What is multi-door interlocking (mantrap) and where is it used?

Multi-door interlocking connects two doors electronically so that Door B cannot be unlocked or opened until Door A has closed and magnetically locked completely. This is commonly used in high-security bank vaults, jewelry strong rooms, and cleanroom laboratories to prevent tailgating.

Why should we procure access control through Microtech Solutions instead of buying basic clocks online?

Procuring through Microtech Solutions ensures your access control system is engineered and installed by certified security professionals. You receive professional pre-sales door frame surveys, precision glass U-bracket mounting, dedicated 12V battery backup enclosures, emergency break-glass life safety integration, custom Tally payroll configuration, and local onsite engineering support across Kolkata.

What happens to the door lock and attendance logging if building electrical power cuts out?

Every enterprise system we deploy includes a dedicated 12V 5A power supply controller enclosure equipped with an internal rechargeable sealed lead-acid battery. When mains power cuts out, the system transitions to battery power in zero milliseconds, keeping the EM lock magnetized and the biometric terminal recording punches for 4 to 6 hours.

What happens if a door is held open with a doorstop or wedge?

When magnetic door status sensors detect that a door has remained open longer than the configured timeout (e.g., 30 seconds), the system sounds a local warning buzzer on the terminal and generates an alert on the administrator's dashboard indicating a 'Door Ajar' security event.

What is an electromagnetic (EM) lock and how strong is its holding force?

An electromagnetic lock consists of an electromagnet mounted on the door frame and a steel armature plate mounted on the door face. When energized with 12V DC power, it creates a powerful magnetic bond. Standard commercial locks deliver 600lbs (280kg) of holding force for office doors, while heavy-duty models deliver 1200lbs (500kg) for strong rooms and perimeter gates, making them impossible to push open by hand.

Who owns the biometric database, administrator passwords, and shift configurations?

You do. At project sign-off, we deliver a complete documentation package containing your master terminal IP addresses, administrator credentials, shift configuration maps, wiring diagrams, and warranty certificates. Your company maintains complete administrative ownership.

How do employees exit the office from the inside?

Staff exit from the inside by pressing a stainless steel push-to-exit button, waving their hand in front of a touchless infrared exit sensor, or presenting their biometric credentials to an internal exit reader. The controller releases the EM lock for a configurable duration (typically 3 to 5 seconds) allowing the door to open.

Can staff clock in quickly during morning shift rush without forming long queues?

Yes. high-throughput facial recognition terminals process faces in under 0.2 seconds from up to two meters away. Employees walk past the terminal at normal walking pace, allowing up to thirty to forty staff members to clock in per minute without forming bottlenecks.

Why should our business use a biometric access control system instead of manual paper registers or keys?

Manual paper registers allow buddy punching, contain illegible handwriting, and require days of tedious spreadsheet reconciliation every month. Physical keys can be easily duplicated, lost, or stolen, creating security loopholes. A Biometric Attendance and Access Control Systems uses touchless AI face recognition and fingerprint matching that prevents proxy attendance completely, unlocks doors only for authorized staff, and generates payroll-ready digital reports in seconds.

Can the biometric terminal be mounted outdoors at factory turnstile gates?

Yes. We deploy industrial-grade terminals featuring IP65 weatherproof metal housings and wide-temperature operating ranges engineered to withstand outdoor dust, rain, and direct sunlight when installed on factory entrance turnstiles.

Can we restrict employee access to specific doors and specific hours?

Yes. Access control software allows configuring granular time zones and access groups. For example, general administrative staff can unlock main entrance doors only between 8:30 AM and 7:30 PM on weekdays, while server room entry is restricted exclusively to authorized IT personnel 24/7.

What is an emergency break-glass unit and why is it mandatory for life safety?

An emergency break-glass unit is a high-visibility green call point installed on the exit side of an access-controlled door, wired directly in series with the 12V lock power circuit. In a fire or emergency, pressing the break-glass physically interrupts power to the electromagnetic lock, releasing the door instantly for safe mechanical evacuation without requiring biometric authentication.

How does touchless AI facial recognition prevent buddy punching and photo spoofing?

Touchless AI facial recognition terminals use dual-camera infrared sensors and 3D liveness detection to evaluate facial geometry, skin texture, and depth. The system matches faces in under 0.2 seconds and automatically rejects printed color photographs, mobile screen replays, and video spoofs, ensuring that only the physically present employee can register attendance.

What maintenance is required to keep our biometric access system operating reliably?

Routine maintenance includes testing 12V backup battery runtimes, checking EM lock armature plate alignment washers, cleaning optical fingerprint prisms and camera lenses, verifying emergency break-glass operation, and reviewing automated payroll export rules.

Can biometric access control be installed on frameless glass doors without drilling glass?

Yes. We use specialized precision-machined aluminium U-brackets designed specifically for 10mm to 12mm frameless tempered glass doors. The U-bracket clamps securely onto the top edge of the glass door using high-density rubber pressure pads and grub screws, providing rock-solid mounting without drilling or damaging the glass.

📞 Annual Maintenance and Renewal for Biometric Attendance and Access Control Systems close to Salkia

Technician terminating 4-core copper wiring into a 12V battery backup power supply controller box

Running separate power wires and communication cables haphazardly across a glass reception partition looks unprofessional and creates snagging hazards. An enterprise Biometric Attendance and Access Control Systems is installed with structured, concealed wiring pathways: multi-core pure copper cabling is routed through decorative aluminium conduit or door frame profiles, exit push buttons are flush-mounted, and the central power supply is housed inside the server room cabinet. Installation is neat, aesthetic door finishes are preserved, and all door hardware is backed up by central UPS power.

Your current attendance setup consists of three standalone card machines purchased years ago from different vendors, each requiring someone to manually carry a USB pen drive to each machine on the first of every month. Consolidating your organization onto a unified Biometric Attendance and Access Control Systems infrastructure connects every terminal over local TCP/IP networks, office Wi-Fi, or direct 4G SIM modules to a centralized server. Punch logs download automatically every ten seconds, multi-branch employee attendance is visible on one screen, and HR generates consolidated reports without travelling to site.

👍 Why Owners Stop Worrying About This close to Salkia

An access control system that lacks responsive local engineering support during a lock failure is a severe business hazard. Every terminal and lock we supply carries authentic serial numbers registered directly to your company, backed by official manufacturer warranty coverage and our local certified engineering desk in Kolkata. If an EM lock requires realignment or a sensor requires diagnostics, our engineers attend promptly.

Business leaders do not want to spend hours reviewing raw timestamp logs; they want clear visibility into employee punctuality, department attendance percentages, and unauthorized door access attempts.

When auditors or HR directors request workforce records, you have verified reports ready to share.

CA, Legal and Financial Practices: Confidential Room and Partner Access

A private educational institution with over 150 faculty and administrative staff in Kolkata required automated time-attendance linked to their central staff management portal. We implemented biometric terminals across staff rooms and administrative offices, configuring automated SMS alerts for late arrivals and monthly leave balance integration. Faculty attendance tracking operates with complete transparency, and administrative overhead was eliminated.

🛡️ WHO ACTUALLY COMES TO YOUR PREMISES

Conduit Routing, Glass Clamping and Grounding Standards

Hardware sizing is where most business biometric projects go wrong. We ask how many employees clock in during shift rush hours, whether doors are frameless glass or wooden, what battery backup runtimes are required, and what payroll software you run - then configure the terminal models and lock power controller that handle that workload with multi-year expansion headroom.

Here is the commercial access control engineering work we take on, quoted transparently before we begin:

🧠 Lessons From Deployments That Went Wrong throughout Kolkata

Use 100% solid bare copper 4-core or Cat6 cabling for all lock power runs. Cheap copper-clad aluminium (CCA) wires introduce high electrical resistance over 20-meter runs, causing 12V lock voltage to drop to 9V, which weakens magnetic holding force significantly.

Consumer plastic attendance clocks lack industrial dust and moisture ingress protection, failing quickly in factory environments. Industrial-grade terminals feature IP65 weatherproof metal enclosures and scratch-resistant optical sensors built for factory gates.

Standard door setups require manual key management that risks duplicate keys and unauthorized copies. An enterprise access control system enforces digital permissions: access can be granted or revoked in seconds from a web browser without rekeying physical locks.

💡 Engineering Fact: Anti-Passback security rules require an employee to register a valid entrance punch before the system will accept an exit punch, preventing card sharing.

Frequently Asked Questions

Q. How does the biometric attendance software mix with Tally Prime and payroll?

The time-attendance software processes raw punch logs through customizable shift logic, grace periods, half-day rules, and overtime calculations. It generates clean monthly attendance muster rolls that export directly into Tally Prime, Busy, SAP, or custom HRMS platforms with one click, eliminating manual data entry.

Q. What is the difference between fail-safe and fail-secure door locks?

Fail-safe locks (like electromagnetic EM locks) require continuous power to stay locked and unlock automatically when power is removed, making them standard for office exit doors to make sure safe fire evacuation. Fail-secure locks (like electric strikes) remain locked when power drops, requiring manual key overrides, and are used for high-security storage vaults.

Q. What is Anti-Passback and how does it prevent card sharing?

Anti-Passback is a security rule that requires an employee to register an entrance punch before the system will accept an exit punch (and vice versa). If an employee clocks in and passes their access card back to a colleague behind them, the system blocks the second punch and sounds an alarm.

Q. How does the terminal handle employee registration across multiple branches?

Employee facial or fingerprint templates are enrolled once at head office. Using centralized cloud management software, the employee's template is synchronized automatically to designated branch terminals across Kolkata over the network, eliminating manual re-enrollment when staff transfer between locations.

Q. What is Push Data Protocol and how does it sync multi-branch attendance?

Push Data Protocol (HTTP/HTTPS) allows biometric terminals at branch showrooms or warehouses to set up outbound cloud connections and push punch records automatically in real time over local broadband, Wi-Fi, or 4G. HR teams view centralized employee attendance across all locations on a single web dashboard without setting up static IP addresses at each branch.

💡 Engineering Fact: Touchless AI facial recognition terminals use dual infrared and visible-light cameras to measure 3D facial contours, rejecting printed photos and video replays.
