Versitile installation. - I ordered the plunger style, then realized I didn't have room to mount it as per the instructions! The install was on a door where the hinge side was butted up to a "fake door" with lots of glass. No way to drill a deep 1/4-inch hole in that! Instead, I mounted the unit on the latch side of the door, which changes from a friendly plunge action, to a slightly more harsh sweep-action. So far, it works fine, since the square edge of the door rides the dome shape of the sensor to depress it during door closure. Time will tell how long it lasts. Otherwise, install was fairly simple. 3/4-inch Forstner bit is great, but the 1/4-inch hole for the antenna is trickier. You will need a LONG bit for that (>6 inch), since the chuck of the drill gets stuck in the 3/4 hole. I didn't have one handy, so I used a 3/8-inch blade style with an extension. that works fine, and keeps the 3/4-inch intact to contain the device. Pairing was a snap, and I can confirm it works with the VIVINT panel. I set it up as a "DW21R recessed door contact" and the panel learned the code just fine. Pro-tip: pair and test the device before you install it. :) Review: Perfect for Vivint. - Works great with my Vivint security system. ## Features - Fully concealed wireless door sensor - Provides concealed protection for a door - For residential and commercial applications - Sends low battery condition - Type: Compatible with current 2GIG Wireless receivers ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #224,305 in Electronics ( See Top 100 in Electronics ) #11,579 in Security & Surveillance Equipment | | Customer Reviews | 3.7 out of 5 stars 22 Reviews | ## Images ![iON Digital Plunger Wireless Door Security Sensor, 2GIG (Plunger-2GIG) - Image 1](https://m.media-amazon.com/images/I/51O17gFjtFL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Price!

After repeated attempts (remove from jamb/reconnect) I decided to replace with a DW20R recessed door contact, which works great. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/22526836-ion-digital-plunger-wireless-door-security-sensor-2gig-plunger-2gig](https://www.desertcart.ec/products/22526836-ion-digital-plunger-wireless-door-security-sensor-2gig-plunger-2gig) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-04*
