Everyone's Going 360By Ethan Ace, Published Oct 23, 2012, 08:00pm EDT
For more than a decade, panoramic cameras have been the next big thing (remember IPIX?). However, adoption struggled for year, but now new product options and integrations are increasing their acceptance. In this note, we examing the reasons for this slow trend, recent announcements which impact the panoramic market, and future prospects.
Though panoramic cameras gained attention over the years, market adoption has been sluggish, to say the least. The two biggest problems were:
- Limited number of manufacturers offering panoramic cameras (e.g., Mobotix, Grandeye) forced users to go to new suppliers for models.
- Limited amount of VMS integration blocked immersive panoramic cameras from being used effectively. While a web browser separate from the VMS could be used, most found this highly disadvantageous.
Value of 360º Cameras
Panoramic cameras claim "doing more with less" as the key value proposition. Installing a single camera offering a 360º view provides greater situational awareness than a single camera normally provides, though at the loss of detail in the scene, as pixel density drops very quickly.
360º cameras (both single-imager panoramic and multi-imager) also reduce licensing costs by requiring only one license instead of multiple cameras and licenses to cover the same area.
In the past year, several developments have improved panoramic cameras' positioning in the industry:
- At ASIS 2012, industry giant Axis displayed its first 360º fisheye panoramic camera, the M3007-PV, projected for release later this year.
- Also at ASIS 2012 Panasonic announced two 360º panoramic cameras for indoor and outdoor use.
- These above releases are in addition to panoramic models from mainstream manufacturers D-Link [link no longer available], Vivotek, and ACTi, as well as expansions of Sentry360 (up to 10MP) and ImmerVision (releasing a 5MP-rated lens).
- Aside from new camera models, VMS support has also increased, with new integrations announced by Genetec, Milestone, Exacq, OnSSI, and others in the past year.
With Axis and Panasonic joining most of the Taiwanese manufacturers and a number of other global providers, getting a panoramic from one's preferred vendor is no longer that difficult.
Announcements from other, lesser-known camera manufactuers and VMS providers have also further increased panoramic cameras' market presence.
Remaining Barriers to Adoption
Though support and product options have increased, there are still a few remaining barriers to widespread adoption of panoramic cameras:
- SDK integration: Most panoramic camera manufacturers require a separate SDK for dewarping and immersive (ePTZ) controls. This makes integration to VMS systems challenging, as many software providers are hesitant to devote development resources to integrate multiple manufacturers using a technology which has seen relatively little demand. In many cases, these integrations are performed only when there is a real-world business case to drive demand for a specific panoramic camera. Note, though, Axis's alternative SDK approach for its new 360 series.
- Performance: As we discussed in our tests of Mobotix Q24 and GrandEye, panoramic cameras have definite tradeoffs in image detail, dynamic range, and low light capability. These issues need to be carefully considered. Single and multi-imager cameras are somewhat better able to compensate for WDR, and a few models that support a C/CS mount fisheye lens can allow for better (but larger) cameras to be used.
- Multi-imager impact: Arecont has had much success with their 180º multi-imager SurroundView cameras (see our 20MP test results), despite performance and build quality complaints. This line delivers panoramic imaging without any special SDK integration nor dewarping plus much greater pixel density than fisheyes. However, despite the value, Arecont remains one of the few open multi-imager panoramic providers in the market. Until we see more of this style, the panoramic market will not reach its full potential.
Undeniably, panoramic cameras are better positioned today than they have ever been. Users now have more options in both cameras and VMS support. However, users may still see some disappointment stemming from panoramic support by their preferred platforms, as well as camera performance issues.
