+### Restricting alerts and detections to specific zones
 
 Often you will only want alerts to be created when an object enters areas of interest. This is done using zones along with setting required_zones. Let's say you only want to have an alert created when an object enters your entire_yard zone, the config would be:
 
 ```yaml
 cameras:
   name_of_your_camera:
-    record:
+    review:
-      events:
+      alerts:
         required_zones:
           - entire_yard
+    zones:
+      entire_yard:
+        coordinates: ...
+```
+
+You may also want to filter detections to only be created when an object enters a secondary area of interest. This is done using zones along with setting required_zones. Let's say you want alerts when an object enters the inner area of the yard but detections when an object enters the edge of the yard, the config would be
+
+```yaml
+cameras:
+  name_of_your_camera:
+    review:
+      alerts:
+        required_zones:
+          - inner_yard
+      detections:
+        required_zones:
+          - edge_yard
+    zones:
