Most business owners will only consider their business’s security after they’ve experienced some type of problem. For example, when they arrive at work Monday morning and find a rolling door has been left open. When they discover that items from one of their warehouses have gone missing. When a contractor enters a server room that was supposed to be locked. At this point, it is too late. You now need to deal with insurance companies, file a report with law enforcement, and speak to your employees/tenants in a way that is probably going to cause tension.
Here is what people rarely say: Every incident begins with a “gap.” An unlatched gate. A visitor that was never checked into the system. An unlocked door that was used to smoke. A security camera that was down for three weeks. The gaps are always there and wait patiently until an opportunist thief or a negligent employee discovers them.
The best use of security dollars is not to react more quickly to threats. The best use of security dollars is to identify vulnerability areas before they become large problems. This is where static security guards prove their value. Guards who are on-site, watching, checking and questioning can stop problems before they develop into major incidents.
This article is designed to provide you with a straightforward comparison between static guards and mobile security patrol services in Perth. We will be looking at how static guards are able to identify potential issues prior to becoming incidents, as well as the pros and cons of both options, such as costs, flexibility, area covered and response time. This guide is meant to help you determine whether static guards or mobile security patrols are best suited for your business’ size (small office, mid-sized warehouse or large commercial site) and budget. There is no fluff in this comparison – it is solely meant to assist you in making an informed decision about where your security dollars should be spent.
What Is a Security Gap?
The difference between what you believe is being protected and what you are protecting is called a security hole. Usually, it’s not a big deal. Most of the time it’s just a little thing that could easily be overlooked.
Common examples in Perth commercial properties include:
- Access Gaps: unsecure gates, piggybacking through the main door, and failure to return keys/access cards.
- Process deficiencies: no visitor log, no contractor sign-in, and no verification of individuals present on the premises during off-hours.
- Technology gaps – Cameras which have blind spots, Alarms that no one responds to, Lighting which is not working.
- Human gaps: staff who are unsure what to do when something looks wrong.
- The amount of time that passes from when the site closes until the next patrol or alarm response arrives at the location.
The final item is probably the least thought about. Businesses will purchase cameras and alarms, but they will fail to realize that detection is not prevention. An alarm will notify you when something occurs. However, a security guard on-site can prevent an event from taking place.
What Static Security Guards Actually Do
A static security guard remains stationed in a single area throughout his/her entire work day. This could include being stationed in front of the main entrance to a high-rise building, at the entrance to a warehouse facility, or within the common areas (lobbies) of a commercial property. While a patrolling officer will travel around to multiple locations during his/her shift, the static security guard has extensive knowledge regarding the layout and operation of your specific property.
Prevention starts with presence
The greatest advantage of a uniformed officer is probably its simplicity. It changes people’s actions. Most criminals will try to find an easier way into a building, and a guarded door is not an easy option. Employees and guests are more likely to follow rules and procedures if there is someone observing what they do. This includes filling out forms correctly or keeping fire escape doors free from obstacles.
Access control and visitor management
Static guards verify identification, log visitors into and out of the facility, confirm delivery of items to the proper location, and ensure that independent contractors remain within the designated work areas. These measures help close off the most common avenues for unauthorized entry into a facility.
Daily observation and early warning
The guards are based at the same site during all shifts, so they recognize changes. They will observe if a car has been parked in the same location for three consecutive days; if a section of fencing appears loose; if a door remains unlocked when it should be locked. Such localized understanding of a specific area can be difficult to replicate. Therefore, the guards’ knowledge of their environment can turn minor irregularities into early warning signs rather than unexpected events occurring on Monday mornings.
Rule enforcement and safety
The presence of a guard on a commercial property is useful for enforcing the regulations governing the operation of the site (i.e. high visibility gear requirements, access restrictions etc.). A guard can assist in responding to emergencies (i.e. evacuation management, assisting first-responders with directions, and providing first-aid care prior to the arrival of emergency personnel). The availability of a calm, trained individual on a fast paced commercial site is beneficial.
Reporting that improves security over time
The best part of being a static guard is having clear logs of everything that goes on. This includes who enters and leaves, what they do, and when issues are resolved. When you look back through your records over time, you will start to see trends. For example, if you notice that someone has been trying to get through the same gate after hours multiple times, then you can take steps to permanently resolve the issue instead of always reacting to the problem.
What Mobile Security Patrol Services in Perth Do
The way mobile security patrol services operate is very different than static guard services. A mobile security patrol officer does not remain static at a single site, rather he/she will drive around to various customer locations in a clearly marked vehicle, either during specified times or at random intervals.
A typical patrol visit includes:
- Checking doors, gates, windows and roller doors
- Walking the perimeter and inspecting for damage or intrusion
- Verifying that alarms, lights and cameras are working
- Moving on unauthorised people, such as loiterers or squatters
- Responding to alarm activations when contracted to do so
- Leaving a report or digital log of each visit
In addition to being a large city with a high level of dispersion, there are other reasons why mobile patrols are so commonly used in Perth. Industrial areas such as Welshpool, Malaga, Kewdale and Osborne Park have many warehouses and yards that require little or no guarding; however, they would benefit from being regularly checked on by mobile patrol officers. Mobile patrols can also provide the same benefits to office buildings and retail strips.
The main trade-off is easy. You get more coverage with patrols but it will cost less. On the other hand, you can get a higher level of security and always have someone there with static guards.
Static Guards vs Mobile Patrols: Quick Comparison Table
| Factor | Static Security Guard | Mobile Patrol Service | Hybrid (Both) |
| Presence | Continuous, on site for the full shift | Intermittent, visits at set or random times | Continuous at key times, patrols between |
| Typical cost | Highest (hourly, per guard) | Lowest per site (shared across clients) | Moderate to high, depending on mix |
| Flexibility | Fixed post and hours, but can be scaled for events | Very flexible, visit frequency easy to adjust | High, can shift the balance as needs change |
| Coverage | One location in depth | Multiple locations, broad perimeter checks | Depth at the main site, breadth across others |
| Prevention | Strong, stops access gaps in real time | Moderate, deters through unpredictability | Strongest overall |
| Response time | Immediate, already on site | Depends on distance, often 10 to 30 minutes or more | Immediate on site, fast backup |
| Site knowledge | Excellent, same person or team | Good but less detailed | Good to excellent |
| Best for | Offices, large warehouses, high-value or high-traffic sites | Small to mid warehouses, multi-site portfolios | Growing businesses, mixed-risk portfolios |
The correct answer for each row is determined by your risk tolerance, your available financial resources, and the physical characteristics of your land.
Cost Comparison
Cost is usually the first question, so let us be straightforward about it.
Static guard costs
The rate charged by static guards is based upon an hourly wage, therefore, you are paying for the time that one guard spends at your site. The rates for static guards in Perth depend on several factors, including: the award wage that applies to the guard; whether the guard has a license; what hours the guard works; if the guard works weekends and/or public holidays; and how much experience the guard needs to possess. A single guard who covers all shifts (i.e., 24/7) will require multiple guards to cover each of his/her shifts. Therefore, the annual cost of a 24/7 single guard could easily exceed $100,000. Conversely, a single guard who only covers business hours and/or evening shifts would be significantly less expensive.
The worth lies in what is purchased with those expenses: continuous availability, access management, and prevention of issues as opposed to reacting to them.
Mobile patrol costs
In general, mobile patrols have been offered at two pricing methods: per visit or as part of a package (such as several checks per night). As the officer and vehicle are shared among several clients, the cost per location is significantly less. For example, a small business could pay a relatively minor amount weekly to receive a few checks per night; whereas a large site would likely require both random patrols and alarm response.
What drives price up or down
- Frequency: more visits cost more.
- Hours: nights, weekends and public holidays carry penalty rates.
- Site size: large perimeters take longer to check.
- Extras: alarm response, keyholding, reporting software and dog handlers will increase the total cost.
- Contract length: longer commitments often attract better rates.
The cost of not acting
It’s simple to compare two different quotes and overlook the last column, which represents the costs associated with incidents. Costs such as stolen stock, damaged equipment, increased insurance premiums, lost productivity, and damaged customer confidence can quickly add up to more than one year’s worth of security expenditures. Think of security guarding as a method of managing risks rather than an expense item. Additionally, always ask for written estimates from licensed companies; this will help you determine the exact price based upon your specific location.
Flexibility Comparison
Business environments can evolve. When your business changes, such as adding another work shift, opening a new location, hosting a large-scale event, or having a slow period, your business’s security requirements will need to adapt accordingly.
Mobile patrols are naturally flexible
A simple telephone call will increase the number of nightly patrol visits from two to four. Patrols can be temporarily stopped during shutdowns, and if projects run late, weekend patrols can be added. It is more difficult for offenders to anticipate random patrol patterns than scheduled ones; therefore, these random patterns provide an inexpensive form of deterrence.
Static guards offer targeted flexibility
Static posts are more permanent because the security guard is assigned to one location during a specified period of time. However, excellent security companies can provide additional support when needed, such as for events, construction project milestones, new products being launched, and other high-risk times (e.g., the days before Christmas). Additionally, you may vary the responsibilities of your static posts. For instance, you could have a guard perform access control during the daytime hours and conduct perimeter checks at night.
Contracts matter
Ask about notice periods, minimum terms, and the ease of changing your hours. A less expensive price but a less flexible agreement could end up costing you more than a more expensive option which has some flexibility.
Coverage Comparison
The concept of coverage relates to two things – what amount of area is covered (or protected) by the service, and for what duration of time will the service provide protection.
Time coverage
A static guard will be present during the entire time of his/her/their shift. Mobile patrols are present only when they are physically located at the client’s location. For example, if a patrol comes to your home or business at 10 PM and then returns to your home/business at 2 AM; there will have been a 4-hour period of time where an intruder could enter your home/business without being seen by anyone. Randomizing the patrol visits to your home/business can help reduce this risk, however it cannot completely eliminate this risk.
Area coverage
A static guard who is stationed at the front gate can clearly view the entrance; however, he/she may have difficulty viewing the rear fence line. A mobile patrol officer covers the entire property line, checks the back lots, and inspects areas that a static guard cannot go beyond. Properties with large yards and multiple buildings are particularly suited for this type of security.
Where gaps hide
The reason why a combination of different security measures works so well is because static guards can provide immediate response to potential security threats at critical times; patrols can cover larger areas of your property during other periods; and technological systems (such as CCTV cameras, alarm systems and access control) will fill in the gaps until a person responds to the trigger.
Response Time Comparison
When something goes wrong, minutes matter.
Static guards: already there
On-site guards respond within seconds. Guards have many options for dealing with suspicious activity; they may confront the individual, contact law enforcement, close off parts of the building, and/or help other employees as necessary prior to a problem becoming larger. For businesses that deal with sensitive information (e.g., offices) or high value inventory (e.g., warehouses), the rapid response of on-site security is difficult to match.
Mobile patrols: depends on distance
The time it takes for patrol response will depend on the location of the vehicle when your alarm goes off, the amount of traffic on either the Kwinana or Mitchell Freeways, and the number of other clients being responded to at that moment. This means that, in terms of actual patrol response times, they may vary greatly – from just a few minutes up to approximately 30 minutes. Therefore, you should ask each potential security provider what their average alarm response time is in your area, and if this is part of their written agreement.
Prevention beats response
The primary advantage of static guards over mobile patrols is that even the quickest reaction from a mobile patrol is still a reaction. A static guard that prevents entry of an unauthorized individual at the door has effectively eliminated the potential for the incident. Patrols can both provide deterrence and detection capabilities; however, the benefit of continuous presence is greater in terms of prevention.
Which Option Fits Your Business Size?
Small offices and single-tenant premises
The majority of small businesses do not require a full-time security guard. The main security risks are typically associated with after hours break-ins, vandalism and loitering. A mobile patrol that makes several stops throughout each evening along with a monitored alarm system is generally the most practical and cost-effective option for many. However, if your business handles sensitive client data and/or has frequent walk-in customers/guests then you may want to look into employing a part-time receptionist/concierge security guard during your busiest times.
Mid-sized warehouses and industrial units
Theft of merchandise and/or equipment is a significant problem for warehouses. Loading docks, roll-up doors, and yards provide thieves with easy access points. Many warehouses use overnight mobile patrols in conjunction with static guards during times that pose an increased risk to loss (e.g., peak dispatch seasons, or if high-value merchandise is present in the warehouse). When a warehouse operates on a 24-hour basis, a static guard located at the gatehouse can control both vehicle and driver entry/exit, which will address one of the largest vulnerabilities in logistics security.
Large commercial properties and shopping or office complexes
Larger properties have a higher number of individuals entering, multiple access points, and therefore a greater amount of legal liability. A layered level of security coverage is necessary for such properties through a combination of static security personnel located at the primary entry point(s) and control center, in addition to mobile patrols and CCTV systems. Property managers should additionally plan for an emergency response as having a trained security officer present can be very beneficial when evacuating.
Multi-site businesses
If you operate multiple smaller sites within Perth (e.g. depots, retail stores, storage units), a mobile patrol will typically provide the most economical means of maintaining a uniform level of security. Static guards may be added only at the highest risk location(s).
The Hybrid Approach: Best of Both
For many Perth businesses, there is no right answer when it comes to static vs. mobile. Both have their advantages and disadvantages depending upon how much risk is associated with each type of business operation.
A hybrid model might look like this:
- A static guard during business hours to manage access, visitors and deliveries
- Mobile patrols overnight with randomised timing
- Monitored alarms and CCTV with a clear response plan
- Monthly reporting to review incidents, near-misses and weak points
This multi-tiered method provides you with an instant presence during peak traffic periods, as well as affordable coverage for off-peak hours. Additionally, this method creates a feedback loop which will allow you to close gaps as they appear. You can also make changes to the number of gates used based upon the activity of the site. For example, if there are multiple attempts at entering through a single gate, you can install a permanent gate at that location. Conversely, if a site remains relatively inactive, you can reduce the amount of time that employees work at the site, saving you money.
How to Choose a Security Provider in Perth
No matter which model is selected, the provider is equally important to the type of service provided. This checklist can be used.
- Confirming that the company has valid Western Australia security license for all of their employees.
- Insurance: Ask for proof of public liability and workers compensation cover.
- A good provider will go over your site and find out what is missing from it before they give you an estimate of how much it will cost. They don’t send you a generic price.
- You must have clear service levels in writing (patrol frequency, response times and reporting standards).
- Reporting: Ask how you will receive logs and incident reports, and how quickly.
- Guard Quality: Ask about their training, supervision and how they manage absenteeism so you will always have someone posted.
- Perth-based team has knowledge about local traffic, industrial areas, and common risk.
- References: Speak to existing clients of a similar size and industry.
- Contract terms: Check notice periods, minimum terms and how changes are handled.
Do not trust prices that seem too low. When a quote seems too good to be true, it may mean that the company has very little oversight, frequent staff changes, or additional fees that are hidden from view.
Common Mistakes Businesses Make
- Buying security for compliance. A security guard or patrol that does not address your specific security needs, is money down the drain.
- Camera/alarm reliance only; technology detection/people prevention/response.
- Ignoring after-hours risk. Most break-ins happen when nobody is watching.
- Never reviewing reports. Logs only help if someone reads them and acts.
- Set it and forget it. Your business is constantly evolving, therefore you need to assess your security program at minimum once per year.
- Choosing on price alone. The cheapest service is rarely the cheapest outcome.
- Employee Awareness Skipping. Employees should understand the rules, secure property, and report concerns for guards to perform well.
Security events do not just appear. They evolve from the small spaces that were not closed (an open gate, a missed registration, a long period of time between patrols). Static security guards close these spaces through presence, observation, and access controls. Mobile security patrol services in Perth expand on the benefits of static security guards to cover larger geographic areas and multiple sites at a reduced expense.
For smaller office spaces, a combination of patrolling and alarm monitoring may be sufficient for you. A balance between patrolling and focused static guard positions works well for medium-sized warehouses. Large scale commercial facilities will typically require multiple layers of protection that includes a solid base of static guards to provide effective security. Regardless of what type of security you decide to implement, first take an objective assessment of what areas within your business are unprotected, then base your security plan on filling those gaps before they become issues.
A licensed Perth security provider can assess your site if you’re trying to decide between different options for your warehouse, office, or commercial space. It’s much cheaper to close off potential vulnerabilities than it is to recover after an incident.
