The Snug baby monitor is a great inexpensive monitor, but it lacks in documentation for a feature that I think is one of its nicest features; namely, it can be monitored on the computer.
The instructions below are specifically for the Snug Baby Monitor, but the instructions should also work for most other baby monitors.
The concept is actually quite simple; type in the IP address and port of the baby monitor. Finding the baby monitor's IP address can be a bit trickier though.
Step 1: Download Nmap (Network Mapper).
(2017-03-07 Update: I found something I prefer over Nmap. It is called Angry IP Scanner. It is Open Source and available for any OS. It is super simple to use. Just make sure that you go to Tools>Preferences>Ports and add the port 81 as a port selection)
I must admit that installing and using Nmap can be a bit daunting, but it is one of the best tools for finding the IP addresses of devices connected to your computer. Nmap is cross platform compatible and can be installed on Windows, Mac, or Linux.
Step 2: Do a scan for all devices on your network. We need to find the IP address of the baby monitor.
To do a scan, you will need to manually enter the range of IP addresses you want Nmap to look for. Typing the following should be sufficient (this will look for devices in the range of 10-90):
Now press the "Scan button." (NOTE: I am doing this in Linux, so the GUI you use might be different from the screenshots you see below.)
After you press the scan button, you will just need to sit tight for 1 - 5 minutes. Nmap is going through each IP address and looking for activity. After it has completed the scan, you will should notice that an IP that shows up with an OS associated with it.
For my setup (screenshot above) I have an OS that is "Undiscovered." What it says here does not necessarily matter as it is doubtful that that the device will be recognized. Write down the IP address. In my case it is 192.168.1.12.
If you get multiple IP addresses with an OS showing up next to it, write down all the addresses; you might have to try a few times.
Step 3: Enter the IP address into your web browser. Add port :81 to the end of the IP address.
Now that I know the IP address of my device, I can enter that into my browser adding port :81 to the end of the IP address
192.168.1.12:81 (This number will almost definitely be different for you)
Note: Different baby monitors might have a different port.
Step 4: Enter the username and password.
The credentials will be whatever you set. If you didn't set a username or password, then the default username is usually admin and the default password is usually left blank.
Lastly, just choose the options presented and you are well on your way to viewing your baby monitor!

Yay for baby monitors!
