So lets go over a few things that we have mentioned.
The Bullet Cam has a price tag of around $250 for 600 tvl and you still have to get a monitor. The LCD screens are O K but the digitals are a bit costly. "You pays your money and you takes your choice"
The GPS setups are nice and very costly, but you can get all of that for free on your smart phone. There are apps out there that will do it all for free basically. Any of you guys use Waze? I have that on my Android and it is great.
Cam wants something that will do 100'-300'. That is a lot of distance Any of you guys that looked at my video of Coffee and Octane can see this is just a $36 camera. Put it on a tablet or digital device and you can see just as though you are there. Any small monitor(digital or LCD) will give you reduced vision so to speak, just like a small IPhone or Android will.
The bullet cameras(security cameras) won't work because where are you going to put those long cameras???
The board cameras will give you a great picture if you have a big enough screen or digital monitor. If you don'twant to play with the electronics(5volts) of the Runcam or Mobius then stick to the 12 volt setups. I have mine setup so that I can watch them on the monitor, tape, and they can pan and tilt while I watch them.
If you like the idea of the Runcam of Mobius then you have to have a USB outlet or a step down voltage regulator. The Runcam has the ability to be both on the monitor and tape at the same time. Cost is inconsequential in that these parts mentioned above cost about $2-4 on Ebay. The pan and tilt material cost under $25 You just have to put up with the tiny wires they use.
You should be able to go with just about any setup for under $200 and most of that is eaten up by your monitor. These tiny cameras that the RC community are using are cheap because the competition has driven the prices down. You need to stick with the lenses that give the best view(90-120 degrees FOV) or are large in size 3.6mm like on my board camera. Most of the sellers will put different lenses on if you request it. the FPV(first person view) guys like the wide FOV for their flying. We aren't interested in the panoramic view, just what is behind us or coming up on us. Get at least a 7-9" monitor.
One last point that was missed by the bullet9security) cameras. They don't have the ability to reverse the image for rear view. All of the board cameras are all programmable for just that(and much more). Other wise you are looking at an image that is the same as if you turned your head around and looked. The curb will be on your left , but in a mirror, it is on the right.
Any one needing help in looking for the RC info just PM me and I can supply some of the better sites and equipment.
