photocell switch 12v

[thewireguys 3]

Anyone have any links to a 12V photocell switch. I would like to power the switch with 12 or 24 volts and it must have a relay output. Thanks

What exactly are you trying to do?

the customer wants to trigger recording when the light comes on. The camera has a dry contact input and I would like to power the photocell with low voltage so I don't have to use my electrician. Option B is to use a relay off the light switch.

I like the idea, but keep in mind these photocells have a very large lag time of 15-45 seconds. I'm not sure this would be best if you want instantaneous ON.

Yea I guess they would have a swing time.... I would have to test it. I could compensate with pre event recording but I would like to trigger right way
