What happens if you need longer wires? RCA extensions I guess? Oh and if I got this, and someone broke into my house, wouldn’t they just steal the box with the hard drive?
Here’s my advice: this is a fairly decent setup for the money, however! I have had much better success with both the image quality and the longevity of “professional” style box cameras put into weatherproof enclosures, and that operate at 24 volts instead of 12. It will cost a little more, but I think you will find the results are significantly better.
