As a rule of thumb, there are some general costs you can keep in mind.
A complete keypad (pin only) system for single door security access is typically $800 to $1000 including installation, OR
Proximity card system from S$1,000 to S$1,400 including installation, OR
Fingerprint biometric system is typically S$1,200 to S$1,700 including installation.
Face recognition biometric system is typically S$1,400 to S$1,900 including installation.
Double-leaf door (i.e. the door has 2 movable panels) will cost more. Glass door installation will cost more than wooden door installation as the accessories used are different.
Similarly, having an access control system for a door that can swing both ways will cost more as compared to a typical door that can only open one way (either in-swing or out-swing).
