Some time ago I bought a Hikvision video intercom, model DS-KIS604-S(B) and I'm using it to control my sliding gate.
The intercom allows me to open/close the gate using:
- mobile app (remote aspect) -
HikConnect - indoor station
DS-KH6320-WTE1 - button
I've connected door station DS-KV8113-WME1 to Nice Robus 600 gate automation, through sockets NO2 & COM2 with SBS (step-by-step) socket.
First test. Opening sliding gate was fine. But when I triggered to close, the gate started closing. After ~20cm, the gate stopped and started opening again 😟.
Opening the gate through HikConnect door station was fine, but closing the gate was a tricky part. Door station closes the circuit at least for 1 second! And couldn't be decreased! The time resolution for Hikvision is in seconds.
On some portal I've read that SBS socket is fine for closed circuit within time range between 0.4 - 0.8 second.
To workaround this issue, I've picked an old Digispark Tiny85 and relay module HW-307 and built cheap time relay.
Probably there are better solutions, but at that time I had those parts at home.
The idea is simple, the door station closes circuit on the Digispark and it triggers relay module to close SBS circuit in gate automation.
| Digispark | Relay module | DS-KV8113-WME1 | Nice Robus 600 | Other |
|---|---|---|---|---|
| 5V | 5V | |||
| GND | GND | |||
| P0 | IN | |||
| 5V | COM2 | |||
| GND with 10k Ohm resistor to P2* | ||||
| P2 | NO2 | |||
| VIN | Positive pole of power supply ** | |||
| GND | Negative pole of power supply | |||
| NO | SBS 1st slot | |||
| COM | SBS 2nd slot |
* GND - to one leg of 10k Ohm resistor, to second leg connect P2 pin and NO2 from door station.
** VIN - in my Digispark there is 78L05 voltage regulator which accepts 30V maximum input voltage, but I've connected to 12V power supply which is also used for electric strike.
