Key considerations in selecting monitors
When looking for a new CCTV monitor, buyers want to consider more than just size. This buyer’s guide highlights some key facts to keep in mind when choosing and comparing different types of monitor units.
Whenever possible, it is better to choose an LED instead of an LCD monitor. An LED panel uses less energy and is therefore cheaper to run than a similarly sized LCD panel. LED monitors use up to 46% less energy over the life of the unit.
One of the main reasons for the failure of an electrical device is the accumulation of heat in the chassis. To combat this, monitor buyers should select, when possible, a monitor with an external power supply. This will greatly reduce the heat generated within the unit and extend its longevity. LED monitors emit less heat than LCD monitors because they use less energy.
A CCTV monitor is a display device that is generally connected to power from a surveillance video recording device. Systems can be “future-proof” to some degree by using a monitor with multiple inputs. Most DVR and NVR devices have a VGA connection, while some have HDMI or DVI connections. Fewer and fewer digital devices use an analog BNC-style connector as the display output, and this trend is unlikely to reverse. Buyers should select a monitor that provides the most flexibility in the future.Connectivity
When buying a monitor, it is important to select the panel that suits the maximum resolution of the device, or more commonly, the connecting cable. Most standard HDMI and DVI cables will support 1920 x 1080 resolution.
New technologies such as OLED and 4K TVs have been launched to the consumer market, and this could have a significant impact on the industrial market. In any case, if these new technologies gain popularity, advances in cameras, DVRs and NVRs, technology and cabling are likely to continue.
