Why choose Deep Sentinel

Operator and ecosystem context

Plan structure and pricing tiers

The tier ladder splits across Surveillance Service for testing the service, Surveillance + Cellular Backup for everyday use, and a premium / annual option for power users or teams. Anchor pricing for 2026: USD 60/month per system (3 cameras); add USD 20/month per additional camera (2025). Consult Subger's true-price tracker for Deep Sentinel for all-in renewal costs.
