As i can see , the circuit has a big problem ! when optocoupler is on , the transistor can be destructed because you don't have any resistor in BE diode , path .

Hi AlexAnd where does the BE path diode current come from?
I think you should reconsider...
Yes, use diode over relay (1n4007).
Use additional optocouplet to avoid overloading output transistor inside camera
.
thanks but i wont have an LED in my circuit so does that mean i dont need the 2.2 K resistor?
I want the relay to turn on and switch a light connected to that relay can i use a 24V 2A supply?
thanks but im not using an LED. The LED was shown by the manufactures as an example.
I want to switch an optocoupler with the output from the camera and have a 2A Light connected to the optocoupler
I.E camera output is on - my optocoupler comes on- then my light draws 2A from the 24V supply and switches on.
Then use 1A 24VDC for light on relay contact.

Mercedes make cars for speed 300km/h but that dont mean that you must drive 300km/h.
