When we talk about CCTV and security, the focus is usually on perimeter breaches, break-ins, or triggered alarms. But another behaviour is often overlooked — and it can be just as important to monitor: loitering.
We all know that when someone is hanging around where they shouldn’t be — especially for longer than necessary — it usually raises concerns. Whether it’s someone lingering in a car park, a hotel lobby, or near a staff-only entrance, this type of behaviour can be an early warning sign of something more serious. They could be watching the site, waiting for a quiet moment, or posing a risk to staff, guests, or property.
Loitering detection is a smart solution for 24/7 environments where people are expected to pass through, not stay put. It helps identify behaviour that stands out, allowing security teams to act before a situation escalates, making it a valuable layer of protection for busy, public-facing sites.
What Is Loitering Detection?
Loitering detection is an AI-powered video analytics feature that monitors a defined zone and alerts you when a person remains within that area beyond a pre-set amount of time (e.g. 60 seconds, 5 minutes).
The system can then:
- Trigger a notification to a remote monitoring station
- Activate a visual or audible deterrent (e.g. light, speaker)
- Send an email or push notification
- Bookmark the event for investigation
Unlike motion detection — which responds to anything that moves — loitering detection focuses on human behaviour over time, resulting in more accurate and actionable alerts.
Benefits of Loitering Detection
Early Intervention
Spot suspicious behaviour before a crime occurs. Loitering is often a precursor to theft, vandalism, or unauthorised access.
Improved Safety
Alerts for people lingering near hotel entrances, stairwells, or exit doors can prevent security risks and enhance staff and guest safety.
Reduced False Alarms
AI analytics can differentiate between someone walking by and someone deliberately hanging around, reducing unnecessary callouts.
Better Evidence
Incidents are timestamped and often bookmarked in video systems, making it easy to investigate and review footage.
Integration with Remote Monitoring
When integrated with a professional monitoring station like Farsight, loitering events can be assessed in real time and escalated if needed.
Where Is Loitering Detection Most Effective?
Loitering alerts are ideal for areas where people are not expected to stay for long.
Common use cases include:
- Hotels & Hospitality – lobbies, side entrances, staff-only zones
- Car Dealerships – forecourts, showroom perimeters
- Warehouses & Distribution Centres – loading bays, fire exits
- Schools & Colleges – perimeters, entrance gates
- Retail Premises – service corridors, loading areas
- Offices – receptions, stairwells, lifts
- Transport Hubs – platform zones, station entrances
- Petrol Stations – pumps
- 247 Environments – People are expected to pass through, not stay put
What Equipment Supports Loitering Detection?
To enable loitering alarms, your CCTV system needs the following:
Smart Cameras with Built-In Analytics
Manufacturers that offer loitering detection include:
- Hikvision AcuSense series (e.g. DS-2CD2646G2-IZS, DS-2CD2347G2-LU)
- Dahua WizSense/WizMind series
- Hanwha Vision (Wisenet AI range)
These cameras allow you to draw zones, set dwell times, and configure how the system should respond when loitering is detected.
Compatible NVR or VMS
Ensure your recorder or video management system can handle smart events:
- Hikvision NVRs (I-Series and above)
- Milestone XProtect
- Hanwha Wisenet WAVE
- HikCentral or Genetec platforms
3. Monitoring or Alert Configuration
For sites connected to a monitoring station like Farsight:
- Loitering alarms can be delivered in real-time
- Our team can escalate to your keyholders or on-site team if required
How to Set Up Loitering Detection (Hikvision Example)
If you’re using a Hikvision AcuSense camera, here’s a general step-by-step to configure loitering alarms:
Step 1: Log In to the Camera Interface
- Access the camera via its IP address in a web browser.
Step 2: Navigate to Smart Events
- Go to Configuration > Event > Smart Event > Loitering Detection.
Step 3: Enable Loitering Detection
- Tick Enable
- Draw the detection zone on the live view screen
- Set the dwell time (e.g. 30 seconds, 2 minutes)
- Adjust sensitivity if needed
Step 4: Set Linkage Actions
Choose how the camera should respond:
- Send Email
- Trigger Recording
- Notify Surveillance Centre
- Trigger Alarm Output (if connected to lights or speakers)
Step 5: Apply and Test
Click Save and perform a test by walking into the zone and staying beyond the dwell time. Check that the alert is received.
Note: If you’re using an NVR-only setup, ensure the smart features are available for that camera model and that you’re using the latest firmware.
Frequently Asked Questions (FAQs)
Q1. What’s the difference between loitering detection and motion detection?
A: Motion detection triggers an alert whenever there is movement in a defined area, including things like animals, trees, or shadows. Loitering detection, however, is behaviour-based. It only triggers if a person remains in a specific area for longer than a set time (known as “dwell time”), making it more accurate and relevant for security.
Q2. How long should I set the dwell time for loitering detection?
A: It depends on the environment. For example:
- In a hotel lobby, 2–3 minutes may be appropriate.
- In a forecourt or perimeter, even 30–60 seconds might be enough.
You’ll want to balance catching suspicious behaviour without triggering alerts for normal activity.
Q3. Can loitering alerts be monitored remotely?
A: Yes. If your system is connected to a remote monitoring station like Farsight, loitering alerts can be received in real-time. Operators can assess the situation live and escalate to keyholders or emergency services if needed.
Q4. What kind of cameras do I need to enable loitering detection?
A: You’ll need smart cameras with built-in analytics. Examples include:
- Hikvision AcuSense
- Dahua WizSense or WizMind
- Hanwha Wisenet AI range
Not all IP cameras support this feature, so check the model’s datasheet or contact your provider for confirmation.
Q5. Does my recorder (NVR) need anything special to support loitering alarms?
A: Yes. Your NVR should support Smart Events or AI Analytics and be running up-to-date firmware. Hikvision I-Series NVRs, for example, are a common choice for this.
Q6. What happens if my system doesn’t support loitering detection?
A: You still have options:
- Use intrusion detection + dwell time as a workaround (if available).
- Upgrade to a compatible camera or system.
- Speak to us at Farsight — we can help you review your current setup and recommend the best path forward.
Q7. Will loitering alerts cause false alarms?
A: Loitering detection is designed to reduce false alarms by focusing on behaviour, not just motion. However, you should carefully set up detection zones and dwell times to match your site’s usual activity to avoid unnecessary alerts.
Q8. Is loitering detection useful on 24/7 sites where people come and go all the time?
A: Yes — loitering detection is especially effective on 24/7 sites like hotels, car parks, hospitals, and transport hubs. These environments often have regular foot traffic, but people are usually just passing through. Loitering alerts can help flag when someone stays in a specific area longer than expected, for example, lingering in a stairwell, back entrance, or lobby at 3am. With the right dwell time settings, you can reduce false alerts while still catching unusual or concerning behaviour in real time.
