Pinhole cameras serve as the primary diagnostic for emittance and energy spread measurements in the storage ring of Diamond Light Source. Similar pinhole cameras will be employed for the Diamond-II upgrade, to enable direct imaging of the stored beam while also allowing for the monitoring of skew, profile, position, and instabilities. The emittance and coupling are calculated from the acquired beam size measurement, combined with the lattice parameters. In this paper, an overview of the new system for Diamond-II is presented. The changes and upgrades made to the existing setup, the challenges and the choice of the different components are described. Additionally, future work that could improve the performance of the system is explored.
