The monopole detector is coupled to a massless complex scalar field in such a way that it is sensitive to the Lorentz violation due to the noncommutativity of spacetime present in the $\\kappa-$deformation. The response function deviates from the thermal distribution of Unruh temperature at the order of $1/\\kappa$ and vanishes exponentially as the proper time of the detector exceeds a certain critical time, a logarithmic function of $\\kappa$.
