arlo essential indoor 2nd gen camera is making a constant high-pitched whining noise, it's driving me nuts.

Diagnosis

The high-pitched whining noise emanating from your Arlo Essential Indoor Camera (2nd Gen) is a phenomenon known as "coil whine." This occurs when the electrical current passing through the camera's internal inductors or transformers causes the copper coils to vibrate at a frequency audible to humans. In the 2nd Gen Essential model, this is typically caused by a failure in the potting compound or a loose winding in the DC-to-DC converter circuit that steps down the voltage for the camera's processor and Wi-Fi chip. This is a hardware-level defect, not a software glitch. You can confirm this by moving the camera closer to your ear and noticing the sound is constant regardless of whether the camera is recording or in standby mode. If the pitch changes slightly when the camera's IR LEDs click on for night vision, it confirms the noise is tied to the power draw of the internal circuitry. Because the components are surface-mounted and sealed within the plastic chassis, there is no external adjustment that can stop the physical vibration of the coil.

How to Fix It

Because this is a physical hardware failure within the sealed mainboard, there is no manual calibration or setting that will stop the noise. The only permanent solution is a hardware replacement. Follow these steps to secure a replacement unit:

1. Document the Noise: Use a smartphone to record a clear video of the camera. Place the phone's microphone directly against the camera housing to capture the high-frequency whine, as standard recordings often filter out these frequencies.
2. Locate Your Serial Number: Find the S/N on the sticker located on the bottom or back of the camera unit. You will need this exact alphanumeric string for the warranty claim.
3. Check Warranty Status: Navigate to the Arlo account portal and verify your purchase date. The Essential 2nd Gen carries a standard limited warranty that covers manufacturing defects like coil whine.
4. Initiate an RMA: Contact Arlo Support via their official portal. Specifically state that the device is experiencing "audible coil whine from the internal power supply," as this terminology helps the support agent categorize it as a hardware defect rather than a "noise complaint."
5. Prepare for Shipping: Once the Return Merchandise Authorization (RMA) is issued, pack the camera securely in its original packaging or an equivalent padded box to prevent transit damage, which could void the replacement claim.

If That Didn't Work

If you are out of warranty or cannot get a replacement, try these mitigation strategies:

• Change the Power Source: Swap the provided USB power adapter for a high-quality, name-brand 5V/2A power brick. While the whine is internal, some low-quality power adapters introduce "dirty" power (electrical noise) that can exacerbate the vibration of the internal inductors.
• Reposition the Unit: Move the camera away from reflective surfaces like glass or polished tiles. High-frequency sounds bounce off hard surfaces, creating an acoustic amplification effect that makes the whine seem louder than it actually is.
• Apply Acoustic Dampening: If the camera is sitting on a hard shelf, place a small piece of adhesive foam or a rubberized mat underneath the base. This prevents the shelf from acting as a sounding board that amplifies the internal vibrations.
• Adjust Placement Height: Mount the camera higher on the wall. High-frequency sounds are highly directional; moving the device above head level often pushes the noise floor outside of your immediate auditory range.

Heads Up

• Avoid Disassembly: Do not attempt to open the camera casing. The 2nd Gen Essential uses plastic clips and hidden screws that are easily stripped, and opening the unit immediately voids any remaining warranty.
• Avoid "Quick Fix" Sprays: Never spray electronic cleaners or lubricants into the vents of the camera to stop the noise; this can cause a short circuit on the mainboard.
• Power Cycle Regularly: If the whine increases in pitch over time, perform a hard reset by unplugging the device for 30 seconds to clear the capacitors.
• Check for Heat: Feel the bottom of the camera. If the whining is accompanied by excessive heat (too hot to touch), the inductor may be failing completely, posing a potential fire risk. Power down the device immediately.
