Monitoring Device Features and Protocol Comparison Table

Standalone monitoring products include the STE2-R2, Poseidon2, Damocles, Ares and WLD units. These devices can send emails, and connect via SNMP to a network monitoring system. They can also be connected to the HWg-Cloud or SensDesk cloud-base portals.IoT monitoring devices include the NB (NarroBand) series must be connected one of the two portals.
