remote

Hi all, Some time ago, I was able to let my Hikvision IP camera make some additional sounds to remote location like siren, dog barking etc. from internet explorer, there was a special button dedicated to this feature. Now I can't find it in any other browser or application. Can anyone tell me...

Hi Is it possible to connect a remote DVR system with cameras to my local Hikvision DVR so I can monitor both sets of cameras on the one system? Many thanks
