Sony have recently introduced the
SNC-VB770 – dubbed the industry’s highest sensitivity 4K network camera. That’s quite an accolade and the datasheet certainly details some impressive specifications – the most pertinent of which is a minimum illumination level of less than 0.004 lux.
If you’re thinking “that’s almost pitch-black light conditions”, you’d be right and that means capturing clear 4K images in colour – even in extremely low light conditions. To put these light levels into perspective, it’s the darkness that you’d encounter on a starry night with no other light source or indoors with such poor lighting that it’s even a challenge for the human eye to see the object.
The camera uses a highly-sensitive 35mm full-frame Exmor sensor and optimised E-mount lenses to maximise the performance of both the sensor and its signal processing engine.
Back in October last year, the Axis F-series cameras were launched, comprising a main unit and separate ultra-compact sensor modules; a concept never seen before from the leading IP video manufacturer. Not only did this enables discreet sensors to be placed up to 12m away from the main unit, but also provided a cost-effective and covert solution for small space monitoring such as ATMs and for mobile applications such as transport. With the recent release of the new F44 main unit and F1025 and F1035-E sensors, we take a look at the complete Axis F-series and what it offers…
The latest edition to the Sony outdoor camera range is the innovative SNC-VB632D infrared bullet network camera. Not only is the new model capable of HD 1080p at 60 frames per second it also incorporates Sony’s newly adopted Dual-Light system for ultimate night-time surveillance. Using both infrared and white light LEDs, the SNC-VB632D delivers high performance illumination during night-time, even providing a visual deterrent to intruders.
Not only do the new Axis Q35 cameras offer 60 fps video capture, wide dynamic range and edge recording amongst plenty of other features, the particularly interesting thing about these recently launched cameras is that they are the first Axis network cameras to offer both HD 1080p / 2 megapixel and Lightfinder technology. In the past we have only seen HD 720p /1 megapixel cameras with Axis Lightfinder. However advances in technology are enabling even higher quality low light image capture.
You may be aware of the ‘Shellshock’ bug or ‘Bashbug’ which was recently discovered in Linux operating systems. Many of the web servers on the Internet use Linux to host websites or web applications. By the same token, most IP cameras use the same technologies as part of their on-board operating systems and therefore may pose a hacking risk to your organisation.
With quick and easy access to IP video systems from mobile devices being ever more important, Axis has launched its own mobile app for Axis Camera Companion (ACC). Mobile surveillance apps allow access to an IP video system using the internet, and provide handy remote live viewing and management of recorded video whilst away from a site. Until now, only third party mobile apps were available to access Axis cameras, but this is no longer the case…
We mentioned in our recent Ifsec 2014 review that the first 4K IP cameras were on display at this year’s security exhibition. Following up on this we just wanted to share with you what 4K actually looks like. At 3840 x 2160 4K cameras offer four times the resolution of a full HD 1080p camera, and at full frame rate. This will mean even greater detail from even larger areas.
We’ve just spent three days at the annual security exhibition IFSEC, taking place at the Excel in London this week. It’s a huge show and impossible to look at everything but overall the sense is that the evolution of IP-based security technologies is continuing to gather pace and analogue-based solutions have now been marginalised. I did not see one analogue camera on the show at any of the main stands, but then I was not looking for one.
Axis has launched the T83 series of compact microphones providing high-performance audio in most scenarios. The new microphones are compatible with Axis network cameras with audio input support, offering high quality audio data that can add valuable information to CCTV monitoring operations.
The market for IP bullet cameras with integrated infrared LEDs has been a crowded place for years, mainly dominated by lower-end manufacturers. Premium brand manufacturers have been cautious with building infrared LEDs into their cameras for a long time but in recent years we have seen some mid-range and higher-end products appearing from the likes of Axis, Sony and Panasonic. The reason for this is that LED technology has improved a lot and LEDs have become much more durable, now matching the longevity of other components used in cameras. We anticipate a trend that premium manufacturers will increasingly expand in the lower-cost market for infrared IP cameras, since there is a high demand for this type of product worldwide.
