Why perimeter security is the first line of defense

Between October 2020 and October 2021, the number of property-related crimes in South Africa dropped by 7.7%.

This drop has been partly due to local businesses’ increased implementation of advanced security systems. Suppose you’ve not yet done the same but need to upgrade the perimeter security of your business. In that case, there are several options available, and understanding how they work is essential in deciding which method is best for you.

Read on to learn more.

What is perimeter security?

Every business should have a security system in place that protects against intruders. Perimeter protection is the first line of defense within any security system, making it arguably the most crucial part.

Stopping intruders at the first point of contact helps maintain the integrity of the rest of your security system and acts as a deterrent. If an intruder knows they can’t get past your first barrier, they are likely to assume that things will only get more complicated from then on.

Companies operate differently and therefore require unique security systems. However, some common security elements remain essential to almost all businesses, one of which is perimeter security.

Layered security

Sometimes known as the “onion ring” approach, this involves several layers of security covering a high-risk area. Layering security means that an intruder would have to get through all layers of the security system to access the most sensitive area(s) in the centre.

This system is more commonly suited to larger sites containing separate buildings and other elements, such as airports or ports.

Physical security

A physical perimeter barrier is one of the most simple yet effective layers of security you can have. Fences, barriers, gates, and doors are clear signs to anyone that they are not permitted to enter or access a particular area. These vary greatly and provide different levels of security.

Doors and gates should have suitable locks allowing access to only authorised individuals. Fences can be as high as needed, and you can also outfit them with extra deterrents such as spikes or razor wire.


CCTV is an integral part of any commercial security system. Having cameras around your site will act as a deterrent and help resolve issues if anyone decides to trespass. 24/7 monitoring of a site is possible, thereby providing video evidence in the event of a break-in and helping to identify any intruders and how they gained entry.

Daisy offers scalable and customisable CCTV solutions. Most of the time, we can integrate our system with the one already installed at a client, saving time and costs. 

Cameras can be placed all over a site for full coverage or, if that is not necessary, located in select areas such as entrances and exits.

CCTV cameras also allow you to monitor staff and assess performance and safety compliance within the workplace.

Installing a high-quality CCTV system reduces guarding costs and insurance premiums, thus saving costs in the long run. Also more straightforward are insurance claims as video evidence substantiates them.

Controlled access

A simple lock and key system may be sufficient, but access control can be more efficient for an advanced business security system. Daisy Solutions provide a range of security services, and our access control systems make it easy for you to control who has access to which areas of your site and when.

There are multiple access methods from which to choose. They include:

  • ID cards
  • Fingerprints
  • Facial Images
  • Passwords
  • QR Codes

All of the above can integrate with turnstiles, controllers, and door locks. Furthermore, their on-site configuration is set up precisely according to individual client requirements. We can scale these systems to suit the size of a business and cater for them to fit in with budgets and needs.

Intrusion detection

If someone does intrude on your site, you’ll want to be aware of it as soon as possible. Daisy offers various recording devices alongside security cameras, allowing you to review recorded camera footage whenever you wish.

We also offer a range of alarms and speakers to deter intruders and alert you when someone trespasses.


The human eye can only see visible light; however, cameras with thermal imaging can see what the human eye can not. They detect that which would otherwise be invisible. Thermal cameras can easily detect heat sources, provided they are humans, animals, vehicles, or the like.

In addition to this, they can monitor the temperature of components and machinery or detect gaps in thermal insulation. 

These images are vital to monitor and capture on record, especially in dark environments where visibility is low. They constitute essential information sources that could prove valuable in the future.


ANPR (Automatic Number-Plate Recognition) allows the identification of vehicles entering and exiting a site. ANPR can collect vehicle data and even control access, similar to the access control system mentioned previously in this article.

Systems are programmed to send alerts whenever a suspicious vehicle is spotted and provide an option to block specific number plates from gaining access. Law enforcement, industrial sites, shopping malls, business parks, and similar businesses find great value in these systems.
