Computer security cameras come in different types, including bullet, pan/tilt/zoom, and pinhole. They have various features such as audio and visual surveillance, motion detection, and night vision. They can be used for indoor and outdoor use, wired or wireless, and can be viewed online or offline.
Bullet, pan/tilt/zoom, and pinhole are some of the different types of computer security cameras available to both consumers and industries. Multiple cameras make up a network security system displayed as a live streaming display, recorded on a computer’s hard drive or on a remote security website. These cameras have a variety of features, including audio and visual surveillance, motion detection, and night vision. Manufacturers design computer security cameras for both indoor and outdoor use, using both wired and wireless technology.
Bullet computer security cameras get their name from their distinctive bullet-shaped design. Cameras designed for outdoor use are usually housed within a weatherproof enclosure. Some have low-light technology that allows for clear viewing when on buildings that receive low levels of light from streetlights or building security lighting. Other cameras contain light-emitting diodes (LEDs) placed around the lens, which provide enough infrared light to view outdoor scenery up to 500 yards (457 meters) away. In addition to live streaming signals, some cameras can also capture still images.
Models with pan, tilt and zoom can be used as computer security cameras both indoors and outdoors. Many versions have internal fans and heaters, allowing for outdoor use in cold, wet weather conditions. These cameras are either fixed inside a dome housing or attached to an external rotating frame and require cabling to operate. Cameras change viewing position remotely via manual or pre-programmed instructions. The zoom feature allows users to magnify an image up to 36 times, depending on the make and model of the particular camera.
Pinhole cameras are typically used with in-house computer security systems. Commonly referred to as nanny cameras, the camera’s small size allows users to camouflage the device in inconspicuous areas of a home. Each camera uses a battery or plugs into an electrical outlet, sending signals to a remote receiver connected to a computer. Owners typically view the audio-visual cues as a live stream display or from a recording on a hard drive. Most models are designed for daytime use or placed in areas with adequate lighting, but some versions are equipped with a night vision function.
Individuals use computer security camera networks for both online and offline viewing. Wired or wireless cameras, just like other plug and play devices, send signals to computers. Offline systems require the computer receiving the signal to be on all the time for recording or viewing, and some computer security cameras require additional computer security software. Online systems connect directly to a website which not only records signals in real time but also allows users to view the results from anywhere.
