Security Guard vs Camera Tower Cost: Which Wins in 2026?
Security guard vs camera tower cost compared: a manned guard runs €4,000-6,000/month, while a mobile tower starts at €14,800. See the full break-even maths.

When you compare security guard vs camera tower cost head to head, the numbers are stark: a single manned guard typically costs €4,000-6,000 per month, whereas a mobile camera tower (video tower) starts from €14,800 as a one-off capital purchase and then runs on power and connectivity alone. For any site that needs cover for more than four to six months, the tower is usually the cheaper option — and for round-the-clock coverage, the gap widens dramatically. This guide breaks down the true cost of each model so procurement and security managers can decide with confidence.
How much does a security guard actually cost?
The advertised hourly rate is only part of the story. A manned guarding contract that appears to cost €25-35 per hour rarely reflects the fully loaded figure once you account for shift patterns, overtime, holiday cover, sickness, and supervision.
The critical point is coverage. One guard cannot watch a site 24/7. True continuous cover requires roughly 4.2 full-time equivalents to fill a single around-the-clock post once rest breaks, weekends and annual leave are factored in. That is why 24/7 manned guarding at a single point of presence frequently exceeds €15,000-20,000 per month.
Industry surveys of the manned guarding sector consistently report annual staff turnover above 25%, meaning the guard patrolling your site this quarter may not be there the next — with retraining and familiarisation costs passed back to you.
What does a mobile camera tower cost to run?
A mobile surveillance tower (also called a video tower or CCTV tower) is a self-contained mast carrying thermal and optical cameras, motion analytics, floodlighting and loudspeaker deterrence. It watches a defined perimeter continuously and escalates only verified events to a monitoring centre.
Because the tower is bought once, the recurring cost collapses to power, a data SIM and periodic maintenance — typically a few hundred euros a month rather than several thousand. A single tower can also cover a wide field of view that would otherwise require multiple guards to patrol on foot.
Security guard vs camera tower cost: the direct comparison
The table below frames the three modern options against classic manned guarding. Capital items are one-off; guarding is a recurring monthly spend.
| Model | Entry cost | Ongoing monthly cost | 24/7 coverage | Weather/fatigue risk | |---|---|---|---|---| | Manned security guard | — | €4,000-6,000 per guard (one shift) | No — needs ~4 guards | High (fatigue, sickness, turnover) | | 24/7 manned guarding | — | €15,000-20,000 | Yes | High | | Mobile camera tower | From €14,800 | Power + SIM + maintenance | Yes | None | | Autonomous security robot | From €78,000 | Charging + service | Yes | None |
The autonomous security robot from BOSWAU + KNAUER adds a mobile, patrolling layer on top of the fixed tower — it moves through a site, inspects assets and responds to alarms without a human on the ground, which is decisive for larger or higher-risk perimeters.
When does a camera tower become cheaper than a guard?
The break-even point is the number of months at which the one-off tower price is repaid by avoided guarding fees.
At €14,800 for a tower versus roughly €5,000 per month for a single day-shift guard, the tower pays for itself in under four months. Against a full 24/7 manned post at €18,000 per month, a tower pays back in a single month. From that point on, the tower is effectively free security relative to the guarding baseline.
For a robot at €78,000 measured against a 24/7 manned team, the typical payback still lands inside a year — after which the operational saving compounds year on year, hardware depreciation aside.
Does a tower or robot deliver better security than a guard?
Cost is only half the decision; detection quality is the other half. A camera tower and an autonomous robot bring capabilities a human simply cannot match at scale:
- Consistent vigilance — no fatigue, no blind spots at 3 a.m., no smartphone distraction.
- Thermal detection — intruders are spotted in total darkness, fog and heavy rain.
- Instant audit trail — every event is recorded, timestamped and exportable for insurers or police.
- KRITIS-grade reliability — engineered for critical infrastructure, energy sites and utilities that demand 24/7 assurance.
Analyses of construction and industrial sites regularly attribute the majority of theft and vandalism losses to hours when the site is unstaffed. Continuous automated surveillance closes precisely that window.
Frequently Asked Questions
Is a camera tower cheaper than a security guard?
For anything beyond a few months of coverage, yes. A tower from €14,800 is a one-off cost, while a guard runs €4,000-6,000 per month and cannot cover the site alone around the clock. Break-even against a single guard typically arrives in under four months, and against a 24/7 manned post in about one month.
Can a video tower fully replace manned guarding?
For deterrence, detection and verified-alarm response, a mobile tower replaces most of what a static guard does — continuously and without fatigue. Where a physical presence or patrol is required, the autonomous security robot adds a moving layer, and both can be paired with a remote monitoring centre for human decision-making only when an event is confirmed.
What are the ongoing costs after buying a tower or robot?
The recurring spend is limited to power or charging, a data connection and scheduled maintenance — generally a few hundred euros per month, versus thousands for staffed cover. There is no overtime, no sickness cover and no staff turnover to fund.
Which sites benefit most from a robot or tower?
Construction sites, logistics yards, solar and energy installations, KRITIS-classified infrastructure and any large or remote perimeter where 24/7 manned cover would be expensive or impractical. These are exactly the settings where the cost gap between guarding and automation is widest.
The modern alternative to classic guarding
BOSWAU + KNAUER has manufactured security technology since 1892 in Filderstadt. Our mobile camera towers (from €14,800) and autonomous security robots (from €78,000) deliver KRITIS-capable, 24/7 protection at a fraction of the running cost of manned guarding — with better detection in darkness and bad weather, and a complete evidential record of every event.
