Understanding Alarm.com PoE Cameras and Their Benefits

What Is a PoE Camera?

Power over Ethernet (PoE) technology allows both power and data to be delivered to a device over a single Ethernet cable—typically Cat5e or Cat6. This eliminates the need for a separate power outlet near the camera, making installation cleaner, safer, and more flexible. Alarm.com’s line of PoE cameras, such as the ADC-V723 or ADC-V724, leverage this technology to provide high-definition surveillance with minimal cabling clutter. These cameras are designed specifically for integration with the Alarm.com cloud platform, enabling remote access, real-time alerts, video history, and automation with other smart home devices like door locks, lights, and thermostats.

Unlike traditional analog cameras or Wi-Fi models, PoE cameras offer consistent performance without signal drops or bandwidth congestion. Because the data travels over a wired network, you avoid common wireless issues like interference from microwaves, walls, or neighboring networks. This makes PoE ideal for outdoor installations, large properties, or areas where Wi-Fi coverage is spotty.

Key Advantages of Alarm.com PoE Cameras

• Reliability: Wired connections ensure stable video streaming and uninterrupted recording.
• Scalability: Multiple cameras can be daisy-chained or connected via a PoE switch, allowing easy expansion.
• High-Quality Video: Most models support 1080p or 4K resolution with wide dynamic range (WDR) for clear footage in challenging lighting.
• Remote Access & Alerts: View live feeds and receive motion-triggered notifications via the Alarm.com mobile app or web portal.
• Cloud & Local Storage: Choose between cloud-based video history (with subscription) or local storage via an NVR (Network Video Recorder).
• Smart Home Integration: Trigger lights, sirens, or doorbells when motion is detected using Alarm.com’s automation rules.

Example: A homeowner in Colorado installed two ADC-V724 cameras at their front and back doors. Using PoE switches in their garage, they connected both cameras to their existing Alarm.com system. Within a week, they received a motion alert at 3 AM—a raccoon was rummaging through their trash. Thanks to the camera’s night vision and two-way audio, they scared it off remotely without leaving the house.

Tools and Materials You’ll Need for Installation

Essential Hardware and Equipment

Before you begin, gather all necessary tools and materials. Having everything on hand prevents mid-installation delays and ensures a professional-grade setup.

• Alarm.com PoE Camera (e.g., ADC-V723, ADC-V724, or newer model)
• PoE Switch or PoE Injector – Choose based on your network setup:
  • PoE Switch: Best for multiple cameras; connects directly to your router.
  • PoE Injector: For single-camera setups; connects between your router and camera.
• Ethernet Cable (Cat5e or Cat6) – Length depends on distance from switch to camera. Use outdoor-rated cable for exterior installations.
• Mounting Hardware – Usually included with the camera (screws, anchors, mounting bracket).
• Drill with Drill Bits – For creating pilot holes in walls or soffits.
• Screwdriver (Phillips and Flathead) – For securing the camera and adjusting the mount.
• Stud Finder or Tape Measure – To locate structural supports and ensure precise placement.
• Fish Tape (Optional) – Useful for running cables through walls or ceilings.
• Network Cable Tester – To verify cable integrity before connecting.
• Smartphone or Tablet – For scanning QR codes during setup and accessing the Alarm.com app.

Optional but Recommended Items

• Surge Protector – Protects your PoE switch and camera from electrical spikes, especially in outdoor setups.
• Cable Management Clips or Conduit – Keeps wires organized and protected from weather or tampering.
• Weatherproof Junction Box – If terminating the cable outside the wall (e.g., in soffits).
• Label Maker – Label cables at both ends for easier troubleshooting later.

Tip: Always use shielded Ethernet cables (STP) in areas prone to electromagnetic interference (e.g., near HVAC units, power lines, or metal structures). This reduces the risk of signal degradation and ensures consistent video quality.

Step-by-Step Installation Process

Step 1: Choose the Optimal Camera Location

Proper placement is critical for effective surveillance. A poorly positioned camera may miss key activity or be vulnerable to tampering. Consider the following:

• Field of View: Aim for a 90–120° coverage angle. Avoid pointing the camera directly into the sun or bright lights to prevent glare.
• Height: Mount 8–10 feet above ground to deter vandalism while capturing facial details.
• Entry Points: Prioritize doors, windows, garages, and driveways.
• Overhangs and Eaves: These provide natural protection from rain and debris.
• Wi-Fi Signal (for setup): Ensure your smartphone can connect to your home network during configuration.

Example: A homeowner in Florida mounted their ADC-V723 under the front porch eave, angled slightly downward to cover the walkway and mailbox. The 10-foot height prevented tampering, and the overhang protected the camera from rain and direct sunlight.

Step 2: Run the Ethernet Cable

This is often the most labor-intensive part. Plan your cable route carefully:

• From the PoE switch/router location to the camera mount point.
• Use existing pathways (e.g., attic, basement, crawl space) to minimize drilling.
• If running through walls, drill a small hole (¼ inch) and use a fish tape to pull the cable.
• Leave 6–12 inches of slack at both ends for connections.
• Seal outdoor holes with silicone caulk to prevent moisture intrusion.

Tip: Label the cable at both ends with the camera name (e.g., “Front Door”) to avoid confusion during setup or future upgrades.

Step 3: Mount the Camera

1. Attach the mounting bracket to the wall or soffit using the included screws and anchors. Use a level to ensure it’s straight.
2. Thread the Ethernet cable through the bracket’s opening (if applicable).
3. Connect the cable to the camera’s Ethernet port. Some models have a weatherproof rubber grommet—ensure it seals properly.
4. Snap or screw the camera into the bracket. Tighten securely but don’t over-torque.
5. Adjust the camera angle using the pivot joint. Aim it slightly downward to capture faces and activity.

Pro Tip: For soffit installations, consider using a soffit vent cover as a mounting surface. It blends with the architecture and provides a flat, stable base.

Step 4: Connect to the Network

Now it’s time to power up the camera:

• Connect the other end of the Ethernet cable to your PoE switch or PoE injector.
• Plug the PoE device into a power outlet.
• Connect the PoE switch/injector to your router using a standard Ethernet cable (if using a switch).
• Wait 1–2 minutes for the camera to boot up. Most models will show a blinking LED (usually green or blue) during initialization.

Note: If using a PoE injector, connect one Ethernet port to your router and the other (labeled “PoE Out”) to the camera cable. The injector itself requires power via an AC adapter.

Configuring the Camera in the Alarm.com App

Step 1: Add the Camera to Your Account

Open the Alarm.com mobile app (iOS or Android) or log in to the web portal. Follow these steps:

1. Tap “Devices” > “Add Device”.
2. Select “Camera” > “PoE Camera”.
3. Choose your camera model (e.g., ADC-V724).
4. Scan the QR code on the camera’s label or manual. This links the device to your account.
5. If no QR code is available, manually enter the camera’s serial number.

The app will search for the camera on your network. Once found, it will display a live preview.

Step 2: Customize Camera Settings

After adding the camera, configure the following in the app:

• Name: Assign a descriptive name (e.g., “Back Gate Camera”).
• Motion Detection Zones: Draw areas on the screen where motion should trigger alerts (e.g., driveway, front steps). Exclude busy areas like trees or roads.
• Video Quality: Adjust resolution (1080p recommended) and frame rate (15–30 fps). Higher settings use more bandwidth and storage.
• Night Vision Mode: Choose between IR (infrared) and full-color (if the camera supports it). IR is ideal for pitch-black conditions.
• Two-Way Audio: Enable if you want to speak through the camera (e.g., to deter intruders).
• Recording Schedule: Set continuous recording or motion-triggered clips. Cloud plans start at $9.99/month for 10GB of storage.

Example: A homeowner in Texas set their ADC-V723 to record only when motion was detected within a 10-foot radius of the front door. This reduced false alerts from passing cars and saved cloud storage.

Step 3: Test and Optimize

Before finalizing the setup:

• Walk in front of the camera to trigger a motion alert. Confirm you receive a notification.
• Check the live feed for focus, lighting, and field of view. Adjust the camera angle if needed.
