Important Notes:-For our endoscope camera, it is featured with fixed focus, instead of zoom focus. Therefore,in order to get the best image quality, the best observation distance is about 4CM-6CM, if too far or too close, it may both affect the image quality.-Please take off the protective film on the WIFI box. It's normal that the camera will turn hot especially when the LED is in the brightest condition, and it will not effect the usage or life-span of the Endoscope.-It may have moisture in camera and affect the image when you put the endoscope in a humid environment, please turn on the camera LED for 5 minutes before use, the heat will clear up moisture.-Needs to be connected with your phone via wifi in your phone network settings, instead of the app.Specifications:Support System: IOS/Android/Windows/MacImaging Sensor: 2.0 Megapixel CMOSCapture Resolution: 1600*1200 1280*1024 1280*720 640*480Viewing Angle: 60°Camera head OD: 8mmEffective Focal Distance: 4CM-6CM(The best viewing distance)WIFI Transmission Distance:Within 5-30m(without any obstacles)Camera Light Source: 6 adjustable LEDsWaterproof Level: IP67Operating Temperature: 32℉ to 158℉(0°to 70°)Cable length: 3.8M/5.6M/10MFrame Rate: 30FPSBattery Capacity: 750mAh(Last for 110 minutes)Size: approx. 66 x 34 x 16mm/2.57 x 1.25 x 0.54''Package Contents:-1* Micro USB cable(charger line)-1* Phone stick Silicone Case-1* Wifi Transmitter-2* Accessories(mirror, hook,magnet)-1* USB adapter line(to connect PC)-1* User manual-1* The line with HD endoscope
