Drones and CCTV are used by Attackers and Defenders respectively, in the Preparation phase (45 seconds). Each Attacker has two drones to find objectives and identify Defenders, and find a safe place to leave the drone for further use. Each Defender can access the CCTV cameras to gather intel, similar to the Attacker drones apart from that they're fixed in place.
Both the drones and the cameras give a monochrome feed in real-time, although active drones have a desaturated view. They can also Scan enemies to mark their position and identify them. A spotted enemy player will be alerted with "You've been spotted". Scanning an unidentified Operator will identify them.
Note: Some characters have special abilities that place more cameras for the team to use (Valkyrie's Mk2 "Black Eye" Gyro Cams), send out projectile cameras for their own visual feed/interface (Zero's Argus Launcher, Maestro's Compact Laser Emplacements "Evil eyes"), control extra drones (Twitch's shock drones, Echo's Yokai drones), or hack enemy drones (Mozzie's Pest Launcher), but these essentially function in the same way as the group cameras. There are also abilities that are not shown visually, but worth mentioning (like Lion's EE-ONE-D aerial drone that scans enemy movement, but isn't operated).
