How to Detect Anomalies in Night At The Infirmary

In Night At The Infirmary (Anomaly) by A.D. Games, patient imposters are designed to fool one inspection method at a time. Some look almost normal at the reception window but break on the printed photo. Others pass the photo yet expose void bodies or wrong proportions only on CCTV. Real human patients should match across all three layers — live window view, desk photo print, and security camera feeds.

Detection is not about memorizing every entry on all types before your first shift. It is about running the same repeatable loop on every arrival and treating the layers as an OR check: one confirmed red flag anywhere means reject with the shutter button. Only admit when window, photo, and CCTV all agree. This guide breaks down each layer, links to tell catalogs, and shows how to scan fast without skipping steps under queue pressure.

The window is your first and closest look at each human patient. Stand at the reception desk and scan before you touch the photo camera. Focus on features anomalies struggle to mimic consistently: eye movement and pupil size, mouth shape when speaking, teeth alignment, skin tone versus lighting, head tracking as you move side to side, and posture at the glass.

Common window red flags include unnaturally wide smiles, teeth that do not match normal human rows, eyes that track you too smoothly or not at all, and faces that flicker when the patient shifts weight. The full starter list lives on visual tells. Window inspection alone is never enough — some imposters look clean here but fail photo or CCTV. Use the window to flag suspects and to confirm when photo and CCTV already look wrong.

After the window scan, trigger the desk camera and wait for the print to develop. Hold the photo beside the live patient and compare feature by feature. Anomalies often break on the print because the snapshot captures details the disguise hides in motion — wrong eye count, static grain over the face, teeth that blur or multiply, or a smile that does not match the person at the glass.

Never skip the photo step because the queue is long. That shortcut is the most common reason players admit Skinwalkers in the current UPD 1 beta. Cross-reference suspicious prints with photo tells. If the live patient looks fine but the print shows any catalogued symptom, reject immediately — you do not need CCTV confirmation when the photo layer already failed.

Switch to the security monitors and find the patient on lobby and check-in angles. CCTV reveals tells the window cannot show: bodies that are hollow or incomplete, limbs at wrong lengths, figures that stare directly into the lens without blinking, or patients who appear in two places at once across feeds. Some anomalies look human at the window yet show void torsos or stretched silhouettes only on camera.

CCTV also drains Sanity when you stare at certain imposters too long. Scan efficiently — confirm or clear the patient, then look away. Full symptom lists are on camera tells. In squad play, assign one player to hold CCTV duty so the window operator is not forced to alt-tab between feeds under pressure. Solo players should still run this layer on every patient; use the anomaly checklist tool to stay structured.

Run layers in a fixed order every time: window, photo, CCTV. You may abort early — if the window shows an obvious tell, take the photo anyway for practice but you already have grounds to reject. If the window is clean and the photo fails, reject without needing CCTV. If window and photo pass, CCTV is your final gate before raising the shutter.

Call out findings in squad play so one voice makes the admit or reject decision. "Photo teeth wrong" or "CCTV void body" should be enough for the desk operator to press the shutter. For legitimate patients, all three layers match and you proceed to intake paperwork on the registration PC. See how to reject patients for shutter timing after a failed check and controls for exact desk bindings.

Speed comes from repetition, not from skipping layers. After ten shifts the window scan shrinks to a few seconds because you know which five features to check first. Photo comparison gets faster when you flip the print once instead of studying it for half a minute. CCTV review speeds up when you memorize which channels show the reception queue on the map.

Study tell categories between sessions — not during a live queue. Read anomalies hub pages on breaks, then apply one new category per night. Pair this guide with beginner guide if you are still in your first three nights, or how to survive shifts when Sanity drops make tells harder to read mid-queue.
