The problem we kept hearing about was security systems getting completely neutralized before they ever sounded an alarm—someone drives up with a jammer, kills the WiFi and cellular link, and by the time anyone notices, the damage is done. So what this does is give you a heads-up the moment that interference starts, not after the connection drops completely, which is a crucial difference when you're trying to catch someone in the act.
It monitors for jamming signals across the usual suspects: WiFi at 2.4 and 5GHz, mobile bands, plus 433MHz and 868MHz which a lot of home alarm sensors use—pretty much the full spread you'd see form a commercail jammer. The detection range works out to about 20 meters or so for a 300mW jammer, which covers a decent-sized room or office, though it'll pick up a weaker 20mW transmitter from roughly 15 meters away. Sensitivity is adjustable too, with a background noise filter that helps cut down false triggers in busy environments, and that's something people usually appreciate after the first week of instalation.
But the anti-cut protection is actually what most buyers ask about after they've had a wired detector physically disabled. It doesn't just rely on the power line staying intact—the relay output (1.0A, NO/NC) will trigger an alert even if someone severs the cable, which is a detail that's easy to overlook until you need it.
You get an 8-LED visual alert system that lights up based on which band is being jammed, so you're not just guessing what's happening—it'll tell you whether it's the WiFi or the 433MHz line that's getting hit. 5. Power requirment are 12-24V DC at 150mA, so it'll run off most security system power supplies without any issue, and the whole unit is 116×70×33mm (basically a small box), weighing 170 grams, which makes it easy to mount behind a panel or near teh control board. We usually have stock on these, but check lead time if you need more than 50 units.
We typically require a MOQ of 50 units for the PTC-UJ2, but we can negotiate smaller quantities for first-time orders or sample requests.
Lead time is usually 7-10 business days for in-stock units. Custom orders or larger quantities may take 2-3 weeks, depending on your location.
Yes, each unit is CE and RoHS certified. We provide a Certificate of Conformance with every shipment, and additional test reports are available on request.
Absolutely. The PTC-UJ2 has a variable sensitivity adjustment with a background noise filter, so you can tweak it to avoid false alarms in noisy areas while still catching low-power signals.
It ships in anti-static packaging with foam padding. For storage, keep it in a dry place between 0°C and 50°C, with humidity under 90% non-condensing, to maintain performance.
