Physical SecurityAccess Control
Open doors with a card, face, fingerprint or phone. Decide who goes through which door and when, and see every entry.
What we usually find on site
Keys can be copied at any key shop, and people who've left may still have one. When cash or stock goes missing, nobody can say who went in and when.
The system is made up of readers, controllers, electric locks (mag locks or electric strikes), exit buttons, door contacts and management software. The part that usually gives trouble isn't the reader, it's the door: a door that's out of alignment or a weak closer stops a mag lock from seating. We check every door during the survey.
Choosing credentials
- Cards: avoid 125 kHz (EM/Prox). They're unencrypted and can be cloned with a cheap gadget. Use encrypted cards such as MIFARE DESFire EV2/EV3 or iCLASS SE/Seos.
- Face: touchless, fast, can't be lent. Pick models with liveness detection so a photo won't open the door.
- Fingerprint: cheap, but on construction and mine sites dirty or worn fingers often won't read. There we recommend face.
- Mobile (BLE/NFC): convenient, and credentials can be issued or revoked remotely.
- Two-factor (card + PIN or face) for server rooms and cash rooms.
People's safety first
Electric locks on escape routes must release automatically when the fire alarm sounds (fail-safe), with a break-glass button beside the door. Every system has battery backup.
The software can show CCTV video alongside each event, sync with HR so access ends the day someone leaves, and enforce anti-passback so cards can't be shared. Between reader and controller we use OSDP with Secure Channel rather than Wiegand, which sends credential data unencrypted.
What it does

FAQ
What happens to the doors in a power cut?
It depends on the design. Escape-route doors must be fail-safe (unlock). A cash-room door may be fail-secure (stay locked). Either way, battery backup keeps the system running through short outages.
Is our 125 kHz card system a problem?
For ordinary doors it may still do. For server rooms or cash rooms it doesn't: the cards are unencrypted and can be copied in seconds. Move to encrypted cards, starting with the sensitive areas.
Can the same system do time attendance?
Yes. Many platforms do both or feed a time-attendance system. See our Time Attendance page.
