Trusted Security Systems for Multi-Tenant Office Buildings
Office Security System
Shared lobbies, elevator access and after-hours cleaning crews carry risks a single-tenant building doesn't, JMG builds access control, video and monitoring around how a multi-tenant office actually operates.
Office Security Starts With Employee Trust
Every figure below holds up to a check. No padded uptime claims, no borrowed response times, no credentials we don't actually carry.

WHERE BUILDING SECURITY BREAKS DOWN
Four Situations Property Managers Call Us About
Each one reflects what actually happens inside a multi-tenant office building, not a generic scenario.
01
Cross-Floor Credential Bleed
A tenant's badge was provisioned for their suite. It also happens to open the floor above, and nobody flagged it during setup.
FLOOR-LEVEL PERMISSIONS
02
Unlogged Elevator Lobby Access
A visitor rides up after the lobby desk closes for the night. Whether that elevator stop got logged anywhere depends on who you ask.
ELEVATOR ACCESS
03
Active Credentials After Offboarding
An employee left the tenant company two months ago. Their badge still opens the front door at 6 a.m. on a Saturday.
CREDENTIAL DEACTIVATION
04
Unmanaged After-Hours Cleaning Access
The cleaning crew has a master schedule for the whole building. Which crew member badged into which suite, and when, isn't something anyone can pull up.
VENDOR ACCESS LOGS
Three Systems, One Office Standard
Office security has three jobs: control who's in the building, know who visited and when, and keep every floor covered without slowing employees down.
Connect With A Security Advisor01
Access & Visitor Management
Badge readers, video, and visitor check-in run as one system instead of a lobby sign-in sheet and a separate keycard vendor. Entry points restrict to authorized staff, visitors are logged automatically, and after-hours alarms reach a live dispatcher instead of just sounding a siren.
02
Video & Incident Response
Lobby, parking, and common-area cameras cover the spaces employees actually pass through, with footage stored and searchable when HR or facilities needs to review an incident.
03
Fire & Life Safety
Detection and notification cover every floor, with inspection records kept as documentation so a building audit is a formality, not a scramble.
CASE STUDY · HARLOW & VANCE LAW GROUP
Two Floors Became Six, On One Standard.
One job, in the order it happened: what was there, what we designed, what changed, and what is in place now.
SITUATION
A client since 2016, expanding by lease from two floors to six, each addition arriving with its own keycard reader and its own visitor log.
APPROACH
Account manager Sarah Nolan and systems tech Ben Whitfield brought every floor onto one access and video standard as each expansion opened.
OUTCOME
6
Floors on one system and one badge, up from the original two.
ONGOING
Office Manager Priya Anand records her own account of the rollout in the client's video.
YOUR BUILDING'S EXISTING SYSTEM
Preserving Working Infrastructure
Replacing every system is the easiest proposal to write, and rarely what an office building needs.
USUALLY STAYS
Retained System Components
01
Cabling and conduit that still meets code
02
Cameras and turnstile readers within their service life
03
Panels a manufacturer still supports
04
Credentials your tenants already carry
USUALLY REPLACED
Justified Equipment Replacement
01
Equipment a manufacturer has stopped supporting
02
Elevator access hardware with no after-hours log
03
Communication paths with no monitored backup
04
Readers that can't restrict access by floor as they stand
Which list a given device lands on is decided by the walkthrough at your building, not a catalogue. You receive the reasoning in writing before anything is ordered, and the assessment is free whether or not you go ahead.

Designing In Southern California
See the Lobby First
Access-Verified Monitoring
When a door alert and relevant video are connected, operators can use available footage to better understand whether activity at the lobby or elevator bank appears routine, a tenant working late, or an unauthorized attempt, before dispatching a response.

WHY JMG
Five Things An Office Building Can't Buy From A Manufacturer
What a property manager gets from a security partner instead of a single vendor.
01
OUR OWN NETWORK
Private Alarm Network
A private, self-healing radio mesh, FCC and UL licensed to JMG. If a lobby or elevator alarm path drops, the event is raised, not missed after the front desk closes.
02
BY DESIGN
Vendor-Neutral Design
We do not manufacture anything. We design with 19+ manufacturers, so the recommendation fits your building's tenant mix, not a sales quota.
03
NOT SUBCONTRACTORS
In-House Field Teams
JMG technicians work out of every Southern California region. Same credentialed people, same standard, same paperwork, every time they're on-site at your property.
04
ONE PLACE TO WORK FROM
Unified Security Platform
Lobbies, elevators, cameras and tenant credentials are reached from the same place with the same permissions, not five apps across five tenants.
05
HOWEVER MANY SITES
Standardized Multi-Site Security
A new building is built to the standard your other properties already run on, so on-site staff don't relearn anything.
