What to Consider When on a Budget
DVR home and small business surveillance systems can be very expensive, but they don’t have to be. There are a few aspects of any surveillance systems that, if carefully considered, can help the buyer get the most out of even the smallest of budgets.
Size of the Hard Drive
A DVR system can record onto a hard drive. The size of the hard drive determines the length of recording time the system is capable of. There are various hard drive sizes, with the most common being , 500 GB to 750 GB, and 1 TB to 2 TB, Naturally, the smaller the hard drive, the less expensive the unit. A unit that offers up to 500 GB is normally more than sufficient for most home and small business surveillance needs, making it unnecessary to spend more money purchasing a larger hard drive.
Number of Channels
The number of channels a surveillance system offers determines the number of different cameras that can be used with the system. Buyers generally have the option of 4, 8, 16, or 32 channels. For most residential home and small business surveillance needs, a four or eight channel system is sufficient. This means the user has up to a maximum of eight cameras to use.
The term resolution refers to the number of the smallest picture elements or pixels that make up a video image. The more picture elements, the better the detail of the picture. Resolution for analog cameras is typically measured in Television Lines or TVL where resolution in digital cameras is typically measured in pixels and communicated by either the number of pixels both horizontally and vertical (such as 640 x 480) or as a total number of pixels in the image (such as 1.4 megapixels).
In a camera system, resolution is typically the balancing factor. Depending on the purpose of your system, you may need a large resolution in order to recognize faces or licenses plates. Under other circumstances, you don’t need a high resolution at all because your field of view is so large you only want a general idea of what is happening. Typically adjustments to a camera system are made to get the most resolution with the lowest storage and bandwidth requirements.
Many DVR home and small business surveillance systems require an experienced professional to install. This can end up being very expensive. For those who want to buy a surveillance system on a budget, a self- installed system can be a good option. These systems are designed to be simple to install with minimal knowledge required. These products tend to come with step-by-step installation instructions.
