My ERA-DSTX Detection Range Dropped From 25 Feet to 15Nine times out of ten nothing has failed. A PIR sensor’s usable range is a moving number set by battery voltage, thermal contrast against the background, and the angle at which the target crosses the beam pattern — none of which show up on a thermometer or a tape measure. Work the checks below in order. Most cases resolve at step 1 or step 3.How Far Will My ERA-DSTX Driveway Sensor Really Reach?A PIR sensor doesn’t measure distance — it measures contrast. It sees a target only when that target is meaningfully warmer or cooler than whatever sits directly behind it, and only when the target moves across the lens’s detection pattern rather than straight at it. Change the background temperature, the approach angle, the battery voltage, or the amount of film on the lens, and the same sensor in the same spot will “lose” ten feet of range with nothing visibly different.Is the ERA-DCKIT Wireless Doorbell ADA Compliant?Is the ERA-DCKIT Wireless Doorbell ADA Compliant? gives you the key points, common questions, and the next place to look if you need more detail.Understanding the 12V DC Outputs on Your ERA-DCRX Receiver: A Guide to Zones, Strobes, and BellsIntroduction to the ERA-DCRX Receiver The ERA-DCRX receiver is the heart of your long-range wireless doorbell system, designed for business and warehouse environments.
