When you need a motion-activated door alarm entry alert over the door or other areas, the ERA-PIR-SPK is an excellent choice.

Simply mount this device over a door or in the hallway, and when motion is detected, the built-in speaker plays one of three selected tones.

Entry  Alarm Sound (Motion Activated Door Alarm) from ERA-PIR-SPK Requires No Remote Receiver — Sound Occurs at the Door

Simple to install and requires no maintenance, this unit produces a pleasant chime sound to notify you that someone has entered or passed through the monitored zone.

This is a great product for smaller businesses, retail shops, gas stations, etc., who want to know when a door is opened. Using a Motion Activated Door Alarm Entry Alert Over Door with Built-In Speaker is simple, effective customer service and security at a low cost.

Mount the sensor over the door using the included mounting bracket, adjust the lens angle to cover the area you want to monitor, install the battery, choose the sound (or use default sound), and complete the installation. When the sensor detects the combination of movement and heat (passive infrared, PIR), it triggers the unit to emit a sound.

The product works great for a door that does not stay closed or a hallway area.   This product emits sound from the device using the enclosed speaker.

What makes it different from its sister product, the ERA-PRDCR, is that with THIS UNIT, a signal is not sent to a remote location; instead, the sound comes from the unit itself.

With the ERA-PRDCR, the sensor sends a remote radio signal up to 4,000 ft. away to the chime receiver, where the sound is heard.

Mounting the Height of the Entrance Alert Above Door Affects the Coverage Zone

Another feature of this product that distinguishes it from other PIR sensors on the market is the simple, but unique mounting bracket.

The mounting bracket is an aluminum bracket that allows you to tilt the sensor lens approximately 160 degrees to ensure the invisible beam covers the area you want to pick up.

For example, in a retail store, you may want to rotate the unit so that the lens is angled towards the door to minimize “bleeding” into the area with a lot of foot traffic.

ERA PIR Monitored Zone Size

This table shows the size of the monitored zone created.  As the mounting height increases, the width and depth of the monitored zone increase.

The unit was designed to have a narrow zone depth in order to eliminate bleeding into areas you do not want to monitor, and false triggers.

In addition to the size of the zone, adjusting the angle of the sensor angle will also help.

Got this for an office. Easy to install, works as described and arrived super fast. I highly recommend it. Thank you

Entry Alert

The device remains tamper proof by its good design and by its location above the door frame. It’s also unobtrusive and leaves the side walls free for shelving and pallets. Finally a neat, battery operated, alert with pleasant ring tones that allows businesses to know that customers have entered the premises. Customers also feel welcomed and announced. (Just a nice Ding dong not a damn burglar alarm). How easy!

Thank you very much for taking the time to write us a review.

Yes, this is a great entry alert! It's unobtrusive and battery-operated, so it's great for businesses. The ringtones are also pleasant, so customers feel welcomed and announced. Easy to use!

As expected

The battery-operated ERA-PIR-SPK motion-activated over-door entry chime has been functioning exactly as expected. It is basic, but fairly easy to set up and install. And it's consistently letting us know when someone enters through the double doors around the corner. We turned down the volume as our office is fairly quiet most of the time. It doesn't have the prettiest sounds. We went with the standard electronically reproduced "ding-dong" you've heard in countless convenience stores, but it's not an ugly sound, and there doesn't seem to be anything better sounding on the market unless you want to pay double. Seemed like a good price and easy install to match our simple needs.

Love our new doorbell!

We are using our new doorbell as security at a gift shop entrance that is out of the line of vision for our cashier. That way we know someone has come in the shop. The bell (ding,dong) is loud enough, but not obnoxious. Easy to install. A great product.
