They could all have been made to support one frequency and it would simplify the sensor manufacturing. It would also simplify the control panel manufacturing and not require extra modules
The lower frequency rf is not used for more data heavy transmission like TS1, Go!Bridge, and Image Sensor and 345 mhz would not be used as a data transfer rf. 900 mhz is necessary for these GC2 devices.
Does the GC3 have a 345MHz and 900 MHz transceiver built in, or do we still need to buy a 900MHz module
The GC3 does not currently have a compatible image sensor, though we expect one soon and when one is released it will likely require a transceiver of some sort for communication. Currently there is no additional 900 mhz radio for the GC3.
or if you are talking about a totally different PIR sensor that is in the works and the current one will never work.
It will be a different model. The GC2 model will not be compatible.
Do those items work with the GC3? Do those sensors pair with the thermostat, the control panel or both. It sounds like you pair them with just the control panel, and alarm.com can use them in whatever way you want to automate things (obviously to control the temperature on your thermostats, but I’m sure other things are possible).
The remote temp sensors are not officially compatible with the GC3, but as above we have had reports that they will function through Alarm.com but the panel’s UI cannot properly display accurate status.
Keep in mind that unlike most other compatible Z-wave devices, the RTS requires to be learned in through Network wide inclusion, meaning the Panel and the RTS must be in their final locations before learning in. The more of them you use the more important it will be to use repeating nodes like light switches and appliance modules.
With my previous system, I had a rule that said if my alarm was unarmed, it would arm-stay at 8PM. I would try to have my alarm armed-stay as much as possible throughout the day, but just in case I forgot at night, it would get armed. I never scheduled an automatic disarm time. Would this require the additional scheduling option?
Yes, automatically arming would require arming schedules. I typically prefer arming reminders over automatic arming - greatly reduces false alarm potential. However, schedules can be very handy.
Arming reminders can be set up easily and do not require the schedules add on.
Is the ADC firmware updated as often as the retail Skybell? When I look at the retail Skybell, it says it is compatible with ADC and other systems. It does not mention it is incompatible and you should buy the ADC version, but I know you have stated in lots of areas that they are different firmware
We really do not have enough of a time frame for reference to make a comment to the frequency of updates. However, you can update firmware on video devices, including the Skybell HD, by logging into your Alarm.com account and navigating to the device settings for that camera. The most recent firmware version will be displayed as well as your current version with the option to update.
No, you cannot use a retail Skybell HD with Alarm.com service. Alarm.com is a partner listed on Skybell’s website, but it does not use the same model device. Skybell does not directly sell Alarm.com model devices. The reverse is also true. An Alarm.com branded model will not properly function with Skybell’s app.
