Events: Security Expo 2015

I had the good fortune to be invited to attend the 2015 Australian Security Exhibition & Conference a couple of weeks ago, which shows it pays to stay in touch with local industry events, so I took a long lunch one day and attended.

The Security Exhibition Conference is the most highly recognized security industry event in Australasia. This year was its 30th anniversary.   The event is billed as the must-attend event for all security professionals from installers and integrators to end users. It's not exactly my comfort zone, and it was great to see what other new industries show themselves to their peers.

The Security Exhibition showcased  170 leading brands in one place and allowed visitors to identify the newest and brightest industry innovations. My best explanation for what I saw, is that there were cameras. Lots of cameras. 3/5 of the expo was camera or camera related.

Thermal cameras, low light cameras, super hi-def cameras. Cameras in does, cameras on poles, cameras on drones. All the downstream systems to process all of that, facial recognition systems, networking, storage, scanning systems. A lot of camera stuff.

About 1/5 of the expo was access-control: ID badges, doors, code-pads, RFID scanners, readers and writers, and the like. Some locks and barrier systems too.

One thing I noted that was curiously absent, from my way of thinking was any counter-technology. There were no lock-picks, code-breakers, spoofers or any other sort of bypass tools, but I suppose that kind of thing might be at an even more secret expo.

Even then, getting into the Security Exhibition & Conference isn't that easy. I had media-type entry, but otherwise they accept professionals in the security industry and end users responsible for sourcing the latest products, services and technologies to manage security threats and protect vital business assets. Entry is otherwise restricted to industry professionals only. People not in this category are not be admitted at any time. Proof of identity and industry involvement may be requested at the door, I had my patches on, and cards at hand, but wasn't challenged, having been invited.

It was a very interesting event to visit, and I made a couple of contacts that I will be following up, such as with Defence Systems Australia, so stay tuned for a post about them. If you are interested and actively in industrial and corporate security I'd heartily recommend attending.

Probably not too useful to the backyard prepper and urban scavenger, unless you're into grey-hatting.

Rreview: PublicLabs - Infragram Plant Cam

I'm always excited to be able to work with extra-human wavelengths of light. I love my UV torches like the UV Jil Lite JenyxUV, and the SpiderFire x6v IR and the Phoenix Jr and the Manta strobe. Not to mention my Yukon NVMT 3x42 IR scope.I've wanted to get into thermal imaging, but it's way to expensive for a dilettante like me at this stage, so I jumped at the chance to get a near-IR option.

I backed a Kickstarter, the Publiclab Infragram the infrared photography project which developed a modified Mobius Action Cam with a 133 degree wide-angle lens, timelapse and still photography at a resolution of 2304 × 1536, and 1080p video. It is modified with a red filter and custom white balance.  The camera comes with an SD card and standard 1/4-20 tripod mount.I added some fishing line, just to keep the fiddly lens cap attached.

Near-IR photography takes advantage of the fact that digital cameras are sensitive to IR and by removing the infrared-blocking filter and adding a specific blue filter the modified Mobius Action Cam  filters out the red light, and measures infrared light in its place using that piece of carefully chosen "NGB" or "infrablue" filter.

The end result are these interesting blue-removed, IR-reflective and photosynthesis inferring photos. I've taken them from various angles in my front yard, with the Mobius and then with my iPhone5.

Infragram offer a selection of web-based filters which allow you to pick out and distinguish different aspects of the wavelengths captured, allowing you to not only pick out where plant life is thriving, or failing to thrive, but also pick out areas and items that might appear to fit, but are not.

This kind of photography will allow for assessment of crops, keeping track of invasive species, and possibly even be used to scan for roaming bands of government agents tracking you down ...
