Construction site security. Your site, protected 24/7. Watch it from anywhere.

AI-powered monitoring and live operators who stop theft, vandalism, and safety incidents before they cost you a project day.

(Based on a reviewed sample of 200 verified intrusion events across 60 monitored client sites, July 2023 to June 2026.)

Construction site security is the combination of AI video detection, live operator monitoring, and on-site deterrence used to protect equipment, materials, and workers on an active or dormant jobsite. Sirix delivers it as a fully managed service: AI flags the event, a trained operator verifies it on live video, and that operator intervenes by voice, siren, or dispatch before anything is taken. Sirix monitors 25,000+ devices across 230+ cities in Canada and the United States.

The reality of the jobsite

You can't watch every corner. Thieves know it.

The generator was there Friday at 5pm. By Monday morning, it’s gone. Along with the copper wiring, three power tools, and another week off your schedule. Construction theft clusters on nights, weekends, and long holiday weekends, when sites sit empty. The National Equipment Register tracks recurring national spikes around Memorial Day, Labor Day, and Thanksgiving. Traditional cameras record it. Sirix stops it.

Theft strikes when no one is watching

One incident can derail your schedule

Once it's gone, it's not coming back

Every hour covered. Day shift or dead of night.

Sirix covers construction sites through both halves of the day. During active hours, operators handle site compliance, access control, and full operational visibility from first truck in to last worker out. After the last worker leaves, the same operators take over the empty site, watching every corner and ready to act the moment something moves.

How it works

How does construction site monitoring work?

From first call to a monitored site, here is the whole process.

We design the coverage

Tell us about your site, its access points, and its phase of build. We work out which zones matter, where devices go, and what each one needs to detect. You do not need to know any of that in advance.

Your site goes live

Autonomous Security Boxes mount on poles or walls, or we connect to the cameras you already have. No trenching, no network cabling, no trades, no downtime. Everything is configured remotely and you are live within 48 hours of setup.

AI watches the perimeter

20+ AI detection models monitor your site continuously and filter out 95% of the noise before a human ever sees it.

A person verifies every event

A trained operator reviews the event on live video and decides the response using your site’s predefined procedures. Nothing is escalated automatically.

The operator intervenes

A live voice warning through on-site speakers, siren and strobe, a call to your team, or police dispatch. Whatever your procedures call for, on the schedule you set.

You get the record

Every event is timestamped, logged, and exportable for insurers, lawyers, and project owners.

The only thing you decide is how you want each situation handled. We follow your procedures exactly, on every event, around the clock.

Built for the risks construction sites face every day.

From stopping theft before it happens to keeping workers safe and giving you full visibility from anywhere, Sirix covers every shift, every zone, and every risk your site faces.

Remote video monitoring

Respond to every threat in seconds

When AI detection flags an event on your site, a Sirix operator is on it immediately. They assess the situation in real time and take action fast: voice intervention, siren activation, or direct escalation to authorities. All within seconds, all following your site protocols.

Every response is human verified before action is taken. No false alarm dispatches, no delays. Just trained operators making the right call, every time.

Voice interventions and deterrents

Stop intruders before they take a single step further

The moment an operator confirms a threat, they speak directly to the intruder through on site speakers in real time. Sirens and strobe lights activate simultaneously across the perimeter. In most cases, that is all it takes.

A live voice, a strobe, a siren. Not a recorded message. A real Sirix operator stopping the situation before anything is touched or taken.

Remote gate control

Control who enters your site without being there

Sirix operators manage your site gate remotely around the clock. Contractors and deliveries are verified and logged during the day. After hours, anyone arriving is identified and credentials checked before access is granted.

Operators follow your site protocols exactly. When your procedures call for it, cleared personnel can be visually escorted via on site cameras, creating a complete verified record of every visit.

Lone worker alarm response

Protect every worker on site, even when they are alone

Isolated workers in remote zones, late shifts, or after hours situations represent a real safety and liability exposure. When a lone worker triggers an alarm, Sirix operators respond immediately, follow your emergency SOPs, and coordinate the right help without delay.

A slip, a medical event, an unsafe situation. Whatever the reason, your worker is never without backup. Sirix bridges the gap between an incident and a response.

Continuous monitoring

Catch what cameras alone never would

Sirix operators assigned to your site learn its normal rhythm. The regular faces, the usual flow, the expected activity. That deep familiarity is what lets them spot what does not belong the moment it appears, well before it escalates into an incident.

High activity, high value sites generate constant movement. Most of it is normal. Some of it is not. A subcontractor accessing areas outside their scope, equipment gradually moved toward an exit over several shifts, a recurring PPE violation on a specific crew, tension between contractors escalating on camera. None of these fire an alarm. All of them get caught by a trained Sirix operator who has learned your site, knows what belongs, and applies the kind of human judgment and discernment that no AI can fully replicate.

Time-lapse

Document every stage of your build automatically

Sirix compiles daily site progress into shareable time-lapse footage automatically. Your clients get professional progress updates without extra effort on your end. Your team gets a timestamped visual record of every stage of the build.

Disputes over completed work, delays, or site conditions are resolved faster when the footage already exists. Time-lapse pays for itself in client confidence and in the claims you never have to fight twice.

Sirix mobile app

Run your site from your phone, tablet, or laptop

Arm or disarm your site remotely, view live camera feeds, and review recorded clips from any incident. Full control of your site security, wherever you are.

On another job, in a meeting, or off site entirely, you always know exactly what is happening. No more being the last person to find out something went wrong.

Deploy in minutes. Protect any site. Anywhere.

The Sirix Autonomous Security Box is a self-contained, AI-powered security unit that goes where traditional security cannot. No trenching, no network cabling, no Wi-Fi. Just full perimeter protection from the moment it is on site.

Connects to a power source by default, and can be configured for solar on sites where power is not yet available.

Rent or buy, and the maths is simple. An Autonomous Security Box rents for $850 per month or costs about $4,200 to own, so buying pays for itself at roughly five months. Short builds and phased work rent. Anything running past five months is cheaper to own.

Detection range

Live within

Built around your timeline

40%+ less than an overnight guard post.

A single overnight guard post on a construction site runs roughly $8,500 to $12,700 per month. That is one guard, one zone, one shift, at typical North American agency bill rates of $28 to $35 per hour for a night shift of 10 to 12 hours, seven nights a week. Sirix covers your entire site around the clock, with AI detection and live operators working together, for a fraction of that.

The 40% figure is deliberately conservative. It holds even when cameras, connectivity, and Autonomous Security Box units are counted on the Sirix side and only base rates are counted on the guard side. Most sites land well past it.

Pricing

What does construction site security cost?

Most construction sites run between $200 and $1,800 per month. What you pay depends on how many Autonomous Security Boxes and cameras your site needs, and how many hours you want covered.

A single overnight guard post

$8,500 to $12,700

per month

One guard, one zone, one shift. Based on North American agency bill rates of $28 to $35 per hour for a 10 to 12 hour night, seven nights a week.

Sirix on the same site

$200 to $1,800

per month

Your entire site, around the clock, with AI detection and live operators working together. Every event verified by a person before anyone is dispatched.

What you are paying for

Monitoring is charged per device per month. Outdoor cameras running analytics, radar, fire detection, and voice intervention each carry their own rate, so you pay for the coverage your site actually needs and nothing else.

Rent or buy the box

An Autonomous Security Box typically rents from around $850 per month, and ownership generally falls in the range of $4,000 to $4,500 depending on configuration, so on most sites buying starts to pay off somewhere around the five month mark. Short builds and phased work usually rent. Longer programs tend to work out lower over time when owned.

What moves the price

Site size and number of access points, how many boxes and cameras you need, the analytics each device runs, whether you want daytime coverage as well as nights, and your site’s response procedures.

Sites that already have cameras on the perimeter start lower. Large multi-zone sites with several boxes run higher.

Pricing is quoted in the currency of the site’s country.

Prices shown are general information only. Actual pricing varies based on site conditions, equipment, coverage hours, and service configuration, and is not guaranteed.

Why construction sites choose Sirix.

From the first crew on site to the last camera offline, Sirix is built around how construction security actually works.

24/7 live operators. Not just software

Real security professionals monitor, verify, and respond around the clock, following your site SOPs, every time, without exception.

AI built for construction environments

20+ AI detection models trained for real jobsite conditions, from crane climbing and loitering to PPE violations and perimeter breaches.

Works with your existing cameras

Sirix integrates with most major camera systems and over 500 security partners. No rip and replace, just enhanced protection layered on your current setup.

Deploy anywhere, move as you build

The Autonomous Security Box requires no wiring, no Wi-Fi, and no trades. It is operational in minutes and relocates as your project evolves, phase to phase.

Verified alarms. Zero unnecessary dispatches

Every alert is assessed by a live operator before any action is taken. No false alarm fines, no wasted emergency response, no liability from unverified escalations.

Full documentation for every incident

Timestamped footage, verified response logs, and exportable incident reports: everything insurers, lawyers, and project owners need, already there when you need it.

The command center

Who is actually watching your site

Every Sirix alert is handled by a trained human operator, not an automated system. Sirix runs two geographically separate command centers, each able to carry the full monitoring load on its own. If one goes offline, the other picks it up without interruption. Your site never goes dark.

operators minimum, at any hour

Never fewer than eleven trained operators on the floor, around the clock. A further three are dedicated to continuous monitoring, watching high-risk sites live rather than waiting for an AI trigger.

3 months

before an operator works alone

Every operator is screened personally by Yannick Perreault, our operations coordinator, passes a criminal background check, and must be bilingual to be hired at all. Training runs three months before an operator is trusted with a post on their own.

Every shift

runs with a supervisor on the floor

No shift runs unsupervised. A supervisor is present at all times to make sure procedures are followed exactly.

centers, full
redundancy

Either command center can carry the entire monitoring load. An outage at one does not interrupt coverage at your site.

Building site security for every project type and phase.

No two construction projects have identical security needs. Site layout, phase of construction, number of access points, material value, and location all shape the right security strategy. Sirix delivers tailored solutions for every type of build.

Commercial and office construction

Large footprint commercial builds with multiple contractor teams, high-value materials, and frequent deliveries. LPR and remote access control ensure only authorized personnel and vehicles are on site, with a verified log of every entry.

Industrial and manufacturing construction

Heavy equipment projects with high-value machinery, sensitive infrastructure, and strict access protocols. Thermal imaging and long-range AI cover wide perimeters across large sites, day or night, in any condition.

Residential and condo developments

Multi-unit, townhome, and mid-rise residential projects need perimeter protection, visitor access control, and overnight theft prevention during framing and finishing, when lumber, copper, and appliances are most vulnerable.

High-rise and skyscraper projects

Vertical construction with crane equipment, multiple floor access points, and high theft risk at materials staging areas. Crane climbing detection AI stops unauthorized access to elevated structures before it becomes a safety or liability incident.

Infrastructure, roads and civil engineering

Linear or distributed sites covering large distances where a single camera system cannot cover the full perimeter. ASB units with LTE connectivity provide relocatable coverage that moves with the project as construction progresses.

Renovation and demolition sites

Short duration, high-risk sites where exposed materials, salvageable metal, and unsecured perimeters attract opportunistic theft. ASB units are live within 48 hours of setup, with no long-term installation required.

Equipment and material storage yards

Off-site staging areas and equipment yards storing copper, lumber, generators, and heavy machinery overnight. Remote monitoring provides full visibility without an on-site guard presence, with zero network cabling or infrastructure.

Multi-phase and long duration builds

Projects spanning one to three or more years with evolving layouts and shifting security needs. ASB units relocate with the build, from ground prep through topping out, maintaining coverage at every phase without reinstallation costs.

Construction site security compliance, simplified.

In many jurisdictions, construction site security is not just good practice, it is a legal obligation. Sirix supports compliance with the major regulatory frameworks governing construction site safety and security across North America.

What does OSHA require for construction site video documentation?

OSHA does not require video surveillance on construction sites. 29 CFR 1926.20(b)(2) requires employers to run safety programs that include frequent and regular inspections of job sites, materials, and equipment, and 29 CFR 1904 requires recording and reporting of work-related injuries and illnesses. Video documentation of safety protocols and timestamped incident records support both obligations without satisfying either on its own.

Do some US states have stricter construction safety rules than federal OSHA?

Yes. Some states operate their own OSHA-approved plans with standards that can exceed the federal baseline. California’s Cal/OSHA, governed by Title 8 of the California Code of Regulations, is generally the most stringent, with additional training, hazard communication, and enforcement requirements for construction. States without an approved plan, including Texas, fall under federal OSHA directly. Confirm which framework applies to your site.

What are the rules for notifying construction workers about site cameras in the United States?

There is no single federal rule. The Electronic Communications Privacy Act and the Stored Communications Act permit monitoring for legitimate business purposes while restricting interception of private communications. Some states, including New York, require notice to employees. In California, the Consumer Privacy Act applies data minimization, so monitoring must be necessary and proportionate. Clear written notice of what is monitored and why is the common baseline.

What does Ontario's Occupational Health and Safety Act require on construction projects?

The OHSA and Ontario Regulation 213/91 govern construction projects. A Notice of Project is required where labour and material costs exceed $50,000 or the work meets other thresholds in section 6. Constructors must establish and post written emergency procedures, ensure every worker has ready access to two-way communication in an emergency, and keep required records for at least one year after the project finishes.

What does WorkSafeBC require after a construction site incident?

British Columbia’s Workers Compensation Act and OHS Regulation set two separate obligations. Employers file WorkSafeBC Form 7 within 72 hours where a worker missed time or needed treatment beyond first aid, with immediate phone notification for serious incidents. A preliminary investigation report is due within 48 hours and a full report within 30 days. Investigation records are generally kept at least three years.

What does Alberta OHS require on a construction site?

Alberta’s framework has three layers: the OHS Act, the OHS Regulation, and the OHS Code. A prime contractor is required on every construction site with two or more employers. Serious incidents, including fatalities, hospital admissions, and the collapse of a crane or of any component of a building or structure, must be reported to OHS as soon as possible. The scene must not be disturbed.

What does Quebec CNESST require after a workplace incident?

Under Quebec’s Act respecting occupational health and safety, the employer must inform the CNESST as quickly as possible, and within 24 hours, of incidents meeting the thresholds in section 62. The scene must be preserved until the CNESST authorizes changes. Employers also carry duties covering workers’ psychological integrity alongside physical safety, and certain OHS records carry retention periods of up to five years.

What privacy rules apply to video monitoring of construction workers in Canada?

It depends on where the site is. Only Alberta, British Columbia, and Quebec have private-sector privacy laws deemed substantially similar to PIPEDA, which otherwise governs federally regulated employers. Quebec’s Law 25 requires monitoring to have a legitimate purpose, be proportionate and minimally intrusive, and requires workers to be informed of the type, purpose, and timing of monitoring. Ontario employers with 25 or more employees must maintain a written electronic monitoring policy.

What do builders risk insurers require for construction site security?

Requirements are set by the carrier and the policy, not by regulation. Builders risk and course of construction policies commonly ask about perimeter control, lighting, access control, and whether the site is monitored, and monitored sites can qualify for reduced premiums. Ask your broker what your specific policy requires before you finalise your site security plan.

FAQs

Everything you need to know about construction site security.

The most common questions from project managers, security managers, and developers before they partner with Sirix.

How does Sirix protect construction sites after hours?

Sirix combines AI video detection with live operators who watch construction sites 24/7 from a monitored command centre. 20+ AI detection models flag activity on your perimeter, a trained operator verifies it on live video within seconds, and that operator intervenes by voice through on-site speakers, activates sirens and strobes, or dispatches police, following your site’s procedures. Every event is recorded with timestamped video.

What is the difference between remote video monitoring and security guards?

A security guard covers one zone on one shift and costs roughly $8,500 to $12,700 per month at typical North American agency rates. Remote video monitoring covers your entire site around the clock for $200 to $1,800 per month, with AI detection and a live operator who verifies every event before anyone is dispatched. Guards still do things monitoring cannot, such as physically escorting someone off site.

Can construction site security work on temporary or remote sites?

Yes. The Sirix Autonomous Security Box is a self-contained unit with a 295 ft (90 m) detection range that needs no network cabling, no Wi-Fi, and no site infrastructure. It mounts on a pole or wall, runs on its own LTE connection, and relocates in minutes as your project moves from foundation work to finishing. Rent it for $850 per month or buy it outright.

How much does construction site security cost?

Most construction sites run between $200 and $1,800 per month. Monitoring is charged per device per month, so what you pay depends on how many cameras and Autonomous Security Boxes your site needs and how many hours you want covered. Sites that already have perimeter cameras start lower. That compares with roughly $8,500 to $12,700 per month for a single overnight guard post.

What is the ROI of remote video monitoring for construction sites?

Remote video monitoring costs at least 40% less than an overnight guard post, and usually far more than that. The larger return is avoided loss: a single day of project delay costs between $1,000 and $10,000+ depending on project size, fewer than 25% of stolen construction machines are ever recovered, and every Sirix event is verified by a person, so there are no false alarm dispatch fines.

Does construction site monitoring include worker safety and PPE compliance?

Yes. Sirix runs 20+ AI detection models that include PPE compliance, fall hazards, and unsafe behaviour alongside intrusion detection. Operators also respond to lone worker and man down alarms, following your emergency procedures and coordinating help without delay. Video documentation of safety protocols and timestamped incident reporting support OSHA and provincial recordkeeping obligations.

Can Sirix monitor multiple construction sites from one platform?

Yes. Sirix monitors 25,000+ devices across 230+ cities in Canada and the United States, and multi-site contractors manage every project from one account. You can arm or disarm any site remotely, view live camera feeds, and review recorded clips from any incident on your phone, tablet, or laptop. Each site keeps its own procedures and response rules.

How fast can construction site security be installed?

A Sirix site is live within 48 hours of setup. Autonomous Security Boxes mount on poles or walls with no trenching, no network cabling, and no trades, or Sirix connects to cameras you already have across 500+ camera and device integrations. Configuration is handled remotely, so there is no downtime on your build while the system comes online.

How does Sirix handle false alarms on construction sites?

AI filtering removes 95% of the noise before a human ever sees it, and every remaining event is verified by a trained operator on live video before any action is taken. Nothing is escalated automatically. That means no unnecessary police dispatches, no false alarm fines, and no penalty fees from repeat unverified calls.

What happens when an intruder is detected on my construction site?

AI flags the activity and a trained operator verifies it on live video within seconds. The operator then follows your site’s procedures: a live voice warning through on-site speakers, sirens and strobes activated across the perimeter, a call to your team, or police dispatch. In a reviewed sample of 200 verified intrusions, 199 were resolved without police dispatch.

Does construction site security work without power or internet?

The Autonomous Security Box needs no internet connection of its own: it runs on LTE with data included, so no Wi-Fi, no network cabling, and no site infrastructure are required. Power works differently. The box connects to a power source by default, and on sites where power is not yet available, external battery and solar options allow fully off-grid deployment.

What are the OSHA video documentation requirements for construction sites?

OSHA does not require video surveillance on construction sites, but 29 CFR 1926 does require employers to record and report workplace incidents. Video documentation of safety protocols, PPE compliance monitoring, and timestamped incident reporting support those recordkeeping obligations and OSHA investigations. Sirix also supports Ontario’s Occupational Health and Safety Act, WorkSafeBC, Alberta OHS, and Quebec CNESST.

How long is construction site footage kept?

Retention is set per site and typically runs from three months to one year, depending on what your project, your insurer, and your jurisdiction require. Sirix follows the retention and privacy requirements that apply in the region where each site operates. Your specific retention period, storage location, and handover at project close are confirmed in your service agreement.

Can Sirix monitor a construction site that is shut down or between phases?

Yes. Dormant sites are among the most exposed, because equipment and materials stay on site while nobody does. Sirix monitors sites through winter shutdowns, permit delays, and gaps between phases, with the same AI detection, live operator verification, and voice intervention used on active builds. Coverage hours can be adjusted as the site’s activity changes.
