+        Please analyze the image(s), which are in chronological order, strictly from the perspective of the {review_data["camera"].replace("_", " ")} security camera.
+        Your task is to provide a **neutral, factual, and objective description** of the scene, while also including **reasonable, evidence-based inferences** about the likely context or activity — but do not make unfounded assumptions.
+
+        When forming your description:
+        - Base all statements on visible details in the images.
+        - You may deduce plausible intent or context only if supported by clear, observable evidence (e.g., someone carrying tools toward a car may indicate vehicle maintenance).
+        - Avoid implying hostility, criminal intent, or other strong judgments unless the visual evidence is unambiguous.
+        - Distinguish between what is certain (facts) and what appears likely (reasonable inference).
 
         Here is some information we already know:
-        - the following activity occurred at {review_data['timestamp'].strftime('%I:%M %p')}
-        - the following objects were detected: {review_data['objects']}
-        - the following recognized objects were detected: {review_data['recognized_objects']}
-        - the activity happened in the following zones: {review_data['zones']}
+        - The activity occurred at {review_data["timestamp"].strftime("%I:%M %p")}
+        - The following objects were detected: {review_data["objects"]}
+        - The following recognized objects were detected: {review_data["recognized_objects"]}
+        - The activity happened in the following zones: {review_data["zones"]}
 
         Your response **MUST** be a flat JSON object with the following fields:
-        - `scene` (string): A single, comprehensive description of the entire visual scene.
-        - `action` (string): A single description of any key actions or movements.
-        - `potential_threat_level` (integer, optional): An integer from 0 to 3. Only include if a clear security concern is visible. Omit if no threat.
+        - `scene` (string): A comprehensive description of the setting and entities, including relevant context and plausible inferences if supported by visual evidence.
+        - `action` (string): A concise description of the main action(s) or movement(s) taking place.
+        - `potential_threat_level` (integer, optional): 0–3 scale. Only include if a clear security concern is visible:
+        - 0 = No concern
+        - 1 = Unusual but not overtly threatening
+        - 2 = Suspicious or potentially harmful
+        - 3 = Clear and immediate threat
+        Omit this field entirely if there is no observable security concern.
 
-        **IMPORTANT:** The value for each field (e.g., "scene", "action") must be a plain string or integer, NOT another JSON object or a description of the field itself.
-
-        Provide the response in the exact JSON format specified by this schema:
-        {ReviewMetadata.model_json_schema()['properties']}
+        **IMPORTANT:**
+        - Values for each field must be plain strings or integers — no nested objects or explanatory text.
+        - The JSON must strictly match this structure:
+        {ReviewMetadata.model_json_schema()["properties"]}
