Elk-M1 G and new house build

[apostolakisl]

How is electric service provided at the gate? I'm thinking if your friend has to cut a trench from the house to the gate to get power there, then the same trench might be suitable for low voltage or fiber. On the other hand, if gate power comes from a pole across the street, then a trench just for the low voltage might make the wireless solution more practical.

I agree with the above.

Also, there would be a great expense in running electric wire 2000 ft trench not even considered. For example, 2000 ft, 10 amps, 120v, 3% voltage drop requires between 0 and 00 gauge. 2000 ft of 0 gauge is $$$$. Maybe you don't mind a bigger voltage drop or figure you won't use hardly any amps out there. You could run 10 awg wire if you were planning on staying under 1 amp with 3% v drop. But one amp is only 120watts (minus your 3%).

I am curious, what needs to be reset? In my experience with IP devices both wired and wireless, resets fix routing issues, not rf connections. You either get a good enough signal, or you don't, resets have never changed that.

We have sites that are sending 232 and 485 from gates and readers to head end equipment, and there's usually some sort of conversion first to migrate the data based on distance being sent, such as from the hardware, reader, controller, etc. then to the modem/transmitter, then via a Yagi/directional to another modem/receiver, then brought into the head end, either to a PC or another system I/O board. Typically it's most common for us to be sending wiegand and serial data across, however we've also had to send 485/422 as well as the access control setups have migrated to perimeter fringe RF devices rather than hardwired, usually because there's the pavement or distance factor involved.

Usually any power blip or heavy storm that goes through, we have some sort of issue with readers dropping offline or data issues, corruptions, etc. Usually requires a reset of some sort, with the worst is re-syncing the devices we're using. YMMV.

You should talk to this guy about your gate solution. The unit he has seems to be exactly what you need.

Sounds like you are sending a great distance. A plain old high quality wireless AP will hit 1000 feet with clean line of sight. A simple directional antenna on a high end wireless AP will go 2000 plus feet and function just as well as the computer I am on right now over my office wifi. Unless you have a flaky AP (and there are plenty of them) it shouldn't drop. I am quite familiar with flaky AP's and routers which for reasons unexplained need regular reboots. These quickly find their way back to point of purchase or in the heap of "maybe I'll need to salvage a part from this someday" box. My wife never believes me that I ever salvage parts, but I do, I swear.
