Good security is a good business practice. Stores, medical clinics, service stations, restaurants, banks, credit unions, libraries, parking lots, and other public areas all benefit from video surveillance as a crime deterrent and evidence when an event occurs.
Digital security surveillance (DSS) solutions using IP cameras and network video recorders (NVRs) have radically improved video surveillance. Today’s DSS solutions offer the following advantages:
- Image quality. IP cameras provide superior evidence. Their high quality images make it possible to zoom in with much less loss of detail than analog cameras, increasing the video’s value for applications ranging from retail fraud (monitoring point-of-sale) to license plate recognition.
- Open platform solutions. Intel® processor-based platforms for NVRs enable a wide choice of software, cameras, servers, monitors, and other components instead of being locked into a single supplier. Greater choice leads to greater competition in pricing and features.
- Hybrid systems. Businesses with analog cameras don’t have to switch all at once. Hybrid NVRs can handle both types of cameras. What’s more, analog-to-digital encoders enable connecting analog cameras to standard NVRs.
- Inexpensive storage. The shrinking costs and increasing capacity of today’s hard drives makes them ideal for video storage. Video management software (VMS) running on NVRs improves storage reliability and access to video files. Video can be easily transferred over the Internet to the cloud or other offsite resources for archiving. Digital video is also easier to edit and forward to law enforcement agencies or other entities.
- Video analytics. Using video analytics software to automatically scan footage, identify certain trigger events, and issue alerts reduces reliance on live viewing. Analytics solutions are available that can identify shelf sweeping motions consistent with shoplifting, loitering in parking lots or building perimeters, and other suspicious activities.
Network Video Recorders (NVRs)
Small business DSS solutions involving multiple cameras need a NVR to collect, process, and store the video (Figure 1). The NVR may be connected directly to a monitor to enable live viewing, as well as searches of already processed and stored video. With many NVRs, live and stored videos can also be viewed remotely over the web using a desktop PC, laptop, tablet, or even a smart phone.

NVRs powered by Intel processors can benefit from powerful integrated HD graphics capabilities. The 4th and 5th generation Intel® Core™ i5/i7 processors and the Intel® Xeon processors E3-1200 v3 product family include on-chip graphics that eliminate the need and expanse of a discrete graphics card. The onboard Intel® Quick Sync Video provides hardware-accelerated decode, encode, and transcode, delivering fast processing of up to 20 or more simultaneous streams of video. The processors also connect to and independently display on up to three monitors at resolutions up to 4K.
For video processing and analytics performance, these processors include Intel® Advanced Vector Extensions 2 (Intel® AVX2). Intel AVX2 is a 256-bit instruction set extension designed for floating point-intensive applications like video processing and analytics. It improves performance by enabling wider vectors, new extensible syntax, and rich functionality. The result is improved data management and performance in image processing, audio and video processing, and analytics.
