Internet Web based monitors and alarms allow users to monitor, get alerts and log sensor data with no land line telephone required. These alarms and data loggers either use a built in web server and on board storage, or a cloud based structure to protect your property. Temperature and power alarms with data logging allow critical facilities to be protected including data-centers, cold storage, medical refrigeration units and more. Alarms can be set to call one or more users if any of the sensors go outside their normal range or if power fails. Plus the data may be logged for internal review or to show to government agencies.
