What you want would be a security camera with clear night vision, one where you can clearly see who or what’s on the other side of the camera lens. Isn’t one of the things you’d want your security camera to be able to do is to see in the dark? It’s good that most security cameras are now equipped with night vision. Your security camera’s night vision is important. Also, in some security cameras you can define specific zones or grids where movement is critical. You may also adjust the sensitivity of the motion detectors so that it only goes off at significant events. If you are remotely connected to the system via a phone app, you’d immediately receive a notification about the event and you can view the video live. Depending on what storage device the security system comes with, the event is saved for you to view at a later time. Some security cameras only record events when their motion detectors are triggered then after a few seconds the recording stops. This is a very important feature of security cameras because typically this switches on the recording of an intrusion. Therefore, you’ll want a camera with a wider field of vision for your yard, and settle for something narrower for doorways.

How wide the ideal field of vision of a security camera depends on what area you need watching, for example, a doorway is narrower than an entire yard. Some dome-type cameras can give you 355° – 360° view of a designated area. You’ll see different numbers on how wide the field of vision is of a security camera - 110°, 122°, 131°, 133°, 140°, 147°, or 180° view. Cameras differ in how wide the angle of coverage is either from side-to-side or sometimes both side-to-side and up-and-down.
