What Types of Camera Format Options are Available?
There are many different types of cameras available to choose from, and they each have some unique features that make them useful in different situations and for various industries. Here are the basic categories, and as always, we are here to answer any questions you may have about the right type of cameras for your needs.
Bullet cameras are named for the long cylindrical appearance, which somewhat resembles a bullet. They are highly recognizable and provide a visible deterrent to those who wish to break-in. They allow you to focus on a fixed view like a building entrance, so you will need numerous bullet cameras if you have multiple access points. They can have night vision, as well as motion-sensing capabilities. They can be mounted on a ceiling or wall and used both indoors and outdoors. They are ideal for large areas like parking lots due to long-distance viewing capabilities.
Dome cameras are similar in functionality to bullet cameras, but they have a couple of advantages. They have a wider viewing angle, which means you could cover more of an area with a single camera. Another advantage they have over the bullet cameras is that they are more tamper and vandalism proof due to being a completely enclosed unit.
Pan, tilt, and zoom cameras do precisely just that. You can control their movement with a joystick or through software. They can automatically run a specific pattern or turn to a preset location. Panning can range from a complete 360-degree circle to smaller ranges. The amount any camera can tilt will vary by model, but it can go up to 180 degrees. Optical zoom physically adjusts the camera lens, which maintains image quality and is stated as #X, like 12X zoom. Digital zooming uses software to enhance the image. This is a significant difference as digital zooming usually results in low-quality pixilated video images.
Thermal cameras use the heat generated from an individual or object to detect movement, and they do not require any light to operate. They are ideal for not only detecting persons in the dark, but they can also “see” outdoor activity in less than ideal conditions like a thunderstorm or heavy fog. The video recorded by these cameras is for detecting persons or objects in areas where they should not be located. These cameras can also see and prevent incidents before they happen in areas where hazardous chemicals are stored or in factory or warehouse settings with overheating equipment.
Unlike thermal cameras, these cameras exist for the sole purpose of detecting elevated body temperature to help prevent the spread of disease and sickness. They come in different formats like a bullet or dome camera, a walk-through solution, and handheld. They can measure multiple people in seconds and sound an alert when a person with a higher than average temperature is detected. While they cannot detect disease or sickness, they can help prevent the spread by preventing people with a fever from entering your building, factory, or warehouse
Wide dynamic range cameras can handle a comprehensive range of lighting levels all at once. What does this mean for your surveillance video? It means that these cameras provide superior clarity of images when dealing with bright and low light in the same scene, like bright headlights in a dark parking lot. You would lose a person’s facial details driving toward the camera in the parking deck with a traditional camera. The technology in these cameras can balance between the different lighting levels on a pixel-by-pixel basis.
