I do the same here with the Leviton OmniPro 2 combo alarm panel (originally wired to Cartell driveway sensors) and Homeseer and Home Assistant. As far as the false alarms were concerned, you just have to install an commercial grade alarm contact for the gate, depending on the type of gate, I used a a High Security Balanced Magnetic Switch (BMS) contact. I believe the FSPL considering the link budget was around -90dBm. I have done this for a few remote sites, seems to work really fairly well, for the price.ģ) What I have done, was modified an existing 345Mhz wireless sensor where I attached a directional antenna (7 element yagi) at the gate, and installed a wireless repeater, modified with a directional yagi antenna at the main house. This solution, you wire the contact into the I/O Module on the input side, and the module that is installed at the house, you wire in the wireless contact (AUX input) into the output I/O module. If no power, you might have to opt for a solar powered solution. If you have power at the end of the driveway, you can install an Remote I/O IP module (Modbus) and shoot the signal over 802.11 via a point to point configured link. This is the most expensive option of course and in most cases, it is cost prohibitive for some.Ģ). I always opted for hardwired solutions over wireless. Got to Home Depot and rent a trencher (Of course, before you start trenching, call your local utilities (Power, Gas, water, etc.) and have them come out and inspect where the services are some states, this is by law. I tried a few wireless detectors and/or transmitters that advertise 100' to 300' range, and maybe they do in some situations, but I never got more than about 25' with them reliably, ending up wiring the thing all the way into the house.Ĭlick to expand.1200 feet for most wireless alarm devices is way too far considering the FSPL and output power of most devices in the ~300-400Mhz range, you have a few options.ġ). Occasionally a car with high aluminum content slips past the magnetic detector without triggering it, but interestingly, bucks with antlers trigger it reliably. PIR or photoelectric doesn't work for me because of too many false alarms. If you need wireless you could see if Dakota Alert has something suitable. I have it wired to both an audible alarm in the house and an NVR alarm input. I bought one with a short pigtail and use a buried network cable for the ~200 run to the house. I make no recommendation for the seller in the link, it's just a site where I found the product description. The bad news is it's not made any more and I don't have any experience with the "new and improved" model. FAS-CP-3-100-5W Cartell GateMate Free Exit (Probe / Sensor) System :: FAST ACCESS SECURITY The good news is I recommend a magnetic sensor I've been using for a few years. I have good news and bad news as a reply.
