Honestly it really depends what you are mostly doing with the keyboard. If you are planning on writing a lot, people usually lean toward tactile switches. It has a little bump on the click which feels quite nice. Strict gaming usually go linear since its faster to trigger. Then there is the weight. Lighter weight for faster pushing, higher weight for really knowing you are pushing the key.

My preference is a medium weight tactile switch, preferably silent. I thought the heavy switched were too much for my taste. Light didn’t have enough resistance.

For OP. Reolink has a DVR and wireless type cameras.

However be careful on which cameras you get as not all the wireless versions work with the DVR. Think this is mostly the battery powered ones. Also not sure if this has changed since original purchase a few years back.

Currently Guild Wars 2, I suppose.
