3. Architectural Highlights 3.1 Imaging Pipeline SSIS-878 4K

Sensor → ISP – The stacked sensor integrates a dedicated Image Signal Processor (ISP) that performs real‑time demosaicing, noise reduction, and HDR tone‑mapping. AI Accelerator – A dedicated NPU (Neural Processing Unit) provides up to 10 TOPS for edge inference, allowing analytics to run without external servers. Encoder – Dual H.265/HEVC hardware encoders support simultaneous 4K 30 fps and 1080p 60 fps streams, with configurable bitrate (2 Mbps – 30 Mbps). Network Stack – Multi‑queue Linux kernel (3.19) with DPDK off‑load ensures low‑latency packet handling; QoS prioritization for alarm streams.

3.2 Power Management

PoE++ supplies both power and data over a single cable, simplifying installation. Dynamic Power Scaling reduces consumption to <10 W in idle mode; active streaming at 4K 30 fps draws ~35 W. Architectural Highlights 3

3.3 Security Hardening

TLS 1.3 encrypted RTSP/HTTPS. Secure boot and TPM 2.0 for device integrity. Role‑based access control (RBAC) integrated with LDAP/Active Directory.
