Can I use the MPcam F Series MPF-7018 camera outside?

Yes you can but only if the weather is permitting.  Our MPCam F Series MPF-7018 is designed primarily for indoor use, but can be placed outdoors in desirable weather only, not wet or too hot.  Rain, snow or any other forms of moisture will cause issues with the camera as will direct heat.  If you must place the camera outdoors place it in a shaded area so as to deflect direct sunlight and to prevent moisture from getting onto camera and do not leave the device out overnight as condensation will harm it also.  It is strongly recommended that you do not place the unit outdoors, instead we recommend you place the device in an indoors location were it can view the targeted area outdoors.
