Infrared (IR) security cameras are popular because they are relatively inexpensive and easy to operate, and they come with features designed to fill different needs. Wireless IR security cameras are made to run off an internal battery that usually lasts from several hours to an entire day, though they often are best when used during only part of a day. Most IR cameras can only capture black-and-white images, but some IR cameras are able to record in color, which is useful during daytime recording. Dome IR cameras take their name from their shape and are easy to move around, though they are not weatherproof and should only be used indoors. Bullet, or cylindrical, IR cameras are cylindrical in shape and are weatherproof, making them suitable for outside use.

Wireless IR security cameras come in several different shapes, but the main factor that characterizes these cameras is that they are wireless. Unlike other cameras, which are connected to a power source, wireless IR cameras run off an internal battery. This allows the cameras to operate from four to 24 hours before needing a recharge. These cameras are typically smaller than others and are commonly cylindrical or flat.

IR cameras record using the IR spectrum, so they typically only pick up black-and-white images. Despite this, there are IR security cameras capable of recording color images. This makes them good for areas in which color would help identify thieves or trespassers, or for daytime use.

Dome IR security cameras are shaped like a dome and are commonly found in retail stores. Their shape makes it is easy to move the cameras to capture an entire area. Some dome cameras come with a plastic or glass covering, so people cannot tell where the cameras are pointing; this makes them more efficient at securing an area. Except for special models, dome cameras can only be used inside, because they generally are not resistant to rain or weathering.

Bullet cameras look like their name would suggest and are commonly used outside, even though they also may be used inside. Bullet IR security cameras have a plastic or metal covering, meaning they are resistant to outside forces. These cameras may be able to move, but the movements are typically limited, which is why they tend to be used outside. Motion sensors are normally used with these cameras, so the establishment using the cameras can save money while keeping an area secure.

@KaBoom - Wireless cameras are definitely more convenient in some regards. However, as the article said, some of them have batteries that don't last very long. It would be pretty annoying to have to charge up a security camera every four hours, don't you think?

I think a wired camera is a better idea if you know you're going to want to monitor an area continuously. You can plan ahead and work out the electrical requirements for the camera ahead of time. That way you don't have to worry about the thing running out of battery power just when you need it!

I think that wireless is really the way to go with any security camera. Imagine how much more convenient it must be to simply place the security camera wherever, and not have to worry if it's near an outlet? I think this opens up a lot of options.

I also think the dome cameras sound quite effective! With some kinds of cameras, you can see where the camera is pointing. But like the article said, with a dome shaped camera, no one knows except the person who set it up. I think this would definitely stop potential thieves in their tracks.
