R-Series Products

The R Series is our economical and easy to use video surveillance line. These products are designed to be simple and effective and has all the basic features and ease of installation and use that the majority of users will need. These products are perfect for residential and small business installations of 32 cameras or less. Due to having some of the best prices on the web and designed to be easy to use, you can't go wrong with the R series. These products come with a 1 year warranty.

Q: Do the R series and H Series work together?
A: For the most part, yes! There are some exceptions that we would like you to consider though:

For standard non-specialty cameras such as typical domes, bullets, and turrets, the cross compatibility between brands will work fine. If you currently have a H Series NVR with a few H Series cameras connected and you want to add a few R Series cameras to your NVR or vice-versa. No problem! Setting up the cameras will be a little different when crossing brands but ultimately it will work.

However, if you are buying a system for the first time, it is recommended that you stay with the same brand for the sole purpose of the setup being more simple. If you stick with the same brand camera and NVR, setup is usually plug-n-play. While you can mix brands, you have to take some extra configuration steps to make them work together.

Also, if you are buying a specialty camera such as a PTZ, Fisheye, LPR camera, etc, we recommend that your camera brand be the same brand as your recorder for full feature use and compatibility issues.

H-Series Products

The H Series is our original and long running video surveillance line. These products are packed with features that would please a power user, yet simple enough to operate for a novice. These products are recommended for all installation types such as home, business, and enterprise. With a wide array of product types to choose, you are sure to find a product that meets your needs. These products come with a 3 year warranty.

Q: Do the R series and H Series work together?
A: For the most part, yes! There are some exceptions that we would like you to consider though:
