Edition 14 - Don't leave yourself blind with poor Camera Placement.

Welcome to edition 14 of Security Thoughts on Thursday where I hark back to another security system worry. This time its poor camera coverage.

I hope to find this brief weekly read on contemporary physical security issues interesting and thought provoking. If you do please feel free to share them with your colleagues and connections.

Don't Leave Yourself Blind With Poor Camera Placement

In the modern, constantly evolving business environment, ensuring the safety and security of your organisation requires more than just installing a few surveillance cameras. Understanding the proactive nature and importance of surveillance coverage is essential for business leaders, security managers, and risk professionals. A specially designed video surveillance system used proactively can aid in the early detection and response to potential threats and spare you the need to grapple with the aftermath.

This Security Thoughts on Thursday article briefly delves into the importance of comprehensive surveillance. It examines how blind spots compromise security and how site assessments combined with optimised camera placement can significantly boost protection.

Comprehensive Surveillance Coverage Matters.

Surveillance cameras are a cornerstone of any physical security strategy. Camera systems deter criminal activity, provide evidence in the event of an incident, and help monitor day-to-day operations. However, the real value of these systems hinges on their ability to provide comprehensive coverage. Gaps in surveillance, also known as blind spots or dead zones, can leave critical areas unmonitored, creating vulnerabilities that malicious actors can exploit. With complete surveillance coverage, every part of your facility, from high-traffic areas to secluded corners, is monitored. This all-encompassing approach helps deter potential threats such as break-ins, theft, or unauthorized access, and comprehensively records events. Without a doubt, complete coverage is invaluable for real-time security management and post-incident investigations if an incident occurs.

Does your surveillance system match your operational requirements (OR) and capture all areas of concern? If you have any doubts, your organisation could be at risk.

Blind Spots Threaten Your Security

Areas within your facility that your cameras don't see result from poor placement, insufficient cameras, or obstructions like walls, furniture, or landscaping. Do you know where your blind spots are?

Consider a poorly positioned camera overlooking a rear entrance, which leaves a blind spot in coverage of the door. This loophole allows an invader to pass through unnoticed. Similarly, a large object, like a sign or a tree, could obscure a camera's view of an entire area. Leaving someone free to move covertly through that area. These blind spots are not just security voids but potential points of failure in your overall security plan. They can lead to undetected criminal activities, loss of valuable assets, and even jeopardise the safety of your employees and customers.

The Role of Site Assessments

The first step to eliminating blind spots in your surveillance cover is to conduct a thorough site assessment. The assessment should align with your OR and involve a detailed evaluation of your facility's layout, identifying potential security risks, and determining the best camera locations. It's not just about randomly placing cameras but about strategically positioning them based on your facility's unique challenges and vulnerabilities.

During the site visit, a good security system specialist experienced in designing and implementing surveillance systems will examine various factors:

1. Facility Layout: Your facility's physical design, including the size, shape, and purpose of each area, will influence camera type and placement. For example, narrow hallways, expansive parking lots, and large open areas require different camera configurations.
2. High-Risk Areas: Certain parts of your facility may be more vulnerable to security threats. Your surveillance strategy should prioritise these high-risk areas.
3. Application: Obviously, camera resolution must be good enough to capture meaningful events in real time. However, it must also match the observation criteria, identification, recognition, monitoring, etc. Also, determine the camera functionality: fixed to provide continuous coverage or fitted with pan, tilt, and zoom to facilitate tracking and close inspection of an area of interest.
4. Obstructions: It is crucial to identify potential obstructions, such as pillars, shelving, or foliage. Cameras should be sited to avoid these obstacles, ensuring a clear field of view.
5. Lighting Conditions: Lighting plays a significant role in surveillance effectiveness. A site assessment will evaluate lighting conditions to ensure cameras capture clear images day and night.
6. Business Operations: Understanding your organisation's daily operations is crucial for determining where surveillance is most needed. For instance, constant oversight is essential in areas where cash transactions occur or sensitive information is handled to ensure the safety and security of your business. Other areas may benefit from event-driven monitoring.

Optimised Camera Placement Makes a Difference.

Once a site assessment is complete, what comes next? The key to effective surveillance lies in the strategic placement of cameras. Does your current setup strategically prioritise critical areas such as entrances and exits? Cameras should be strategically placed at all points where people can enter or leave, including secondary doors and windows. If someone tries to gain unauthorised access, will your system provide enough detail to catch them? What about areas where people move frequently, like lobbies, corridors, and stairwells? Cameras tactically located in these high-traffic areas capture potential incidents, help establish who was onsite, and monitor crowd control and movement patterns. How about high-risk areas like cash handling or data centres, are they adequately monitored?

To eliminate blind spots, explore using overlapping fields of view. This technique involves positioning cameras so that one camera's blind spot is covered by another camera, guaranteeing no area is left unmonitored. For example, suppose a pillar obstructs one camera's view. In that situation, another camera's view should cover the same area from a different angle, ensuring uninterrupted coverage. Additionally, the height and angle of your cameras are critical. Are your cameras installed high enough to prevent tampering but angled correctly to capture clear footage of faces and activities? Finally, are you using 360-degree cameras in larger, open areas like parking lots or warehouses? These cameras can provide full coverage without missing a thing.

Benefits of a Comprehensive Approach

What advantages can you expect from implementing comprehensive surveillance coverage? First and foremost, heightened security. By eliminating blind spots, you significantly raise the bar for potential miscreants to exploit weaknesses in your system. Moreover, full coverage ensures you to capture every detail and makes it easier for security teams to respond and investigate concerns. Your security team can use the footage to identify potential threats, track suspicious activities, and provide evidence for investigations. Furthermore, a comprehensive surveillance system can also enhance your business operations. Monitoring your facility's critical areas helps streamline processes, manage resources more efficiently, and ensure compliance with standards and protocols, fostering confidence in both your operations and security.

Is Your Surveillance System Protecting You?

Comprehensive surveillance is more than just a security measure. It's an investment in the safety and efficiency of your entire organisation. Failing to conduct a thorough site assessment and optimise your camera placement could leave your business vulnerable.

For business leaders and security managers, now is the time to ensure your surveillance system is up to the task. Don't wait for a security breach to uncover unexpected blind spots. Conduct site assessments, optimise camera placement, and proactively manage risks to protect your organisation.

Let's keep your business safe, one camera at a time.
