The pan, tilt and zoom or PTZ electromechanical videoconferencing camera was introduced so far back in the mists of time, almost everyone has forgotten, or never knew, why it was necessary in the first place.  Has it had its day?

A quick bit of VC history…..

Viva La Resolution!

Modern video camera resolutions are typically measured in megapixels or millions of pixels.  Even smartphone cameras now exceed 33 megapixels but, back in the day, videoconferencing video resolution was limited to about 100,000 pixels (no, really, just 352 x 288) and these had to stretch across large display screens (usually from projectors) so that those seated furthest away could see a usable image.  So the video images weren’t great and the rooms had to be carefully designed to get the best from the limited quality.

In order for the far end to make out who was actually speaking, the PTZ camera was introduced so that you could zoom in and devote those 100,000 pixels to the current speaker.  Of course, someone had to ensure that the camera was pointing in the right direction at the right time.  In other words, someone had to “direct” or operate the camera and, in the days of the half million-pound video room, there was often a technician around tasked to do this.

When systems became lower cost and more numerous, user interfaces were created to allow the participants to control their own calls and it was at this point that PTZ control really became a pain.

---

Users were not interested in controlling the camera

---

Users were not interested in controlling the camera.  It was a distraction from the meeting and too demeaning for a senior executive to get involved with the technology.  It was also an opportunity to screw up in front of one’s peers when the technology did something unexpected (like focus on the ceiling).

So what did they do?  They set the zoom to fully wide and left it there demoting the expensive PTZ to a fixed camera, making it irrelevant and degrading the experience for the far end users – and they are still doing it.

Sure, there were attempts to resolve this using push-to-talk microphones that forced the camera to the current live mike and voice-tracking cameras which were supposed to move automatically to the current speaker.  Apart from causing sea-sickness in the viewer from rapidly-tracking images, these voice-tracking cameras were pretty bad at finding the speaker unless the whole room was set up in something akin to an anechoic chamber because the audio tracking system would often mistake a reflected audio path as the direction of the speaker and focus on the source of the reflection from, for example, an adjacent wall.  Not very helpful and, if an animated discussion broke out with multiple participants speaking at the same time, video pandemonium could ensue.

Move forward 30 years.  The big difference is the video resolution of current systems.  Most enterprise-grade videoconferencing systems can deliver at least 1920 x 1080 pixels or full HD with some capable of 4K, or Ultra HD (3840 x 2160 or around 8 megapixels).

Add to this the vast improvement in display technology and the early problems around being able to discern who was speaking due to poor resolution have gone; in most rooms, everyone can now be seen clearly so why are we still deploying PTZ cameras?  In fact they are now not only redundant, they are becoming a major problem.

Huddle Rooms

This term has been adopted to mean small rooms that have not previously been considered viable for video capability due to cost. Three big factors are coming into play to change things significantly:

• User demand: for more video collaboration facilities in the workplace.
• Cloud video services: where the large cost of the video network infrastructure is being picked up by a Videoconferencing as a Service (VCaaS) operator and clients need only pay a low subscription fee for access and
• Dramatically falling room hardware costs: It’s now possible to deploy professional-quality video into a huddle room for less than $2,000 including a large format display and these costs are continuing to fall.

It’s now possible to deploy video into a huddle room for less than US$2,000

---

Under pressure from their users for more readily-available visual collaboration facilities, organisations are pressing these Huddle Rooms into video service at a time when the above factors are combining to take away a lot of the pain.

But there is a problem with these legacy PTZs when you start to use small rooms that only seat a few people; the participants are all very close to the display and, consequently, very close to the camera.

Legacy conferencing cameras will not see the closest participants at the table

A typical PTZ camera has a field-of-view (FoV) of just 70-90 degrees. When placed in a small room, this will mean that some of the participants closest to the camera will be partially or completely excluded or it forces everyone to huddle closer than they may have anticipated around the furthest end of the table.

A Modern Solution – No Mechanical PTZ and a 180° Field-of-View

In both the security and conferencing markets (the two biggest markets for PTZ cameras) the trend today is away from electro-mechanical cameras that physically move, toward fixed, high-resolution cameras.  This is becoming possible because the resolution of low-cost cameras is becoming so large that the camera can remain static and the panning, tilting and zooming can be achieved by using software to move around the fixed image from the camera sensor.

Jabra has come up with the first new approach to the videoconferencing camera in three decades

---

The Jabra PanaCast is an industry-leading example of this move towards “soft” PTZs.  Jabra has come up with the first new approach to the videoconferencing camera in three decades and it’s both obvious in hindsight and a radical departure.

The Jabra PanaCast camera is three cameras in one with a total native resolution of close to 40 megapixels.  This provides a highly detailed image much larger than that needed in a standard video call and can support a lossless zoom of 6 times.  Meaning that the soft PTZ action can easily be accomplished within the camera’s captured image without any apparent degradation in the quality received at the far end.

In the PanaCast, Jabra has also produced the world’s first 180° 4K panoramic camera designed to cover the entire room in a single, ultra-high-definition video image.

Now, while wide-angle or wide field-of-view cameras have been around for a long time, unless you spend a huge amount of money on special lenses, they produce significant spacial and radial distortion (the so-called fisheye effect) causing the apparent size of people at the edge of the lens to be exaggerated and adding an unrealistic curve to their image while participants furthest from the camera appear diminutive in comparison.  This creates a very unnatural image unsuitable for professional videoconferencing.

Jabra took a different approach. They took three ultra-high-resolution cameras each of a more modest field-of-view and stitched the three images together dynamically in the camera while also adding image correction to produce a single video stream that can cover up to 180° with virtually zero distortion.

The result is a very clear view from even the smallest Huddle Space in which every person, whiteboard or flip-chart is clearly visible within a naturalistic image which belies the closeness of the participants to the camera.

A Typical View from the Jabra PanaCast Camera

---

Jabra PanaCast’s field-of-view is up to 180 degrees

---

And, because the image is in high definition, individual viewers or sites can pan and zoom using touch screen devices into the part of the transmitted scene that interests them most without impacting the view of any other site.  So, if I want to see the presenter or the whiteboard while you prefer to watch the reaction of others in the room, we can both do so using our own devices with no conflict.

By banishing the PTZ camera to history, one big intimidating factor in the video meeting room may be removed.  In these days of self-service visual collaboration, the technology needs to be as transparent to the user as we can make it.  The Jabra PanaCast camera is a game-changer in the video meeting room and allows organisations to expand their use of video especially into smaller rooms or Huddle Rooms and, at the same time, delivering a much-improved user experience.
