There are many DVR security systems made today that are very efficient at keeping homes and properties safe, and they are reasonably priced. Many of them can be found at websites that specialize in surveillance systems, and they can also be purchased from discount websites as well. It is a very good idea to learn about some of the best models on the market before deciding which one to buy and install in your home. Two of the most popular brands are the Defender SN500-4CH-002 4 Channel H.264 DVR Security System and the Defender SN502-4CH-002 Feature-Rich 4-Channel H.264 DVR Security System with Smartphone Access and 4 Indoor/Outdoor Hi-Res CCD Night Vision Cameras model. Both of these models are designed for use in a small to medium-sized home or business that is up to 3,000 square feet.
These surveillance systems were released in 2010, and they have other things in common as well. Both models have Smartphone access so that you can monitor your property when you are away from home. Also, they are both 4 Channel, and they have a H.264 compression level that saves space on the system’s hard drive. The main difference in the two systems is that even though they both have hard drives of 500 GB, the SN500 has a better compression algorithm, so it will record up to two years. The SN502 model will record for over one month. The SN500 model is built to have extra features, and it does have helpful extras, such as extra inputs that can be connected to an existing alarm. This provides added security because if the alarm is tripped, the SN500 will begin recording immediately, rather than waiting on motion to initiate its start.
The SN500 and the SN502 both have some of the latest options available in surveillance equipment, and installation is supposed to be easy. It is possible to view your video footage from your iPhone, Blackberry, or Android Smartphone, and in either a live or recorded version on your computer without fees from anywhere in the world. One major advantage to these systems is that the video quality is excellent because of the advanced compression level, H.264, which saves space. The advanced compression level also provides excellent video quality to make it easy to identify those who approach your door while you are gone. Both models have indoor/outdoor night vision cameras. This is a very important bonus in the SN502 model since the homeowner definitely wants clear night time photos. Night vision allows the homeowner to see areas with no light that are up to 15 feet away. The four cameras are also professional grade weather resistant high resolution color cameras.
The SN502 model has an email option that will notify you via the Internet or your Smartphone if there is any activity on your property. Some user reviews say that there are issues with this feature working properly, however. Also, the SN502 model is supposed to be extremely easy to install, but several current owners report that this is not the case, yet others found that the built-in interface. Most owners found the system very user-friendly and easy to install.
Both Defender models cost about the same at some websites, but the SN500 is a more expensive model that is higher priced at other websites. By far, most owners are happy with their systems, regardless of which one they purchased. Many people say that the night vision goes beyond the advertised footage, and that turning a light on nearby enables the cameras to see even farther. These two surveillance systems are highly rated and recommended by many owners for their features and reliability.
