Followed instructions as best as explained in manual

Can not connect to wifi. Killing batteries trying to figure it out. Downloaded app. I don't get no picture or response. Followed instructions as best as explained in manual. White screen. Not happy. Update # 2. Purchased this for my husband. He has had it about a week. I bought the kit with 4 batteries and case. Now sold out. 2 of the batteries will not stay charged. Still can't connect to the wifi. Phone or tablet.
