SESSION n°1: from 01/10/2012 12:00 a.m. to 09/10/2012 12:00 a.m.
First recording session in Monts d'Azur biological reserve, private reserve directed by M Patrice Longour
Stard date: lundi 01/10/2012
Start time: 12:00 a.m.
the deer belling began September 15, 2012 this year
10am arrival on site
11:30 a.m. arrival and choice of place of installation: installation
1:00 p.m. departure from the place of installation
sharing meal with Mr Longour and the tv team in its structure.
3:30 p.m. am: departure from the reserve for return to toulon
garmin etrex GPS coordinates
Degrees-Minutes decimales: DM.d
Accuracy ± 8 meters (for 3 decimal)
Practical notions about GPS a> N 43°48.746' E 006°51.238'
Now I set my gps not in Degrees-Minutes decimales but in Degrees-decimales D.d.
Accuracy up to 8 centimeters (for 6 decimales).
hypothetical example that has nothing to do with the coordinates above
SABIOD Box has been installed in an oak, at 2m50 from the ground
Leave SABIOD box on the floor is not an option because
-rutting deer are dangerous, very curious, and rub their antlers against everything that is not at 2m above the ground.
-bisons also are very curious, get rid of their summer wool rubbing against trees, bushes and rocks supports
-same with boars which we do not know the reaction but whose flair is formidable.
So we hoisted the SABIOD BOX 2.50m above the ground in an oak. Boxes and microphone are strapped.
The gain was adjusted using two earphones whose jack was plugged into the out jack port of the Beagle board. Patrice made noises to 10, 20, 30 meters to help me to adjust the gain.
The risk of falls are killed by simply using a strap that goes under the climber's arm and around his torso.
For a future record in another biotope in the same park, it would be easier to come with a wooden platform (by instance: a simple structure with four planks of 2 meters all that belt to a tree).
The first session during 8 days, it will be recovered Tuesday, 09/10/2012 and reactivated immediately for 15 days in another part of the park

SESSION n°2: from 09/10/2012 12:20 a.m. to 25/10/2012 16:30 p.m.
Departure from Six-Fours les plages: 5:45 a.m.
How to get there:
Motorway towards Nice. Take a little before Cannes exit 42 Mougins toward Grasse
Go to Grasse
Follow the Napoleon road
Follow Thorenc / Andon
Mr Olivier Dufour and Patrice Longour left reception desk of the reserve at nearly 10:10 a.m.
handling gloves (to break twigs and handling brambles without fears)
shears (to cut short the thin cords and brambles)
Ladder (lent by Mr Longour) enormously facilitate the installation of the equipment.
One strap to secure the climber
1 strap to fasten the main box
2 solid wood boards to create the foundation on which both batteries rest on
We recovered the SABIOD box located on the first location:
1-Disconnect the secondary battery connected in parallel to the main battery by pressure on the switch provided for this purpose. Remove on the ground the box containing the secondary battery.
2-Detach microphone from its branch and attach it to the main box
3-Down main box + microphone attached to it.
4-Open the main box and control the system: green leds of the motherboard and red leds of preamp were on as normal. The device was always on. No water found.
5-Connect headphones to the jack out port of the beagleboard (motherboard) to verify: the system was still correctly recording.
6-We stopped recording at 11:30 a.m. by pressing the switch.
total volume occupied by recordings on the 120 GB pendrive: 60 GB
We copied the recordings on the hard drive of a Windows MiniPC : copy time = 50 minutes.
We have taken advantage of this time to load up all the equipments in the four-by-four and to find a place for the second session.
Replace both batteries of session 1 (F 00534 and F00527) with two charged batteries (for this session 2):
F-00512: warning the battery is damaged on its top. His seal is maybe no more. Maybe it's easily reparable. Prefering avoid to lay down it, I put it in the main box (so vertically).
Gain of the session 2 is not the same than gain of session 1. I adjusted it ad hoc plugging the headphones hand playing with the potentiometer.
12:02:56 pm 43.81099 ° N, 006.84915 ° E
copy and paste directly into a google map or google earth or also geoportal (which has the advantages of also offer ign map for example)
Altitude: garmin etrex GPS informed 498m which is absurd. Patrice estimate altitude to 1300m.
Records of the Session 2 start at 12:20 a.m.
Recovery of SABIOD box:
At the opening of the main box, preamp LED was red (as normal).
But all green LEDs of motherboard beagle board, including three LEDS next to usb ports, were extinguished.
On the beagle board, only a red LED was lit next to the arrival of power supply port.
No sound by plugging a pair of headphones to the 3.5mm jack output port of the beagle (even by varying the gain of the preamp).
End of the acquisition
4:37 p.m. by setting off the main switch.
Within less than 10 meters, M. Longour noted the presence of fresh droppings of wild boar and deer and grasses grazed by bison.
