We recently conducted a comprehensive comparison test of 915MHz wireless video doorbells, including our S76-WL + V3-WL model, to evaluate communication distance, interference resistance, and audio quality. The results confirm what we\u2019ve always believed: our products deliver stable, reliable performance, and any variation in range is due to environmental factors\u2014not product defects.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this blog, we share the test methodology, key findings, and practical installation recommendations. Whether you\u2019re a system integrator, property developer, or end user, this data will help you understand what to expect from 915MHz wireless intercoms\u2014and why FARHD\u2019s S76-WL + V3-WL is a smart choice for your next project.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"test-overview\" class=\"wp-block-heading\">Test Overview<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Date:<\/strong> September 14, 2026<br><strong>Objective:<\/strong> To evaluate the real\u2011world performance of 915MHz wireless video intercoms by measuring maximum effective communication distance, interference resistance, and two\u2011way audio quality\u2014and to compare our S76-WL + V3-WL with competing products.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Equipment tested:<\/strong> Multiple 915MHz wireless video doorbell sets, including our S76-WL + V3-WL, with indoor monitors and outdoor door stations at various battery levels. One competitor device was also included.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Test environments:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Outdoor parking lot on the 1st floor (high\u2011rise corridor, open air)<\/li>\n\n\n\n<li>Indoor office building (factory internal workshop)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Weather conditions:<\/strong> Overcast to cloudy, no direct sunlight, temperature 25\u201332\u00b0C, light breeze.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"test-1-communication-distance\" class=\"wp-block-heading\">Test 1: Communication Distance<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Method:<\/strong> Step\u2011by\u2011step distance pull test. Starting at 20\u2011meter increments, we identified the farthest point at which voice and data packets were stably received by the door station. Three tests were averaged for each environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Wyniki:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">Device Model<\/th><th class=\"has-text-align-left\" data-align=\"left\">Outdoor Parking Lot (m)<\/th><th class=\"has-text-align-left\" data-align=\"left\">Indoor Workshop (m)<\/th><\/tr><\/thead><tbody><tr><td>Wireless Device 1\u20133<\/td><td>-<\/td><td>-<\/td><\/tr><tr><td>Wireless Device 4<\/td><td>20 (2:30 PM) \/ 50 (4:30 PM)<\/td><td>40 (2:30 PM)<\/td><\/tr><tr><td>Wireless Device 5<\/td><td>-<\/td><td>-<\/td><\/tr><tr><td>Competitor Device<\/td><td>50 (4:30 PM)<\/td><td>-<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key finding:<\/strong> The same device, in the same location, achieved only about <strong>20 meters<\/strong> at 2:30 PM when the sun was direct, the parking lot was busy, and traffic on the nearby road was heavy. But at 4:30 PM, under the same conditions, the range recovered to <strong>50\u201360 meters<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Analysis:<\/strong> This variation is not a product defect. 915MHz operates in an open ISM band, and its range fluctuates with real\u2011time electromagnetic and propagation conditions. At 2:30 PM, direct sunlight heated the device, while heavy traffic introduced metal\u2011body multipath reflection, engine and vehicle electronic noise, and co\u2011channel interference from other wireless devices. These factors raised the environmental noise floor and reduced the received signal\u2011to\u2011noise ratio, compressing the effective range to about 20 meters. By 4:30 PM, changes in sun angle, temperature, traffic density, and surrounding wireless activity reduced interference, and the range returned to 50\u201360 meters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Conclusion:<\/strong> The 20\u2011meter result was an instantaneous performance under strong interference, not the inherent communication distance of the product.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"test-2-communication-distance-standard-environment\" class=\"wp-block-heading\">Test 2: Communication Distance (Standard Environment)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Method:<\/strong> Same step\u2011by\u2011step pull test, conducted in a high\u2011rise corridor outdoor environment and an office building indoor environment.
