StoNe- Posted June 17, 2013 Report Posted June 17, 2013 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.

jojo123 Posted June 17, 2013 Report Posted June 17, 2013 (edited) 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. Edited June 18, 2013 by jojo123 Quote
StoNe- Posted June 17, 2013 Author Report Posted June 17, 2013 Aha, multumesc de raspuns. Si pe baza caror date se poate vizualiza asta prin clientul lor? Quote

StoNe- Posted June 18, 2013 Author Report Posted June 18, 2013 Care este portul default? Vreau sa verific un PC daca trimite imaginile luate de camera. Quote
jojo123 Posted June 18, 2013 Report Posted June 18, 2013 SmartDVR default (daca cel care a instalat nu a schimbat) 26540 sau 20408VIDI default ---3000 3003 3007 3001Ambele "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) 1 Quote
StoNe- Posted June 18, 2013 Author Report Posted June 18, 2013 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. Quote

2time Posted June 18, 2013 Report Posted June 18, 2013 vezi ca ai setari de user la dvr sa fie o singura conexiune pe user , daca esti conectat nu se mai concteaza nimeni pe useru respectiv .. Quote
