Viewing Angles - Varifocal Lenses
You can change the viewing angle of a camera to make distant objects appear closer, to zoom in.
Using the image below, left, see that little black car in the top left corner, whats the registration number? The number plate is too small to read even when zoomed in.
A varifocal lens lets you set the camera viewing angle from wide (92 degrees) to a narrow view (23 degrees) and anywhere in between.
Doing this brings distant objects closer and therefore makes them clearer.
In the image on the right the little black car is shown with the camera lens zoomed in. You can now read the number plate, but at the cost of the wide angle view.
This is why a varifocal lens is best so you can set the best viewing angle for each location, not too wide and not too narrow.
View cameras on your TV or Computer monitorThere are several ways to get the recorder and cameras showing onto your television screens or a spare computer monitor. If the recorder is located close to the TV you can use a standard HDMI cable or a VGA computer cable to connect TV/monitor to the recorder If the recorder is not located close to the TV you could use extra long cables and a remote mouse for recorder control. Alternatively, if you have a Smart TV that uses the Android operating system you can download the app to the TV, or use a cheap Android box with the app.
Can I remotely access the cameras with my smartphone?

All our cameras have on-board IR LEDs which enable them to provide clear black and white images when it goes dark. Our cameras have between up to 180 metres Night vision range - we think that's pretty impressive. Have a look at a few night snapshots below taken using our cameras:
Starlight technology is the gold standard in low light video performance. It provides clear and relevant images regardless of lighting conditions, time-of-day or object movement. Our cameras that feature Starlight technology can deliver detailed monochrome images where other cameras show no image at all, substantially improving levels of security.
Both HD 1080P and 5 Megapixel Systems are clear enough for facial recognition - View the video below for actual 4MP footage from our cameras.
NPR - Number Plate Recognition
During the daytime it is not a major problem to read number plates, all you need to do is set up a camera to capture the plate, make the number plate as large as possible on screen and it will capture it, if the camera viewing angle is too wide the number plate will be too small and will not be readable.
Night time number plates is a different story… what happens is the Infra Red light that the camera gives out bounces back off the plastic plate and shows on screen as a white glowing rectangle. This is why on motorways where there are cameras there are lights.
There are specialised number plate cameras available but these are costly and more importantly they are only useful for capturing number plates, they achieve the number plate capture by dimming down the whole picture by closing the iris so much that the plate becomes readable, but this darkened picture makes them useless as a general purpose security camera.
The best solution for capturing number plates at night is a three point method… light it up, slow it down and zoom it in. Light up the car with a security light, this switches the camera to daytime mode, slow the car down with traffic calming methods to reduce image blur as much as possible and zoom it in, make sure the number plate fills a significant portion of the overall screen, doing all three of these will capture number plates, doing any less than the three things will reduce the chances of capturing a plate 100% of the time.
