We believe in deterring crime before it happens, rather than trying to verify the crime that has happened. Using modern AI capabilities, high quality cameras, fast internet connections and our world-class control centre – we are able to achieve this.

How to get started
OmniVision is constantly scanning the ever-changing technology landscape looking for the latest and greatest products for our clients. Currently, the most effective video detection systems we use employ artificial intelligence (A.I.) to greatly reduce the number of false alarms while simultaneously increasing the accuracy of detection.

In the context of security, A.I. brings huge potential and has the power to transform performance. However, it is not (yet) a replacement for human evaluation and existing processes. Even with the improvements being made, security professionals shouldn’t look to artificial intelligence as a full solution, rather it is an extension and enhancement to our current operations.
A.I. has already proven itself as an excellent technology for false alarm reduction, eliminating more than 85% of the false alarms generated by previous systems while also increasing the percentage of positively identified threats. Partnering only with the best internationally recognised names in machine learning and A.I.,
Any technique that enables computers to mimic human intelligence can be classified as “artificial intelligence”. Techniques employed to mimic human intelligence can include logical rules, if-then rules, decision trees and machine learning. The most effective modern systems use machine learning, and often include the sub-set of machine learning called deep learning. But what do these terms actually mean?
Artificial Intelligence: Any technique that enables a computer to mimic some aspect(s) of human intelligence. Includes the use of if-then rules, logic, decision trees and machine learning.
Machine learning: A subset of A.I. that uses statistical techniques that enables machines to execute tasks without explicit instruction, using patterns and inference instead. Machine learning enables a computer to improve at tasks with experience.
Deep learning: A subset of machine learning that utilises multi-layered neural networks, permitting software to train itself and improve its performance on tasks, like speech and image recognition, through exposure to vast amounts of data.
Machine learning is best suited to tasks that have a lot of data, where each instance of the task is similar to the others and where each task has a clearly defined objective input and output – as is the case with human detection on video.
With machine learning, a set of parameters is applied to a given input to produce a desired output. At each learning step, the error between what the model produces and what the correct answer is gets measured. The parameters are then updated with respect to this error so that on the next try, the error should be smaller. Over a multitude of iterations, a high degree of accuracy can be achieved.
The single largest limiting factor in the use of A.I. is the amount of data required to get an accurate, useful system – it is very data hungry! Without this data to learn from, it performs extremely poorly. Additionally, as deep learning models get more complex, they often take longer to train, so it can take longer to see performance gains or ever more resources are required to achieve the same result.
This is a very important consideration when choosing an A.I. provider, to ensure you get the best system/result, you need to ensure your partner is adequately resourced!
Another limitation is that it is very difficult to know why a deep learning system has made the decision it made. This has slowed down their adoption in areas where interpretability is important, such as medicine and credit scoring.
There is ongoing research in order to improve the efficiency and effectiveness of machine learning techniques and the field is constantly evolving. Areas of research include:
How to reduce the amount of data required to train a deep learning model and how to speed up the learning process. Additionally, better graphical processing units (GPUs) allow for constant improvements in the number of calculations that can be done in the same amount of time.
Immediately the alert will be assessed by our experienced control centre staff, whilst they view realtime and a recording of recent events simultaneously.
The operator will make a decision whether to use an audio broadcast on-site to challenge the threat and/or communicate with armed responders or police to attend.
In cases where an alert is deemed to be a potential threat, a notification is also then sent to your nominated contacts via WhatsApp with an image of the threat. In serious cases requiring armed responders or police, a full report of the incident is issued to you via email afterwards.
Omnivision is an off-site CCTV monitoring company, and does not provide an armed response service.
We require customers to provide us with first responders that we would contact if a threat is determined, which is typically your armed response company. Our control room can dispatch your on-site guards at estates and businesses, where they are available. In cases where the customer is part of an estate or community deployment, neighbourhood watch responders can be contacted. We’re also able to contact the police where required.
First, you’re going to need cameras. Omnivision do not install cameras, megaphones or related equipment – but are able to refer you to trusted installers in your area. Please click the button below to download a list.
If you have cameras already installed, then these can often be used. Please click to request a quote and we can survey and advise further.
Your next step is to request a quote from us, and our sales team will be in contact to get started. It is a quick and simple process to activate Omnivision monitoring.
Locations where we can help include businesses, estates & communities, homes and farms across South Africa.
