You can improve the picture quality of your Blink cameras by adjusting the video settings in your app (Note: this will reduce battery life) and ensuring it's within range of your Wi-Fi router. The Camera to Wi-Fi signal strength plays an important part in how your video quality is rendered, since that data is downloaded directly from the Blink servers to the camera. Camera to Sync Module signal strength has no effect on video quality; however, it needs to be strong enough to keep cameras online and responsive.
In addition to checking your video settings and signal strengths, camera positioning is also important since environmental conditions such as lighting and glare can affect your video quality.
When the signal strength between your camera and router isn't adequate, you may experience the following:
Your Wi-Fi router may also have settings to optimize video streaming.

Additionally, some routers have implemented WMM (Wi-Fi Multimedia) as a standard, designed to improve video over Wi-Fi networks.
