In order to better understand and identify activities, events and people, recording quality has increased. 4K offers four times the resolution of 1080p HDTV. This added resolution can drastically improve the technology’s ability to identify crucial details in the camera’s field of view such as a person or a vehicle’s license plate. Implementing 4K video in a security camera system requires more storage capacity which is of better quality.
The surveillance industry is transitioning from analog to digital at a rapid pace. These changes are having a direct effect on how video storage is chosen and managed.
Increasing detail, resolution and quality
In order to better understand and identify activities, events and people, recording quality has increased. 4K offers four times the resolution of 1080p HDTV. This added resolution can drastically improve the technology's ability to identify crucial details in the camera's field of view such as a person or a vehicle's license plate. Implementing 4K video in a security camera system requires more storage capacity which is of better quality.
Increasing Frame Rates
Capturing and tracking details in real time is crucial in a surveillance solution. From a frame every few seconds, to 5fps or 10fps, is now 24fps, 30fps and more. Although codec efficiency helps alleviate the impact of increases, each step up requires additional storage capacity.
Always on surveillance
Security never rests, so surveillance needs to be ready to record the instant something happens. Constant recording in sensitive areas and motion detection needs fast and reliable storage.
Audio recording and fidelity
Audio is an increasingly important element for video surveillance. Cameras are now even closer to the action – in locations such as major retailers or warehouses it's useful to make out conversations or sounds surrounding events, to identify people, vehicles and the environment. All of these things can be analysed even when out of camera shot. The storage system needs to accurately capture sounds and in sync with video.
The increase of interactivity
The increasing demands of recording video feeds needs to be balanced against the need to access and process historical data. Facial recognition, number plate recognition or object detection over time enable companies to recreate a journey or trace access or proximity to facilities. Multi-feed access, fast replay, slow-motion playback and seamless zoom and enhancement are required for analysis. A storage system that stutters can lead to long and unnecessary delays.
When every second counts in surveillance, reliability, dependency and the cost of operations require the best storage products for the solution. WD Purple and WD Purple NV are surveillance class hard drives designed for high temperatures, always-on, surveillance security systems to ensure reliability and quality video play back when people need it most. Available in up to 6TB capacities and with exclusive IntelliSeek technology, WD Purple drives calculate the optimum seek speeds which lowers power consumption, noise and vibration that can damage and cause desktop drives to wear out more quickly. These surveillance-class hard drives are also equipped with AllFrame technology which works with ATA streaming to reduce frame loss, improve playback and increase the number of drive bays which it supports. AllFrame reduces video interruptions that commonly occur when desktop hard drives are incorrectly used as storage in security systems. Missing frames and lost footage is a serious problem when an event occurs and surveillance footage needs to be retrieved. WD Purple with AllFrame provides the confidence companies should expect when it's time to play back and review critical surveillance footage.
