- Conduct national and international CCTV Seminars based on our four best-selling books.
- Perform testing and analysis of IP and CCTV products, and provide reports, as neccessary.
- Offer specialised test methods and tools to help evaluate analogue and digital imaging and CCTV systems quality.
- Assist Standards organisations and bodies in their developing of standards.
- Long experience and know-how in designing CCTV systems and preparing documentaion.
- Fluent with using professional drawing tools and 3D modelling for various documentation.
- Sound knowledge in graphic design and life-long experience in optics and Photography.

NEW !!!
We have just designed a special ViDiLabs calculator for iOS.
Specifically designed for the IP CCTV industry, it calculates all variables associated with finding the best camera and lens combination for your coverage.

It advises the pixel density for Face Inspection, Identification and Recognition as per the standards.

For the first time ever in the industry, it also calculates the blurriness that moving objects produce and advises the best exposure setting, lens and distance to minimase this effect.

We have also included storage calculator and image quality indicator, based on our SD/HD test chart.

Watch short tutorial explaining the Visual part, the calculation of Motion blur, and explaining the Digital part about storage and image quality.

World first CCTV SD & HD test chart in one!

This chart is designed for both Analogue SD cameras, as well as HD and
Megapixel cameras (A$500+shipping).
Download the Setup and Usage manual here.

We use 3D rendering software to show scaled model of the precise coverage of cameras in a CCTV System design, including the calculated Pixel Density at all distances. This gives the customer very accurate representation of the proposed system coverage and its clarity. In these calculations we use our ViDiLabs calc app. To download and see a 3D rendered movie of a stadium coverage click here.

There are four test chart snap-shots from four different lenses shown on the left.

For obvious reasons there are no lens manufacturer's names mentioned.

All lenses are claimed to be mega-pixel lenses.

The same camera is used throughout and all camera settings are identical. The angle of view, compression settings and illumination are also identical.

All lenses are focused for best possible image.

Even though the exported images are reduced and cropped (for the purposes of displaying on the web site) the image quality is obviously different, the top one being the best, and lowest being the worst.

All lenses are vari-focal, mega-pixel and within a similar price range.

Lens quality may be one of the most important factors in obtaining the best possible image for your cameras.

The ViDi Labs test chart is one of the easiest and optimal methods for objective comparison and testing.

Using the ViDi Labs SD/HD test chart it is possible to test and measure the effect of fast moving objects on the resulting recorded video.

With this new and unique method we have advised this process, and offered some formulas that will help in determining such pixel shifting, while taking into account all the possible variables.

We used the same formula to calculate pixel blurriness due to moving objects in the ViDiLabs Calc.

The test example on the left illustrates the appearance of movement (in this case oscillating test chart) and shows the accuracy of the developed formula above.

While we work and do our testing with many different Surveillance and VMS software, most of them are designed for Microsoft Windows.
In our work we use Mac OSX for all our designs, measurements, drawings and image analysis. When using Windows based software, we work in BootCamp mode of Mac OS X, which accesses all of the Mac designed hardware, including the Intel CPU, with native Windows OS.
Very rarely we come across surveillance software that is designed to work with Mac OS X.
One such software is the Security Spy by Ben Software, and here we would like to recommend it to all Mac users.
