o gama dinamica mare. Aceasta este o caracteristica care confera camerei, posibilitatea, de a aplica intensitati separate ale luminii pentru aceeasi imagine. Aceasta functie este ideala pentru imagini care cuprind atat zone luminate cat si zone intunecate.

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.

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.

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.

Line crossing

Aceasta functie poate detecta obiecte, persoane sau masini ce depasesc o linie virtuala predefinita. Reprezinta o solutie ideala pentru monitorizarea intrarilor, a parcarilor sau alte zone delimitate.

Intrusion detection

In cazul de detectare a intruziunilor, camera video porneste simultan alarma si inregistrarea de evenimente. Prin aplicarea celor mai recenti algoritmi, analizeaza in mod automat dimensiunile intrusului pentru a minimiza si estompa alarmele false. Aceste caracteristici sunt foarte folositoare pentru siguranta zonelor predefinite.

Face detection

Prin aplicarea tehnologiei de detectare a fetei, camerele IP de securitate, pot detecta precis trasaturile faciale umane, le pot analiza si declansa alarma in cazul in care este setata una.

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.

IP

O camera IP este o camera video digitala in retea, care transmite datele printr-o legatura fast ethernet link. Camerele IP (deasemenea numite “camere de retea “) sunt cel mai des folosite pentru supravegherea video, o versiune digitala si de retea a televiziunii cu circuit inchis (CCTV).Beneficiile camerei IP fata de tehnologia analogical :- Administrare de la distanta din orice locatie;- Zoom digital;- Capacitate de a trimite cu usurinta imagini si video oriunde , cu o conexiune la internet;- Scanare progresiva, care permite imagini de o calitate mai buna extrase din inregistrare, in special pentru tintele mobile;- Numarul de cadre reglabil pentru a atinge specificatiile cerute;- Capacitatea de a trimite semnale de alerta in cazul in care este detectata activitate suspecta;- Cerinte de cablare mai mici.

Datorita standardului ONVIF incorporat, camera poate fi asociata si cu NVR-urile altor producatori.

Power over Ethernet – PoE

Reprezinta modalitatea de alimentare a camerelor sau a altor echipamente IP, prin intermediul cablului de retea. Implementarea retelei se rezuma la un singur cablu, prin care este transmis semnalul de date cat si alimentarea echipamentului. Prin intermediul PoE, instalarea sistemelor de supraveghere devine mult mai simpla, mai sigura si mai putin costisitoare.

Cum functioneaza DDNS?

Daca doriti sa accesati o camera CCTV sau un server de gazduire dar adresele IP atribuite lor nu sunt statice, atunci serviciul DDNS este solutia.

Majoritatea providerilor de internet nu oferta IP static, dar pentru accesarea echipamentelor de monitorizare video fara a inlocui de fiecare data adresa IP se va configura serviciul DDNS. Similar cu un server DNS, acesta creaza o baza de date care contine relatiile dintre domenii si adresele numerice, actualizarea facandu-se la intervale de timp prestabilite sau automat la schimbarea adresei IP. Datorita acestei facilitati, DVR-ul/NVR-ul sau camerele tale vor fi disponibile la domeniu cunoscut, indiferent de IP-ul acestuia.

IP 67

Un numar IP este utilizat pentru a specifica protectia mediului in incintele din jurul echipamentelor electronice.Aceste evaluari sunt determinate  prin teste specific.

Numarul IP este compus din doua cifre, prima referindu-se la protectia impotriva obiectelor solide si a doua impotriva lichidelor.Cu cat numarul este mai mare cu atat protectia este mai crescuta.

Prima cifra 6 :

Protectia pentru persoane: protectia impotriva atingerii unei parti periculoase

Protectie pentru echipamente : protective impotriva prafului.

A doua cifra 7 :

Protectie impotriva efectului de imersiune intre 15 cm si 1m.

Wide temperature

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