CPTED Part 3: Territorial Reinforcement and Maintenance

By Kevin Whaley, CPP, Sr. Security Consultant at Kenton Brothers

Welcome to Part 3 of our discussion about Crime Prevention Through Environmental Design (CPTED).

In Part 1, I introduced the concept of CPTED and the importance of ensuring CPTED principles are considered when developing or enhancing your security program. In Part 2, we dove into greater detail on the concepts of Natural Surveillance & Natural Access Control. In Part 3 of the series, we will be looking at Territorial Reinforcement and Maintenance.

As a quick recap: in the first part, we touched on the four key overlapping concepts of CPTED which include:
  1. Natural Surveillance
  2. Natural Access Control
  3. Territorial Reinforcement
  4. Maintenance
In the second installment, we went into greater detail about the in’s & out’s of Natural Surveillance & Natural Access Control such as;
  • Natural Surveillance – the placement of physical features, activities and people in a way that maximized visibility from the surrounding environment.
    • WHY? It increases the threat of apprehension by taking steps to increase the perception that people can be seen.
  • Natural Access Control – Natural access control means controlling access to a site. People are physically guided through a space by the strategic design of streets, sidewalks, building entrances, and landscaping.
    • Clearly defines entryways and guides personnel to specific entrances that are well lit and overlooked by surrounding areas.
Just as a reminder, the overall goal in the successful implementation a CPTED plan of action, we must understand that all human space:
  • Has some designated purpose.
  • Has social, cultural, legal, or physical definitions (such as expectations or regulations) that prescribe the desired and acceptable behaviors.
  • Is designed to support and control the desired and acceptable behaviors.
With that understanding in mind, our approach should focus on:
  • Manipulating the physical environment to produce behavior effects that reduce the fear and incidence of certain types of criminal acts;
  • Understanding and modifying people’s behavior in relation to their physical environment
  • Redesigning space or using it differently to encourage desirable behaviors and discourage illegitimate activities; and
  • Reducing the conflicts between incompatible building users and building uses, with the goal of eliminating “no person’s land” that no one takes ownership of.

There are various controls that can be implemented that can supplement or support the approaches listed above.

CPTED Part 3: Territorial Reinforcement and Maintenance

Territorial Reinforcement and Maintenance of your CPTED program.

Territorial Reinforcement:

Territorial reinforcement involves establishing a sense of ownership and belonging in a specific space, which can be achieved through various design elements and strategies. When a space appears to be clearly defined and “owned” by a particular group or individual, it may discourage potential criminals by making them feel like trespassers or intruders and that the potential for detection is high.

Importance in CPTED: By implementing territorial reinforcement, CPTED aims to deter criminal activity by promoting the perception of active ownership and surveillance. A well-defined and cared-for area signals to potential offenders that their presence is likely to be noticed and that there is a higher risk of detection and apprehension. This may lead to a decrease in the opportunities for criminal acts to occur, as criminals tend to avoid spaces where they feel more vulnerable and exposed.

Examples of Territorial Reinforcement:
  1. Clear boundaries and property lines demarcated with fences, hedges, or other physical barriers.
  2. Well-maintained landscaping and exterior areas, indicating active use and care.
  3. Signage and symbols that represent community ownership or surveillance, such as neighborhood watch signs.
CPTED Part 3: Territorial Reinforcement and MaintenanceThese examples of territorial reinforcement can (and should be) enhanced with other physical security measures including but not limited to:
  1. Surveillance cameras
  2. Speakers with pre-recorded messages stating that the person is being watched or that authorities have been called.
  3. Sufficient illumination
  4. Security officers
  5. Access Controls
  6. Active/Passive intrusion sensors

However, no matter how advanced or intricate your CPTED program is, it can deteriorate and become obsolete without proper care and maintenance.

CPTED Maintenance:

CPTED maintenance involves sustaining a sense of ownership and control over a space through ongoing upkeep and community involvement. Neglected or poorly maintained areas can attract criminal activity as they signal a lack of guardianship and a reduced risk of detection.

Importance in CPTED: Regular maintenance of public and private spaces is critical to the success of CPTED. Well-maintained environments foster a sense of pride, ownership, and responsibility among community members. It reinforces the idea that residents are actively invested in their surroundings and are vigilant against criminal behavior. This collective effort makes it less attractive for criminals to target such areas, as they are more likely to be noticed and reported by the community.

Examples of Territorial Maintenance:
  • Prompt repair of broken windows, damaged fences, or graffiti.
  • Adequate lighting to ensure visibility and reduce hiding spots.
  • Community engagement and participation in the upkeep of shared spaces.

CPTED Part 3: Territorial Reinforcement and Maintenance


The image to the right is an example of POOR CPTED maintenance. As you can see, the vegetation is growing through the fence line, damaging it significantly and there are various areas where intruders have cut and recut through the fence line. The lack of prompt repair, landscaping maintenance, and lack of illumination, make this industrial facility a tempting target.

In conclusion, territorial reinforcement and maintenance are essential components of Crime Prevention Through Environmental Design. By creating a sense of ownership and responsibility within a community and ensuring that spaces are well-cared for, CPTED aims to discourage criminal activity and promote a safer environment for residents and visitors alike. These proactive measures empower communities to take control of their surroundings and play an active role in crime prevention.

I hope you will watch out for the final installment where we will review the concepts we’ve discussed and how they all can be tied together.

In September, Almost 500 Missouri Schools Received Safety Grant Awards

By Gina Stuelke, CEO of Kenton Brothers

2023 Missouri School Safety Grant AwardsFor Kenton Brothers, ensuring the safety and security of students, teachers, and staff in schools across the country is of paramount importance. In recent years, the need for robust physical security measures in school districts has become increasingly evident due to unfortunate incidents of violence and threats. One of our areas of expertise is commercial security solutions for school districts, and recent news about safety grant awards for Missouri schools caught our attention.

On June 30, 2023, Governor Mike Parson signed House Bill No. 2 for Fiscal Year 2024 (FY2024) which appropriated $50 million in funding for a second round of School Safety Grants to support physical safety improvements in local education agencies (LEAs) and nonpublic schools (NPSs) across the state. These funds will be distributed through the Department of Elementary and Secondary Education’s FY24 School Safety Grant Program. These grants were awarded to almost 500 Missouri schools in September. (For a complete list of Missouri schools receiving these funds, click here.)

10 Ways These Funds Could Be Used to Improve School Safety

2023 Missouri School Safety Grant AwardsThe Department of Homeland Security (DHS) has outlined various recommendations for enhancing school security. In this article, we discuss the top 10 physical security upgrades that school districts must consider implementing immediately, based on DHS guidelines.

1. Access Control Systems

One of the first and foremost security upgrades school districts should make is implementing an access control system. These systems restrict unauthorized entry into school buildings by requiring individuals to use credentials, such as key cards, PINs, or biometric data, to gain access. Properly designed access control systems can significantly reduce the risk of unauthorized individuals entering school premises and pose a crucial layer of school security. All Access control systems implemented in schools should include door position sensors to report when doors are propped open or forced open anywhere around the exterior of the building.

DHS Recommendation: DHS emphasizes the importance of access control systems to deter and detect intruders. Schools should consider a layered approach that includes access control points at all building entrances.

2. IP Video Surveillance Cameras

Surveillance cameras play a crucial role in monitoring school premises and deterring criminal activity. Modern cameras come equipped with advanced features such as high-definition recording, night vision, and motion detection. Placing cameras strategically in and around school buildings can help identify and document suspicious behavior.

DHS Recommendation: The DHS recommends schools install surveillance cameras at key locations, including entrances, hallways, parking lots, and outdoor areas. Additionally, schools should consider integrating their camera systems with an alarm monitoring service.

3. Intrusion Detection Systems

2023 Missouri School Safety Grant AwardsIntrusion detection systems are designed to detect unauthorized access to buildings and alert security personnel or authorities immediately. These systems can be connected to doors, windows, and other access points, triggering alarms in the event of a breach. Early detection of intruders is critical for swift response and mitigation.

DHS Recommendation: DHS encourages the use of intrusion detection systems and recommends regular testing and maintenance to ensure their effectiveness.

4. Bulletproof Glass and Ballistic Barriers

Incorporating bulletproof glass and ballistic barriers in critical areas of school buildings can provide an extra layer of protection against armed threats. These materials are designed to withstand various levels of impact and can buy precious time for security personnel and occupants during an active shooter situation. There have been large, innovative strides in this technology recently. These innovations include fire and escape improvements all allowing for quicker egress.

DHS Recommendation: The DHS recommends considering the use of bulletproof glass and ballistic barriers in areas such as main entrances and administrative offices.

5. Visitor Management Systems

A visitor management system is a digital solution that helps schools monitor and control visitor access. These systems require visitors to register upon entry, provide identification, and undergo background checks when necessary. By implementing visitor management systems, schools can better control who enters their premises.

DHS Recommendation: The DHS suggests that schools should have a clear visitor policy in place, including the use of visitor management systems, to enhance security.

6. Security Fencing

2023 Missouri School Safety Grant AwardsSecurity fencing is another essential security upgrade. It provides a physical barrier to deter intruders and prevent unauthorized access to the school grounds. Fencing can be combined with controlled entry points, surveillance cameras, and alarm systems to create a comprehensive security solution.

DHS Recommendation: According to DHS guidelines, school districts should ensure that fencing is properly maintained, adequately secured, and complements other security measures that are in place.

7. Security Lighting

Proper lighting can significantly improve the security of school premises, as it deters criminals and enhances surveillance capabilities. Well-lit areas also help students and staff feel safer when entering or exiting school buildings during dark hours.

DHS Recommendation: The DHS suggests that schools evaluate their outdoor lighting and consider upgrading to motion-activated lighting in vulnerable areas

8. Panic Alarms

In emergency situations, quick communication with law enforcement is vital. Panic alarms, often connected to local police departments, enable immediate alerts in case of threats or emergencies. These alarms can be discreetly activated by school personnel and trigger a rapid response from law enforcement agencies.

DHS Recommendation: DHS emphasizes the importance of panic alarms for notifying authorities in real-time during security incidents.

9. Lockdown Procedures and Hardware

2023 Missouri School Safety Grant AwardsEffective lockdown procedures are crucial for safeguarding students and staff during emergencies. Schools should invest in secure locks and hardware for classroom and office doors to ensure that they can be easily locked and barricaded from the inside during a lockdown. Training staff and students on these procedures is equally important.

DHS Recommendation: The DHS recommends that schools develop and practice lockdown procedures regularly, including drills and training sessions. They also advise installing locks that can be locked from the inside without requiring keys.

10. Security Training and Education

Last but certainly not least, the DHS strongly emphasizes the importance of security training and education for school staff and students. Ensuring that everyone is well-informed about security protocols, emergency procedures, and situational awareness can greatly enhance the overall safety of the school environment. Even the greatest systems will not have any value if the people that use them every day don’t understand how to use them effectively.

DHS Recommendation: Regular training and education programs should be implemented to teach staff and students how to recognize and respond to security threats effectively.

In Closing…

The safety and security of our schools must be a top priority. By following the Department of Homeland Security’s recommendations and implementing these top 10 physical security upgrades, school districts can create a safer and more secure environment for students, teachers, and staff. It’s essential for schools to remain vigilant, regularly assess their security measures, and adapt to emerging threats to ensure the protection of their educational communities.

Chain of Custody in Commercial Security

Chain of CustodyBy Ryan Kaullen, Field Services Manager at Kenton Brothers

Many of you know that our goal is to protect people, property, and possessions. Something that comes up related to this goal is Chain of Custody.

You may be wondering what Kenton Brothers has to do with Chain of Custody and how we would be involved. Unfortunately, part of the work we do in the commercial security industry is capturing evidence. This evidence comes in many forms. Evidence may include video surveillance recordings, security system audit trails and more. We capture this information to help protect companies from theft, fraud, and work place incidents. There are plenty of scenarios that result in law enforcement being involved.

What is Chain of Custody?

Chain of Custody is the documentation of chronological events related to an incident. Protection of how the evidence is handled, who handles it and more matters. The idea is that law enforcement needs to be able to review and use video and other forms of documentation as evidence in a trial or hearing.

A Recent Example for a Banking Client

Chain of CustodyWe recently received a Chain of Custody request from one of our banking clients. They had an event that they deemed legally significant and requested our help in documenting what had happened. They needed our help to get the video segments exported properly. They wanted footage from all of the cameras at one of their locations over the past 30 days. (That’s a good amount of video data!)

Our first step was to download the footage locally to external hard drives. The video data had to have password encryption. And the video footage had to be time stamped. We also had to fill out Chain of Custody paperwork.

On top of those requirements, the equipment and external drives couldn’t be left unsecured while we were downloading the video segments. We also had to be in an access-controlled room for audit purposes. It was crucial that we followed every step correctly to make sure their case against the accused is rock solid. We had to make sure the evidence we helped provide would not get thrown out due to Chain of Custody problems.

Once the video had been downloaded onto the drives, our technician had to hand deliver the hard drives to the bank’s lawyer and provide the Chain of Custody paperwork.

We Take Chain of Custody Seriously

Chain of CustodyChain of Custody is something Kenton Brothers takes extremely seriously for many reasons. One, we want to make sure we are providing our customers with a level of service and reliability they can count on. We also want to make sure law enforcement has what they need to support or refute claims. This is also a great example of how the commercial security systems we sell and support do what they’re supposed to do.

The reality is that you hope you never have to use footage, audits, etc. against someone working for you or coming in to your place of business. But when something does happen, you want to make sure you have the right systems in place to protect the people, property, and possessions of those who work there.
