Power Supply Question
Hello, just a simple question,
If I have 2x 12vdc 5a power supplies, and 6 IR cameras, plus one non IR Camera, can I put the two power supplies in parallel with eachother and run them into a camera power supply terminal block? with this give me 12vdc at 10amps? and is it safe to do?
I cant see why not but pays to check right?
Cheers!

Theoretically possible, but not recommended.
If one goes down the drain, it will take the other with it.
Far better to split the load independently between each.

If you were to connect two units, the unit with the higher output voltage will start supplying all the current until it reaches its current limit setting.
Its voltage would then drop until it matches the voltage of the second unit. The second unit will now also start supplying current, however the first unit is still sitting in an overload condition and will eventually fail.
You can get DC supplies designed to be paralleled the output voltage is matched and generally they can run at 100% current limit continuously.
You can't connect the two power supplies in parallel, as previously stated. To get yourself out of trouble, you could run 3 cameras off one power supply and the other 4 off the other one. Connect the Positive of one power supply to the positives of 3 cameras, and the Positive of the other power supply to the positives of the other 4 cameras (but keep each of the two Positive groups separate). Then join ALL of the negatives together. This will get you up and running.

Theory and practice say no!
to parallel to PSU's together, they need to be designed to do so and have a common rail.
