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. Letting trees return to bare and barren uplands, allowing the seabed to recover from trawling, and bringing back missing species would help hundreds of species that might otherwise struggle to survive – while rekindling wonder and enchantment that often seems missing in modern-day Britain.”

Alan Watson Featherstone, Trees for Life’s Executive Director, said: “Rewilding offers an exciting vision of hope, through the positive and practical work of renewing and revitalising ecosystems. In the Highlands we

How Trigger Interval Settings affect image transmission in Ltl Acorn 2G Cellular Cameras

This post is an explanation of how the interval time setting in the cameras menu affects the transmission of image data over a 2G cellular network.

This does not apply to the 6310 cameras with 3G modems when working over a 3G network, which were introduced at the end of 2016.

Acorn cellular cameras use the SIM900 GPRS 2G modem which can connect with either the GSM or the GPRS service. It is a class B device which means it can only use one or the other at a given time. 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
