Property crimes happen around the world and no matter how much we try to eliminate them, they still happen. In addition to that, a number of different violent crimes have continued to happen on private property, businesses, and more. In order to stay safe you need to take steps to protect your property. One of the most common steps is to install cameras.
CCTV and surveillance cameras are the two options that you
are most likely to have access to. Both options are popular and have been
around for quite a while now. But just because they have been around, doesn’t
mean that people know the difference. One of the most common questions that
security companies receive is: what is the difference between CCTV and
surveillance cameras?
To help you understand the difference we are going to go
into a little detail to explain what each one is.
Closed Circuit Television
CCTV stands for closed circuit television. It is a
technology that was designed to be transmitted throughout a facility in order
to view cameras and eventually to record the images those cameras. In order to
transmit the data throughout the facility a specialized cable is used. That
cable leads from the cameras to the recording device.
These cables are only connected to the camera and the
recording device (a DVR/NVR). By doing this you have a closed circuit, one that is
not exposed to outside influences. For example, in a traditional CCTV system it
is not connected to the internet.
Modern CCTV systems do allow for connection to the internet,
but it is through the recording box and only optional. You do get limited
access to the system when you used closed circuit television over the internet.
In addition to that, CCTV in general is very limited on the features.
You can only plug so many monitors into CCTV systems before
the image quality is reduced. And you are limited to 720 HD to start. A
somewhat old image format.
Many people turn to CCTV cameras because the same lack of
features works to protect the network. It is isolated and prevents hacking of
the system. A burglar will have a much harder time turning a CCTV system to
their side if it is setup properly.
Surveillance Cameras
Surveillance cameras are what most people think of now when
they think of using cameras for security purposes. These cameras use a variety
of techniques to communicate data to a recording device then to a monitor. In
most cases they use a network of some kind.
Two major types of network technology are used in modern
surveillance cameras. IP cameras is the most popular and easiest to use. IP
stands for Internet Protocol and is a method for transmitting data over the
internet or through ethernet cables. The other method is wireless networking,
the same type of technology you use to connect your computer to a router.
The design of connecting these cameras to the internet in
order to run means that you can easily connect them to the internet. You can
watch the cameras from anywhere that you can access the internet.
Because of the higher amount of information that can be
communicated by network connections, you are able to do much more. Higher end
point-tilt-zoom cameras are available, as well as night vision and thermal
vision. Overall quality can also be extremely higher. 1080P and 4K UHD cameras
are available, allowing you to make out just about any detail that you want.
Further, surveillance cameras are better able to handle
expansion. More devices can be added and you can have very complex systems.
These complex systems also have more features available on the network video
recorder (NVR). Think of high quality motion alerts and facial identification.
Crowd counting is also possible.
