Protect your property without breaking the bank! This guide explores three easy ways to build a home security system using readily available technology and free software. No need for expensive, complex systems.

Repurpose Existing Devices

Transform old smartphones, tablets, or webcams into security cameras. Ideal for monitoring one or two rooms, this budget-friendly option requires minimal setup.

1. Choose a location: Find a spot with power and Wi-Fi access for continuous operation. You may need a mount for phones/tablets to optimize camera angles.
2. Prepare your device: Free up space by uninstalling unnecessary apps.
3. Install surveillance software: Apps like Manything (free for single device, paid options available for cloud storage and multiple devices) or Presence (similar functionality, free with paid cloud storage upgrades) stream live video and offer motion detection alerts. For Windows users, iSpy offers multi-webcam support, recording, snapshots, and customizable alerts. Even Skype can be repurposed (using a dedicated account) by setting automatic answer for incoming video calls.

Utilize Off-the-Shelf Cameras

For convenience, pre-built security cameras offer ease of use and advanced features, albeit at a higher cost.

• Nest Cam: Reliable, intuitive, with motion alerts, two-way audio, night vision, and outdoor options (subscription for advanced features and cloud storage).
• Netgear Arlo: Indoor/outdoor, battery-powered (requires battery monitoring), generous free plan (up to 5 cameras, 7 days cloud recording).
• Canary (Canary Flex): High-quality video streaming, two-way audio, motion alerts, remote alarm triggering (subscription for increased cloud storage).
• Piper NV: High-quality video, two-way audio, excellent night vision, free cloud storage, backup battery.

Modern cameras are user-friendly, requiring minimal technical expertise.

DIY Security System

For the technically inclined, a DIY system offers cost savings and extensive customization.

• Raspberry Pi: A low-cost mini-computer ($40 or less), paired with the official camera module and free software like MotionEye, provides a powerful and flexible foundation. Numerous online tutorials guide the setup.
• Arduino: Another affordable option ($30 or less), offering limitless customization but requiring more technical knowledge than the Raspberry Pi. Online resources provide detailed instructions.

Choose the method that best suits your budget, technical skills, and security needs.
