Physical Series Part 1: Perimeter Security

Oct 28, 2019

Perimeter security refers to protecting the areas outside of your commercial buildings or structures, allowing access only to those who have clearance and preventing access to those who don’t. It can also include keeping people in, as in the case of prisons and state penitentiaries.

When considering your perimeter security plans, go beyond fencing and think big. Don’t limit your thinking to technology but don’t discount it either. Consider all potential threats, areas of vulnerability and what assets you are wanting to protect. Below are our top considerations for perimeter security at your place of business.

Technology - Video Surveillance, Intrusion Alarms, Security Cameras

Technology is a broad term that can cover a lot of ground, literally and figuratively. Since we are referring to the outdoors, keeping in mind nuisance alarms is important when working up your exterior electronic security plans. For example, if you’re in a windy environment, then sensor alarms may not make the most sense.

Something else to think about is the functionality of your existing business security system. Is it up to date and providing you with everything your particular business needs? This refers back to knowing the threats and vulnerable areas unique to your situation.

If you don’t have a security system, then the options might seem overwhelming. HD video surveillance systems with remote access, video monitoring and video verification service can be your 24/7 eyes but do you need all of the above? Intrusion alarms and security cameras have come a long way and we have experts who can help you narrow down the options most pertinent for your business. Call or email us for more information.

Locking Up

Do you know how many master keys there are to your buildings? Are you diligent about collecting employee access cards upon resignation or termination? Which locks are you using to prevent intruders?

Considering that the majority of locks sold at hardware stores are not secure, which lock you choose is important. Door locks, padlocks and the chain padlocks are hung on should be made of the highest quality, durable metals available. You want the thickest, strongest and most durable option but, buyer beware, there is a lock bumping technique that allows for opening locks with a special bump key. Since implementing keyless entry outdoors can be challenging, finding a bump-proof lock is key. Moral of the story: don’t forget to lock up but also don’t rest your laurels on it. Like most security strategies, it’s a multifaceted approach.

Walls & Fences

Walls have been used as security measures for centuries, not only to make things physically challenging but they provide a mental barrier to entry as well. Fences can have the same effect and have come a long way since the first chain-linked fence was created.

If you already have a security structure surrounding your property, check for weak areas. Assess whether something taller or more secure is needed (electric fencing, for example). Do you need a fence that curves out (to keep people out) or in (to keep people in)? Should it have barbed or razor wire at the top? Are there any objects near your fence or wall (a power line pole, for example) that would assist someone in getting in (or out)? While fencing may not be your primary form of security, is your property secure without one? On a related note, consider whether or not a security gate is needed.

Signage & Lighting

Creating signs directing employees, visitors and deliveries can make a big difference in lowering crime rates. The goal is to separate them where possible to reduce confusion. If you can designate a separate parking lot outside your secure perimeter for visitors, all the better. Warn all employees (especially the friendly ones) of holding the door open for unknown guests in unauthorized areas. Signs noting the forms of on-premises security being used can also be effective, just as you’d do at home with your Per Mar Security yard signs. That includes noting the use of physical security officer and/or mobile patrol units if you have them.

Lighting is easy to overlook or take for granted, especially if you’re not the one working the graveyard shift. And, with the days getting shorter, the sun will be setting before 5pm and criminal activity won’t have to wait for the graveyard shift. The best tip here is don’t stop at the facade of your building and its great lighting of your expensive company sign and pretty foliage; be sure all vulnerable areas are well lit!

Last but not least, when implementing your perimeter security plans, inform all staff so that everyone is on the same page. A united front is often the strongest offense! Contact us for more ideas or a free assessment of your business’s perimeter.
