Trimitere imagini camera de supraveghere

Recommended Posts

Posted

Salut.

Este posibil ca imaginile luate de o camera de supraveghere, sa fie trimise in timp real catre un calculator care nu se afla conectat la ele?

Ceva de genul: camera -> conectat la PC -> pe PC un "virus" ce trimite imaginile catre alt PC.

Multumesc anticipat.

In principiu da. Multe placi de captura( eu am lucrat cu smartdvr si vidi) au si "soft client" cu care poti vizualiza/captura . Problema e ca trebuie sa faci port forward in router.

SmartDVR default (daca cel care a instalat nu a schimbat) 26540 sau 20408

VIDI default ---3000 3003 3007 3001

Ambele "servesc" si pe HTTP (80)

//calculatorul cu placa DVR nu trimite , doar permite conexiuni (de regula cand e cineva conectat il vei vedea in aplicatie sau in log-urile aplicatiei)

Ok, multumesc inca o data de raspunsuri. Sa vad ce iese acum, daca il pot verifica pana la capat, sa dau un raspuns persoanei respective daca este monitorizata de la distanta, sau nu.

Eu as incerca urmatoarele:

-verific setari DVR (si vad daca sunt permise conexiuni de la distanta)

-instalez un firewall ca sa vad ce conexiuni "ilegale" apar

-monitorizez traficul (wireshark)

//cred ca ar merge si o scanare de porturi a hostului respectiv sa vezi ce are deschis
