RESEARCHERS have developed a new technology that could triple the resolution density of displays and slash power consumption. For CCTV applications, the technology would deliver monitors capable of meaningfully supporting 4K CCTV cameras at wide angles of view.
The new technology could allow field-sequential colour displays where a single subpixel can be quickly switched among red, green or blue. By eliminating the colour filters traditionally used to spatially divide one pixel into red, green or blue subpixels, field-sequential colour displays allow the three subpixels to become three independent pixels and thus triples the resolution density.
SONY has announced the release of 8 new Full-HD video security cameras into its latest line-up, the sixth generation (G6) network cameras.
Using advanced imaging technology, Sony’s G6 cameras offer security professionals clear detail and higher
visibility with excellent low-light sensitivity, ideal for a wide range of demanding applications, including city, transport and commercial surveillance.
The new G6 cameras include V-series (SNC-VB640, SNC-VB642D, SNC-VM641 and SNC-VM642R), which are reported to offer double the visibility at minimum scene thanks to the Exmor R CMOS image sensor and XDNR noise reduction algorithms, and can maintain colour integrity at 0.1 lux in colour and 0.05 lux in monochrome.
Entry camera test array at Westfield, Bondi Junction
Last month Scentre Group’s National CCTV Camera Shootout was held at Westfield in Bondi Junction. This is the largest CCTV camera shootout of its type in Australia, with the diverse mall environment giving attendees plenty to think about across 4 camera groups.
WE often rattle on about objective camera testing in SEN and we do this because there is absolutely nothing that highlights strengths and weaknesses of performance more clearly than lining up a group of cameras in generally identical circumstances and seeing which image looks best. The challenge is getting all the latest cameras in one place – even more difficult, providing a series of real world applications that allow adequate conditions for comparison.
VMS functionality at the core of CCTV system capability
Nothing is so central to a surveillance solution as the video management system that drives it. Whether you’re an end user, or an installer, there’s plenty to think about when it comes to VMS and more and more products tout their ability to meet ever more complicated operational requirements.
WHEN you start thinking about VMS is hard to know where to start. Keeping things simple is beneficial – end users should think operationally and integrators should think operationally, while taking into account those aspects of the system that will best allow them to support an end user’s operational requirements.
Q: What is the infrared cut filter, what role does it play in a CCTV camera and do I need a day/night camera? I’ve heard of cameras that don’t need a cut filter but handle this task in software. Which is better?
A: Unlike the human eye, camera sensors can see infrared during the day – this impacts on the appearance of colour – green plants turn pink, for instance. In order to match the appearance of human vision, the cut filter only allows the visible light spectrum to pass, reflecting infrared using coatings that reflect or absorb IR wavelengths.
I WASN’T sure what to think of the Bosch IP 5000 when I unpacked it – the sunshade and the overall camera are quite light but when it’s up and running you find that this a surprisingly good camera in the best tradition of motorised, remote autofocus bullet cameras.
BOSCH’S IP 5000 day/night bullet camera is an IP66-rated 5MP bullet camera with a motorised, varifocal, IR-corrected, board-mounted 2.7-12mm F1.4 lens offering 32-100 degrees of viewing angle and 18-53 degrees of vertical angle. The motorized zoom lens has automatic focus adjustment with 1:1-pixel mapping to ensure the camera is always accurately focused. It works extremely well in the field.
Dave Sutherland at the Australian College of Physical Education
Force Security has installed a Bosch video surveillance solution to protect the Australian College of Physical Education (ACPE). The system incorporates a range of Bosch’s surveillance cameras supported by Bosch BVMS video management system.
THE Australian College of Physical Education ACPE) is Australia’s leading provider of specialist undergraduate and postgraduate degrees in the related disciplines of sport, dance, and physical education. One of Australia’s oldest higher education institutions, ACPE was founded in 1917 as a physical education training institute for young women, and was purchased by global education provider, Study Group, in 2009.
D-Link DCS-4802E IP66-rated outdoor mini dome camera
D-Link Vigilance DCS-4802E is a compact IP66-rated 1080p dome camera with a highly adjustable axis supported by an integrated 20m IR array. It features a wide angle of view, low distortion and reasonable performance for street, external residential and small commercial applications.
D-Link’s DCS-4802E is an IP66-rated outdoor mini dome camera that’s part of the company’s Vigilance PoE series of surveillance cameras. It’s compact – the camera is just 113mm in diameter, 85mm high and weighs in at 370 grams. Input is 12V DC and 1.5A, with a power consumption of 5.2 watts. Features include integrated IR array offering a viewing range of up to 20m, motion detection, built-in 802.3af compliant PoE module and ONVIF compliance.
Platinum AV has installed a Mobotix IP surveillance system at Lily’s in Sydney’s Seven Hills. The system includes automation, intercoms, external and internal cameras with edge storage, a dedicated network and remote and local management using mobile devices running the Australian-developed QCamPro app.
LILY’S restaurant, bar and function centre at Seven Hills in Sydney’s west incorporates 5 modern function rooms, 2 dedicated ceremony areas and an Italian restaurant. Arriving early, I spend 10 minutes wandering through the internal spaces, which revolve around a bar, pizza kitchen and large restaurant. It’s bigger than I expected. When you’re looking at video surveillance applications, the first place you look is the ceilings and I can see this is a brownfield site. New Mobotix cameras are dotted here and there across a ceiling populated by an installation of older, bulkier compact domes.
