dent are uploaded into the search analytic tool. Analytics are run to identify and classify objects and record their properties. Later the investigator can filter the video based on object type and properties. If the investigator wanted to find all trucks, moving from left to right in the scene, at a certain rate of speed and which are green in color, the search analytics can now query its database of objects and properties and call up video from the time matching objects were detected. This makes the review process dramatically faster, but has other benefits as well. During a lengthy review process, investigators can become fatigued and lose focus, potentially missing key details. Introducing search analytics reduces the likelihood of missing key video evidence.
As with facial recognition, search analytics require substantial computational power. The amount of computational power available directly impacts the processing time, which can mean the difference between getting results within an hour of the incident or a day later, after video has processed. In situations where search analytics get heavy use, or when time is of the essence, the hardware can add sub- stantially to the overall search analytics solution cost.
Also, with facial recognition, search analytics have benefited from co-processing technologies such as GPU or FPGA based co-process- ing integration. Such co-processing technologies allow a relatively in- expensive co-processing card to be added to a server platform which dramatically increases the speed of the analytics software running. It is of note that co-processing technologies cannot be used with any software package. Software needs to be written specifically to inte- grate with a co-processing technology, so work with the software ven- dor on the best hardware design.
Product Country of Origin
A recent trend with major influence on product selection, especially
security cameras, is the country of origin of the manufactured equip- ment. This year, several factors have influenced the renewed focus on equipment country of origin, including:
• Media within and outside the security industry has written on the
influx of cameras developed in nations not traditionally consid-
ered to be allied with western nations.
• The United States has imposed tariffs on some imported equip-
ment from certain regions.
• The United States has signed into law the National Defense Au-
thorization Act for 2019, which specifically calls out by name par- ticular camera manufacturer’s equipment which cannot be sold to U.S. government entities.
As such, buyers within and outside government organizations are
taking a second look at where their security equipment comes from. Camera providers negatively impacted by these trends generally provide lower cost products. Another impact as a result of this trend
which we may see will be reduced pricing pressure on other brands.
The Takeaway
Whether one is in the planning stages of implementing a video security system, has an existing installation or is in the process of an upgrade, being mindful of near-future trends in the industry can help guide ex- penditures and plan infrastructure builds. With the proliferation of more accessible analytics-capable hardware, facial
recognition should increasingly factor in to video security system builds. In addition, current politi- cal realities may affect brand choices, and impact camera hardware costs for future deployments.
