What is Z-Wave Security 2 (S2)?
Security 2 (S2) is the latest communication protocol and new industry standard for Z-Wave devices. The protocol effectively makes smart devices faster, more secure, and better-performing than ever. For customers, this means fewer issues and peace of mind. For dealer partners, this means reduced support costs and fewer truck rolls.
To pair to a network, an S2 Z-Wave device shares its encrypted Device Specific Key (DSK) with the security panel during Z-Wave enrollment.
Note: S2 devices are compatible with S0 devices and can be added to existing systems with older Z-Wave devices and panels. However, only communication between S2-enabled devices and panels will utilize the S2 protocol and provide the associated benefits.
Benefits
The S2 communication protocol for Z-Wave devices offers the following benefits:
- More reliable communication
- Longer device battery life
- Encrypted security keys
- Unique device pin codes for out of band key exchange
