Decision Guide: 24-Hour Warehouse Security for Surrey & Fraser Valley Distribution Centres

A warehouse can look quiet from the street and still involve employees, drivers, contractors, gates, loading docks, trailers, restricted rooms, and several access schedules. That is why “one security guard” is not a complete warehouse security plan.

Surrey has eight recognized business parks, including Campbell Heights, Port Kells, Newton, and Cloverdale. The City of Surrey’s industrial-land information shows the scale of this environment. Warehouses across Langley, Abbotsford, Chilliwack, and the Fraser Valley also vary greatly.

This guide compares 24-hour guards, overnight coverage, gatehouse posts, mobile patrol, alarm response, and blended security. It also explains coverage hours, simultaneous posts, relief, handovers, and reporting.

This article is general planning information, not legal advice. Review employment, privacy, safety, insurance, and security procedures for the workplace.

Quick Answer

Not every warehouse needs a security guard on site 24 hours a day. Continuous coverage may fit a facility with round-the-clock operations, frequent access, separated critical zones, sensitive inventory, or immediate on-site response requirements.

A warehouse that closes overnight and has effective physical and electronic controls may only need mobile patrol, alarm response, overnight guarding, or a blended plan. The right decision depends on what must be controlled, when and where duties occur, and what must be documented.

Why Warehouse Security Planning Is Different

Warehouse security may involve people, vehicles, credentials, docks, trailers, gates, cameras, alarms, and time-sensitive deliveries. Planning must account for how those elements interact, especially during shift changes, breaks, late deliveries, and system failures.

Before asking how many guards are needed, ask:

• Which activities require continuous control?
• Which areas can be checked periodically?
• Which duties happen at the same time?
• Can one guard leave a fixed post to complete a patrol?
• What should happen during breaks or shift handovers?
• What requires an immediate call, and what records does management need?

Map the operation before choosing a staffing number. Zentra’s commercial property security walkthrough offers a broader starting point for doors, gates, lighting, alarms, parking, and after-hours access.

Does Every Warehouse Need 24-Hour Security?

No. Continuous coverage is one option, not a universal requirement.

Evaluate it when:

• the warehouse operates continuously
• trucks, drivers, contractors, or employees arrive overnight
• a gate or shipping entrance must remain controlled
• the site has a large yard or separated critical areas
• valuable, sensitive, or customer-owned inventory is present
• deliveries or trailer movements require ongoing verification
• incidents, access exceptions, or an external requirement support it
• one duty cannot be paused while another area is checked

A lower-intensity model may fit when:

• it closes predictably and has few access points
• physical security controls are in good condition
• alarms and cameras cover priority areas with little after-hours entry
• the main need is lock-up verification or exterior observation
• a trained responder can attend after an alarm
• the site can tolerate gaps between patrol visits

The decision should reflect the real property—not a generic warehouse label.

Warehouse Security Zone Walkthrough

Review the building as operational zones. Separated zones may need different controls or simultaneous duties.

Warehouse zone | Review | Possible approach | Useful record

Vehicle gate | Authorization, traffic flow, gate condition | Fixed post during active periods | Arrivals, departures, exceptions

Employee entrance | Cards, tailgating, shift-change volume | Access system plus targeted presence | Access and door exceptions

Visitor entrance | Approval, sign-in, restricted areas | Reception or guard procedure | Permitted visitor details

Shipping and receiving | Delivery schedule and release authority | Fixed or peak-period coverage | Unscheduled or refused access

Loading docks | Open doors, trailer movement, blind spots | Dock procedure plus patrol | Door, lighting, camera issues

Trailer yard | Fence lines and unauthorized movement | Foot or vehicle patrol | Fence, gate, agreed unit exceptions

Parking | Lighting, pedestrian routes, vehicles | Patrol or targeted presence | Visible concerns

Restricted inventory | Authorization, doors, cages, key control | Access control and checks | Access or lock exceptions

Utility areas and exits | Restricted access, doors, obstructions | Scheduled checks | Conditions needing escalation

Duties must be site-specific and should not turn a guard into a shipping clerk, warehouse worker, maintenance technician, safety manager, or police officer.

24-Hour Guard, Overnight Guard, Gatehouse, Patrol, or Alarm Response?

Different services solve different problems.

An on-site guard provides continuous presence during the assigned shift. A gatehouse post focuses on access and vehicle movement. Mobile patrol provides intermittent visits. Alarm response begins after a notification. Cameras and access systems support detection and records but do not provide a physical response.

For a broader comparison, read Zentra’s mobile patrol vs on-site security decision guide.

Buyer Decision Table

Coverage model | Best suited for | Main limitation

24-hour on-site guard | Facilities with continuous access, shipping, gate control, or response duties | One guard cannot cover multiple separated critical posts simultaneously

Overnight on-site guard | Warehouses where the main security requirements occur after business hours | No dedicated guard is present during uncovered daytime hours

Gatehouse guard | Sites requiring control of vehicles, drivers, visitors, or deliveries | Does not automatically cover docks, yards, parking areas, or warehouse interiors

Mobile patrol | Warehouses needing scheduled perimeter, parking, lock-up, or exterior checks | Conditions between patrol visits may not be observed immediately

Alarm response | Sites requiring attendance after a monitored alarm or verified notification | Reactive service without continuous on-site observation

Blended coverage | Facilities where security needs change by time, activity, or property zone | Duties, handovers, escalation procedures, and responsibilities must be clearly defined

What to Confirm Before Choosing Coverage

• Operating, delivery, and dispatch hours
• Number of entrances, gates, docks, yards, and detached buildings
• Duties that must be performed simultaneously
• Posts that cannot be left unattended
• Travel time between critical areas
• Meal and washroom relief requirements
• Alarm, camera, access-control, and keyholder arrangements
• Reporting and incident-escalation expectations

This comparison is a starting point. The final security coverage model should be based on a site assessment and a clearly written scope of work.

How Many Security Guard Posts Does a Warehouse Need?

There is no reliable universal guard-to-square-foot, guard-to-dock, guard-to-employee, or guard-to-acre ratio. Identify duties that must occur at the same time instead.

One guard cannot continuously control a busy vehicle gate while also patrolling the opposite end of the property. The same issue appears when one person must verify deliveries, watch a detached yard, and respond to alarms without leaving a critical post.

Consider separate or overlapping coverage when:

• two critical entrances operate simultaneously
• a fixed post cannot be left
• the patrol route takes the guard out of view or communication
• travel between zones is meaningful
• shift changes or arrivals create a traffic peak
• breaks require the post to remain occupied

The question is whether the required duty remains covered while the guard is away.

The 168-Hour Weekly Coverage Calculation

One continuously staffed post requires:

24 hours × 7 days = 168 coverage hours per week

That means:

Continuously staffed posts | Weekly coverage hours

1 | 168

2 | 336

3 | 504

Coverage hours are not employee headcount. Staffing also depends on shift length, overtime, days off, relief, absences, training, supervision, and qualifications. Handover or peak-period overlap may add hours without adding a permanent post.

For budget planning, a simple starting formula is:

Number of posts × required service hours × approved service rate

The final proposal may also reflect supervision, short-notice deployment, statutory holidays, specialized duties, travel, equipment, reporting, and relief requirements.

Shift Structure, Break Relief, and Handovers

A continuous post requires a continuous plan. British Columbia’s Employment Standards Act meal-break provisions require a meal break after no more than five consecutive hours of work. If an employee must work or remain available during it, that time counts as time worked.

The operational scope should therefore state:

• whether a fixed post may ever be left
• who provides washroom and meal relief
• how temporary absences are communicated
• whether another trained guard can take over the post
• what must be recorded during the relief period
• which duties pause and which must continue
• how emergencies are handled during a handover

For a guard assigned to work alone or in isolation, WorkSafeBC’s OHS Regulation requires written well-being checks, predetermined intervals, a missed-contact response, records, and an end-of-shift check. The procedure should reflect the assignment and hazards.

A shift handover should cover:

• unresolved incidents or access exceptions
• keys, cards, radios, phones, and site equipment
• open gates, doors, trailers, or loading bays requiring attention
• expected visitors, drivers, vendors, or contractors
• alarm, camera, lighting, or access-control issues
• temporary instructions and management notifications
• safety concerns or restricted areas
• incomplete reports

What Warehouse Post Orders Should Include

Post orders turn a general request into a defined assignment. Include:

1. Site contacts and the escalation chain.

2. Authorized employee, visitor, contractor, and driver access rules.

3. Gate-opening, closing, and lock procedures.

4. Delivery verification and unscheduled-arrival procedures.

5. Patrol areas, checkpoints, frequency, and access limitations.

6. Restricted areas and duties requiring manager authorization.

7. Key, card, code, and equipment control.

8. Alarm and camera responsibilities within the assigned scope.

9. Fire, medical, intrusion, safety, and utility escalation.

10. Shift handover and relief procedures.

11. Daily, incident, and exception-report requirements.

12. Privacy restrictions and duties the guard cannot perform.

Post orders should be reviewed whenever operating hours, access points, tenants, inventory, construction, delivery patterns, technology, or management contacts change.

Access, Delivery, and Loading-Dock Procedures

The provider and warehouse operator should agree on what “verify access” means. An authorized process may require a guard to compare an arrival with an approved list, contact a representative, record permitted details, issue a credential, direct the person to a waiting area, or refuse entry and escalate.

The procedure should answer:

• Who can authorize an unscheduled delivery?
• What information may be collected?
• Which entrances may drivers or visitors use?
• Who releases a vehicle, trailer, or shipment?
• What happens when documents do not match?
• May the guard inspect a seal or vehicle, and under whose written authority?
• Which issue requires management, police, fire, or medical assistance?

A guard should not approve shipments, operate warehouse equipment, perform unrelated inspections, or make commercial decisions for the client.

Privacy, Cameras, and Employee Searches

Warehouse procedures may involve names, images, access records, vehicle details, visitor logs, and video. British Columbia’s Personal Information Protection Act limits how private organizations handle personal information. The BC privacy commissioner also provides private-sector guidance.

As a practical starting point:

• collect only information needed for a defined and reasonable purpose
• provide required notice
• limit access to authorized people
• set an appropriate retention period
• protect records against unauthorized use or disclosure
• review camera placement and monitoring practices
• control who may retrieve or share records

A private security guard does not automatically have unrestricted authority to search an employee, bag, locker, or vehicle; seize personal property; detain a person; or use force.

Any search or inspection process depends on applicable law, consent, policy, contracts, privacy, training, and the circumstances. Review and write the process before assigning it to a guard.

Reporting & Documentation

Professional warehouse security should leave useful records—not only “everything appeared normal.” Reporting may include:

• shift start and end
• guard post and patrol activity
• access, visitor, contractor, or driver records where authorized
• gate, door, lock, fence, and lighting observations
• loading-dock or trailer-yard exceptions
• key and access-card transfers
• alarm or camera issues
• time-stamped photographs where appropriate and authorized
• incident chronology
• notifications and escalation steps
• unresolved items for the next shift
• management follow-up

Separate routine observations from incidents and urgent matters. State what the guard observed, what someone else reported, what action followed, and who was notified. Because reports may be sensitive, define recipients, storage, access, and retention. See what a property security check report should include.

How Technology and Guards Work Together

Cameras, alarms, access control, intercoms, gates, lighting, and patrol checkpoints can help when each has a defined purpose.

Technology may:

• detect movement or a forced door
• record an event
• restrict credentials
• create an access history
• alert a monitoring station
• help a responder focus on a priority area

A trained person may:

• verify what is visible on site
• communicate with drivers, staff, or management
• follow an escalation procedure
• check an authorized area
• preserve observations
• create a chronological report

Technology may reduce physical coverage in some areas, but it does not automatically replace access control, response, relief, or judgment. A guard also cannot compensate for broken gates, poor lighting, blind cameras, outdated lists, or unclear instructions.

What Affects Warehouse Security Cost?

Cost depends on the scope, not only building size. Factors include:

• number of simultaneous posts
• total weekly coverage hours
• operating and delivery schedule
• fixed-post and patrol responsibilities
• size and separation of buildings, docks, yards, and gates
• relief and handover requirements
• peak-period overlap
• qualifications and site training
• reporting detail
• supervisor involvement
• technology or equipment requirements
• short-notice or temporary deployment
• statutory holidays
• contract length
• travel or remote-site conditions
• mobile patrol or alarm-response layers

A useful proposal explains the schedule, duties, reports, escalation, and assumptions. A low hourly number means little if posts and responsibilities are unclear.

Zentra Field Note: Coverage Gaps Often Appear During Transitions

Coverage can become unclear during shift changes, driver arrivals, breaks, gate movements, late deliveries, and handovers. One person may be expected to perform several duties, or an unresolved issue may pass to the next shift.

Before adding more hours, review these transitions. Short overlap, clearer post orders, proper relief, or a better handover may solve a specific gap more effectively than uniform staffing all day.

How Zentra Handles Warehouse Coverage Planning

Zentra starts with the operation rather than automatically recommending the largest package:

1. Understand operations: Review hours, staff, drivers, contractors, deliveries, and access patterns.

2. Walk the property: Identify gates, entrances, docks, yards, parking, restricted rooms, and separated zones.

3. Define coverage: Decide which duties need fixed posts, patrols, relief, or peak-period overlap.

4. Prepare instructions: Establish post orders, contacts, authorization limits, and escalation steps.

5. Set reporting expectations: Confirm what gets recorded, who receives reports, and what requires an immediate call.

6. Review and adjust: Reassess when the operation, layout, incident pattern, or technology changes.

Zentra’s security guard hiring checklist explains how to compare licensing, insurance, duties, supervision, reporting, and contract clarity.

Frequently Asked Questions

Does every warehouse need 24-hour security?

No. It may fit continuous operations, frequent access, separated zones, sensitive inventory, or immediate-response needs. A quieter site may suit overnight guards, patrol, alarm response, or a blended model.

How many guards does a warehouse need?

There is no universal number. Count the duties and critical areas that must remain covered simultaneously. Separate gates, yards, buildings, and fixed-post relief may require overlap.

How many hours are required for one 24-hour security post?

One continuous post requires 168 weekly coverage hours: 24 × 7. That is not employee headcount.

Can one guard cover both the gate and the warehouse?

Possibly, if activity is limited, the route is short, and the post may be left. Continuous gate control or separated critical areas may require additional coverage.

Can mobile patrol replace an on-site warehouse guard?

Sometimes. Patrol may suit a closed warehouse needing intermittent checks and alarm attendance. It does not provide continuous presence at an active gate or fixed post.

What should a warehouse security guard record?

Reports may include activity, access exceptions, patrols, gate or door conditions, incidents, notifications, authorized photographs, and handover items.

Should a security guard check delivery drivers?

A guard may verify them under a lawful written process with authorization and escalation steps. The guard should not make shipping decisions.

Can a security guard search an employee’s bag or vehicle?

There is no automatic unrestricted authority. Any process depends on law, consent, policy, contract, privacy, training, authorization, and circumstances. Obtain appropriate guidance first.

How should breaks be covered at a fixed post?

State whether the post may be left, who provides relief, what remains active, and how the change is recorded. Follow current employment and safety requirements.

Do cameras eliminate the need for guards?

No. Cameras can detect and record; a guard can verify, communicate, respond within scope, and document. Some sites still need a person at a critical post.

What affects warehouse security pricing?

Key factors are posts, hours, layout, shifts, relief, patrols, traffic peaks, qualifications, supervision, reporting, technology, holidays, travel, and term.

Does Zentra provide warehouse security in Surrey and the Fraser Valley?

Yes, subject to service, schedule, location, and staffing availability.

Choose Coverage Based on the Operation

Warehouse security should follow real operating needs: map the zones, identify simultaneous duties, calculate hours, plan relief and handovers, and define access, escalation, reporting, and privacy limits.
