Dairy farms have unique security needs. Farmers have many assets, from machinery and buildings to livestock and feed, to protect, yet they often live in rural areas with limited internet options. If you own a dairy farm where DSL is the fastest internet connection available, black and white, low resolution security cameras will protect your barns without using up all of your bandwidth.
DSL Has Limited Speeds
Although DSL, which uses satellites instead of fiber optic cables, is technically high speed, it isn't nearly as fast as cable internet is. According to About Tech, cable supports internet speeds of up to 30 Mbps, but DSL is limited to about 10 Mbps in most cases.
While DSL is much faster than an old 56k modem, it may not fast enough for today's homes that have many devices online. If your family uses several computers, has a smart television and streams music on an MP3 player, a DSL connection might not be able to handle many other devices.
Black and White Cameras Use Little Bandwidth
While any IP security camera will use some of your bandwidth to transmit its video feed, black and white models will use less than color ones, because black and white IP security cameras have less data to transmit. In more urban settings, homeowners can install color cameras and just upgrade their broadband speed. Because DSL has a maximum speed of just 10 Mbps, though, installing black and white IP security cameras often work better in a rural setting like a dairy farm.
Forgoing a color video feed won't significantly impact the overall effectiveness of your security system. The biggest threat of vandalism and theft is during the night, when you and your farmhands aren't around your barns. In the dark of the night, color cameras aren't able to provide a color feed, anyways. Everything will look monochromatic at night regardless of whether you have black and white or color IP security cameras.
Low-Resolution Cameras Also Use Little Bandwidth
You can further reduce the bandwidth that IP security cameras will use by installing low-resolution models. Specifically, cameras with between 400 and 500 television lines (TVLs) will provide adequate detail.
TVLs, Lorex explains, are the units used to measure security camera resolutions. To determine how many TVLs a camera has, a picture of the camera's feed is taken. The picture is cropped so that the horizontal length matches the vertical height of the picture, and then the number of vertical lines within the picture are counted. The result is that model's TVLs.
Most home IP security cameras have between 350 and 400 TVLs, although some high-resolution cameras offer up to 800 TVLs. In and around a barn, you may need a higher resolution than a homeowner needs, because barns tend to be larger than homes.
Unless you're monitoring activity across vast fields, though, you don't need 800 TVLs. Lorex has a picture of a 480 TVL feed that provides a clear picture of a parking lot, residential street and building on the other side of the street. A camera like this is low-res but has enough detail to provide a quality image of most dairy barns.
If you're going to install IP security cameras around your farm, you don't need to invest in the fanciest high-resolution, color cameras. In many cases, low-resolution, black and white IP security cameras will provide adequate detail -- and they won't use up much bandwidth. For a dairy farm in a rural area that only has DSL, this latter consideration is especially significant. After all, an IP security camera's video feed is only useful if you have the bandwidth to support the camera.
