How Do You Run Underground Security Camera Wires

If you’re planning to install underground security cameras, then you know how important it is to run the wires correctly. Security camera wires are crucial because they connect your cameras to their power source and recording device, ensuring that your system runs smoothly. The last thing you want is to have a faulty connection or exposed wires that can be tampered with or damaged by external factors. In this guide, we’ll walk you through the steps of running underground security camera wires correctly and help you set up a reliable and secure surveillance system for your property.

Why Run Underground Security Camera Wires?

Before we dive into the nitty-gritty of how to run underground security camera wires, let’s first understand why it’s necessary. Unlike wireless cameras, which can be prone to signal interferences and hacking, wired security cameras provide a more reliable and secure connection. Additionally, underground wires are concealed from view, making it harder for intruders to tamper with them or cut them off.

Moreover, in some cases, building codes may require the use of underground wiring for outdoor installations. This is because above-ground wires can be hazardous and prone to damage from weather conditions. Running underground security camera wires can also help you avoid potential legal issues in the future.

Locating Underground Utilities Before Digging

Before you start digging to bury your security camera wires, there’s an important step you shouldn’t overlook. You have to figure out how to locate underground utilities yourself or have a professional do it. It’s essential because you want to avoid accidentally cutting into your water, gas, or electrical lines. This could lead to a service disruption, pose safety risks, or even result in fines. Even if you’re only digging a few inches deep, it’s a good idea to understand where these utilities are. In the U.S., you can call 811 to have your utility providers mark the location of lines for free. Alternatively, use a utility locator tool or hire a professional if you’re unsure about doing it yourself.

What You’ll Need

Before you get started, make sure you have all the necessary tools and equipment. Here’s a list of what you’ll need:

  • Security cameras and their corresponding cables
  • A power drill with masonry bits
  • PVC conduit pipes
  • Electrical tape
  • A shovel or trenching machine
  • Wire strippers and wire connectors
  • Waterproof junction boxes for outdoor installations
  • Label maker (optional)

Step 1: Plan Your Camera Locations

The first step is to determine where you want your cameras to be installed. Take a walk around your property and identify the areas that need surveillance. Keep in mind that the cameras should have a clear view of your property’s entry points and any potential blind spots.

Once you’ve identified the locations, draw a rough diagram of your property and mark these areas. This will serve as a guide when you start running the wires.

Step 2: Choose Your Route

Next, decide on the route you’ll take to run the wires. It’s important to choose a path that is not obstructed by any structures or landscaping features. The route should also have enough space for you to dig a trench and lay the conduit pipes.

It’s recommended to avoid running the wires next to electrical lines, as this can cause interference with your cameras’ signal. If you must cross an electrical line, make sure to do so at a right angle.

Step 3: Dig the Trench

Using a shovel or trenching machine, dig a trench along the chosen route. The depth of the trench should be about 18-24 inches deep to ensure that the wires are buried deep enough. Make sure to call your local utility company before digging to avoid hitting any underground cables or pipes.

Step 4: Lay the Conduit Pipes

Once you’ve dug the trench, it’s time to lay down the conduit pipes. These pipes will protect and conceal your security camera wires. You can purchase PVC conduit pipes from any home improvement store.

Start at one end of the trench and feed the pipe into it until you reach the other end. Use a mallet or hammer to secure the pipes in place. If you need to make any turns, use pipe elbows to bend the conduit pipes.

Step 5: Run the Wires

With the conduit pipes in place, it’s time to run your security camera wires through them. Start at one end and feed the wires through until they reach their designated locations. Make sure to leave some slack at both ends, in case you need to make any adjustments.

Step 6: Connect the Wires

Once the wires are in place, it’s time to connect them to your cameras and recording device. Use wire strippers to remove the insulation from the wire ends, and then twist together the matching colored wires. Use waterproof wire connectors or electrical tape to secure the connections and prevent any water damage.

Step 7: Test the Connection

Before burying the wires, it’s crucial to test the connection to ensure that everything is working correctly. Plug in your cameras and recording device and make sure they are receiving power and transmitting footage. Use a label maker to mark each wire with its corresponding location for future reference.

Step 8: Bury the Wires

With everything in place, it’s time to bury the wires. Use a shovel to cover the trench with soil and pack it down firmly. For added protection, you can also lay some gravel or sand on top of the wires before covering them with soil.

Extra Tips for a Successful Installation

  • If you’re installing outdoor cameras, make sure to use waterproof junction boxes to protect the connections from moisture and harsh weather conditions.
  • Consider using cable ties to secure the wires inside the conduit pipes, preventing them from moving around or getting tangled.
  • If you’re not confident in your DIY skills, it’s always best to consult a professional for installation. This will ensure that everything is done correctly and save you from potential headaches in the future.
