(Note: I'm not very knowledgeable about this period in Russia. I'm piecing this together from a few sources.)
Somov's regiment was not sent due to the Napoleonic threat, but was part of the existing task of defending the enormous and sparsely populated Russian frontier.
In the larger context of the Russian Empire in 1800 this makes more sense. Russia is very large and had threats on all sides: "Tartar, Turk, Pole, Prussian and Swede" and now the French. Transporting an army in 1800 was very slow, mobilization could take months. Russia was too large to have a centrally located "reaction force" to respond to crisis. They had to have units in prepared positions near every potential hot spot to slow an invasion, or react to a raid, or put down a rebellion.
While they faced large, traditional, concentrated Western armies on in the West, in the east and south they faced disbursed raiding parties of Turks and Tartars. The southern and eastern fronts of Russia in 1800 were more like the frontier armies of the United States than the armies of Napoleon. They filled many governmental roles in sparsely populated areas: military garrison, police, civil engineers, and labor force.
To deal with this, Peter the Great instituted large standing armies and deployed them to potential trouble spots. Supplying and concentrating them across such large distances, and such sparsely populated land particularly in the east, was difficult. Catherine the Great dealt with this by creating a Military Commission who created administrative divisions close to the areas being defended. A large mass of troops was garrisoned in Moscow, centrally located on the Russian transport system, to quickly (for the time) reinforce hot spots. Tsar Paul further organized divisions into "Inspectorates" to deal with corruption. The divisions would now be overseen by inspectors reporting directly to the Tsar.
"Somov's Regiment" raised and sent one or two battalions to Kamchatka for what became the Kamchatskii Garnizonnyi batalion (Kamchatka Garrison Battalion). This was part of the larger Siberia Inspectorate of about 10 battalions in 1796. It was assigned certain hamlets, "cantons", which they defended, aided, and relied upon. Soldiers would help with the labor and farming in exchange for supplies and shelter. In addition, the regimental commander acted as a military government, parallel to the civilian one, within their territory.

There is a potential that this is true.
First (as mentioned in the comments) Russian intelligence was suspect at times leading to events such as What made the Russian Fleet suspect Japanese Torpedo boats were in North Sea in 1904/5?
What the Russians may have been reacting to here is Napoleon in Egypt and his 1798 - 1801 campaign there. Napoleon entered Egypt and advanced into Syria, most likely with the goal of marching a French/Ottoman army into India to aid the Maratha empire with their struggles vs the British. If Napoleon could challenge and ultimately usurp British rule in India, then Napoleon could have asserted French control over India. French control of India would be a stepping point to Kamchatka (though I doubt the intent was ever there).
Unfortunately for Napoleon, the English captured his ships carrying his artillery and the military campaign was halted in Acre forcing Napoleon to turn back, so the event they (may have been) reacting to never came to be.
