How much do computer scientists make

Where you place the camera lens is important. The distance of the camera from its subject should be carefully considered, making sure the right areas are in focus and clearly visible. If you mount a camera to a wall or structure, make sure it's mounted properly so the camera won't shake and distort the picture. Outdoor cameras can deter criminals from ever attempting a break-in, Security Connection and they can cover large areas, but a camera placed outside should have an appropriate weatherproof casing to protect it from the elements. Tough casings can also prevent tampering or vandalism.

You should also determine whether or not you'll want to record your surveillance. If you're simply making sure your children are safe while playing or monitoring who comes to the front door, a direct video feed with no recorder should be sufficient. But if you wish to see what's happening in a particular area over long periods of time, you should connect a recording system that's compatible with your security cameras. Some people use VCRs to record video, while others run the whole system via a computer and save information digitally.

 To avoid wasting video, some surveillance systems have motion detectors that only begin recording once the device picks up movement within the area.

As you can see, there are many video surveillance options available. Choosing the right one for your personal needs is a matter of knowing how you want it to work for you.
