Wifi jamming by thieves

Does the IQ Ethernet card replaces the wifi card inside the IQ4 panel?

No, there is an empty slot between the PowerG and legacy RF cards

Are there any instruction on the Ethernet card install or anything related to it?

Panel should be updated to the latest firmware before installing the card. When installing, the panel should be completely powered down. Steps 1-3 here cover how to do so safely.

If using the ethernet card, there are some things to be aware of.

  1. Wi-Fi and Ethernet cannot be used at the same time. To use Wi-Fi, the ethernet cable must be removed from the card. Anytime you plug in the ethernet cable, Wi-Fi is disabled and it needs to be re-enable once you remove the Ethernet cable. The panel will not revert to Wi-Fi automatically if the cable is removed. The card does not need to be removed to do this.

  2. Live View at the panel with Alarm.com cameras is not supported with this integration. While I have been able to get some cameras, like the V515, to work, doorbell cameras in particular do not fully work. Your mileage may vary.

  3. Firmware updates must be done over Wi-Fi.

Also, for the Power G wireless siren/strobe, are there any instruction on how to enroll into IQ4?

We do not offer that device so I dont have specific steps but you should be able to do it through Auto-Learn mode like any other PowerG device. Ill follow up if I find anything specific.
