Physical Integration
Design and installation of the physical systems a building runs on: access control, video surveillance, visitor management, environmental detection. Everything from the unseen infrastructure to the functional technologies that keep a space safe and secure.
Access Control
Commercial access control systems decide who can enter your buildings, and when. 4S Security designs, installs, and services cloud-based and on-premise access control for commercial real estate, cultural institutions, multifamily properties, and corporate offices nationwide.
Person and Identity Management
Organize your workforce by unique identifiers and credentials. Add or remove users in minutes, keep a living record of who can access each space, and pull entry history whenever you need it.
Credential Management
Centralize credentials for tenants, employees, and guests. Mobile credentials, key cards, and fobs stay current across every door, so secure areas and sensitive data stay restricted to authorized people.
Multi-Site Administration
Run every property from one platform. Campuses, multi-floor offices, and annex buildings share a single access policy, so your team manages one system instead of five.
Access Control — FAQ
How much does a commercial access control system cost?
Pricing depends on door count, credential type, and cloud vs. on-premise architecture. 4S provides fixed-fee proposals after a site walk, with no consumption metering and no surprise line items.
Should we choose cloud-based or on-premise access control?
Cloud fits multi-site portfolios that want centralized management without server infrastructure. On-premise fits organizations with strict data residency requirements. 4S designs both and recommends based on your IT policy.
Can you integrate with our existing readers and credentials?
In most cases, yes. 4S works with Mercury, HID, and most major panel hardware, and can often reuse existing readers and wiring to control cost.
How long does installation take?
Timelines depend on door count and site readiness. Every 4S installation runs under dedicated project management, delivered by technicians who average 11 years with the company.
Do you service systems you didn't install?
Yes. 4S takes over service and monitoring for existing access control deployments, including buildings managed by other integrators.
Biometrics
Biometric access control uses unique physical traits, fingerprints, faces, and irises, to verify identity at the door. 4S Security designs, installs, and services biometric readers for commercial real estate, cultural institutions, multifamily properties, and corporate offices where credentials alone aren't enough.
Fingerprint, Face & Iris Recognition
Match the right modality to each door. Fingerprint readers handle high-traffic entries, facial recognition supports touchless access at a distance, and iris scanners secure the most sensitive areas where false accepts carry real cost.
Multi-Factor & Frictionless Access
Layer biometrics with cards, mobile credentials, or PINs for higher-assurance doors, or run biometric-only at entries where speed matters. Touchless facial recognition lets authorized staff pass without breaking stride.
Privacy & Compliance by Design
Biometric templates are encrypted at rest and in transit, never stored as raw images, and scoped to your data residency and policy. 4S configures retention, consent, and audit logging to meet your compliance requirements.
Biometrics — FAQ
How much does a biometric access control system cost?
Pricing depends on reader count, modality (fingerprint, face, or iris), and integration with your existing access platform. 4S provides fixed-fee proposals after a site walk, with no consumption metering and no surprise line items.
Which biometric modality should we choose?
Fingerprint readers fit high-traffic, budget-conscious doors. Facial recognition adds touchless convenience and works at a distance. Iris scanners suit the most sensitive areas where accuracy is paramount. 4S recommends based on your doors, traffic, and risk.
Can biometrics integrate with our existing access control?
Yes. Biometric readers connect to most major access control platforms, including Mercury and HID-based systems, often using your existing wiring and panels. Biometrics can replace or supplement cards and mobile credentials.
How is biometric data protected?
Templates are encrypted and stored as mathematical representations, never as raw fingerprints or face images. 4S configures retention, consent flows, and audit logging to meet your compliance and data residency requirements.
What happens if a reader goes down?
Every 4S biometric deployment includes a defined fallback, typically a secondary credential or manned entry, so a hardware issue never locks out authorized staff. 24/7 monitoring flags reader outages the moment they occur.
Video Surveillance
Commercial video surveillance systems give you eyes on every critical area of your buildings, live and on record. 4S Security designs, installs, and services camera systems with cloud and on-premise storage, intelligent analytics, and 24/7 monitoring for commercial real estate, cultural institutions, multifamily properties, and corporate offices nationwide.
Video Analytics & Operational Insights
Move beyond recorded footage. Intelligent analytics detect unusual activity, count occupancy, and flag incidents as they happen, turning your cameras into a source of real-time operational intelligence.
Cloud-Connected Surveillance
Access every camera from any device, anywhere. Cloud storage removes the cost and maintenance of on-site servers while keeping footage secure, searchable, and retained to your policy.
Design, Visibility & 24/7 Support
Our design team plans every angle and viewpoint for complete coverage, then matches resolution and hardware to each location. After installation, 24/7 monitoring watches your cameras and alerts you to incidents in real time.
Video Surveillance — FAQ
How much does a commercial video surveillance system cost?
Pricing depends on camera count, resolution, analytics licensing, and cloud vs. on-premise storage. 4S provides fixed-fee proposals after a site walk, with no consumption metering and no surprise line items.
Cloud vs. on-premise video storage: which is right for us?
Cloud eliminates server hardware and scales across sites from one login. On-premise keeps footage entirely within your network for strict compliance requirements. 4S designs both and recommends based on your IT policy and retention needs.
Can video analytics work with our existing cameras?
Often, yes. Many existing IP cameras can feed analytics platforms without replacement. 4S evaluates your current hardware during the site walk and reuses what still performs.
How long is footage retained?
Retention is set to your policy, typically 30 to 90 days for commercial properties. Cloud systems make extending retention simple; on-premise retention depends on server capacity, which 4S sizes during design.
Do you offer 24/7 video monitoring?
Yes. 4S provides third-party 24/7 monitoring with video verification. Trained specialists verify incidents on live video before escalating, so real threats get an immediate response and false alarms don't.
Visitor Management
Visitor management systems control how guests enter your buildings, from pre-registration to check-out. 4S Security designs, installs, and services visitor management for commercial real estate, cultural institutions, multifamily properties, and corporate offices nationwide.
Visitor & Vendor Check-In
Let visitors and vendors check themselves in on a kiosk or their own phone. Front desk lines disappear, your team knows exactly who is in the building at all times, and hosts get notified the moment their guest arrives. Vendor profiles track insurance, certifications, and authorized work areas, so contractors only go where they're cleared to work.
QR Codes, Mobile Credentials & Limited Access
Issue unique QR codes or mobile credentials before a visit even starts. Guests get access only to the areas and floors they need, with guidance to their destination. Custom badge design and branding keep the whole experience professional.
Visitor Management — FAQ
How much does a visitor management system cost?
Pricing depends on entry points, kiosk hardware, and integrations with your access control platform. 4S provides fixed-fee proposals after a site walk, with no consumption metering and no surprise line items.
Can visitor management integrate with our access control system?
Yes. Visitor credentials provision directly into your access control platform and expire automatically when the visit ends. No separate system for your team to manage.
Does it work for multi-tenant buildings?
Yes. Each tenant manages their own visitors and pre-registrations under one building-wide platform, with property management keeping full oversight.
How do you handle repeat visitors, VIPs, and watchlists?
Returning guests get stored profiles for one-tap check-in. VIPs can be flagged for white-glove arrival, and watchlists automatically alert your team if a flagged individual attempts entry.
Is visitor data secure?
Yes. Visitor records are encrypted, retained to your policy, and never sold or shared. 4S configures data handling to meet your compliance requirements.
Environmental Detection
Environmental detection systems monitor your building for the hazards cameras can't see: water leaks, air quality problems, humidity spikes, and more. 4S Security designs, installs, and services sensor networks for commercial real estate, cultural institutions, multifamily properties, and corporate offices nationwide.
All-in-One Sensors
One sensor network watches your building around the clock. Water leak detection, air quality tracking, humidity monitoring, and temperature alerts report to a single dashboard, so small problems get caught before they become insurance claims.
Sensitive Spaces
Secure bathrooms, locker rooms, and private areas without cameras. Sensors detect vaping, loud disturbances, and air quality events while fully preserving privacy.
Art Monitoring & Detection
Protect the pieces your building exists to house. Discreet sensors detect touch, vibration, and proximity around high-value artwork, while continuous monitoring tracks light exposure against conservation standards. Curators get instant alerts when conditions drift or a piece is disturbed, and every reading is logged for insurance and provenance records. Museum-grade protection without a single visible camera in the gallery. The system integrates with your curatorial platform and your existing security systems, so collection care and building security work from the same picture.
Protect High-Value Spaces
Server rooms, galleries, archives, and mechanical spaces need tighter tolerances than a hallway. Precision sensors keep temperature and humidity within spec and log conditions continuously, giving you documentation for insurance claims and compliance audits.
Environmental Detection — FAQ
How much does an environmental detection system cost?
Pricing depends on sensor count and the areas you need covered. 4S provides fixed-fee proposals after a site walk, with no consumption metering and no surprise line items.
What can environmental sensors detect?
Water leaks, flooding, humidity, temperature extremes, air quality (CO2, particulates, VOCs), and in privacy-sensitive areas, vaping and noise anomalies. One platform covers them all.
Can sensors integrate with our existing building systems?
Yes. Sensor alerts feed into your building management system, access control platform, or our 24/7 monitoring center, so the right people get notified the moment something triggers.
Do the sensors need WiFi to work?
No. 4S designs the sensor network around your building's infrastructure, using wired, WiFi, or cellular connections as the site requires.
Who responds when a sensor triggers an alert?
Alerts route to your facilities team, our 24/7 monitoring center, or both, according to the action plan built for your building.
