Using image rotation to optimise coverage and bandwidth usage

March 8th, 2017 by Nathan Mount

Demonstrating how rotating the image is beneficial

When choosing a camera for video surveillance in narrow scenes such as long corridors, staircases, aisles and tunnels, the traditional landscape-oriented setup may not be the optimal choice. If you’re monitoring a narrow corridor or passageway, a sizeable portion of the scene is going to be walls either side, making a lot of your image redundant. The full area and resolution of the camera’s image sensor is not being fully utilised and this means that evidence of events occurring outside this limited area of coverage may be missed. These redundant sections either side of the image also consume bandwidth and storage that could really be put to better use.

This is where the ability to rotate the image proves to be very handy. This feature allows you to obtain a portrait-oriented video stream – effectively turning an HD camera’s 16:9 aspect ratio to a 9:16 aspect ratio. By filming in this orientation, you are ensuring that the whole sensor covers the area of interest, maximising coverage and eliminating bandwidth and storage waste.

The benefits of live streaming your next event

January 26th, 2017 by Nathan Mount

benefits of live streaming

Your next event is all set up and ready to go. The guest speakers have their time slots and your attendees have settled into their seats. There’s no reason why it shouldn’t be a great success and all the people invited will find it rewarding and informative. But, have you ever thought that maybe you could get even more out of your events?

Could you be reaching a wider audience? Is the marketing potential maximised? Are you getting best value from your venue? These are all things that live streaming your next event could help improve.

This medium has become increasingly more popular in recent years and is already being utilised by a wide range of organisations including companies promoting their services, universities streaming educational seminars and start-ups conducting Q&A sessions.

There’s no reason why you can’t do the same and in this blog we pick out some of the big benefits to live streaming your next event.

Axis’ high-performance Q6155-E PTZ introduces laser focus technology

January 11th, 2017 by Bethanne Pugh

Axis Q6155-E laser focus technologyu

Conventional PTZ cameras may take longer to autofocus in difficult lighting conditions and this can result in a loss of detail during the time taken to achieve optimum focus.

Using Axis’ innovative laser focus technology, in combination with a host of other advanced features, the new Axis Q6155-E offers clear imaging as well as faster and more precise focusing – even in the most demanding conditions.

Laser focus utilises the camera’s integrated laser to measure the distance between the camera and objects of interest – regardless of lighting conditions. This method is much more exact than the auto-focus techniques currently used in most other cameras and the measurement is taken instantly too. This means the unit is always optimally focused and delivers clear images at all times. Laser focus is not currently available in other PTZ domes on the market today. However, if the technology stands up to claims of offering improvements in PTZ performance and instant identification of people or objects – we can see it being rolled out in the next generation of high-end PTZ units by Axis.

Bosch begin adding edge-based video analytics as standard

August 25th, 2016 by Paul Sandford

Bosch video analyticsBosch is renowned in the world of IP CCTV for its background in engineering and the ability to create innovative products.

They’re a manufacturer that prefers to launch new technology only when they’ve been able to maximise its full potential, so when we heard they were introducing edge-based video analytics in their cameras, we wanted to know more.

There are two types of Bosch video analytics – Essential Video Analytics and Intelligent Video Analytics. You could think of these as “Standard” and “Advanced” but it’s fair to say that even the “Standard” version is feature-rich with a varied choice of intrusion, object, direction and behaviour related motion detection rules including people counting and crowd detection.

Axis improves Zipstream with dynamic frame rate

August 24th, 2016 by Paul Sandford

Zipstream with dynamic frame rate - everything you need with LESS of what you don'tZipstream has been around for a year now. In that time it’s already proven itself as a game-changing technology, able to lower bandwidth and storage requirements by an average of 50% or more without sacrificing important details.

Development has continued and earlier this year Axis enhanced Zipstream so it could adapt to PTZ camera movements. Now, just when you may have wondered if could get any better, Axis announced another enhancement – dynamic frame rate.

Creating a free to use CCTV system easily with an app and no PC

August 11th, 2016 by Paul Sandford

App-based CCTV ideal for small businesses and home usersIf you’re a small business or home user seeking a simple CCTV solution, you’d probably like to be able to mount your new IP camera in a suitable location, connect it to your network and then use a free app on your mobile phone or tablet to access live video and recordings whilst on the go. That’s it – safeguard your business or home with no complicated set-up and configuration. Some might call this approach “Plug and play”.

Until recently, it’s not been that easy and as a minimum, a PC was still required during the installation of the IP camera. Now it’s possible to do using just a mobile app and although we probably wouldn’t use the phrase “Plug and play”, the solution is certainly very straight forward.

Both Axis and Hikvision support this app-based approach and we’ll outline how to get up and running, weigh up each brand’s offering and consider the limitations.

Latest high-end fixed domes from Axis will use new remote PTRZ to reduce installation time

July 4th, 2016 by Paul Sandford

Axis Q36 series IP camera capable of pan, tilt and rollEver the innovators, Axis are always looking for ways to make the installation of their IP cameras more efficient. Having recently announced the introduction of an intelligent CS-mount lens for accurate optical adjustment during installation, Axis has now made physical adjustment of the lens even easier.

The new Q36 series will offer exceptional image quality and uniquely, remote pan/tilt/roll/zoom (PTRZ) will greatly reduce the time it takes to set the view during installation. The cameras’ PTRZ function also means that should surrounding conditions change and adjustments to the view are required, a site visit may not be necessary. Axis has also included a smart conduit connection and cable management but there’s more to these new cameras than quick and reliable installation.

Behavioural analytics now available in Mobotix hemispheric ceiling cameras

June 22nd, 2016 by Paul Sandford

Example of Mobotix behavioural analytics U-turn eventMobotix has now made behavioural analytics available to monitor specific human and vehicular patterns of movement. Once configured, the camera can count objects or people moving in a defined corridor and the user can be notified of several different events including “Duration of stay”, “U-turn”, “Opposite direction” and “Speed”.

All Mobotix cameras have built-in analytics and although these new behavioural analytics form part of the MX Analytics suite, these new tools are only available with the c25, Q25 and S15M. This is because they’re most effective when deployed using a panoramic, top-down field of view and that typically means being mounted in a ceiling.
