Yes you can put HTTPListener via ISAPI PUT method. Anything you can do on web can be done via ISAPI, and sometimes even more than whats on web.
For example videointercom door station dot have HTTPListener on web interface, but i have put it this way and it works
See i work for ND and know what your are talking about, as i am also a developer of our integrations and softwares we sell along with Hikvision portfolio. There might be some ND's that only sell without any support.
1 thing you can try
Add http listener data via PUT on
/ISAPI/Event/notification/httpHosts
Body
<?xml version="1.0" encoding="UTF-8" ?>
<HttpHostNotificationList version="2.0" xmlns="http://www.isapi.org/ver20/XMLSchema">
<HttpHostNotification>
<id>1</id>...
I can only from series 7 :/ doesnt necesarily needs to be same as from this camera
i have few of your model on stock, maybe ill plug in 1 next week and give it a go.
Hence why i always go with series 7, it has everything. I always had troubles with this series. But nevertheless it has to have listener option.
If you are using .net, rather use HTTPContext instead of HTTPListener. As you can have multiple services on same port.
