In the world of surveillance and security, one of the more popular gadgets that are constantly used would have to be IP PTZ cameras – especially nowadays with the advancements that have been made to the technology.
As you should already know, PTZ cameras are security cameras that have the ability to pan, tilt, and zoom. There are many different types of these cameras, but they all need to have those core functions. Because they are able to pan, tilt, and zoom, these cameras can cover a wide range of vision and possibly focus on specific targets if it is desired.
On the other hand, IP cameras are security cameras that transmit their images digitally over a network. The exact manner in which this is accomplished varies nowadays, which is why you have some IP cameras that use Ethernet cables to connect them to the network (and possibly even draw power from those cables) while others are wireless.
Also it is worth noting that some IP cameras are connected to a server that makes their images accessible over the internet.
As you can well imagine, a PTZ IP camera is a camera that has both of these capabilities, i.e. the ability to pan, tilt, and zoom, as well as transmit its images digitally over a network.
The advantage of using an IP camera is simple: Where analog signals can deteriorate when transmitted over long distances – the quality of digital transmissions remain the same no matter what distance they are transmitted over.
Also, digitally transmitted images are easier to store and retrieve as they can be saved into files that are viewable on PCs and stored in hard drives, flash drives or other conventional mediums. Analog signals on the other hand need to be stored in specific storage devices such as video tapes and sometimes DVDs – but the equipment needed to do so is often prohibitive.
Because most homes nowadays have wireless networks, integrating PTZ IP cameras into existing networks is easy, and so installation becomes much simpler. Of course, in the interest of security you might want to set up an independent network – but even that isn’t too hard to do and the equipment required is relatively cheap.
In short, these cameras provide for a flexible, easy, and high quality solution that has very few drawbacks. Nowadays, they are become more and more widely used – and newer versions have various additional features that are slowly catching on, such as ‘roam’ modes, and so on.
Now that you know what a PTZ IP camera is, it should be easy enough for you to determine whether or not you want to install one, or opt for one of the more conventional analog cameras instead.
