Quick Camera System

Ever needed a simple and easy-to-use surveillance camera system for your Unity projects? With Surveillance Camera System, you can quickly set up and manage multiple cameras in your scene with a straightforward editor interface. Whether you're looking for a base to modify and expand upon, or simply want to add cameras to your worlds. this system has you covered.

It includes gizmos to visualize what each camera sees etc.., and a simple editor interface to preview the camera view or even assigning cameras automatically, making it perfect for anyone, from beginners to advanced users.

UPDATE 1.1.1 Fixed the issue where cameras weren’t showing for new joiners. Turns out, I had some "zombie" code that I forgot to integrate, dumb mistake on my part. I’ll be more careful next time!

How to Use

1. Drag and drop the Camera System Prefab into your scene.
2. Click "Assign Surveillance Camera References" to automatically detect and add all cameras in the scene (or manually drag them into the list).
3. To remove all assigned cameras, click "Clear Surveillance Camera References."

Important Note

This system adds another camera to your scene, which could have a performance impact on lower-end platforms. If the camera is not being used, make sure to disable it to prevent unnecessary resource usage.

How to Use (Extended)

Setup

1. Add the Camera System

• Drag and drop the "Camera System" prefab into your scene.
• Duplicate the cameras as needed.

1. Assign Cameras to the Navigator

• In the Surveillance Camera Navigator, assign the cameras manually or
• Click "Assign Surveillance Cameras References" to automatically detect all cameras in the scene.
• If needed, use "Clear Surveillance Cameras References" to reset the list.

Configuring Cameras

• Surveillance Camera → The "real" active camera (must be assigned for the system to work).
• This camera must have a Render Texture assigned.
• The Render Texture must be in a material used by the screen.
• Surveillance Cameras → List of all available cameras.
• Current Camera Index → Tracks the selected camera.
• Camera Name Text UI → Displays the camera’s name & description (uses TextMeshPro).
• Editor Gizmos → Enables camera frustum visualization in the editor.

Surveillance Screen Setup

1. Use a pre-made camera screen (e.g., Tablet or Monitor) or create your own:

• Add your 3D model.
• Attach the "Camera Screen" script.
• Ensure the UV mapping respects the 16:9 aspect ratio (default).

1. Configure the Camera Screen Script:

• Screen Material → Assign the material containing the Render Texture.
• Material Index → Select the correct material slot to replace with the Render Texture.
• Screen Mesh Renderer → Assign the mesh renderer of your screen.
• Use "Auto Setup" for automatic configuration (you must still assign the screen material and material index manually).

Switching Cameras

• Use "Previous Camera" and "Next Camera" buttons to cycle through cameras.
• (Only works if a Surveillance Camera is assigned and enabled.)
• For custom buttons:

1. Use TextMeshPro UI Buttons.
2. In the "On Click" event, click "+".
3. Drag & drop the Navigator into the event slot.
4. Select "UdonBehaviour.SendCustomEvent (string)" and enter:

• "PreviousSurveillanceCamera" or "NextSurveillanceCamera"

• If you're using U# scripting, the navigation methods are public and can be called directly.
