Ac or dc electric strike?

Which is a 12v dc unit.

As a matter of interest, I wonder what makes you say say that? For what it's worth, my first guess (albeit with 'no confidence') would probably have been AC.

I found it on their website, from the model number.

I would suggest your issue is volts drop, basically the resistance of the cable feeding the strike, is so high, the voltage is being lost within the cable itself. That is easily confirmed, if you check the voltage at the source end, when the release is pressed, and it shows an adequate voltage.

The fix, is to install a larger diameter cable, or you could try doubling up the one you already have.

I’ve double checked readings at camera doorbell. Supply comes from video monitor and is almost 24v (see pic). However, when activated, the output from here is 2.4v (see pic). The strike - 3m cable run - also receives 2.4v, no drop.

Does the doorbell spec say that it can deliver whatever the solenoid needs?

You are looking at possibly an amp. Has this ever worked?
