How to Configure Your Surveillance System to Avoid Patrol/Touring Loops170

In the world of security surveillance, patrol or touring routes, where cameras sequentially switch between pre-defined views, are a common feature. While offering a seemingly comprehensive overview, these looping patterns can be inefficient and even detrimental to effective security monitoring, especially in larger spaces or with dynamic environments. This article explores the drawbacks of patrol routes and provides a comprehensive guide on how to configure your surveillance system to avoid them, optimizing your security strategy instead.

Why Avoid Patrol/Touring Loops?

The primary issue with patrol routes is their predictability. A criminal or intruder, once familiar with the patrol pattern, can easily exploit the gaps in coverage created by the camera’s sequential movement. They can choose to act during the period when a particular area is not under direct observation. This predictability renders the system less effective than it could be with a more dynamic approach. Further, constantly switching camera views can lead to "camera blindness" among monitoring personnel. The rapid succession of images can make it difficult to process information effectively, potentially leading to missed incidents or delayed responses.

Moreover, patrol routes often necessitate the use of PTZ (Pan-Tilt-Zoom) cameras. While PTZ cameras offer flexibility, their constant movement can cause unnecessary wear and tear, potentially shortening their lifespan. The mechanical components are subjected to continuous stress, increasing the likelihood of malfunctions and requiring more frequent maintenance.

Alternatives to Patrol Routes: Strategies for Effective Surveillance

Instead of relying on pre-programmed patrol routes, security professionals should explore more sophisticated and proactive methods to maximize surveillance effectiveness. These include:

1. Strategic Camera Placement: This is the cornerstone of any effective surveillance system. Careful planning and consideration of blind spots, high-traffic areas, and potential intrusion points are crucial. Multiple fixed cameras strategically positioned can provide superior coverage compared to a single PTZ camera on a looping patrol. Consider using a combination of wide-angle and narrow-angle lenses to capture both a broad overview and detailed close-ups.

2. Event-Triggered Recording and Alerts: This involves configuring your surveillance system to record only when a specific event occurs, such as motion detection, intrusion alarms, or changes in temperature. This significantly reduces storage requirements and facilitates more efficient review of footage, focusing attention on actual incidents rather than continuous, irrelevant recordings.

3. Intelligent Video Analytics: Modern surveillance systems offer powerful video analytics capabilities. These include features such as object detection, facial recognition, license plate recognition, and loitering detection. These analytics can automate the monitoring process, triggering alerts only when a predefined event is detected, eliminating the need for continuous monitoring of numerous camera feeds and allowing for more focused attention on important events.

4. Hybrid Approach: Combining Fixed and PTZ Cameras: A blended strategy leverages the strengths of both fixed and PTZ cameras. Fixed cameras provide constant coverage of critical areas, while PTZ cameras can be deployed strategically for more dynamic observation or investigation upon an alert. The PTZ camera would only be activated when needed, thus avoiding the wear and tear and inefficiency of continuous patrolling.

5. Virtual Patrols: Some advanced systems offer virtual patrol features that mimic the functionality of physical patrols, but without the limitations. Instead of physically moving the camera, the system switches between pre-selected camera views on a flexible schedule, responding to events and allowing for greater control over the sequence and duration of each view. This allows for pre-emptive monitoring of high-risk areas without the drawbacks of continuous mechanical movement.

Configuring Your System to Avoid Patrol Loops: Practical Steps

The specific steps to disable or avoid patrol loops will vary depending on your surveillance system's make and model. However, general steps usually involve accessing your DVR or NVR's settings through its interface (typically web-based). Look for options related to "patrol," "tour," "preset," or "cruise" functions. Within these settings, you should find the ability to:

* Disable the patrol function entirely: This is the simplest solution if patrol routes are deemed unnecessary.
* Delete existing patrol routes: Remove any pre-programmed routes if they are no longer effective or efficient.
* Modify existing routes: Adjust the timing, sequence, and dwell time of each camera view to better suit your needs.
* Create custom schedules: If some level of scheduled monitoring is still needed, create a more flexible schedule that responds to potential threats instead of a rigid loop.

Conclusion:

While patrol routes might seem like a straightforward solution for surveillance, their inherent limitations often outweigh their benefits. By strategically deploying cameras, leveraging video analytics, and adopting a more event-driven approach, security professionals can create a significantly more effective and efficient surveillance system that proactively identifies and addresses security threats, without relying on outdated and inefficient patrolling techniques. Remember to consult your system's manual for specific instructions and always prioritize security best practices.
