ATM Robbery Detection Dataset: Gun and Knife (CCTV, YOLO): free 237-image sample

This ATM robbery detection dataset is a free sample of 237 synthetic CCTV images of armed robberies at cash machines, with YOLO bounding boxes for offender, victim, gun and knife, for training and testing robbery and weapon detection models on bank and ATM cameras. The labels say not only which weapon is present but who holds it and who is threatened. The full 3,000-image dataset balances handgun and knife robberies across exterior walls, vestibules, drive-up kiosks and street-corner ATMs, from bright daylight to low light. Made by Simuletic, a Swedish company that has built synthetic CCTV datasets for computer vision since 2023.

What's in the images

Armed robberies at cash machines, seen from a high-angle ATM security camera. In each scene an offender threatens a victim at the machine with a handgun or a knife, often while the victim is using the ATM. About half of the images show a handgun robbery (118) and half a knife robbery (119). They come from 48 scene setups with up to five images each, in daylight and at night. The images have the look of real security cameras: low resolution, sensor noise, JPEG compression artefacts and washed-out colour in low light.

The labels mark people by role, not only the weapon. A plain weapon detector can say that a knife is in the frame; these labels also say who holds it and who is being threatened, so a model can learn to tell a robbery from two people simply standing close together at an ATM.

Classes and boxes

Class	YOLO id	What it marks	Boxes in sample
offender	0	the person making the threat, closest to the weapon	237
victim	1	the person being threatened, usually at the ATM	235
gun	2	handguns and pistols, often held at chest height	122
knife	3	pocket knives, kitchen knives and other blades	118

Every image has one offender box. A gun is boxed in 121 images and a knife in 116.

Quick start (Ultralytics YOLO)

Create a data.yaml next to the CCTV_ATM_Robbery_Knife_Gun_Detection_Dataset/ folder:

path: CCTV_ATM_Robbery_Knife_Gun_Detection_Dataset
train: images
val: images   # small sample: use the same images, or split them yourself
names:
  0: offender
  1: victim
  2: gun
  3: knife

Then train:

from ultralytics import YOLO

model = YOLO("yolo11n.pt")
model.train(data="data.yaml", epochs=30, imgsz=640)

Use cases

• Real-time ATM robbery alerts, for example a silent alarm when a weapon is drawn at a cash machine
• Security analytics for bank lobbies, ATM vestibules and street-corner kiosks
• Role-aware threat detection: telling an offender from a victim at close range
• Gun and knife detection on small, partly hidden weapons in CCTV footage
• Pre-training before fine-tuning on your own ATM camera footage

Full dataset and prices

The full CCTV ATM Robbery Detection Dataset: Gun & Knife has 3,000 images, YOLO, classes offender, victim, gun, knife. Every licence is a one-time payment, perpetual, for one organisation; you get a download link within five working days (card or invoice). Research covers students and non-commercial work and is available for 1,000 images only; packs of 5,000 images and more are sold with the commercial licence, which lets you train models and ship them in products.

	Research	Commercial
1,000 images	$149	$590
5,000-image pack	not offered	$2,400
10,000-image pack	not offered	$4,500
20,000-image pack	not offered	$8,500

Packs are the same dataset at larger size, with the same labels and split, under the commercial licence. 50,000+ images, video datasets and enterprise agreements (from $10,000) are quoted. Other scenes, camera angles or classes: custom data or contact@simuletic.com.

How the images were made

The images are fully synthetic (computer-generated) by Simuletic: no real people, places or incidents are depicted, so there are no privacy or consent issues.

Limitations. Synthetic images do not cover every camera, lens, compression artefact or scene you will meet in deployment. Validate on your own footage, and for production combine synthetic and real data. This sample has 237 images from 48 scene setups; the full dataset has 3,000 images across more ATM locations and lighting conditions.
