property, but they can also be useful for other purposes as well. Read on to learn
more about these cameras and how they can benefit you.
Infrared cameras
The pixels on an infrared camera react to infrared energy and a camera processor
applies a mathematical calculation to each one to form a color map of the apparent
temperature of the object. This matrix is then sent to memory and displayed on the
camera’s screen. Some infrared cameras come with a visible-light camera that
automatically captures a standard digital image with every trigger. This allows the
user to correlate problem areas in an infrared image with the actual equipment.
Bullet cameras
Bullet security cameras are an excellent option for outdoor surveillance. They can be
mounted on poles, walls, overhangs, and fences, and have wide angles for
monitoring long distances. These cameras can also act as deterrents to would-be
vandals. Bullet cameras come in different types, each with its own unique features.

features, such as night vision and audio recording.
Analog cameras
Analogue cameras are the old-school types of CCTV devices. They require a large
amount of cabling, and are difficult to install and scale. IP cameras, on the other
hand, can use a network video recorder that can connect to several IP cameras
without the need for separate cables. The downside of this type of CCTV is the cost,
since IP cameras are able to transmit data at a higher rate.
TVI cameras
Among the most popular types of CCTV devices are TVI cameras and IP cameras.
Although these two types of security cameras are similar, they differ greatly in their
features. A TVI camera transmits an analog signal over a coaxial cable. Its release in
2014 made it the most common analog HD security camera technology in the United
States. Big manufacturers such as Dahua and Hikvision were among the first to
adopt this new technology. Another popular choice is CVI (composite video
interface), which is not very common in the United States, but is popular in China.
Wireless cameras
A wireless security camera is a security device that transmits video and audio
signals to a receiver via a wireless connection. A wireless camera may not have a
cable for power. The word “wireless” simply refers to the way the camera transmits
the video/audio signal. Most wireless security cameras do require some form of
cable to power them. This cable can also be used to transmit video/audio.
