Pro Locally stored data
All data is stored locally on an SD card - included is an 8GB card. Even better - the slot is push activated, meaning it will spring out when you push it in again. This is an example of the good attention to small details.
The SD card can only hold so much video though, and once storage space has run out it will overwrite any existing files. This means that if you want to keep any videos, it's important to regularly save them to another storage location (or insert a larger card).
Pro Facial recognition
While not a reliable source of security, the Netamo Welcome can sometimes get faces right. It has trouble differentiating between bearded folks, but other than that it does a decent job once it's sufficiently learned the different faces (it can take up to 2 weeks).
Pro Versatile video
With the wide angle lens (130 degrees), this camera is set to record any action in front of it, as well as slightly to the sides of the main focal point. It also includes a night vision mode, where infra-red LEDs illuminate the darkness but aren't visible to human eyes. This is called night mode, and shows up in greyscale, but in decent enough quality to still be able to see everything that's going on in the frame.
Pro Web app included
While some home security cameras only support mobile apps, this one allows you to view the important information in a web browser for your convenience (configuring the camera itself needs to be done through the app, but it's nice to be able to view the live steam on any computer and not just your phone).
Con Visible light when in night mode
When night mode is enabled, there is a glowing red light. This defeats the purpose of its stealthy design, and feels obtrusive when you are walking around your house in the dark - almost like something is watching you (because you are indeed being watched).
