Usually the camera is located in one location and the monitors in another. Without some sort of a portable monitor, aligning the camera perfectly can be maddening. For IP cameras, the problem is even worse since it is just not possible to connect a portable monitor to the camera without an analog output.

One way around the problem is to use an optical view finger such as that offered by Computar. You can set the image sensor size ( 1/4. 1/3. 1/2. etc ) and the focal length of your lens. Then just view through the optic and “bracket” your scene. Pretty slick.. and a low cost alternative. I’m sure you can find them other places, but here’s the spec on the Computar unit.
