Nothing! Of course we engineer our units be as reliable as possible, but the world is an unpredictable place and unfortunately lighting storms, power surges, and random component failures do happen!
Because Watchmark is hardware-as-a-service, if a unit ever fails simply reach out to support and we'll ship you a replacement unit free of charge!
For enterprise users with many installations or critical downtime requirements, we also recommend purchasing a spare unit and keeping it on hand - that way if a unit fails you can replace it yourself in minutes.
