DorTag Plus Access System – 2 Door
The DorTag Plus reader is an RFID proximity reader head (antenna) used with RFID Proximity cards & Key Tags control.
Core Features
RFID Reading
- Reads 125 kHz proximity tags/cards
- Typical technologies:
- EM4100 / TK4100
Physical Design
- Compact reader head (antenna type)
- Often:
- Plastic or stainless steel housing
- Wall-mounted near entry point
Indicators
- LED (bi-colour) for status
- Buzzer for read confirmation
Technical Specifications (Typical DorTag Reader)
| Parameter | Specification |
|---|---|
| Frequency | 125 kHz |
| Read range | 6–10 cm |
| Voltage | 5–12V DC (from controller) |
| Current | Low (≈30–50 mA) |
| Interface | Wiegand / proprietary |
| Cable | Multi-core (5-core typical) |
| Environment | Indoor / sheltered outdoor |
Read range depends on tag type and mounting surface
Functional Role in System
What the reader does:
- Detects RFID card/tag
- Sends unique ID to controller
What it does NOT do:
- Does not store users
- Does not control locks directly
All logic is handled by the controller (e.g., DorTag VI)
System Integration
Typical wiring:
Reader → Controller
- Power (+ / –)
- Data lines (D0 / D1 or similar)
- LED/Buzzer control
Controller → Door system
- Relay output → lock / gate motor
Use Cases
- Entry reader (outside door)
- Exit reader (inside door, optional second reader)
- Gate access control
DorTag systems can support:
- 1 reader (entry only)
- 2 readers (entry + exit)
Important Practical Notes
Compatibility
- Must match:
- DorTag controller
- Frequency (125 kHz)
Cable limits
- Max ~15m with shielded cable
- Poor wiring = unreliable reads
Security
- Uses low-frequency RFID
- Easy to deploy, but:
- Lower security than MIFARE systems
Position vs Other Readers
| Type | Example | Use Case |
|---|---|---|
| DorTag Plus reader | Basic proximity | Small access systems |
| Keypad reader | RFID + PIN | Medium security |
| MIFARE reader | Encrypted | High security systems |
| Long-range reader | Vehicle access | Industrial |
