Combining a body camera with a remote speaker microphone, our body worn cameras can capture, store and share video audio in the field. The multi-functional design can reduce your equipment costs and simplify communications whilst helping to create a safer environment for your employees.

The term “diverging mirror” is based on this mirror’s behavior of making rays diverge upon reflection. So when you direct a beam of light on a convex mirror, the mirror will allow the initially parallel rays that make up the beam to diverge after striking the reflective surface.

The same kind of security devices are installed on automated teller machines to give the person withdrawing a good view of what is happening behind him. Some cell phones are also equipped with these mirrors to aid users when performing a self portrait shot.

Easily find data by tagging an evidence file to access it later via a keyword search. For extra data security, customised permissions can be managed for different users.

For many years body cameras have been proven to deter aggression and provide an independent account of incidents for blue light workers such as the police, ambulance workers and firefighters to enforce the law and for safety.

Since convex mirrors have wider fields of view than other reflective surfaces, such as plane mirrors or concave mirrors, they are commonly used in automobile side mirrors. Having a fish eye on your automobile will allow you to see more of your rear.

Securely store and manage all your digital evidence. Save time and share your evidence quickly and efficiently via an access link.

Our body worn cameras support push-to-talk over cellular (PoC) voice communications. By simply pressing the push-to-talk key, the user is able to make both individual and group voice calls. With advanced noise reduction technology, the camera picks up the user’s voice whilst filtering out the ambient noise, allowing for loud and clear audio, even in noisy environments.

But it’s not just law enforcement who face situations where body cameras can make a difference. NHS frontline workers, care workers, teachers and retail staff are also regularly in situations where they face disruption or aggression.

A convex mirror is a spherical reflecting surface (or any reflecting surface fashioned into a portion of a sphere) in which its bulging side faces the source of light. Automobile enthusiasts often call it a fish eye mirror while other physics texts refer to it as a diverging mirror.

Share real-time, high definition video with centralised teams so they can see exactly what is happening and enhance situational awareness. When the emergency button is pressed, the camera will automatically start recording, and immediately trigger the emergency alarm to the control centre. Pre and post recording video buffer captures events for up to 30 seconds before/after the user turns the video recording on/off.

Many frontline workers who engage with the public frequently face confrontational behaviour or disputes from the public.

Evidence management is an integral part of any body worn video solution. Our evidence management platform collects and securely stores high definition digital evidence from the body worn cameras, that can be reviewed, managed and shared quickly and efficiently.

Unlike images formed by concave mirrors, an image formed by a convex mirror cannot be projected on a screen. Such an image is called a virtual image. If one is to visualize the location of such a virtual image, then the image is found behind the surface of the mirror.

Data is automatically uploaded to the cloud, and can be remotely accessed by users wherever they are. As a standalone solution connected to the cloud, there is no need for network connectivity, and no excessive data charges.

Want to see an object that is both a convex and a concave mirror? Take out a metallic spoon – the inner side is a concave mirror while the outer side is a convex mirror. Notice how your reflection is diminished in size. You may compare that with your reflection on a typical wall-mounted mirror.

Staying connected anywhere, anytime is crucial for some businesses. With our body worn cameras, you are able to leverage messaging, audio and video communication.

The complete description of an image formed by a convex mirror is: virtual, diminished in size, and upright. When we say upright, we mean that if you position an arrow in front of this kind of reflecting surface, then the arrowhead of the reflection will point to the same direction as that of the object (the real arrow) itself.

Providing staff with body worn cameras can help diffuse situations, allow businesses to react faster in an emergency, record key events exactly as they took place and supplement other video, audio and eyewitness records.

Body worn cameras are proven to reduce conflict, improve personal safety and help secure criminal prosecutions by providing encrypted and tamper-proof video and evidence.

A convex mirror is also a good security device. Store owners, for instance, install a number of them inside their stores and orient them in such a way that a single security personnel can see large portions of the store even while monitoring from a single location. They are the large disk-like reflective surfaces that you see near the ceilings of grocery or convenience shops.
