Zero-Trust Network Architecture

Built for Enterprise Security & Zero IT Friction

Traditional cloud surveillance forces network engineers to punch holes through corporate firewalls, configure dynamic DNS, or buy costly static public IPs. Camtil eliminates these vulnerabilities completely.

NETWORK 01

Zero Inbound Open Ports

The Edge Appliance initiates all connections outward through encrypted web tunnels. Your corporate firewall remains completely closed to inbound scanners, hackers, and external threats.

No router port forwarding
Immune to Shodan & port scanning
Bank-grade transport encryption

NETWORK 02

Firewall & CGNAT Traversal

Seamlessly traverses strict corporate firewalls, corporate proxy servers, and carrier-grade NAT (CGNAT) on commercial fiber and 4G/5G industrial cellular connections without a static public IP.

Works on dynamic IP broadband
Eliminates monthly static IP leases
Deep Packet Inspection (DPI) friendly

NETWORK 03

Multi-Subnet Discovery

In real-world facilities, cameras are often scattered across multiple legacy VLANs and IP subnets. Camtil automatically discovers and binds secondary IP aliases to bridge all cameras on a single physical link.

Zero router re-addressing
Connects across isolated camera VLANs
Plug directly into any PoE switch

Reliability Engineering

Autonomous Self-Healing Watchdogs

Deploy the Edge Appliance and forget it. Internal automated watchdog services constantly monitor network health, cycle interfaces during dropouts, protect flash storage from log exhaustion, and broadcast a local Wi-Fi maintenance hotspot for easy smartphone configuration.

Network Watchdog: Automatically restarts connections during ISP drops.
Log Guard: Prevents storage exhaustion and extends appliance lifespan.
Lens AI Edge Engine: Runs local ARM-accelerated 8-parameter optical and stream integrity audits (Blur, Glare, Obstruction, Tamper, Frozen Stream, Darkness, IR-Cut, Signal Loss).
Universal Compatibility: Works with all standard ONVIF, RTSP, and OEM IP camera brands.

Hardware & Architecture

Edge Appliance Technical Specifications

Commercial off-the-shelf economics ($100 COTS) replacing $2,500 proprietary black-box bridges.

Processor & Compute	Quad-Core ARM Cortex-A76 @ 2.4 GHz with ARM NEON SIMD vector acceleration. Runs all 8 optical AI checks in <10 ms per frame.
Memory & Efficiency	4GB / 8GB LPDDR4X. Flat memory footprint of ∼35 MB (<0.5% RAM) and <1% total CPU utilization for 100 cameras.
Zero-Trust Stealth Tunnel	Encrypted outbound zero-trust tunnel over standard HTTPS (Port 443). Requires zero inbound open ports, completely eliminating firewall vulnerabilities while effortlessly penetrating CGNAT and enterprise DPI firewalls.
Subnet Auto-Discovery	Intelligent multi-subnet bridging automatically discovers and binds to cameras distributed across isolated VLANs and legacy subnets without requiring router re-addressing or network topology changes.
Self-Healing Watchdogs	Autonomous background watchdogs deliver self-healing connection restarts during ISP drops, multi-protocol time synchronization when NTP is restricted, and proactive flash memory protection for long-term unattended reliability.
Zero-Monitor Mobile Setup	Built-in maintenance wireless provisioning allows on-site technicians to pair, configure, and verify all camera streams in under 5 minutes directly from any smartphone without needing a physical monitor or laptop.
