SPRT60XPM Digital Analogue CCTV Camera Review

SPRT60XPM day night bullet camera
SPRT60XPM day night bullet camera

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 Focus With CCTV Camera Lenses?

CCTV lens focus is more important that you think
CCTV lens focus is more important that you think

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.

Fujinon F1.6 4.1-9mm Varifocal CCTV Lens Review

Fujinon varifocal F1.6 4.1-9mm
Fujinon varifocal F1.6 4.1-9mm

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 Council CCTV Camera Audio Recordings Causing Big Noise

Moreton Bay Regional Council CCTV System cameras
Moreton Bay Regional Council CCTV System cameras

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.

Blue Phase Liquid Crystal Offers 1500-Pixel PSI Video Displays

High resolution screens would empower 4K cameras
High resolution screens would empower 4K cameras

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.

Scentre Group CCTV Camera Shootout: Full Report

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 Functionalities: Thoughts For Integrators & End Users

VMS functionality at the core of CCTV system capability
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.

IR Cut Filter or Night Mode in Software – Which is Best?

Basic IR Cut Filter Mechanism
Basic IR Cut Filter Mechanism

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.

Bosch IP 5000 Bullet Camera Review

Bosch IP 5000 Bullet camera
Bosch IP 5000 Bullet camera

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.
