First evaluate how you will use it. What do you need to accomplish with the use of a CCTV?
When should you buy black and white verses color?
- Obviously the first issue is what can you afford. But money aside, if you will be using the machine primarily to read text, then buy a black and white unit. Reading material is generally in black and white image anyway. Consider multi-color options for high contrast needs. A color system is great for looking at photos, maps, recipes, magazines, and working with crafts.
What monitor size should you use?
- The smaller the monitor is the higher the resolution is. However, if a person is using more then half to two third magnification then I recommend a bigger monitor. Keep in mind that the individual can make the image smaller in a larger monitor, which produces a greater field of view.
Two-piece units should be used when an eye condition needs greater separation between monitor and camera. This allows them to access the x/y table while the screen is a distance away.
When should options be used?
- Different color combinations are ideal when a person sees certain colors better, or requires high contrast.
- Line marking and windowing is ideal when a person needs to isolate text.
- Computer options are ideal when a person needs to work with a computer and a CCTV.
- Split screen computer systems are ideal when a person needs to transpose material.
- Auto Focus is ideal when a person needs to keep it as simple as possible. Manual focus override on an auto focus system allows for maximum versatility and allows complete control over unique viewing situations.
