If the sensors on the hub are registering "disarmed" or "offline" it could mean they are actually in sleep mode. They are still active and armed however the app may list them as offline as they are in sleep mode until it is triggered.
The sensors may go into sleep mode if left idle for an extended period of time and no movement has been detected while in Away mode. To resolve this issue, ensure the sensors are armed in away mode and create movement at the sensor, the status of the sensor in the app will return to "armed" status.
If the senors or hub are still registering as offline, other issues may need to be considered, such as distance and location of the device.
The Amcrest alarm hub has a communication distance of up to 328ft (open field) however if you notice the system is going offline regularly or becomes unresponsive your network and the location of the device may play a huge role in its ability to function properly. For more information on location and how it affects a Wi-Fi device, please refer to the information provided below.
Location: How far is the hub is from the wireless router.
- Larger distances can be affected more by interference and be susceptible to connection issues. This can cause the hub to go offline which will also affect the sensors.
- Actual distances can vary drastically by the type of router. If connection issues arise, then a Wi-Fi extender should be considered.
Range Limiting Factors
|Reflection: The signal reflects.||
Scattering: The signal scatters back into multiple new signals.
|Refraction: The signal bends as it travels through an object (e.g. glass window).||Diffraction: The signal changes direction as it passes around an object.||Attenuation: The signal strength weakens as it passes through an object.|
Wi-Fi signal strength decreases as it passes through different types of material. Try to position your wireless camera and receiver where the signal does not pass through metal or concrete blocks, which can significantly reduce signal strength (as shown in the information provided below).
Plastic & Wood: 10 - 30%
Brick: 30 - 50%
Concrete Cinder Blocks: 50 - 70%
Metal & Metal Cladding: 70 - 90%
Note: Signals that must pass through wet or moist materials (e.g. shrubs and trees) may be significantly reduced.
