Everything you need is included in this package (except the screwdriver)! The cameras are easy to setup and can be installed on the wall or the ceiling with all the adjustment options you will need for your location. You're provided with ample cabling to distribute the cameras throughout your home/business. This model includes 2 cameras with the system, but you can easily add an additional 2 cameras if necessary.
The DVR setup is also very easy, and you'll be guided through the system via the onscreen setup process with no need to read through the manuals. The included HDD is an ample 1 TB in size, which will give you lots of recording time, whether you choose continuous record or motion detection based recording. Even if you choose the default compression, the image quality is very good. You have a number of playback and monitoring options to suit your needs. They've really done a great job of providing a turnkey system that does what you want it to do right out of the box, and yet if you want to tinker, you have a vast array of configuration options available.
You really can't go wrong with this system, especially for the price!
