ADC-V723 alarm.com webcams won't stay connected to my Orbi RBR850
I have a series of ADC-V723 cameras. They'll connect to the Orbi network, but then drop off frequently and intermediately come back on - finally just staying off. I've turned off 20/40 MHz co-exi...
I found this thread by Googling. It's not the same unit, but it is the same behavior and it worked a year an a half on 3 different Xfinity wifi access points.. I recently replaced that access point with the cable modem CBK752 kit which has the CBR750 access point and the RBS750 satellite. Everything else connected fine including other IOT devices, but I can't get the outdoor cam to connect at all. I also have the indoor V522IR cam and it never skipped a beat (same wifi login/pwd).
I called support and alarm.com decided the wifi had failed in the cam so they sent me a new one. It won't connect either. When you load that little web page from the camera to give it the login, it shows a signal strength and mine's around 88 which is plenty. I moved the modem literally 2 feet to the left into the doorway of the front door and got it to 100 and still nothing but a red light. Finally I put the satellite right underneath the cam--and it quickly and easily connected!
I went inside to add the camera on the website and it wanted to install new firmware which I thought was great news based on DaveEdmonds' comment in January. I thought maybe there's a fix? It finished the upgrade and began working perfectly. I unplugged the satellite to put it back where it belongs, and it continued to stream via the router for a few minutes and then failed, going back to a solid red light and a worthless camera guarding my house. And that's where I am.
I don't remember mentioning firmware to get my working. The only way my camera for my security system would work was to hardwire an extra router I g=had laying around to facilitate an additional access point that I used to connect both my camera, the alram panel and my garage door.
There are apparently many devices that don't play well with a mesh style network unfortunately, even icluding many home soundbars and other interior devices.
Naw, what I meant was, you'd posted that they put in a request to the camera developer about this issue, and I was hopeful that maybe the firmware upgrade I got on a brand-new cam might be the fix.
Oh, got it. Yeah they never came back with anything or any information which sadly is typical of the alarm company we have.
Wait wait wait--I got it to connect. I saw a thread about a different security cam on Reddit in /r/orbi suggesting to set the 2.4Mhz Preamble Mode to Short:
Advanced tab > Advanced > Wireless Settings > Preamble Mode (top box for 2.4) set drop-down to Short Preamble.
I looked at the cam and it had a green light (!!). I was able to import it into alarm.com by searching on its MAC address and everything cranked right up. I don't know what that Preamble change means, but this was a complete surprise that it worked.
Interesting the RBS850 at least that I have has no such option for that setting. EDIT, I finally found it it was to the right of the setting. I may try that. Thanks.
