As you may have read, I can be a little harsh – well very harsh really – on products where the market perception of what they can do does not match the reality. I did this in an earlier article but am coming back to either confirm or dismiss those claims by doing some first hand […]
Is a 360 Degree Camera any good for security?
Can a 360 degree camera do the job of several other security cameras? Here are some of the issues that need to be considered before you decide.
Do More Megapixels Give Better Results
There is much more to consider when selecting a camera than how many megapixels it is. One of the key points made is the compression engine used Indeed, many see the term ‘megapixel’ as a reassurance of high quality, but this isn’t the case. If, for example, you had 1.3 million pixels of poorly processed […]
That’s how you do it! Put cameras in the right locations
If more training was provided to sales and the CCTV installer, we might find the images are more like this & the conviction rate would increase greatly.
How Many Megapixels does a CCTV Design need for Identification
With megapixel surveillance cameras being available in a broad selection of resolutions, how do you know how much is enough? Many salespeople are making huge recommendations as to what to expect from a megapixel camera as an upgrade from a analogue 4CIF camera. Things like 1 camera will replace 5 cameras or even more just […]
Surveillance Camera Comparison Parameters
To compare various surveillance cameras in 3D drawing software we need a set of constants to begin with. Being from Australia, I am working to the standard AS4806 for the base definitions or resolution criteria. All the examples use here are created using Video CAD Pro but similar results can be obtained with the JVSG […]
Assessment of a 10 Megapixel surveillance camera image
With manufactures continuing to release larger megapixel surveillance cameras for applications in CCTV, are we actually getting an improvement in image quality or just bigger files to manage? If you search around the CCTV sites on the internet, you can easily find examples of real world performance of different IP cameras. Today I am looking […]
Mount the camera low enough to see faces
Often cameras are installed at a height that prevents them being touched. Unfortunately this is too high in many cases to see faces. Particularly if the person is wearing a hat. If the camera is intended to give facial identification, the vertical angle (from the horizon) should be small enough that you are looking into […]
Understand what the camera is for. Bigger Mega Pixel’s is not always better.
When you install a camera, the most likely mistake will be expecting too much from it. Cameras have improved dramatically with their light performance, resolution and back light compensation. However they still have limitations that are often ignored until after you have had an incident and cant identify anyone. The requirement of the camera needs […]
