Review on XVIM 8CH 1080P Security Camera System with 1TB Hard Drive - 4pcs HD 1920TVL Cameras for Home Surveillance with Night Vision & Remote Access by Lee Rodriguez

HUGE TIP for mounting your cameras! If you want to keep the cameras horizontal so they look right on the screen without having to turn your head to see things as they should be, this could save you lots of time. Since you are EXTREMELY! limited to the way you can position your camera, only up and down, while keeping it horizontal, place the camera where you are thinking of mounting it then start a screw in 1 of the 3 holes which will allow you to swing the camera left and right. Have someone watch the screen as you slowly move the camera left and right. When the person watching the screen says it is level and they can see what you need to see from the camera, start your other 2 screws. Now, tighten all three and you should be level. I had to do this and for 2 of my cameras. I had to go to my local hardware store to buy small aluminum shelves to mount the other 2 cameras on. The shelves allowed me to move the cameras left or right so I could see the entire area I needed to see, while keeping things level, then I set them up or down as needed. It took a little trial and error to get them all mounted but these are the two steps I did. I know more expensive systems have more flexible mounting hardware but you get what you pay for and this is all I needed for my situation. I hope this helps and isn't too confusing. Good Luck.
