CCTV Health Monitoring & Vision AI · Built in the UK

Know about the fault
before your client does.

Surveillance Guardian checks the complete CCTV system every 5 minutes — cameras, recorder, drives, firmware, even the system clock. Our in-house Vision AI then scores every camera's evidence quality out of 100, day and night, so you know the footage will actually stand up when it matters. Remote access to any system with zero port forwarding, footage retrieval and GDPR redaction from your desk, and instant connection to any UK ARC.

Issues identified
before clients are aware.

Surveillance Guardian continuously monitors every camera, recorder and drive on every site. Problems are flagged early — giving you time to schedule, quote, and fix them on your terms.

📡
5-Minute Health Checks
Every camera and recorder polled continuously. Status checks every few minutes — not manually, not quarterly.
💾
Drive & Storage Health, Checked Daily
Capacity, drive status and errors monitored daily. Replace drives on schedule — not when footage is lost during an investigation.
🕐
Firmware & Clock Verification
Outdated firmware flagged for update, and the system clock checked against real time — because footage with the wrong timestamp is worthless as evidence.
⚙️
Auto Job Creation
Critical faults generate a job in the EM8 Portal, assign it to an available engineer, and trigger notifications to EM8 HQ.

A working camera isn't
a useful camera.

A camera can be online, recording, and completely useless — out of focus, blinded by glare, knocked out of position, or too dark to identify anyone. Traditional monitoring can't see that. Vision AI can.

🎯
Evidence Quality Scored Out of 100
Every camera analysed automatically and given an evidence quality score — with a severity rating and confidence level, so you can prioritise real problems.
🌗
Scored Separately Day and Night
A camera that looks perfect at noon can be blind at midnight. Vision AI scores both conditions independently, so IR failures and night-time exposure problems don't hide.
🔍
Blur, Glare, Darkness, Noise & Occlusion
Individual health checks pinpoint exactly what's degrading the image — so the engineer arrives knowing whether it's a focus issue, a dirty dome, or a blocked view.
🛡️
Tamper & Scene-Change Detection
If a camera is moved, covered, or repositioned, Vision AI notices the scene has changed and flags it — even when the camera itself reports no fault.
🧠
Scene Understanding
Each view is described in plain English — people, vehicles, environment — building a verified record of what every camera actually covers.

Everything a site needs,
in one place.

This isn't a status light and an email alert. Every monitored site gets a full management console in the EM8 Portal.

Cameras

Live camera health

Every camera at a glance — healthy, faulted, or outdated — with its Vision AI evidence score, severity and last-checked time front and centre.

System

Recorder deep-dive

Model, firmware (with update-required flags), clock accuracy, enabled protocols and ports, recorder users, and per-camera detection settings — motion, human, vehicle, line crossing and more.

Storage

Drive health & capacity

Every drive checked daily for errors and capacity. Failing storage is flagged before recordings are lost, not after.

Vault

Every report, archived

Daily fault reports and per-camera fault reports generated as PDFs automatically — searchable, previewable, and emailed straight to the client as proof of service.

Gatekeeper

Recorder credential control

Rotate recorder passwords per user, reveal them securely on demand, disable accounts instantly — with every single password request logged.

Footage

Retrieve from your desk

Pick a camera, pick a time window, and pull the footage remotely. Play it in the browser, download it, or email it — no site visit, no USB stick.

Redaction

GDPR redaction, one click

Faces blurred automatically before footage is released. Subject access requests handled in minutes instead of days.

Logs

A complete audit trail

Device changes, footage requests, redaction jobs and password reveals — all recorded with who, what and when. Your GDPR accountability evidence, written for you.

Remote GUI & ARC

Full remote control

Access the recorder's native interface securely from anywhere, and connect the site to any UK ARC through Cortex Connect — no port forwarding either way.

Who knows your
recorder passwords?

Be honest — it's the same admin password on half your estate, known by every engineer who's ever worked for you, including the ones who left. Gatekeeper ends that.

🔄
Rotate Passwords Remotely
Change any recorder user's password from the portal in seconds — per user, per site. Engineer leaves? Rotate everything they touched before they're out the door.
👁️
Reveal on Demand, Never Stored in the Open
Passwords aren't sat in a spreadsheet or a WhatsApp group. They're fetched securely when needed — and every reveal is logged against the person who requested it.
🎭
Role-Based Recorder Access
Admin, operator, viewer and restricted engineer accounts managed per site — so subcontractors get exactly the access they need and nothing more.
📜
Every Request Logged
A permanent record of who requested which credential and when. When a client or auditor asks who had access to their CCTV, you have the answer in seconds.

Incident footage
without the site visit.

"Can you get us the footage from Tuesday afternoon?" used to mean a van, a USB stick, and half a day. Now it's a date picker and two minutes.

📅
Pull Any Window, From Any Camera
Select the camera and the time range, and the hub retrieves the recording segments directly from the recorder — over the secure tunnel, from any site.
▶️
Play, Download, or Email
Review clips in the browser before deciding what to release. Download for evidence packs, or email straight to the client or the police from the portal.
🎭
One-Click GDPR Redaction
Faces of uninvolved people blurred automatically before footage leaves the platform — with an AI quality check on every redaction. Subject access requests stop being a liability.
📜
Everything on the Record
Every footage request, retrieval, redaction and release is logged with the requester, the camera and the exact window. That's your ICO accountability trail, built in.

Stop finding out about problems
the hard way.

The difference between losing a contract and renewing it often comes down to who picks up the phone first.

Without Surveillance Guardian
  • Clients call you when cameras go offline — you're always on the back foot.
  • Cameras "working" but out of focus, glared out, or blind at night — nobody notices until footage is needed.
  • HDD failures only discovered when footage is urgently needed.
  • Footage requests mean a site visit, a USB stick and a wasted afternoon.
  • The same admin password on every recorder, known by everyone who's ever worked for you.
  • Port forwarding on every site — a growing attack surface.
With Surveillance Guardian
  • You call the client before they even notice a fault.
  • Vision AI scores every camera's evidence quality — day and night — and flags degradation the moment it starts.
  • Drive health checked daily. HDD degradation flagged weeks in advance.
  • Footage retrieved, redacted and emailed from your desk in minutes.
  • Gatekeeper rotates credentials per user, per site — every reveal logged.
  • Zero inbound ports. Zero exposed IPs. Zero attack surface.

Built for serious
CCTV engineers.

UK-Built AI Platform

Cortex AI runs on our own UK infrastructure. No US cloud, no data leaving the country, no surprises.

Zero exposed ports.
Zero attack surface.

Traditional remote CCTV access means port forwarding — punching a hole in your client's firewall and exposing recorders directly to the internet. Surveillance Guardian uses outbound-only tunnels through our own UK infrastructure. No open ports. No static IPs. No targets for attackers.

Works on any internet connection. No broadband? Use our 4G option — a dual-antenna variant ships with a UK SIM and runs anywhere with mobile coverage.

Every fault found is
a billable service call.

Surveillance Guardian doesn't just save you time — it turns your maintenance contracts into a proactive revenue stream.

New service revenue

Every flagged fault is a justifiable callout. Degraded drives, failing cameras and low evidence scores become planned, billable work.

−⏱

Fewer emergency site visits

Reboots, footage retrieval, config changes and diagnostics handled remotely. Only dispatch an engineer when hands are actually needed on site.

Higher contract retention

Clients who feel looked after don't shop around. Proactive calls and daily fault reports justify your maintenance pricing.

Connect to any UK ARC in seconds.

Cortex Connect is our secure tunnel infrastructure for Alarm Receiving Centres. No port forwarding, no VPN setup, no firewall requests — just instant, encrypted, auditable connections between your sites and the ARC.

Common questions
from installers.

QWill Surveillance Guardian work with my existing CCTV systems?
Yes. It's designed to sit alongside any DVR or NVR — Hikvision, Dahua, Axis, Hanwha and every other major brand. You don't rip and replace; the hub plugs into the network and discovers the system.
QWhat exactly does Vision AI check?
Every camera's image is analysed for blur, darkness, glare, noise and occlusion, then given an evidence quality score out of 100 — separately for day and night conditions. It also detects tampering and scene changes (a camera that's been moved or covered), and describes what each camera actually sees. All of it runs on our own UK infrastructure, built in-house.
QWhat is Gatekeeper?
Gatekeeper is credential management for the recorders themselves. Rotate any recorder user's password from the portal, reveal a password securely when an engineer needs it, and disable accounts instantly — with every request logged against a named person. No more shared admin passwords across your whole estate.
QDoes it need port forwarding or a static IP?
No. Every connection is outbound-only through our UK infrastructure. There are no open ports on the client's network, which removes a significant attack vector entirely.
QWhat if the site doesn't have a reliable internet connection?
Our 4G variant ships with dual antennas and a UK SIM. It works on any site with mobile coverage, and can act as a primary or failover connection.
QHow is footage retrieved and redacted for GDPR?
Pick a camera and a time window in the portal, and the hub pulls the recording remotely — play it in the browser, download it, or email it. Automatic face redaction is applied before footage is released, and every request, retrieval and export is logged with who, what and when: a ready-made accountability trail for subject access requests and ICO audits.
QHow quickly can I get started?
Most installers are up and running on their first site within the afternoon. Plug in the hub, onboard the site in the EM8 Portal, and you're monitoring.
