If you’re looking for a budget-friendly and eco-conscious security solution, these cameras are a perfect fit. In this article, we’ll provide a comprehensive guide on how to DIY a solar-powered wireless security camera on your own.

Preparing for DIY Solar Security Camera

To convert a wireless outdoor camera into a solar-powered security camera, you should start by confirming the required materials and power specifications. This step is crucial to ensure the successful operation of your DIY solar security camera.

Required Materials

Before we dive into how to build a solar-powered wireless security camera, let’s prepare the essential materials first.

  1. Security Camera:At the heart of your DIY solar-powered wireless security system, the security camera provides continuous monitoring by harnessing solar energy.
  2. Solar Panel:Choose the right solar panel to efficiently charge your security camera, ensuring an uninterrupted power supply.
  3. Rechargeable Battery:A quickly rechargeable battery is essential for uninterrupted recording and monitoring, allowing your security system to operate seamlessly.
  4. Charge Controller:The charge controller manages the battery’s charging process, ensuring precise charging.
  5. Solar Cables:Use solar cables to interconnect your security cameras, solar panels, batteries, and other essential components for a well-functioning system.
  6. Weatherproof Enclosure: Protect your security camera and battery from prolonged outdoor exposure and harsh weather conditions, guaranteeing the system’s reliability and longevity.

Power Requirement

Understanding the power requirements is a crucial aspect of DIY solar security cameras. Therefore, please consider the following factors before building your solar-powered security camera:

  1. Appropriate camera power (measured in watts) requirements.
  2. Specific Voltage (measured in volts) requirements. For example, if your camera works on 12V, a 12V battery or power source is the best option.
  3. A proper battery type and adequate capacity to store energy for continuous powering.
  4. Solar panel power specifications like power output (measured in watts), size, efficiency, tilt angle, and so on. A 50 watt solar panel should be sufficient for most applications.
  5. Workable Battery Charge Controller to manage the charging process of the solar panel to the battery.

By meeting these energy needs, you’ll be ready to build a dependable and effective security camera system powered by solar energy.

Step 1. Install the Solar Panel

When it comes to installing solar panels, it’s important to consider the placement of the panels as it has a direct impact on power generation. The panels must be installed in a sunny location, preferably towards the equator, to ensure that the batteries are fully charged on sunny days. To optimize sunlight capture, the panels should be installed at an angle equal to your latitude.

It’s also important to ensure that the panels provide more energy than the camera uses so that the camera can obtain enough off-grid power to operate for a sufficient period of time on days when the sun is not bright, cloudy, or rainy.

Step 2. Wire the Components

After installing the solar panel, the next step is to use solar cables to connect the solar panel, solar charge controller, battery, and other parts.

Connect the Battery to the Solar Charge Controller

Choose a cable of appropriate cross-section to connect the solar charge controller to the 12V battery terminals. Please make sure the positive (+) battery terminal is connected to the positive (+) terminal on the solar charge controller and the negative (-) terminal is connected to the negative (-) terminal on the controller to ensure proper operation.

Connect the Solar Panel to the Solar Charge Controller

Next, you need to connect the solar panel to the solar charge controller via cables. Likewise, you need to connect the positive (+) terminal of the solar panel to the positive terminal of the solar charge controller. Then do the same to connect the negative (-) terminals. Then, when the panels begin to receive sunlight charging, the controller will display a “battery charging” sign to tell you whether the connection is correct.

Connect the Security Camera to the Battery Terminals

Finally, you need to connect the security camera to the battery terminals to ensure that the camera can operate with sufficient energy. As usual, ensure that the positive (+) terminal is connected to the corresponding positive (+) terminal on the battery via cables, while the negative (+) terminal is connected to the corresponding negative (-) terminal.

Step 3. Finish and Test

Once the solar security camera system is installed, it will begin harnessing energy from sunlight, enabling you to activate and operate your security camera for continuous monitoring and recording of activities around your property.

However, the installation itself is not the final step. Testing and ongoing maintenance are essential to ensure the system’s long-term performance. Here’s what you need to do:

  • Testing:After installation, conduct outdoor tests day and night to ensure the system’s reliability, including verifying the camera’s solar power source.
  • Battery Monitoring:Regularly check battery status to maintain adequate power reserves and prevent issues.
  • Maintenance:Perform routine cleaning of solar panels and periodic system inspections and adjustments for seasonal changes.

If you encounter any issues or if the system doesn’t work as expected after installation, review the previous steps to identify any missed details. For battery-related problems, consider contacting customer service or support staff for assistance.

Best Alternative to Solar-Powered Wireless Security Camera

Although DIY solar security camera has relatively low economic costs, the complex preparation process leads to increased learning costs and high requirements for hands-on skills. For those who are not good at assembly, purchasing a solar security camera directly may be a better option.

Consider the S120 Solar Wall Light Security Camera, an ideal alternative. This all-in-one solar-powered wireless security camera is effortless to install and includes a built-in solar panel charger, requiring just 2 hours of direct sunlight per day to ensure an adequate power supply.

Moreover, its integrated battery can operate for up to 60 days in power-saving mode. As an outdoor security camera, it boasts an IP65 weather resistance rating, ensuring reliable performance even in harsh conditions. If you’re in need of a solar security camera recommendation, it’s an excellent choice.


In this article, we have learned how to DIY solar-powered wireless security cameras in detail, as well as the materials and power requirements that need to be prepared. Undoubtedly, the most important part of a DIY solar-powered wireless security camera is in the planning and design, which requires you to do a lot of research.

However, if building your own solar-powered security camera is an impossible challenge for you, then you can save time and energy by directly choosing an alternative.
