find IP address when you do not know what segment range it is?

On the PC I use 'Advanced IP Scanner'...great tool. And even better is Fing for iOS or Android smartphones & tablets, as you can find ports used, too.
Both are free!

Hi TonyR, I have downloaded Advanced Ip Scanner but am uncertain how you find IPs that are on a different subnet when you are unaware of the cameras IP subnet range.
Back in the days, I connected these unknown devices to a simple hub, with tcpdump (wireshark) running on my pc. When booting up, network cards get talky and you see packets starting to fly around. If you do this trick on your home LAN, you have to "filter" out packets on the MAC address of your cam. I recovered by this mean an old AXIS of which nobody knew the IP address. Once you see the subnet, it's a matter of having your pc in that range, grab the webconfig and off you go.

This sounds interesting. Could you give me a little more information on how to do this?
You stated in post #1 that the cam defaulted to DHCP when reset; if the cam is placed on the same LAN as the PC running 'Advanced IP Scanner', then the 2 should be be on the same subnet and AIPS will reveal that IP.
You may have to manually tell AIPS what range to scan (like 192.168.1.1 to .254) but that is the range of your router (gateway). To find your gateway IP, get on the PC on the same LAN as the cam, type 'Windows Key + R key', then "CMD" <enter>, "ipconfig" <enter>, and your gateway will be listed as "default gateway"!
MORE info:
1) On page 5 of the user's guide it states:
"Restore: Press and hold the reset button for a few seconds. Note that all settings will be restored to factory default."
2) Your cam is stated to be 'Onvif' compatible. if so, you should also be able to access it with Onvif Device Manager after performing the above "restore" and the cam plugged into the same router as the PC running ODM.

I don't know if Vivotek cameras broadcast anything on Bonjour, but a Bonjour browser works for some cameras if Bonjour hasn't been disabled.
ARP also sometimes works to find cameras (you have to know the MAC address) or even to change their IP addresses (if a setting allowing this is enabled).

Thank you.
I have reset to factory multiple times but it is def not defaulting to DHCP as I have used multiple IP scanners and have come up empty-handed. I haven't found a concrete answer on its default values as far as IP settings. Looks like there is limited info due to these being sold by qualified dealers only.
Hmm interesting, I will give Bonjour browser a shot tomorrow as I left the camera at work.

Bonjour is a protocol. There are a number of apps that can browse/list devices that are discoverable with Bonjour. I wasn't referencing a specific app.

If you have the cam's MAC address you can find the IP in Windows from a DOS prompt:

How to Use a MAC Address to Find an IP Address
By Lysis
You can find an IP address from a Media Access Control (MAC) address using the ARP command in a CMD window. It's easier than it sounds.
ARP maps the physical MAC address with the IP. The MAC address is a unique, alphanumeric string programmed on a network card that identifies the computer. The IP address is the number assigned to the network card. Using ARP, the user can find an IP address from the MAC or vice versa.
Step 1
Click the Start button and select Run. In the textbox, type "cmd" and press Enter. This opens a DOS prompt in a CMD window.
Step 2
Type "arp -a" in the command prompt and press Enter. This lists a number of MAC addresses with the associated IP addresses.
Step 3
Since you have the MAC address, scroll down the list to find the associated IP address. The MAC address is shown in the "Physical Address" column with the IP address in the "Internet Address" column.

And, since this camera appears to NOT be a POE device, to you have it powered up with a known-good 12V power supply?

Add to this, make sure that the adapter is 12V DC. I have dozens of adapters and luckily only one is 12V DC I keep that one aside for testing cameras.
