Hey NhaTrang, I'm trying to do the same thing. Swann NVR died and replaced the NVR with HikVision. Regarding the IP address of the Swann IP camera, a few things I found today:
1. My Swann camera model is SRNHD-815CAM.
2. I plugged the Swann camera directly into the HikVision NVR to power it up together with plugging my laptop into the same 8 x PoE ports on the Hik-NVR. Going into Hik-NVR Camera settings, I see that the Hik-NVR is showing "Detecting: message on the screen.
3. Pre-download a Windows IP tool call "Network Pinger" and extract it to my laptop.
4. Assign my laptop a static IP address of 172.16.1.2, 255.255.255.0 and do a Ping Sweep (range 172.16.1.1 to 172.16.1.254) - using Network Pinger tool >> This step did not help because no devices replies.
5. Reassign my laptop a new static IP address of 192.168.1.1, 255.255.255.0 and do a Ping Sweep (range 192.168.1.1 to 192.168.1.254) - using Network Pinger tool >> This step helped because device 192.168.1.65 replies. Just to make sure that I'm doing the right thing ....
6. Keep same static IP as step 5, reboot the swann camera and the same ping sweep now return device 192.168.1.191 replies.
7. Tried
http://192.168.1.191 and
https://192.168.1.191 but none works.
8 Use Network Pinger to scan opened ports on IP 192.168.1.191 and this is what I found:
Ports opened on the camera as detected by Network Pinger:
PORT STATE TIME SERVICE
80/tcp open 13ms Hypertext Transfer Protocol (HTTP) (TCP/UDP - Official)
443/tcp open 24ms HTTPS (Hypertext Transfer Protocol over SSL/TLS) (TCP - Official)
554/tcp open 14ms Real Time Streaming Protocol (RTSP) (TCP/UDP - Official)
6001/tcp open 7ms There is no available information about this port on the database...
8000/tcp open 9ms iRDMI (Intel Remote Desktop Management Interface)[40]—sometimes
erroneously used instead of port 8080 (TCP/UDP - Official)
8000/tcp open 9ms Commonly used for internet radio streams such as those using SHOUTcast
(TCP - Unofficial)
9000/tcp open 17ms Buffalo LinkSystem Web access (TCP - Unofficial)
9000/tcp open 17ms DBGp (TCP - Unofficial)
9000/tcp open 17ms SqueezeCenter web server & streaming (TCP - Unofficial)
9000/tcp open 17ms UDPCast (UDP - Unofficial)
At this stage I don't really know how to proceed further. From what I can see, port 80 and 443 are opened on the camera but I cant seem to be able to connect to the swann camera. There are other threads on this forum with users able to get into the camera but using their method on my camera (http and https) doesn't seem to work.
Let me know if you are able to add the swann cameras into the HikVision unit.
