Gate call boxes: same box, new line
The gate call box, its keypad and its programming stay as they are. Only the copper behind it is replaced.
How it works
A solar box on a post near the gate connects to the call box's existing phone line. No trench back to the building, no AC at the gate. We test calls to every number the box dials. Gate control (codes, relays) is untouched.
- No new device, no reprogramming
- Two boxes on a post at the road, solar powered
- Copper business lines are billing $200–2,700 a month. Cellular service for a line typically runs $15–45 a month.
