  We describe the compact objects in the $\infty$-category of $\mathcal
C$-valued sheaves $\text{Shv} (X,\mathcal C)$ on a hypercomplete locally
compact Hausdorff space $X$, for $\mathcal C$ a compactly generated stable
$\infty$-category. When $X$ is a non-compact connected manifold and $\mathcal
C$ is the unbounded derived category of a ring, our result recovers a result of
Neeman. Furthermore, for $X$ as above and $\mathcal C$ a nontrivial compactly
generated stable $\infty$-category, we show that $\text{Shv} (X,\mathcal C)$ is
compactly generated if and only if $X$ is totally disconnected.
