Hikvision DS-PDWL-E-WE AX PRO Wireless Water Leak Detector

The Hikvision DS-PDWL-E-WE is the AX PRO water leak detector — a small IP66 unit that reports the moment water reaches it, on the floor or through the included probe, long before a leak has become a flood.

Why a leak detector belongs on an intruder-alarm panel

A burst pipe under a sink, a failed washing machine hose, or an overflowing bath can do more damage to a property than most break-ins — and it usually happens while nobody is there to notice. Adding this detector to an existing AX PRO system means one app, one panel and one set of notifications cover both security and water damage, at the cost of a single extra sensor rather than a separate monitoring system.

Two ways to detect water

It works standalone, sitting flat on a floor where water is likely to pool — under a boiler, beside a washing machine, in a plant room — or with the included probe extended into a tighter space such as under a sink or behind a toilet. Either way, contact with water completes the circuit and triggers an immediate alarm.

Built for a wet environment

Rated IP66, so the detector itself can sit somewhere genuinely damp without the electronics being at risk — appropriate for a utility room or a bathroom, not just a dry cupboard.

Three years on one battery

A single CR2450 cell gives up to three years standby — worth knowing since these detectors often end up somewhere easy to forget, like behind a washing machine.

Radio built for alarms

Tri-X two-way wireless at 868 MHz, AES-128 encryption, frequency hopping, free-space range 1.2 km. The panel confirms every transmission — worth having on a sensor that may sit somewhere rarely checked. Enrol by power-up, remote ID or QR code.

Tamper front and rear

Cover and backplate are both monitored. Temperature and signal strength indicators help confirm the position before you leave it in place.

Worth knowing before you order

It detects water, not a slow drip building up unseen. Site it where water would actually reach it — flat on the floor at the lowest point of a room, or with the probe positioned in the specific tight spot you're protecting.

It needs an AX PRO panel. A Tri-X 868 MHz device for the AX PRO system only — not standalone, not compatible with other manufacturers' panels.

Not included in any kit. Add it individually wherever a leak would be costly — kitchens, bathrooms, utility rooms, plant rooms, anywhere with a boiler or a washing machine.

Frequently asked questions

Where should I put it?

Flat on the floor at the lowest point near the risk — under a boiler, beside a washing machine or dishwasher — or use the included probe to reach a tighter space like under a sink.

How long does the battery last?

Up to three years on one CR2450 cell.

Is it waterproof itself?

Rated IP66, so it can sit in a genuinely damp location without the electronics being at risk.

Does it need the probe?

No — it works standalone on the floor. The probe is for reaching a specific tight space.

Does it work with other alarm panels?

No. It is a Tri-X 868 MHz device for Hikvision AX PRO panels only.
