Axis 233D Network Dome Camera – Now with Auto-Tracking

August 5th, 2008

The Axis 233D fully-functional dome camera now has auto-tracking capability!

Ideal for unmanned sites, the camera will now be able to detect and track movement within the scene.

This was already a great camera with its 35X optical zoom and progressive scan image clarity.

Existing owners of 233Ds can upgrade their firmware to gain this new functionality.

ACTi Network Cameras and Software Added

August 4th, 2008

We’ve just added ACTi’s megapixel dome camera (ACM-7411) and bullet camera (ACM-1231) into our webshop.

They’re offering FREE recording software (NVR Enterprise) for use with up to 16 cameras – if you’re looking for a new IP camera system for a home or small business requirement this could be a real deal-maker!!!

Please click the hyperlinks above to visit the product pages on our website. There’s a datasheet for each product which you can download from the datasheet link on each product page.

If you have any queries on the ACTi products, or perhaps Application Queries about how to use these or any other IP Video products, then please drop by our IP CCTV Forum and add your questions there, don’t be shy, it’s free to ask and we won’t bite ……

Amazing Detail in Panoramic Photos from Standard Digital Cameras

July 20th, 2008

I follow John Naughton’s Memex 1.1 Blog, John has a real nack of finding and promoting new technology, he’s just written a blog article on the GigaPan motorised robot pan device.

Which leads to this article in the New York Times Technology section.

It’s been developed by researchers at Carnegie Mellon University, in the States. You simply attach your standard digital camera and set it to pan across and take sectional images of a panoramic scene which can then be combined into a single Giga pixel image!

Take a look at some of those gigapixel results at gigapan.org. The results (from basic digital cameras) are amazing, and great controls on that website allow you to drag the image around and zoom-in to reveal fascinating details that you would not have believed were within the image.

One of the demo shots that I just checked-out shows a panoramic side view of Bath Abbey, it then zooms-in to the shop window at the very right edge of the panorama and shows the detail of a pattern on a mug in the shop window – real WOW technology!!

They hope to be able to make the Giga Pan device available for less than $500.

Can anybody see any surveillance applications for this????

Take a look at this example shot in a baseball stadium!

50 Megapixel Camera Sensor CCD Released by Kodak

July 17th, 2008

Just spotted this over at Technology Review:

Kodak have launched a 50 mega pixel CCD sensor.

Fifty million pixels in a 8,176 X 6,132 array!!!

Smaller pixels than ever before, with the promise of better colour rendition from improved pigments, just as sensitive as previous larger pixels, using less power than before AND processed faster than previous CCD camera sensors!

Other modifications and improvements to this sensor have improved the signal-to-noise ratio and increased the read rate – enabling the potential to read one frame per second at 50 megapixels!

Just one snag – the sensor alone will cost $3,500.

Helicopter Gunship Attacks Corner Shop!!!

July 17th, 2008

Right, now I’ve got your attention:

I see a lot of CCTV systems, can anybody tell me why so many cameras show so much of the sky??

Are they really expecting the above headline?

Did the system owner really ask the installer to monitor the sky?

The challenge for CCTV cameras is to capture useful evidence; as the size of the scene increases, the size of people within that scene decreases, and the usefulness of their images decreases too (bear in mind that Home Office guidelines for CCTV images to be admissible for ‘recognition of a known individual’ require us to capture their image at 50% of screen height).

So why waste valuable field of view on the sky?

To make matters even worse, the sky is often bright – to cope with the brightness of the sky the camera & lens combination will close the lens iris – this then results in what is on the ground being put completely into dim shade, and becoming a virtually useless image.

Tilt the camera down a bit.

Use a vari-focal lens and zoom-in a little; take the sky out of the scene, and fill the field of view with a useful scene.

For goodness sake – think about the image; less is more; just cover an agreed scene and deliver useful images!
