PANASONIC Aero is a 1080p day/night, 30x optical, 1080x digital PTZ with 360-degree panning, 90-degree tilting with 150m of IR, 1P67 rating, IK10 rating, Video Stability Augment System and an operating temperature range between -50 and 55C.
I was very interested in the performance of Panasonic’s lovely Aero PTZ when the boys from BGWT bought it around to the SEN office and after spending a couple of days and an evening driving the camera, I formed a reasonable idea of where its core strengths lie.
SPRINT Intercom’s SPRT60XPM day/night bullet camera offers 4 format digital analogue streams giving TVI, AHD, CVI and CVBS via a 1/2.9-inch 2MP Sony CMOS sensor. There’s a 2.8-12mm motorised, autofocus zoom lens, de-fog, up-the-camera setting of on-screen display and 60m of IR. But how does it stack up against 1080p IP cameras?
SPRINT’S SPRT60XPM is a solidly made IP66-rated bullet camera with a metal body and an adjustable plastic sunshade. It’s an OEM product manufactured by Shenzhen SECTEC, an established manufacturer founded in 2001 in Shenzen China. Perhaps the most interesting feature of this camera is its ability to deliver 4-format digital analogue streams - TVI, AHD, CVI and CVBS. It’s a quality that allows the camera to be used with pretty much any digital analogue DVR, including the Dahua DHI-XVR5116HS penta-brid DVR I’m testing it with today.
How important is attention to focus with CCTV lenses, given many are wide angle lenses with very small hyperfocal distances? Shouldn’t everything in the field of view of such a lens be in focus?
WITH a wide lens, everything past the hyperfocal distance of a wide lens will be more or less in focus but that doesn’t mean focus will be as good as it could be for your operational requirements. There are plenty of compact cameras with fixed focal lengths and non-adjustable lenses out there - fixed lenses of around 4mm are becoming a trend. Most do an ok job but you only have to look at performance in the real world to see that they still have a focal sweet spot around 8-10m that gives maximum sharpness in the centre.
Released in May 2014, Fujinon’s varifocal F1.6 4.1-9mm (2.2x) megapixel lens is designed to support sensors up to 1/1.8 and resolutions of 6MP. The CS-mount lens supports near infrared wavelengths and offers horizontal angles of view between 100 and 45 degrees. In this feature we’re going to test the lens a couple of different cameras to see how it does.
MORETON Bay Regional Council has installed a comprehensive video surveillance solution monitoring high risk locations in the council area but the revelation audio is also being recorded from 330 cameras has attracted the attention of Queensland’s privacy commissioner, Phil Green.
After the cameras began recording audio on Monday, February 6, Green told the ABC he was in the process of enquiring to see if the use of the technology breached privacy laws.
"I'm still in the fact-finding mode — I obviously don't act rashly, I'm trying to look into this and have a rational, good public debate on the issue," Green said.
"If the public isn't happy with this sort of development, then the State Government can enact laws, but I think the laws already possibly stop this sort of thing happening."
Meanwhile, Queensland Law Society president Bill Potts told the ABC the public should be concerned.
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.
