What is the difference between a SSiQ, INVR, and DVR?

A DVR (Digital Video Recorder) and INVR (Internal Network Video Recorder) are traditional recording devices that capture and store video footage locally. A SSiQ (Server Switch iQ), which CSG uses as the standard, combines a high-performance video server with a built-in network switch in a single hardened unit — reducing cabling complexity and including cybersecurity hardening features that standard INVRs and DVRs lack.

DVRs are the oldest of the three — analog-based recording devices that connect directly to cameras via coaxial cable. They are simple but lack the resolution, flexibility, and network integration of modern IP-based systems. INVRs are the network-based successor to DVRs, connecting to IP cameras and storing footage digitally — but they remain standalone recording appliances without the additional capabilities of a purpose-built platform.

The SSiQ represents a meaningful architectural advancement. By combining the video server and network switch into a single hardened unit, it reduces the number of components, simplifies cabling, and removes a potential failure point. The cybersecurity hardening built into the SSiQ — including encrypted storage and outbound-only communication when paired with Piko — addresses vulnerabilities that standard INVRs and DVRs leave exposed. For financial institutions where cybersecurity posture is subject to regulatory review, the SSiQ's hardened architecture provides a stronger compliance foundation.
