So I have a Hik-Vision DS-KB8113-IME1 IP door bell that has a "door trigger" relay that you can fire from the app.
I hooked this up to my old school ET 500 Gate motor as it has a wire in trigger.
The trouble is the relay on the doorbell is set to its lowest "open time/ trigger time" of 1 sec. This is unfortunately to slow for my ET 500 and is resulting in a double trigger event, i.e. the gate stops half way. I can reproduce the issue with the standard remote by holding in the button too long. As far as I can tell there is no way to change the timing on the ET 500 and I have tried all configurations on the doorbell. A trigger signal longer than I'm guessing 0.5sec triggers a new event on the gate motor.
Solution
I need to shorten the duration of the trigger signal. Reading a thread on this site I see it may be possible to use a capacitor with a bleeder resistor to solve this.
As I understand it, the capacitor would in this case ideally spend the first 0.8 sec charging and only fire at the end. The bleeder will discharge the capacitor between trigger events.
Question
If this is a viable solution (I'm a total noob at circuitry) and as the trigger is a 5V signal from the gate, what size/type capacitor and bleeder do I need?
Thanks
