Top 10 Mistakes Companies Make When Installing Access Control & Time Attendance Systems
Implementing access control and time attendance systems (biometric fingerprint, face recognition, card-based, etc.) can significantly improve security, streamline attendance tracking, and reduce payroll errors in offices, factories, and warehouses across Bangladesh.
However, many companies—especially in Dhaka and other cities—end up with unreliable systems, frequent complaints, high maintenance costs, or even security vulnerabilities due to common installation mistakes.
Here are the top 10 mistakes companies make — and how to avoid them.
1. Choosing the Wrong Technology for the Environment
Selecting cheap or mismatched devices (e.g., optical fingerprint scanners in dusty factories or outdoor areas) leads to high failure rates. Avoid it: Choose capacitive/live finger detection sensors for dirty/humid environments. For outdoor use, go for IP65+ weatherproof models.
2. Incorrect Height & Angle of Biometric Readers
Mounting fingerprint/face readers too high, too low, or at awkward angles causes repeated failed scans and employee frustration. Best practice: Fingerprint reader at elbow height (~110-120 cm), face recognition at eye level (~150-170 cm) with proper tilt.
3. Skipping Professional Site Survey & Planning
Installing without mapping doors, user flow, power points, and network coverage results in blind spots, extra cabling costs, and rework. Solution: Always get a professional site survey before purchasing hardware
4. Poor Cable Management & Installation Quality
Messy, exposed, or low-quality cables lead to failures, short circuits, and fire hazards. Avoid: Use proper Cat6 cabling, conduit pipes, cable ties, and label everything.
5. Ignoring Emergency Exit & Safety Compliance
Installing magnetic locks without proper fail-safes (push-to-exit buttons, break-glass, and fire alarm integration) violates safety codes and endangers lives. Must-have: Always include free egress hardware.
6. Overloading Network Without Proper Infrastructure
Connecting too many IP-based devices to a weak switch or poor network causes delays, disconnections, and attendance failures. Fix: Use dedicated PoE switches with sufficient power budget and bandwidth.
7. Not Training Employees Properly
Employees misuse devices (wrong finger, dirty hands, wrong angle) → high false rejection rates and complaints. Solution: Conduct mandatory training sessions post-installation.
8. Buying Low-Quality or No-Name Brands
Cheap devices from unknown sources fail quickly, have poor support, and have fake biometrics. Recommendation: Stick to trusted brands like ZKTeco and Hikvision—available in Bangladesh with warranty.
9. Exposing Devices to Direct Sunlight or Extreme Weather
Placing outdoor readers in direct sun causes overheating, screen glare, and sensor damage. Avoid: Use sunshades, proper enclosures, and select high-temperature-rated devices.
10. No Backup Power or Redundancy
Power cuts (common in BD) lock people out or lose attendance data. Essential: Install UPS for controllers + backup batteries for door locks.
Avoid these mistakes, and your access control and time attendance system will run smoothly for years.

FAQ
Q: Why do access control and attendance systems fail so often?
Because of wrong device choice, poor wiring, weak network, and no backup power, not the core technology.
Q: What biometric is best for factories?
Rugged, IP‑rated fingerprint or face devices designed for dusty, humid environments work best.
Q: Do I really need backup power?
Yes. A UPS and backup batteries keep doors working and data safe during power cuts.
