3 Benefits of Pulsed Lighting

Pulsed illumination offers several benefits that are well suited to transport applications. In this article we will look at three of these benefits in more detail. More Light The lifetime of an illuminator is controlled by the average operating temperature of an LED. Because pulsed illuminators are only turned on for a fraction of the total amount of available time (duty cycle), this means there is significant scope to increase the light output of an LED illuminator for shorter periods. Raytec pulsed illuminators typically provide 400% power output compared to... Read More

The Next Big Trend in Lighting Will Be…Hybrid Illuminators

The big trend in video surveillance lighting today is Network Illuminators. A move towards smarter network cameras has created a demand for smarter lighting that provides the correct amount of light for any situation and is capable of delivering the appropriate lighting response to any security event. The latest video surveillance systems require both good night-time images and connectivity between devices to deliver the best results. Since Raytec launched the first network illuminator in 2013, a technology that has now evolved into VARIO2 IP, fully addressable network lighting has been... Read More

Creating Smarter Systems with Network Lighting

Lighting has always been an essential component of high security video surveillance systems but has historically been treated as a stand-alone accessory. However, with the development of Network Lighting, it firmly places illumination at the very core of our security systems and unlocks more intelligence than ever before. It enables us to use lighting as an interactive and dynamic tool which can respond instantly to any situation at any time. IP Lighting can be fully automated to operate even if your site is unmanned. It can be triggered from any... Read More

How Raytec Calculate Illumination Angles?

The spread of light from your illuminator has a critical impact on the success of your video surveillance system. But in the absence of any accepted industry standards and testing methods the calculation of Width/Angle has historically been left open to the interpretation of the manufacturer – leading to varying performance claims. This has always made it virtually impossible for consultants, installers and end-users to specify surveillance lighting with confidence, reliably compare products, and achieve a consistent level of performance. Width/Angle Performance Consider the two images above, both manufacturers could... Read More

Take Live Control

All cameras need light to see during the hours of darkness. But with IP based security systems on the rise, it’s Network Lighting which not only helps us to generate good night time images, but which works with the entire IP system to help us stay connected to our site at all times. Being IP addressable, Network Lighting is designed to deliver the right amount of lighting exactly when and where you need it. Whether controlling it via its web interface, your VMS/BMS, or other platform integration, you have the... Read More

How Network Lighting Makes Set-Up & Commissioning Easier

Installation, setup and commissioning are made significantly easier for security professionals through the use of IP addressable network lighting. Gone are the days when we had to adjust illuminator settings in situ, often up a ladder or lift. With network lighting, installers now have quick access to configure all lighting settings via an integrated web interface from any remote network location. Adjusting the illumination had often been a time consuming part of any security installation and often involved a 2 person trip to site at night to achieve the best... Read More

Supercharge the Night-Time Performance of Your Bullet Camera

Bullet cameras offer a cost effective and compact solution for general surveillance applications and many also include integrated LEDs to deliver short range night-time images. But now with the latest developments in LED lighting, you can supercharge the performance of your bullet camera with even the smallest Raytec VARIO 2 illuminator and cover impressive distances at night. Despite their popularity, bullet cameras do have some significant disadvantages. Generally their night-time performance is limited to 15-20m. The in-built LEDs also don’t have the same heat management as dedicated external illuminators which... Read More

Identify in low light 25/04/2017

Achieve Outstanding Subject Identification at Night

The quality of your illumination is a critical factor in achieving good recognition and identification from your video surveillance system at night. Even low light cameras which can produce an acceptable overview of a scene in relatively low light conditions need dedicated surveillance lighting to identify a subject at night – especially when zooming in over long distances. LED surveillance lighting is the number 1 choice for empowering your maximum zoom function. It delivers targeted and powerful illumination exactly where it is needed so that your camera is able to...

Calculating Illumination Distances 24/04/2017

How We Calculate Our Illumination Distances

The security industry has historically suffered from a lack of any accepted standards for the measurement of illumination distances. Methods for measuring achievable distances have typically been left to the subjective interpretation of individual manufacturers without any scientific basis – resulting in varying claims. It is not uncommon to have two illuminators with a similar light output, that are quoted with wildly different maximum distances – because each manufacturer has a different opinion on what is classed as an acceptable image quality at their maximum distances. The first problem is... Read More
