Emax's Cinehawk Mini is a great little quadcopter, both indoors and outdoors. The prop guards make it ideal for flying around people, and in tight spaces where you might bump up against things. It can handle dives with ease, since it's very responsive, and lightweight, even though it's a cinewhoop. This sub-250 quad comes with either no vtx or a DJI O3 Air Unit installed. You can install your own camera and vtx system if you don't want to use DJI O3 -- the box contains camera mounting options that you can use.
