Recently while driving a rental I discovered some interesting autonomous safety features, such as lane assist and warnings when you do not hold a steering wheel properly, but the spontaneous unexpected self braking got me the best.
Technology has been entrenched in our lives for a while. There are some we know about, and a lot that we did not realize are there. Of those that we know about, are we using that technology effectively and correctly.
In our security universe, we so often see the word AI and have a certain amount of expectations on its ability. A classic point in case is the ability of the Hikvision recorder to detect motion and then classify it as general, human or automotive.
These are features that are generally available in many products,and it helps to narrow down on the ‘false alarms’ or probably a better term is Unwanted Alarms. This means that we would only be concerned with notification of humans or vehicles in a demarcated area as opposed to plant and vegetation movements, clouds causing shadows, or wind blowing sand over a smooth surface.
This is often what a customer with a large client database requires to bring a higher level of efficiency to their monitoring company. Movements are received from cameras on a site, and the recorder in turn re-analyses the movement information and then makes the decision as to raising an alert.
All is well and fine except that we often interpret AI as infallible and independent. It is supposed to be self learning and perfectly carry out functions without involvement.
Realistically all technology has limits, specific applications and boundaries.
Coming back to our video analysis, there is undoubtedly a responsibility from users and consultants to match situational requirements with device performance.
The function of the NVR is to re analyse video, but there are the limits of excessive data or complex scenes, so do plan projects carefully from multiple angles. It is after understanding the particular environment and the requirement that one is able to avoid random choices and provide advice.
- How many people or vehicles move through the area.
- How much other motion are we needing to exclude.
- How often will this motion happen.
- What percentage of the area has this ongoing motion.
- How many cameras on the NVR need to have their video assessed.
- What is the security level required for the environment.
- What is the load capacity and capability of the monitoring centre.
- What budget is available.
- Are there POPI restrictions.
Avoid walking into the disappointment of failing designs but correctly and fully discussing projects with a consultant.
