Surveillance has become very popular in today’s age and not only for catching criminals but for many other purposes as well. So if you need surveillance, a CCTV (closed-circuit television) camera system is the way to go.
Usage
A CCTV camera can serve as a deterrent to prevent crime, it
can document traffic, and it can actively monitor. The camera itself helps to
detect any activity in your home, or in companies, and in case a crime occurs,
you have a recording of it as evidence. When it comes to monitoring, a CCTV
system can give you live feeds if you want to monitor patients, employees, and
so on.
Necessary Components
If you want to get full use out of a CCTV camera, then you will need some
additional equipment. Along with the camera, you need a monitor, transmission
method and a recording device. The images that are caught by the camera are
sent to the monitor either via wireless network or cables. The final product or
image is then displayed on your monitor. An essential part of the whole system
is a recording device which consists of a hard drive or a video recorder. Its
purpose is to save the footage for later use as evidence or so it can be
reviewed at a later time.
Camera Features
There are many CCTV camera lenses that you can get. However, it is best to
choose one according to your needs. The three types of lenses you’re going to
run into are a normal, wide angle and a telephoto lens. The difference between
them is, of course, in their performance and price. The cheapest one is the
fixed focal length lens which is also the simplest one because it can’t zoom in
or change focus. Overall, lenses that can zoom are always more expensive.
Types of CCTV cameras
According to their purpose, there are different types of CCTV cameras. For
example, if you need entrance surveillance, it doesn’t need to be hidden so the
camera can be larger. If it’s an outdoor CCTV camera it needs to be carefully
placed. In addition to this, you have to buy the one that can survive different
weather conditions. On the other hand, if you need a camera that is hidden it
is best to get the so-called ‘’nanny-cam’’ which is very discrete.
Camera types
Before getting a surveillance camera, you have to know which camera is used for
which purpose. First of all, there are dome-camera models designed to monitor
clothing stores and similar businesses. These are normally installed in a place
where the exact angle of the camera isn’t apparent or is hidden. This enables the
device to record when shoplifters think that the camera is not looking. A
different type of camera would be a wall camera which is pretty visible.
Moreover, some models have various options such as zoom features, infrared
vision, or they might even be impervious to bullets. A completely different
type is the hidden cam which is small, hard to detect, and often seen in spy
movies.
