CCTV Weapon Detection Dataset (free sample)

A free sample of 141 synthetic CCTV images of people holding guns, with YOLO bounding boxes for person and weapon, for training and testing weapon detection and gun detection models on security-camera footage. Made by Simuletic, which builds synthetic CCTV datasets for computer vision.

Full dataset and licence: simuletic.com/datasets/cctv-weapon-detection-dataset

	Free sample (this page)	Full dataset
Images	141 PNG, about 1,100 × 1,100 to 924 × 1,358 px	1,000 JPEG (900 train / 100 val)
Classes	person, weapon	person, handgun, rifle, shotgun, sniper_rifle
Labels	YOLO .txt + one CSV of pixel boxes	YOLO + COCO
Camera view	elevated CCTV angles, indoor and outdoor	ceiling, wall and pole mounts; day, night and monochrome IR; about 20% hard negatives
Licence	CC BY 4.0	one-time licence: research $149 / commercial $590

What's in the images

People holding or carrying firearms in public and semi-public places (entrances, corridors, streets, car parks), seen from elevated security-camera positions. Weapons are often small in the frame, as they are in real CCTV footage. The sample comes from an earlier Simuletic release and uses two classes; the full dataset separates weapon types and adds hard negatives.

Classes and boxes

Class	YOLO id	Boxes in sample
person	0	139
weapon	1	130

Folder layout

samples/
  images/                  # 141 PNG images (Scene1_1.png, ...)
  labels/                  # one YOLO .txt per image
  annotation_sample.csv    # the same boxes in pixels

Each YOLO label line is class_id x_center y_center width height, normalised to 0–1:

0 0.452 0.551 0.203 0.302
1 0.601 0.703 0.102 0.151

The CSV has one row per box: label_name, bbox_x, bbox_y, bbox_width, bbox_height, image_name, image_width, image_height (pixels, top-left origin).

Quick start (Ultralytics YOLO)

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

path: samples
train: images
val: images   # small sample: use the same images, or split them yourself
names:
  0: person
  1: weapon

Then train:

from ultralytics import YOLO

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

A Colab notebook that fine-tunes YOLO11 on the newer 5-class sample is in the GitHub repo.

Use cases

• Gun and weapon detection on CCTV and video management systems (VMS)
• Real-time threat detection in shops, offices, stations and public spaces
• Pre-training before fine-tuning on your own camera footage
• Benchmarking detectors on small, distant objects

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 one generic weapon class and no hard negatives; the full dataset has both.

Full dataset and custom data

The full CCTV Weapon Detection Dataset has 1,000 images, YOLO + COCO, classes person, handgun, rifle, shotgun, sniper_rifle. Licence: research $149 / commercial $590. Larger sets, other scenes, camera angles or classes: see custom data or write to contact@simuletic.com.

This free sample is also on Kaggle and GitHub.
