Two Ways to Strengthen The Connection Set A Repeater Camera You ‘re allowed to set one of the Wi-Fi camera which is close to the NVR as a repeater to ensure the transmission stability between far away (or weak signal )cameras and the NVR. It is especially used in cross floor transmission or indoor-to-outdoor transmission. Use the Extension Antenna Connect the extension Wi-Fi antenna to the far away camera of which NVR receives weak signals to effectively avoid the transmission interruption between them due to the far distance or physical obstacles(as as walls). Stick it To Any Surface This 3m/9.8ft Wi-Fi extension antenna is built with magnetic base and equipped with a 3M adhesive tape. You can stick it to any metal surface or just attach it on walls or ceilings using the included 3M adhesive tape. Stable Point To Point Connection The IP cameras are stably connected to the NVR in their own network by factory setting. You don’t have to pair them again in installation. The the distinct connection separates them from other devices on your network and frees the system from interference. Work with Amazon Alexa Connect the system to an Alexa device to get live stream via your voice in a 100% hands-free way. Simply say “Alexa, show front door” to get instant view without smartphone.
