D-Link 5020L e ZoneMinder. Guida su come configurare ZoneMinder con telecamere D.Link 5020L Nel wiki di ZoneMinder si trovano i riferimenti a tutte le telecamere supportate, comprese queste, ma in questa guida ci saranno immagini per tutti i passaggi. I parametri da inserire quando si aggiunge la telecamera sono i seguenti:

Source Type: Remote
Remote Protocol: HTTP
Remote Method: Simple
Remote Host Name: user:pass@IP-Camera
Remote Host Port: 80 (Default)
Remote Host Path: /video.cgi
Colors: 24 bit
Capture width: 640
Capture Height: 480

PTZ Settings:

esiste uno script nel wiki che serve a far funzionare il tutto:

e va copiato nel PATH: /usr/share/perl5/ZoneMinder/Control. Dopodichè andare nel menu Control-Edit-Add New Control:

ed inserire i parametri  seguenti:

Main: Type: Remote, Protocol: DCS5020L, Name: DCS5020L, Can Wake, Can Sleep, Can Reset
Move: Can Move, Can Move Diagonally, Can Move Mapped, Can Move Relative
Pan: Can Pan, Min Pan Step 1, Max Pan Step 30
Tilt: Can Tilt, Min Tilt Step 1, Max Pan Step 30
Presets: Has Presets, Number: 24, Has Home Preset

Nel Tab Control inserire:

Controllable, Control Type: DCS5020L, Control address: user:pass@ipaddress

D-Link 5020L e ZoneMinder

adesso tutto è pronto per la video sorveglianza.

enjoy 😉
