Event based, hybrid and 24/7 CCTV monitoring are three different ways to structure offsite surveillance. The right choice depends on when your site is active, how much movement is normal and how much continuous oversight the risk profile requires.
Choosing the correct monitoring model is more important than simply choosing the longest monitoring period. A busy operational site may need a different approach from a closed warehouse after hours.
What is event based CCTV monitoring?
Event based CCTV monitoring uses analytics to create alerts when predefined activity occurs. Instead of an operator continuously watching every camera, the system directs attention to events such as perimeter intrusion, after hours movement, line crossing, loitering or restricted zone activity.
The operator verifies the alert and follows the site’s escalation procedure if action is required.
When event based monitoring works best
Event based monitoring is well suited to sites where risk is concentrated around defined zones or periods and where normal activity can be clearly separated from suspicious activity.
Examples may include closed premises after hours, perimeter lines, gates, stock areas and selected restricted zones.
What is hybrid CCTV monitoring?
Hybrid monitoring combines event driven alerts with broader operator oversight or scheduled virtual patrols. It is useful when a site has more complex activity and cannot be managed effectively through simple event rules alone.
A hybrid model can allow AI to filter routine movement while operators also perform planned visual checks on critical areas.
When hybrid monitoring makes sense
Hybrid monitoring is often appropriate for sites that remain partly active outside normal hours, have deliveries or staff movements that vary, or need additional human oversight around higher risk zones.
It can provide a balance between focused event handling and more active visual supervision.
What is 24/7 CCTV monitoring?
24/7 CCTV monitoring provides continuous coverage across the full day rather than limiting the service to selected periods. AI analytics can still be used to prioritise alerts, but the monitoring operation is structured for round the clock oversight.
This can be appropriate for high risk sites, continuously operating facilities or locations where incidents can occur at any time and the business requires ongoing monitoring support.
How to choose the right model
Start with the site’s operating pattern and risk profile. Ask:
- When is the site occupied?
- Which zones are highest risk?
- How predictable is normal movement?
- How many alerts are expected?
- Are there overnight deliveries or shifts?
- Does management need scheduled virtual patrols?
- What response procedure follows a verified alert?
The answers should determine the monitoring model rather than selecting a package based only on camera count.
What happens when an event is detected?
Regardless of the coverage model, security outcomes depend on verification and escalation. AI identifies an event, a trained operator checks the footage and the agreed site procedure is followed.

Can the monitoring model change as the site changes?
Yes. Monitoring should be reviewed when operating hours, camera coverage, staffing or risk changes. A site may start with event based monitoring and later move to a hybrid model, or specific high risk areas may receive broader coverage without changing every camera.
Do you need new cameras?
Not necessarily. Compatible existing CCTV can often be integrated into an intelligent monitoring platform. If the physical camera network needs upgrading, our CCTV systems service covers camera design and AI CCTV installation. For the monitoring layer itself, see AI surveillance and offsite monitoring.
Compare service level, not only price
When evaluating monitoring options, compare operator verification, escalation procedures, incident reporting, camera health checks, support and the ability to tune alerts. A cheaper service that creates excessive false alarms or unclear escalation may deliver less value than a properly designed model.
Match monitoring to the site
There is no single best monitoring model for every business. Event based monitoring is efficient for clearly defined risk events, hybrid monitoring adds wider human oversight, and 24/7 monitoring suits sites that require continuous coverage.
