Innovation in video surveillance tech at a crossroads: Part 2

Experts weigh in on resolution arms race, advances in edge capabilities and video storage


Nilsson: I think as the industry moves over to IP, more and more of that storage moves off to the common off-the-shelf type of storage devices – servers, SD cards or even small NAS storage boxes which you can also get for probably $200 with a terabyte of storage and the DVR would have a difficult time competing with that. The DVR is mostly used in very small systems today, it has very low cost, but again, the SD cards are gradually moving in there as well, so I think there is more and more hardware being done as kind of a ready-made NVR for systems that are also competing with NAS and SD cards. I think, over the years, you’re going to see even fewer DVR companies. That’s my guess.

De Fina: All system related expenses are and will continue to be an issue, as end users continue to demand better performance for less. Storage is no exception despite new technologies like H.264 compression, analytics and control software that provide multiple means of reducing bandwidth and storage requirements. Technology evolution dictates that we will see new storage solutions with increased capacities at lower price points moving forward.

Piran: Video recording solutions continue to improve as disk densities, compression techniques and the means by which cameras can be programmed to change resolutions based on external triggers from analytics and control solutions like our Ocularis VMS. But costs still play a major role in the decision making process when specifying system performance and capabilities. We can expect all of these trends to continue as larger storage capacities in the terabyte and petabyte range continue to make news.

Burke: Storage is less of an issue than it was perceived to be in the past. The industry has grown smarter regarding how to effectively and efficiently optimize video recording and storage. Combine that with increased storage capacity and lower prices and you have the first mainstream edge technology that has really gained strong adoption and practice. In the future, we will see even more use of edge storage and integration with other technologies from VMS to analytics. The possibilities are enormous.

Schafer: There is a combination of factors that have affected storage capacities and cost issues. One is the on-going improvements in server and hard disk technologies combined with technologies like H.264 compression which conserves bandwidth and storage space. The other significant development is in the area of megapixel cameras where H.264 compression and features like the ability to change frame rates and resolution based on real-time events and triggers. This enables large numbers of megapixel cameras to be deployed and programmed to shift to high frame rates and imaging resolutions when triggered by an event via a VMS, DVR or some other control software prompt. There will always be issues to contend with when looking to strike the right balance between cost and performance, but as recording and imaging technologies continue to improve, both storage and bandwidth capacities will become even less of an issue than they are today.

Poulin: While there are still high costs associated with video storage, newer systems such as digital video recorders deliver outstanding performance and flexibility that maximizes the value for the end user. Purpose-built to handle vast quantities of data, high-capacity digital video recorders allow security professionals to record and manage video data without having to sacrifice the high-quality imagery captured by advanced HD cameras. In addition, the IP capabilities of digital video recorders provide end users with additional flexibility, allowing them to scale their systems while minimizing costs associated with storage, maintenance and repairs. Ultimately, these innovations ensure that end users realize the greatest value for the long-term.

Maroussis: Storage is critical for any businesses’ security and after-the-fact coverage, and it’s one of the most costly considerations to any integrator and their clients. Luckily, with edge recording, trickling and growing Video Surveillance-as-a-Service and the Cloud - like our Stratocast system with Microsoft Windows Azure - storage options have gotten so much broader. The new storage and capacities with read /write controller, virtualization all have increased in performance and will continue to decrease in price.

SIW: Where will we see camera innovation come from over the next several years?
