For a number of years, I have used Crashplan as my offsite backup. I found the price and features attractive. It also worked on Linux which further won me over since I was running a Linux server as my file server. Their unlimited plan for a single machine was very affordable especially when purchasing multiple years. $3-4 per month for unlimited backup was well worth the price to have peace of mind in case something bad happens at home (I actually did need to use it one time when I had a failing hard drive corrupt several of my files).
As I have mentioned in my how-to on creating an isolated network, I have several Amcrest IP cameras (affiliate link) on an isolated network which I use mostly as high quality baby camera monitors. Recently my family decided to get an outdoor camera (affiliate link) to put on the front porch and a video doorbell (affiliate link) for the front door to help monitor the entire front of our house.
When I decided to do a fun project with my old Raspberry Pi 3B+, I purchased the 4GB model of Raspberry Pi 4 to have as a replacement (update: now they have an 8GB model that would be nice to have). Since I am working from home due to COVID-19, my main PC is completely utilized for work during the weekdays via a VPN connection. I thought it would be convenient if I had a second computer at my desk so that I can listen to background music from my Plex Media Server or use it for personal things such as banking, shopping, paying bills, and browsing the web during lunch.
When creating content for this website, I often have the need to take screenshots of the OPNsense web interface. Sometimes I am able to use my actual home network router to take screenshots, but I have to be careful not to modify any settings. I sometimes have to resort to tweaking the screenshot slightly after taking it in order to show what the interface should look like without everything already configured.
I recently bought the Amcrest video doorbell (affiliate link) since I like my other Amcrest IP cameras, and I wanted a doorbell that was less cloud connected (the Amcrest doorbell requires an online account for the initial configuration but can be used completely offline at the expense of losing push notifications to answer the doorbell). The doorbell has the RTSP capability, so the video stream can be recorded based on motion events and/or 24/7 recording with video surveillance software like BlueIris or hardware such as the Amcrest NVRs (affiliate link).
