Over the years PTZ cameras have become more and more popular as part of security systems – and the technology that they use has steadily improved. Frankly speaking, some of the cameras today are a far cry from their predecessors, and are able to do a lot more tasks as well.
Image and Zoom Quality
One of the main areas that has seen a lot of improvement in recent times is in the quality of the image provided by the camera. Nowadays HD video recording and other technologies are readily available, though for storage purposes it is unlikely that any security camera will be set to record at such high quality.
Still, higher resolutions have become more of a norm today and that results in clearer video images.
On top of that, this clarity means that higher levels of zoom can be achieved without the image becoming blurry. Being able to zoom in to many times the original image size while still retaining clarity is one of the most useful advancements that has been made in recent times, and it increases the range and effectiveness of PTZ cameras overall.
Tracking Technology
Another area of technology that is being implemented into this type of security camera is the ability to track targets. Because they can pan and tilt to cover a wide field of vision, PTZ cameras nowadays can be programmed to ‘track’ targets and move to match them as they travel across that field of vision.
This actually uses various combinations of technology. Some cameras may be set to track objects in motion – which is useful when there is meant to be no movement as it means anything moving will instantly be focused on and tracked.
On the other hand, other cameras nowadays use facial recognition technology to focus on faces and track them the minute they cross the field of vision. Although facial recognition technology isn’t perfect, it is still a fairly useful addition as it ensures that random motion won’t end up being tracked.
In general, these are the two areas that have been undergoing heavy improvement in recent times. There are other areas that have shown some improvement as well, such as the speed at which these cameras can pan and tilt.
As time goes by it is reasonable to assume that the technology going into these types of cameras will improve them further. Considering the fact that security is an area that companies and individuals invest heavily in, there will always be a demand for better solutions as to how to secure a premises from intruders, and PTZ cameras are set to feature prominently considering their wide field of vision and ability to track and focus on targets.
