Is your video solution integrated into security cameras??

The development of integrated solutions in video surveillance cameras and their contribution to create sustainable innovative systems focus this analysis of Uri Guterman, director of product and marketing of Hanwha Techwin Europe.

In the days when there was only analog CCTV, a local video recorder with videotapes would have been needed. (VCR) to retain evidence captured by security cameras. This required the purchase of a large number of videotapes to ensure that the images could be stored for thirty days or more., as each tape had a limited capacity.

Organizations with multiple sites could also choose to remotely monitor images transmitted over the public switched telephone network, ASDL or expensive dedicated lines, rented to a central control room.

With the arrival of the video surveillance based on IP networks, users had the option to conveniently store large amounts of video data on an IP video recorder (Nvr) or server, and one of its main advantages was that the network did not collapse by transmitting video sequences of scenes in which nothing important happened.

As a result, The event-driven monitoring, which is also known as an exception report, became an accepted method of drawing the attention of control room operators to an incident. If necessary, they could also recover, quickly and easily, pre- and post-event images of the incident.

The benefit of this became even more apparent with the introduction of multi-megapixel cameras, when there was a need for captured video data to share available bandwidth with other data being transmitted over the network.

No doubt, many security officers will have received the comment “don't even think about it!!” of your organization's IT department, that he was not prepared to run the risk of being interrupted transmission of critical data company.

Although it is likely that most of the large video surveillance systems installed in recent years use network resources that are already separate from the main infrastructure of a company, the opportunity to minimize bandwidth requirements and associated costs remain a major benefit.

Processing power

However, a manufacturer was needed to lead the way by developing a chipset with sufficient processing power, and allow data to be recorded and stored in SD cards built into cameras, instead of more expensively on an NVR or server.

Cameras with dual SD card slots, which together offer a capacity of storage up to 512 Gb, can give security personnel the peace of mind of knowing that what may be crucial evidence will be safely stored in the camera itself..

At maximum frame rate, images continuously captured by high-definition cameras 2 Mp, For example, will be stored for up to approximately twenty days before they are deleted with new recordings.

The number of days of recording can be increased if a lower frame rate is accepted and/or if a manufacturer has developed its own compression technology that complements H.265 And, in doing so, minimize storage requirements and improve bandwidth efficiency.

SD cards will also help keep data safe in the camera in case of data network outage. The implementation of cameras with backup of automatic recovery (Arb) ensure that the activity recorded on an SD card, in case of temporarily losing a connection, automatically transmits to a remote recording device when connection is restored.

Embedded applications

Video surveillance cameras are increasingly considered as smart computing devices, equipped with an image sensor and a lens.

In this sense, we are approaching the moment when the excellent quality of the images captured with multi-megapixel cameras will be taken for granted, in the same way that we now consider that we can make calls from a mobile phone.

For example, when was the last time you saw an ad promoting the functionality or call quality of a new mobile phone??

A lot more can be done with cameras now that they have the ability to run apps with built-in video analytics, As heat maps, people count And queue management, as well as pandemic-related solutions, such as mask detection, distance measurement physics and occupancy monitoring.

With the processing power to do so, it makes sense to extract the information captured in the camera itself and thus avoid transmitting large amounts of data over the network.

While manufacturers like Hanwha Techwin they already supply preloaded cameras with these applications, as well as intelligent video analytics (Vat) for tamper detection, Directional, blur and motion, Etc; the option to embed analytics offers the perfect opportunity for third-party software developers to innovate on serverless solutions that meet the specific needs of vertical markets.

Economical and scalable solutions

As an example, there is an automatic serverless license plate reading solution for ‘small installations’ that automatically controls the access of cars, whitelisted, through barriers, using the camera relay outputs, in addition to giving valuable information about parking management, as the 'time spent'’ and occupancy rates.

this is done without users having to incur the cost of installing and running the application on a server, as up to four cameras (one teacher and three slaves) can simultaneously capture and transmit video analysis data to a convenient user interface.

The solutions embedded in the camera itself, serverless, are scalable and, therefore, give users the flexibility to gradually expand their systems at any time, without having to purchase an expensive server.

Video analytics based on 'deep learning'’

These applications improve video surveillance, that goes from being just a security system that helps monitor and detect suspicious activity, to become a smart solution with more possibilities.

The recent introduction of affordable cameras that have video analytics with artificial intelligence based on deep learning (deep learning) has further improved its ability to be used as detection devices.

Video analytics with AI based on deep learning ignores video noise, the leaves of trees moving, clouds moving and animals.

All of this could be the cause of false alarms when sensors or standard motion detection technology are used to detect activity., as they have not been designed for that purpose.

This higher level of performance of video analytics with artificial intelligence based on Deep Learning means that control room operators and security personnel can focus on responding to real incidents and emergencies and not waste time and effort on false alarms.

In addition to extreme precision, deep learning it also allows operators to search for specific features and attributes, including a person's age group and sex, if you are wearing glasses, hat or a purse.

Retail and Traffic Applications

Cameras that have artificial intelligence with deep learning are particularly suitable for applications that require a higher degree of sophistication than traditional video analytics offers.

For example, enables businesses to capture and apply business intelligence for people's age and gender, making it easy to analyze customer demographics individually and, in doing so, gain a greater understanding of your buying behavior and patterns.

Road planners, traffic enforcement authorities and police can now leverage AI-based cameras to identify the brand, the model and colour of the vehicles, in addition to recognizing the license plates of cars.

The Intelligent Traffic Management Solution Wisenet Road AI integrated into the camera, to be presented to the market soon, use video analytics with artificial intelligence based on deep learning to identify more than seven hundred models of vehicles manufactured under seventy brands.

Data can be used to conduct studies and gain a greater understanding of road use, as well as to help accurately identify vehicles involved in traffic violations.

System integrators will find that solutions embedded in the chamber itself offer the opportunity to provide their customers with innovative and sustainable systems.. For example, autonomous smart devices that could even work with solar panels.
