I finally build my proto and it works fine, but i'm disappointed : it's
slow...

curl "http://download.geofabrik.de/osm/europe/france.osm.pbf" \
        -o "./temp/france.osm.pbf"
osmosis --rb "./temp/france.osm.pbf" \
        --tf accept-nodes "man_made=surveillance" --tf reject-ways \
        --tf reject-relations --wx "./temp/frn.xml"
osmosis --rb "./temp/france.osm.pbf" \
        --tf accept-ways "man_made=surveillance" --tf reject-relations\
        --used-node --wx "./temp/frw.xml"
osmosis --rb "./temp/france.osm.pbf" \
        --tf accept-relations "man_made=surveillance"  --used-way\
        --used-node --wx "./temp/frr.xml"
osmosis --rx "./temp/frn.xml" --rx "./temp/frw.xml" \
        --rx "./temp/frr.xml" --merge --merge \
        --wx "./data/fr_surveillance.xml"

75 minutes to download 1.2 GB of data (France)
60 minutes to filter and merge "man_made=surveillance" for nodes, ways
and relations...

Previously it requires only 10 minutes via XAPI (when server were up).
But XAPI is no more a solution (see above)
