Black Hawk IR dome from 360 Vision

Answering the age old problem of how to illuminate PTZ dome pictures at night time, 360 Vision have announced the availability of their Black Hawk IR Dome range

Drawing on over 20 years of CCTV Manufacturing,  the 360 Vision Technology Black Hawk IR Dome with twin LED IR illuminators is available in a choice of either Cool Grey, White or Black.

Options include:-

  • Dual 830nM wide angle IR Lamps providing 100m of illumination
  • Sony Ex-View WDR Camera options in 18x, 26x and 36x zoom
  • Multi Protocol Integration
  • OSD
  • Motor Motion Design
  • High Quality Components
  • Intelligent Alarms
  • Creative Privacy Zones
  • True Day/Night performance
  • Picture Freeze and Fast Shutter

we certainly think this is a great addition to their range – domes have always suffered from a lack of travelling illumination as found on the older overt PTZ units.

we think that the Black Hawk is a great ‘in between’ product, sitting perfectly between their VisionDome and Predator range !

we hope to bring a review shortly of the claimed 100m IR range……

HD cameras – can they be the same?

An interesting demo came up recently…..

we took a few cameras, HD 1080p to be precise, from a very renowned IP Manufacturer,,,,,,,,,,,

a couple were mini dome based, the type you see in the analogue arena, you know, Vandal Resistant with varifocal lens, 3 axis, day night etc etc

the others were ‘boxed’ cameras……..the type where you fit the lens, usually (and recommended) a high quality lens designed for Megapixel use………

putting them side by side, adjusted to look at exactly the same picture………….both 1080p cameras from the same manufacturer………..

The Result

well, both were excellent pictures – it cannot be denied – but, they were not identical……….not by some margin………. the mini dome was ‘softer’, a little more ‘noise’ in the picture whereas the ‘boxed’ camera was sharper, more ‘vivid’ colours………….electronically zooming in revealed that actually, the mini dome, despite the ‘noise’ was actually a sharper picture, the ‘boxed’ camera had a degree of ‘pixelaion’ which detracted away from the initial sharpness………….

turning the lights off to test the day/night function highlighted the difference again………..the mini dome wiped the floor with the ‘boxed’ version camera!!! that puzzled us !

talking with the manufacturer, the mini dome is a smaller lens, smaller sensor, limited in optics to fit inside the dome………..that we can understand……….but how was it better under low light??

Lesson learnt

so, it is imperative that when specifying a system, particularly with IP MEgapixel, be aware that even with the same manufacturer, you will sometimes see a difference in picture rendition………..

what are your experiences?!

Navtech Radar

An interesting twist on Perimeter protection!

We became aware recently of a new, emerging technology in the Security Industry……….Radar

It’s not a new technology, but certainly new in our industry.

Is it expensive?

Well, yes…….but, you need to look beyond the capital outlay and see what it replaces…

historically, protecting a huge perimeter, such as that of an airport, would involve 10’s or even 100’s of sensors, whether beams or detectors, alarm or dedicated CCTV beams such as those from companies like Optex etc…..

but, one single Navtech Radar unit, placed centrally, can monitor movement in an 800m 360 degree zone………and link various zones to multiple cameras……controlling PTZ cameras such as MIC-400 from Bosch or the new and excellent 360 Vision Predator product, moving them automatically to moving objects and dynamically tracking as the object moves within the detection zone………

Offering a complete revolution of the mentioned 800m 360 degree view in ONE SECOND this represents a very different way to think of sensor detection.

We think this is a very exciting new product, there is defintely a cost increase, but we are prepared to bet that if installation costs and labour are factored in, there is very little in it!

FLIR PT-series thermal IP cameras

FLIR release new range.

The popularity of thermal imaging cameras has increased steadily in recent times as the CCTV security industry find more and more applications for them.With the advent of IP and analytics, together with a reduction in cost, means that suddenly solutions exist that were not there before.

The new FLIR PT-Series.

 The new FLIR PT-Series has been specifically aimed at this market place. Programmable scan patterns and slew to alarms  gives this range of cameras some interesting extra features. The ability to see in total darkness and in any weather, along with easy integration to either analogue or TCP/networks are all valuable selling points.

More Pixels.

By incorporating a high resolution 640 x 480 pixel detector the camera can give up to 4 times the image clarity of previous cameras. It also gives better performance over longer ranges. More pixels mean more detail and the ability to detect smaller objects that would previously have been missed. This all comes with the savings that can be made when expensive lighting systems can be shelved.

On site repairs and upgrades.

Flir have also introduced the interchangeable camera cassette that allows you to upgrade existing FLIR cameras. This can be done in the field and takes only a few minutes, keeping installers and end users happy and no break in camera coverage while the unit is returned to the factory.

Conclusion.

It would appear FLIR are now developing their cameras to fit more and more into security applications in the commercial market place. This has been achieved with more competitively priced cameras that come with more choice of lens size and more built in features.
