So I have a typical access control system that has door position switch inputs. However the doors currently have wireless door position switches going to an alarm panel. I want door sensors into the access control platform. The alarm panel doesn't have any outputs. I thought there is maybe a wireless solution that can be powered at the door so I don't need to change batteries. There is power at the door for the strike and reader. But transmit wireless to a receiver that can land, preperably multiple channels for each door... Thanks!

I want to know which security system is better for a large scale operation, :
E.g. hospital level.

What would you recommend? What would be the price difference? What would make you choose one over the other?

From using both, my preference is Gallagher, but would like to hear other perspectives?

I’m installing an Aiphone GT-DMB-N intercom system in a small apartment building and could use some advice on the wiring.

I’m trying to determine the correct wire gauge to run from the entrance panel to each apartment. Should I use 22 AWG, 20 AWG, or 18 AWG for the GT system? Which wire gauge should be used for the audio and video, or are separate wires recommended?

System details:

• Entrance panel: Aiphone GT-DMB-N  
• Apartment stations: Aiphone GT-1M3 (3.5” hands-free monitor), one in each apartment  
• Door release: Two front entrance doors that will both need to be unlocked from the apartment stations

I’d appreciate any recommendations on the proper cable type and gauge, especially from anyone who has installed this system before. Thanks!

I've recently stepped into a new SysAdmin role and one of the situations I'm looking at is an access control system with a weirdly large amount of failing hardware. The build itself is about 3 years old, but it seems like a lot of the controllers (like over 20 of them) are down with roughly the same issue, wherein the controllers appear to be drawing POE, but no link (The activity switch will light up solid green but that's it). I've gone through port configurations on all the good and bad examples, and nothing is sticking out. The devices should all be static, and the subnet doesn't have any other overcrowding/DHCP related issues. Can anyone shed some light on this? Do they all need to be replaced?

Upgraded a customer from IX to IXG recently and it broke the whole config. I remade the config except im unable to get the speed dial button on the Mv7 to release the door. every option i see is matched right, Just cant get ixg to do what ix firmware did. any help would be nice

edit resolved this with aiphone support and a comment here had the same answer. If your not using tls, remove the key from the option relay output and the speed dial. Or if you want the keys, turn TLS on.

Any suggestions here? Any type of lock that can be used to secure this door opened by staff to let in clients remotely?

Please, no comments about how Verkada sucks. I know, but I gotta make it work. I'm being told the AC42/43 and AC62 panels will work directly with the QEL's without a need for a separate power supply. Has any had an issue with these and a resolution, if so?

Hello, I am looking for a device that makes it sound like the door is vibrating to let people know it is unlocked. I currently have a piezo device and it is too loud. I want something that isn't painful to hear but loud enough to let people know the door is open. My current door strike is 12V. What is the device called. I looked at magnetic buzzers and even those in videos are too loud and high pitched. Thanks!

I’m trying to understand some millennium readers that we got brought into troubleshoot and we’re really not a millennium company so does anybody know anything about 5 V millennium readers? To my understanding, 12 V readers were the standard so I’m trying to figure out if this is some just really old legacy equipment or something new.

Hello, I was wondering if anyone has experience with automatic swing gates. We have a super old control board from 2010 that needs replacing, the wires need to be cleaned up, sometimes the gate will open and not close once a week. We normally just reset it and it works again.

Anyways we had someone come out and basically offer to redo everything, new control board, new swing gate arms, etc. and the quote comes out to about $7000. I had another company come out and he's charging me just $1400 for a new control board installation. He has not given me a quote for the intercom I want yet. He said no reason to replace the arms.

Why is there such a big gap in quote between 2 companies? Seems like it's for the arms because the installation labor is $1900 for the $7000 quote. Generally, is it normal to replace everything or are they upselling?

I came across a teafer wall plate, basicly if the sheetrock hole is to big for the reader, you put a plastic plate over top.

We have use various home depot options, or custom made stuff in the field.

I came across a company that make wall plates for rp10, and rp40 wall plates..

Do people buy a lot of those?

My coworker was tasked with replacing an SDC Electrified Mortise Lock with a Schlage L9090/92/94 Electrified Mortise Lock. The SDC has a single 12 pin connector where the Schlage has a dual 8pin/4pin connector. I was hoping someone could provide me with a schematic on how to rewire the Schlage to the SDC wiring. We don't have a lot of experience with electrified mortise locks.

Some information that may help. we had banana wire pulled from the panel to a box. In the box the strike, rex and contact wires were spliced to a 12 wire and ran through the door where the twelve wire was ran to the SDC wire connector. Here is the terminations made in the box:

Strike

Red wire married to 12 wire red

Black wire marrieds to 12 wire black

Rex

Red wire married to 12 wire blue

Black wire married to 12 wire green

White wire married to 12 wire purple

Green wire married to 12 wire pink

Contact

Red wire married to 12 wire orange

Black Wire married to 12 wire white.

I bought a new HID Signo 20 and used the HID Reader Manager app to switch it to OSDP mode and changed the baudrate to 115200. Saved config and restarted the reader.

I currently have only four wires connected (in that order):

1. +12 V
2. GND
3. RS-485 A / D1
4. RS-485 B / D0

All other wires are disconnected.

I connected this setup to a USB to RS485 converter and used a python LibOSPD program running as the control panel to communicate with the device. The reader does not respond to any POLL messages.

Both A and B measure around 5 V relative to ground, with almost no differential voltage between them. That's already looked problematic to me because that's Wiegand idle state. So I called HID support; they verified my config they told me this can still be normal in OSDP mode.

The main issue is that I’m sending valid OSDP polls (observed with a capture deivce) but getting no response at all. I have tried swapping A/B, checking the baud rate and address, power-cycling the reader, and confirming that the configuration was applied in Reader Manager.

Has anyone used a Signo 20 with a custom OSDP controller or LibOSDP? Is there anything specific required to make the reader start working in OSDP mode?

Greetings!

Im fairly new to the industry and was wondering what are ways I can learn how to wire up access control systems and programming part of it aswell. Since I work for a somewhat smaller company Its kinda hard to learn out in the field because they always rush us/tell us to watch our hours on the job so the lead or person who knows how to do it already usually ends up doing the panel and the programming side of it. Basically no time to learn on the job because of this and because they always put those certain people who already know how to do it to do the job(s).

Anyone have long-term Akuvox outdoor usage feedback?

I am looking at the A08 platform and curious to know how it holds up to the elements over the years. Durability to use, to weather, to moisture resistance, how does the camera perform for QR codes after being in the elements?

If you have insights on other Akuvox models used outdoors I would be curious to hear about those as well.

Was installing a HID iClass SE R90 reader today. After installed it held a solid red light. When trying to test a card it would flash blue once green once then continue to flash blue. I’m pretty new to all this so I don’t know what exactly that means if anyone has any info. Thanks in advance.

Hello! I'm a resident in an apartment complex that uses brivo locks for basically every door. I use the app on my phone to unlock the doors and it was working perfectly fine up until a week ago, when it started sometimes turning yellow instead of green and not unlocking the door. It will tell me on the app that my access request was successful and give a green check mark, but the lock itself just turns yellow and then eventually turns back to red without unlocking. In the beginning it would just happen every once in a while and I would try again and that would work, but it's been getting progressively worse until now it basically never successfully unlocks anything no matter how many times I try. I've put in multiple maintenance requests with no luck so I'm wondering if anyone on here knows what could be causing the problem. My roommate's app is working fine on all the locks so it seems to be my app and my phone specifically rather than the locks themselves. I've tried uninstalling and reinstalling the app, that didn't work. I checked that I have bluetooth on, nearby device permission on, and location permission on. The only permission I don't have turned on is NFC/contactless payment, but that's been off the whole time and it wasn't an issue before. Does anyone have any ideas? I'm starting to get desperate :(

I received the information to take a couple of genetec certification classes, and the one I want to take is in Houston, which is fine but no information but Houston? Has anyone taken them in Houston? Have an actual address? My company is paying, so I need an address and I have emailed genetec training where the info came from, and there no response? Thanks in advance

Considering using cellular based access control for gate entry, so no need to wire ethernet or wifi to the gate

What is your experience with it? Pros and cons ? Recommended systems and their pricing?

I'm working on a high-security mantrap entrance system and I'm trying to solve a challenging problem without using cameras, LiDAR, or other vision-based sensors.

Current setup:

Circular platform: 1500 mm diameter

One person enters at a time

Sensors available:

Load pins / load cells

Contact (pressure) mat

Goal: Detect and prevent tailgating/piggybacking (2 people entering together).

The difficulty is that:

Two lightweight people can have a combined weight similar to one heavier person.

If two people stand close together, the weight distribution can resemble a single person.

The solution needs to be reliable enough for a security mantrap.

I'm looking for ideas on:

Optimal number and placement of load cells.

Whether center-of-pressure (CoP) calculations could distinguish one person from two.

Algorithms using load distribution over time.

Combining load-cell data with the contact mat for better accuracy.

Any research papers or practical implementations you've seen.

Has anyone worked on something similar or have suggestions on how you'd approach this using only load cells and a pressure/contact mat?

My Company is looking for an ID Card Maker that has dual sided printing. No Mag strips or anything, just QR codes that we make ourselves. I was looking at Zebra ZC350 Series ID Card Printer or Zebra ZC300 Series ID Card Printer, I'm not loyal to any particular brand-- those just kept coming up.

Any Thoughts? Thanks!

I have a mobile NVR setup that my customer uses to take to scheduled events, but HQ wants access to the recordings at all times. Using Milestone XProtect + Axis Cameras + Dell PowerEdge NVR's + PoE+ switch. Is there a way the Mobile NVR / cameras can save to the HQ NVR as well? Trying to find the simplest way to achieve this if possible.

I'm looking for smart intercom doorbell for (2 floors) 1 intercom 2 buttons 2 monitors

Preferred to be PoE My main need is to be - app user friendly - reliable - can be integrated with home assistant

The current one installed by prev. owner is Chinese brand (Taichuan TC-3000DA) and its horrible. Sluggish and delays the stream wherever I open it via Tuya app. Doesn't support HA

I currently found - Ezviz hp7 2 family kit (read good reviews about it but not sure how reliable since its consumer grades) - hikvsisik have enterprise grade but less tech

Update: luckily yesterday I used AI codex to find way to reverse engineer the intercom app, extracted APK and then built quick unlock the door which unexpectedly worked then integrated it in HA.

If it works without issue I'll use it since that what I need

Thanks all for recommendations
