Do you have to program these for security cameras to record

Yes, you may have to initialize and partition the drive before using it on you security camera/cctv. Unless your camera server can do it.

What is the 4 pin cable needed?

I don't know about 4 pin, but modern hard drives use SATA cables for data and another cable for power into it, nothing about 4 pins.
