What we’ve learned about after-hours security – from family-owned businesses to Fortune 500s, by Tanner LaRocque, Director of Sales & Marketing, Evolon.
Talk with a security executive at just about any organisation – from a single-site car dealership to a sprawling Fortune 500 logistics hub – and ask them how they secure their property after hours.
You’ll almost always hear one of three responses.
As a company focused on perimeter protection, we regularly engage in these discussions. And while each site is different, the pain points aren’t.
From alarm fatigue and soaring guard costs to underutilised surveillance systems, the core security challenges are surprisingly consistent across industries and sizes.
This article serves as a field guide, drawing on insights from what we’re hearing, what’s working and how organisations are reevaluating their approach to after-hours protection.
The three most common after-hours setups
- In-house SOC teams – “We’ve got a SOC that actively monitors all sites after hours.”
This is the answer that we typically hear from enterprise teams, and it sounds ideal on paper. However, within the SOC, teams frequently encounter the same challenges that plague traditional central stations: Overwhelming volumes of video and intrusion alarms, excessive false alerts and the task of quickly identifying genuine threats.
The top complaints we hear from these teams are:
- False alarms (from legacy motion-triggered VMS setups)
- High staffing costs (running 24/7 shifts, paying for trained operators)
- Disconnected systems (video, intrusion, access control, dispatch – all siloed)
Operators are drowning in data and need clarity on what matters for efficient security operations.
On-site contract guards
“We contract with a guard service to patrol the site after hours.”
This is another common approach. Physical presence is valuable; something is reassuring about a human deterrent.
However, the cost of guards has been steadily increasing and many organisations are questioning whether the value is keeping pace with the expense.
Here’s what we regularly hear:
- Rising guard rates year-on-year
- Inconsistent quality of service
- No real integration between guards and the technology stack
- Limited coverage (a patrolling guard only sees what’s in front of them)
This last point is especially critical for large properties – think manufacturing facilities, multifamily housing, distribution centres or automotive groups. You can’t expect a single guard to monitor multiple acres effectively. Most sites end up with numerous guards per shift, driving total annual costs into six or seven figures.
No real plan – just forensic video
“Our cameras record motion, and if something happens, we’ll see it in the morning.”
Finally, there’s the reactive approach – which is more common than you’d think. Many organisations rely on video surveillance solely for forensic purposes. If a break-in occurs, they retrieve the footage, generate a police report and handle insurance claims.
The challenges here are obvious:
- Too little, too late – the crime already happened
- False alerts from basic motion detection
- Ongoing maintenance of outdated intrusion systems
- False alarm fines that chip away at already tight budgets
We understand that many of these intrusion and video surveillance systems were state-of-the-art when installed. They still serve a purpose, but when they become the only line of defence, the risk multiplies.
What’s working?
We’ve been fortunate to partner with organisations across each of these categories and we’ve seen meaningful transformations when they adopt a tech-forward approach to perimeter protection. Here’s what we’ve learned:
- For in-house SOCs – use AI to filter the noise
You don’t need to overhaul your SOC – just help your operators focus on the right things. By enabling better threat detection at the edge (for example, directly on the cameras) and layering in cloud-based computer vision, we’ve helped teams reduce false alarms by 90% with cloud AI alone.
When combined with our edge-to-cloud approach, the reduction reaches up to 98%. That means operators only receive alerts that matter – filtered, verified and prioritised.
It’s like handing your SOC team a set of noise-cancelling headphones for the alarm stream. The result? Less fatigue, faster response and lower costs.
For guarded sites – augment, don’t just replace
We’re not here to bash security guards. But, when a single person is expected to monitor an entire site with no access to real-time camera views or alerts, you’re setting them up to fail.
We’ve worked with automotive groups, for example, where multiple guards were patrolling lots after hours.
By embedding AI into the video surveillance system, adding strobe lights and speakers and enabling mobile alerts, we have helped create a hybrid guarding model – without sacrificing protection.
This approach can help drive a ROI exceeding 2,000% in some scenarios. It’s not about removing the human; it’s about empowering them with visibility and verified intel.
For sites with no plan – retrofit without replacing
Organisations without a proactive security plan don’t need to start from scratch – and they don’t need to rip and replace the systems they already have.
In most cases, we overlay our AI-driven threat detection onto their existing video infrastructure and intrusion panels.
By integrating with the alarm system, we not only eliminate false alarms through AI validation, but also put the panel to work – automating the arming and disarming of video monitoring schedules and tying the entire perimeter protection strategy together.
Verified alerts are routed to our central monitoring station, where trained operators confirm threats in real-time, issue live audio warnings, trigger strobes and call dispatch when necessary.
This approach turns static, forensic-only camera setups and aging alarm systems into an intelligent, unified perimeter defense – all without the cost or complexity of a complete system overhaul.
Field takeaways: Lessons that stick
False alarm fatigue is real
In most environments, over 90% of alerts are false positives – caused by motion, lighting, animals or environmental triggers.
It’s not just annoying; it’s dangerous. Teams that learn to filter effectively can unlock massive operational efficiency.
Guard costs are rising and expectations are too
A recent report from the Bureau of Labor Statistics shows that the median hourly wage for security guards has increased by over 20% in the past five years.
Meanwhile, service expectations haven’t changed and tech adoption is still limited. The math no longer adds up.
Legacy systems aren’t the problem – lack of integration is
Most intrusion systems in use today were built for a different era. While they may not be cutting-edge, they can still be part of a modern security stack.
The key is in connecting them with video intelligence and human response, not abandoning them entirely.
A smarter perimeter strategy
There’s no silver bullet in security. Every site is unique. But, after listening to hundreds of business leaders across verticals, a few universal truths have emerged:
- False alarms are not just a nuisance – they’re a liability
- Guards can’t do it alone. And in many cases, they shouldn’t have to
- “Record now, review later” is not a strategy – it’s a risk.
What’s needed today is a smarter, tech-first approach to after-hours protection. One that layers machine intelligence with human judgment.
One that makes your existing infrastructure work harder. And one that helps your team sleep better at night – literally.
