Visions of a rewilded Scotland – from restored forests to the return of predators such as the lynx and wolf – was in the spotlight on Monday 6th October at a topical lecture featuring acclaimed writer George Monbiot and award-winning conservationist Alan Watson Featherstone of Trees for Life, at the University of Edinburgh’s George Square Lecture Theatre.

With enthusiasm for rewilding – the large-scale restoration of damaged natural ecosystems – spreading quickly in the UK, the Rewilding the World event highlighted the significant benefits that this could bring to Scotland, together with a discussion on its global and ethical implications.
George Monbiot said: “Rewilding offers us a big chance to reverse destruction of the natural world.

How Trigger Interval Settings affect image transmission in Ltl Acorn Cellular Cameras

Fig 1: 6210 Wireless PCB and SIM900 Modem
This post is an explanation of how the interval time setting in the cameras menu affects the transmission of image data over a cellular network.

During GSM service ( voice call, SMS and MMS ) the GPRS service is suspended, and then resumed automatically after the GSM service has concluded. 


Acorn cellular cameras utilise the SIM900 wireless modem to provide GSM ( SMS and MMS ) and GPRS ( internet access for sending an image in an email using SMTP ) functionality. 

In Acorn cellular cameras the SIM900 prioritises the GSM service when programmed by the user to periodically listen for SMS remote control messages. The SIM900 also prioritises the GSM service in response to a trigger

This web site is about the wildlife, particularly the mammals, of the Glen Affric National Nature Reserve area in the north west Highlands of Scotland, UK; and the equipment I use to search for them, which is chiefly trail cameras.

I provide a technical support and parts service for the Ltl Acorn range of cameras and the income from this provides for the upkeep of this site and the purchase of cameras for my own surveying.

I hope you find the site useful and informative; and please contact me if you have any questions that I haven't already covered.
