48 Security Business / www.SecurityInfoWatch.com / March 2019 While cost obviously plays a role in choosing the components of a security system, the potential consequences of lost video frames or drive failure usually means the lowest-priced storage solutions can ultimately turn out to be expen- sive in terms of liability, legal and other ramifications. us, it makes sense for integrators to consider surveillance-optimized storage with health-monitoring capabilities. Video Loss and its Potential Consequences Given the increased importance of video for both security and operational purposes, losing even a few frames of video is simply not an option; how- Video Surveillance Video surveillance is a write-intensive application, often with around-the-clock workloads, which are extremely taxing on hard drives. ever, this is precisely what can happen when a hard drive fails. Any lost video creates a void, and the information it contains – which could prove very valuable – is lost forever. In this case, the cost to an organiza- tion could be staggering. For example, a company required to supply video to demonstrate compliance with regula- tions could face hey fines, sanctions, loss of licenses, or even closure. Other potential consequences include loss of reputation, financial loss or even com- plete business failure. Hard drive failure also impacts integrators, who are responsible for repairing and maintaining the solu- tions they install. Additionally, cus- tomers who face fallout from lost video may hold the integrator respon- sible, introducing potentially signifi- cant legal ramifications. Beyond these issues, lost video also means loss of any intelligence upon which an end-user relies upon to run their business more effectively, effi- ciently and profitably. In short, the negative impacts of lost video simply cannot be understated. The Case for Surveillance- Optimized Drives One of the best ways integrators can help insulate their customers from video loss and its consequences is by using surveillance-optimized drives. Purpose-built for video applications, these drives offer the features and functions necessary to provide the durability, performance and reliability customers require. Video surveillance is a write-in- tensive application, oen with around-the-clock workloads, which are extremely taxing on hard drives. erefore, storage solutions must be capable of keeping up with the demands of these applications to min- imize – if not eliminate – dropped video frames and system downtime. Unfortunately, it is oen tempt- ing to address customers' increased capacity requirements with lower-cost, moderate-capacity desktop drives for their video security systems. While controlling costs is a noble endeavor, this is hardly the best solution, and may actually end up being more expensive in the long run – whether from equipment failure, costs associ- ated with downtime or both. Meeting increased storage needs with limited-capacity solutions means installing more drives, which occupy more space and introduce more potential points of failure. With envi- ronmental factors playing a key role in drive longevity, the heat generated by a large number of drives is hardly conducive to providing uptime and reliability. On the other hand, sur- veillance-optimized drives have RV sensors that account for multi-bay environment vibration (which can sig- nificantly throw off performance even if it is minimal). In other words, sur- veillance drives are vibration tolerant for multi-bay environments, which is a distinguishing feature that separates these solutions from desktop drives. In addition to physical limitations, inexpensive desktop drives lack many of the features and functions necessary for optimizing today's video security systems. Most notably, desktop drives only operate eight hours a day, five days a week. ey are not designed to support large camera counts like sur- veillance-optimized drives. Features and Functionality e primary benefit of surveil- lance-optimized drives is their extremely high capacity, up to 14TB – which can enable months of 24x7 recording of high-quality video, depending on resolution, frame rates and compression. ese longer retention periods make video data more quickly and easily accessible for review and analysis. With more than four times the capacity of many low-cost desktop drives, surveillance-optimized solu- tions also enable end-users to easily deploy additional cameras to increase the coverage of their video system, upgrade to higher-resolution cameras or increase frame rates. In addition to higher capacity and performance, these drives also oper- ate with an extreme workload rating. Writing data can represent up to 90-95 percent of a drive's operation, and sur- veillance-specific solutions are opti-
