I have the same model and also have had mine for over 2 years and this morning at 10:30am the motion recordings just stopped - I unplugged the base station and plugged back in now it won't sync or connect to my cameras even though my wifi is working perfectly -

What is the status of the LED(s) in the base station (on/off/color, as well as blinking/solid)?

If all the cameras are offline, then restarting the base station is the first step.  You can power-cycle it as @Irishlioness suggests.

If only some cameras are off-line, then you might still try restarting the base (either power-cycle, or using the restart control in the app/web client).  If that fails, you can try removing/reinserting the camera batteries next.
