If you have to ask, then a camcorder. The other responses are good - pick one of them. I will add a little more for your informational question.
There are a couple of "desirable traits" dSLRs (and mirrorless) cameras designed for still image capture have when their video convenience feature is used. The ability to be selective about focal length and cause depth of field and the interchangeable lens system. The trade-off is record time and single file duration can cause the camera to overheat and shut down until cool enough to use. This specific known, published, issue has cause a couple of friends to have to purchase 2-3 of the same camera - on in use while the others are cooling down.
"Known, published" because you will find the warning in the manual of pretty much any single image capture device recording video. Purchase the same camera (at least the same manufacturer) to be sure the lens systems and color balance is close enough, the file types are the same and all other parts are pretty much interchangeable between cameras.
If you are convinced dSLR or mirrorless cams are the way to go, be sure to read through the rest of the "warnings" in their respective manuals so you can plan ahead all the various workarounds you may need. Once that may not be SO challenging is the single file duration limitation of 29 minutes and 59 seconds - assuming the camera has not already overheated and shutdown for cooling. Cooling time can take upwards of 15-20 minutes. That's why the additional cameras are needed.
Audio can also be a huge issue unless an external mic us properly used (the auto focus and aperture motors make internal noise that the internal mic records). An audio field recorder ( I use a Zoom H5) is very useful, but adds an extra step of synchronizing when editing.
The *best* path forward is to use a device designed to capture video. In this case, when combining the "desirable dSLR features" with a video capture device, the Canon XC10, CX15 or perhaps the EOS C100 or newer... or Blackmagic Design's Pocket Cinema Cam.
My perspective: I got a Sony NEX-EA50UH a few years ago (when they were new). In addition to the "desirable dSLR features" of APS-C imaging chip, interchangeable lens system (E-Mount) and even a hot shoe for camera mounted flash for still image capture, it has XLR audio inputs and a handy slide-out shoulder mount... but my requirements pushed me to replace it with a Sony PWX-Z150. Heck, even my HDR-AX2000 dances circles around the EA50UH under poor lighting conditions...
If you decide to get a less-than-$1,200 dSLR or mirrorless cam for "indie film making" understand you are doing the rough equivalent of using a Prius to haul dirt when a pick-up truck would do a much better job.
So plan your budget accordingly - be sure to include lighting, audio, steadying devices (tripods are common - camera cranes, short tripod, wheelchair, desk, shelf, stool, pretty much anything, but NOT handheld), cases (to protect your investment when you go on location), power supplies and additional batteries, cables, and lots more.
Just because you are doing this yourself and not through a studio does not make you an "indie filmmaker" any more than me buying a Formula race care makes me an "independent driver". If you have to ask this question, it is pretty obvious there is not much experience.
An "indie film maker" will still usually have makeup, wardrobe, casting, craft, set design, construction, grips, script, editing, storyboard, outline, project management, legal, payroll and lots of other items to work through... If you are doing none of these and doing everything yourself, chances are high you are a hobbyist or wannabe who has much to learn about being an "indie film maker". If you are doing low-end porn or in your teens and getting a few friends together and calling that "indie film maker", well, then, I'll give you those... On the other hand...
Someone with LOTS of experience can make a dSLR or camcorder produce awesome results because they know to work within the capabilities of the chosen device. Someone with no (or little) experience will expect the device to work a certain way - likely outside its design parameters - and produce poor quality video. The capture device is merely a tool that needs to be used correctly in order to produce good results... and needs to work with the other tools in the system (mics, lighting, editor & computer, etc.)...
