thanks, looks like I really need to update the firmware to all of my cameras. Can you tell if this model is also belongs to G1 category?

EDIT
This is relatively old model
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...
