Sony sets the groundwork for implementing a video surveillance system

In this article, Sony assesses which technologies best respond to video surveillance environments and how it has applied this to its security solutions.

Sony She has been dedicated to the surveillance industry for almost three decades. It manufactures its own sensors and incorporates technologies into its solutions that mitigate certain factors that influence when it comes to optimally securing an environment, such as poor lighting, The backlight, changes in the light level or camera shake. Parameters that can be compensated through the camera's digital image processing.

The design of your video surveillance systems also takes into account the task for which they are to be used, that should work 24×7 and they will be set up in locations prone to vandalism.

If the camera's image sensor chip doesn't capture your subject, the opportunity to portray him is lost. The sensor is responsible for the sensitivity that allows you to see in low-light environments, The resolution to capture the details, frame rate to capture moving subjects at the decisive moment and colour to register identifying information.

Sony is the leading manufacturer of image sensors internationally. Its sensors are found in all kinds of products, from webcams and smartphones to high-end DSLR cameras and sophisticated digital cinema cameras. Its Exmor CMOS sensors combine low-light capability with minimal noise, High resolution and a high frame rate.

Ipela Engine

The person who coined the term 'circumstances beyond our control' had to be a surveillance professional. A wide variety of viewing obstacles can infiltrate the scenes you want to monitor. Poor lighting, The backlight, Changes in light level or camera shake can prevent optimal surveillance.

Although it is not always possible to control all these elements, Yes, they can be compensated with the camera's digital image processing.

Sony has applied its expertise with digital image processing to successive generations of Ipela Engine systems, Ipela Engine EX and Ipela Engine EX Pro. Ipela Engine systems encompass Depa analysis processes, In-camera image stabilization, High frame rates and its dynamic noise reduction eXcellent (XDNR).

The cornerstone of that solution is View-DR processing, A wide dynamic range technology (Wide-D) that doesn't sacrifice low-light performance. By capturing two or more exposures per frame, View-DR captures both highlights and shadows in optimal detail.

This technology can combine Full HD resolution with a dynamic range of up to 130 Db. This means that Sony's cameras are prepared to compensate for extreme backlighting, poor lighting and changes in the light level.

Vandal-proof security

Security cameras must work uninterruptedly 24 hours a day, 365 days a year, Even in the most challenging environments. This means that equipment that is in vandal-prone locations must be protected from intrusion, Entry and other damage.

Sony's vandal-proof cameras feature triple protection. Begin with, They are difficult to force, with screws inaccessible for common screwdrivers. Secondly, The outer domes have a protection that prevents access to foreign objects, according to IP66 international standard rating. Finally,, offer great resistance to brute force and shock.

The IEC International Standard 62262 recognizes resistance to a wide range of impacts, from IK00 (the lowest) up to IK10 (the highest). Sony's vandal-resistant cameras are included in the highest category: IK10. In addition to having physical barriers, they are also protected on the IP network by password-controlled access, SSL client authentication and wired port authentication 802,1 X.

Cheap can be expensive

For some users, The most important specification is the price, But cameras that at first seem like a 'bargain' can be quite expensive in the long run. If a camera is not capable of producing usable images, that allow for the clear identification of bad practices, The potential cost can be catastrophic.

Trying to save without understanding what your real needs are is a typical beginner's mistake. So is focusing on a single specification rather than considering overall performance.

Each application has its own resolution requirements, Low-light capability, Frame rate and backlight treatment. That's why it's worth betting on an experienced security designer and installer, someone who knows where money can be saved and where not.

The Value of Spec Sheets

While spec sheets have their place, Not all manufacturers are equally informative and not all specification comparisons are meaningful. Even when all the specs are published and all the comparisons are realistic, Important differences can go unnoticed.

For example, spec sheets rarely deal with color reproduction, specifically the visibility of colors in low-light environments. Color perception is very subjective, so it is much more useful to see it than to assign numbers to it.

The specifications also don't describe how quickly the cameras adapt and stabilize when the lighting in the scene suddenly changes, like when someone turns the lights in the room on or off. They also don't reflect how the camera's noise reduction behaves when moving objects are present. To check all these aspects, You need to see the camera in operation.
