Restricted Area

A restricted area is an area where Civilians, Guards and Cameras can detect you even in casing mode. It is best to go through a different route such as the White Building to the right of RO-Bank in which you can easily access the parking lot without being spotted by civilians or guards. If you are in a restricted area, a beige colored text notification on top of your screen will appear, saying: "You are in an restricted area". It is recommended to mask up in these areas as being unable to sprint, jump, crouch, and interact with objects is detrimental, unless you need to be in casing mode later on in the mission. Restricted areas are only a problem in stealth, as while you are inside a restricted area, NPCs and cameras can fill your suspicion meter as if you were masked up. Players should express caution in these areas and hide from cameras and NPCs, unless of course they decide they want to complete the mission with guns blazing and firing at you and your crew.

Strategies
Ways to avoid being detected in/get past restricted areas.

RO-Bank
To get past the restricted area on the roof (unless you are speedrunning or want to make a quick heist), go to the white building on the right of RO-Bank (from your spawn), then collect the cash in the building and near the tree (optional), then take out the guard and the cams like usual.

Downtown Bank
Look out for the cameras and guards! (It is better to do this with 2 people since the other player can hostage and kill the guard while you get the cameras) Before you get drilling, hostage all the civilians first! They will be alerted and trigger a loud heist if not taken hostage.

Nightclub
Enter the room by the left side. Once you are in, lock pick the door and kill the 2 guards upstairs and hostage the boss, insert the keycard and disable the cameras.

GMC (Golden Mask Casino)
Mask up and run as fast as you can to the objective, and make sure you don't bump into some of the guards that might be in the back.

Brick Bank
Did you deal with the cameras on brick bank? If yes, then do this: Hack the computer, if more than 2 employee gets alerted, kill or hostage all of them in a room. (If possible, try to just hostage them and hide them in the cubbies) Want to do the cameras fast? Don't worry! You need the skill Infiltrator that can instantly open doors by using melee, if you don't own the skill be sure to loop the camera near the door if there is. You can waste 1 of your EMC jammer to jam the slot or use the keycard to do it.

Jewelry Shop
Don't go in from the front! It is a restricted area with guards. Instead, go in from the left or right alleyway. Remember to deal with the cameras, pick lock the window and hostage/ eliminate the guards.

Authority
Remember: There is a schedule that guards will come to where you need to go, stop then go. They repeat the same so once you see no guards, mask up and do it.
