All houses and skyboxes come with a security device. Seacliff has converted the home security systems to the CasperSafe system. Security Orb is a white sphere usually positioned nearby the rent box.
You will be automatically given control of the Security system when you pay rent and conversely, removed when you leave. Similarly if you have a co-tenant added to the rent box.
Touching the box or right click and "touch" will give you a control menu. The menu is very simple with an Arm/Disarm button and button to edit your whitelist (AKA Guest List). Add your friends to the "guest list" so thay can visit while the orb is Armed. Insert your friend's name into the box that appears on clicking the "guest list" button in "firstname lastname" format. Do not use the avatar's display name. If your friend has a single user name enter the name as "name resident."
