Graphic Processing Units Vital to 4K Camera Performance

You need to think about graphic processing units with 4K
You need to think about graphic processing units with 4K

WHEN it comes to GPUs – standard cards work fine with 1080p but with 4K you’ll have some issues with latency unless you plan ahead and ensure your hardware has an appropriate specification. 

With 4K GPU RAM is a factor – you want a minimum of 4GB and 8GB if you can get it – a 4K gamers GPU like the water-cooled Nvidia GTX Titan X with 12GB RAM would be great for multiple 4K streams, but you don’t need such a purpose-built tool. 

The Nvidia GTX 1080 with 8GB of RAM (yes, it’s actually 4K), is half the price and very good, too. Doing 4K properly is not plug-and-play, even if you’re only running a single camera. You’ll need to consider your underlying specification and infrastructure. 

A new laptop of good quality with a capable graphics card can handle 4K but not multiple streams in real time, while an older laptop can handle 4K at 12ips. ♦

Surveillance Drones Defended Boston Marathon

TETHERED CyPhy Works drones were deployed at the Boston Marathon to assist the security team in protecting runners and spectators.

The drones remained aloft for the entire race and were used to scan crowds and detect threats. They flew to 130m and their Sony cameras captured live video feeds which were transmitted in real time to operators at the MEMA control centre. Operators were able to zoom in, zoom out and replay video, as well as adjusting the position of drones.

The Persistent Aerial Reconnaissance Communications (PARC) drones are built by Danvers, Mass.-based CyPhy Works and were provided at no cost to the Boston Marathon, according to the Massachusetts Emergency Management Agency (MEMA).

Video Analytics Empowering CCTV Solutions

Video analytics empowering CCTV solutions
Video analytics empowering CCTV solutions

VIDEO surveillance coverage is vast and growing – not just in terms of scale but in terms of quality. Despite the improvement, many CCTV systems are static beasts – they record at fixed frame rates with fixed fields of view and the footage they generate is stored for investigation. 

But there’s a growing trend in which sees end users and integrators squeezing more out of CCTV systems using IVA – some of these lateral applications are not security or safety related but increasingly, many are.  It’s not surprising at one level. The underlying technology that generates stock reports for marketing teams is just as capable of delivering reports to security managers informing them in real time of large crowds or heavy vehicles driving where they should not be.

Panasonic Aero 30x PTZ Camera: First Impressions

Panasonic Aero 30x PTZ
Panasonic Aero 30x PTZ

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.

SPRT60XPM Digital Analogue CCTV Camera Review

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.
