Oysnid Pool Alarm — Floating Safety Sensor for Inground & Above-Ground Pools, Blue, 85dB Audible Alert & Adjustable Sensitivity

Oysnid Pool Alarm is a battery-powered floating safety sensor that emits an 85dB alert and pairs with an indoor receiver to warn you when something disturbs your pool surface.

Designed for both inground and above-ground residential pools, this bright-blue floating alarm is a no-wires, low-maintenance safety device that detects sudden surface disturbances and notifies you inside the house or on your patio. Built from UV- and corrosion-resistant PC+ABS material, it withstands sun, rain, and pool chemicals and runs on long-life batteries with a low-battery alert so you can rely on it through an entire swim season.

How does the Oysnid floating alarm detect a person or pet entering the water?

The sensor continuously monitors pool surface motion and triggers when a sharp disturbance meets the selected sensitivity threshold. Sensitivity is adjusted with a simple button press so you can balance detection and false alarms. It’s tuned to identify sudden entries while ignoring gradual water movement from wind.

• Adjustable sensitivity via single-button control — no twisting required
• Instant 85dB+ audible alarm at 10 feet to alert occupants indoors
• Calibrated to prioritize sudden, significant surface impacts

Will this alarm cover my entire backyard pool?

One Oysnid unit is rated to protect typical residential pools up to roughly 20'×40'. It floats at or near the waterline, scanning the surrounding surface area for disturbances. For exceptionally large or irregular pools, placement of multiple units improves coverage and reduces blind spots.

• Covers standard single-pool layouts up to 20 feet by 40 feet
• Works in both inground and above-ground pools without modifications
• Use additional units for larger pools or complex shapes

How does the alarm perform in weather and pool-chemical environments?

Constructed from durable PC+ABS, the Oysnid alarm resists UV fading, rain exposure, and chemical corrosion so it keeps functioning season after season. The floating housing sheds water and seals internal electronics, while an audible low-battery beep and flash help you maintain continuous protection.

• UV-, weather-, and corrosion-resistant materials for long outdoor life
• Water-shedding float design protects internal components
• Low-battery indicator beeps and flashes to prevent protection gaps

How easy is setup and everyday use?

Installation takes seconds — place the alarm in the water and power it with the included or recommended batteries. There’s no wiring, no drilling, and no complex configuration: fine-tune sensitivity with a button press and replace batteries when the low-battery indicator activates.

• Battery-powered — no electrician or wiring required
• Quick float-and-go setup for immediate protection
• Simple controls suitable for family use and seasonal storage

Who is this for? Families with young children, pet owners, and homeowners who want an easy-to-deploy layer of pool safety will find the Oysnid Floating Pool Alarm helpful. It’s ideal for anyone seeking a portable, weather-resistant alarm that notifies people indoors and reduces the worry of unattended pool access without complex installation or permanent hardware.
