34 Security Dealer & Integrator / May 2018 s with many new technol- ogies, it is oen difficult to immediately ascer- tain its best fit in the security landscape. Such is the case with H.265 cameras. Systems integrators everywhere are struggling to counsel customers on the best approach for taking advantage of the new technology. ese new-to-market models can reduce file size by half without compro- mising video quality, saving customers money on storage hardware and net- work infrastructure. At the same time, displaying and processing H.265 video requires far greater horsepower, which can add to system costs elsewhere. Balancing a range of considerations is essential to providing meaningful guidance. Here's where to start: New vs. Legacy Perhaps the biggest factor that will determine the net benefit of H.265 cameras, for any given project, is whether they will be part of a new sys- How to Design H.265 Systems A closer look at how the new technology will impact legacy systems, VMS, file sizes, display, analytics and more By Guy Azari Video Surveillance A tem or if they are being incorporated into an existing installation. Greenfield: For new installations, all hardware should be specified based on H.265 processing requirements. VMS manufacturers who support H.265 by providing separate hardware specs for the new standard are begin- ning to emerge. Customers purchas- ing such workstations and servers will initially pay more, but over time, this will be countered by savings in band- width and storage. While it is not yet, in the foresee- able future, H.265 will become the default standard – thus, it would be short-sighted for customers to try sav- ing money by purchasing new hard- ware incapable of supporting it. Either they pay for it once, now, or they will find themselves paying twice when they need to upgrade down the road. Plus, with appropriate hardware in place, the use of H.265 cam- eras throughout an installation can greatly enhance system perfor- mance and value. Legacy: For customers who already have a functional VMS network and are looking to add new H.265 cameras or swap out older cameras for H.265, the equation is more muddled. In these cases, a project that is budgeted for just new cameras can open a can of worms when it is determined that the new cam- eras compromise the performance of existing display stations and other func- tions, like search and video analytics. In some cases, it may make sense to stick with H.264 for the time being, especially for systems using older PCs for monitoring purposes. Almost all H.265 cameras can also support the H.264 standard, so for- ward-thinking customers may still find it wise to invest in H.265 models as they add to their network, even if the cam- eras' superior encoding capabilities won't be put to use until some later date. The Impact of File Size In terms of overall efficiency, H.265 is just like H.264, in that it performs the very best in situations where there is
