We have just launched our new Luma Surveillance Calculator tool which can be found under the ‘Support’ section of our website. This brand new tool allows you to calculate Lens Field of View and Power Wire Length options for Luma Surveillance Cameras. You can can also use the tool to calculate DVR / NVR storage needs for all Luma Surveillance DVR and NVR products. Please visit the Support page to access the Luma Surveillance Calculator tool online.
