Many times consumers believe the higher the megapixel, the better the image quality which is not necessarily the case when choosing a camera package. One must take into consideration their specific needs for their surveillance system. Storage capacity, indoor/outdoor cameras, how much coverage is needed, lighting conditions, overview or high detail will all determine the type of image quality needed to fulfill the necessary requirements.
Some locations will see various degrees of light. Wide dynamic range (WDR) cameras can capture the appropriate balance of low light and high intensity lighting situations. In cases where cameras need to monitor nighttime scenarios, IR cameras provide the clarity needed to monitor little to no light environments.
When monitoring a wider field of view, some PTZ cameras have the capability to zoom in over a mile away. Higher megapixel cameras aren’t necessarily the best option in such a setting. As see in the video to the right, this Vivotek 2MP SD camera can zoom up to 800ft. away in complete clarity.
CCTV vs. IP Cameras
IP-based Video surveillance has numerous benefits over analog, such as increased scalability, flexibility, and facilitates intelligent surveillance such as facial recognition, object recognition, license plate recognition, automated alert, and automated email generation. In analog systems, the DVR, once installed, becomes unable to adapt and assimilate advancements in hardware and software technologies. IP camera video technology allows for a larger, clearer picture than analog CCTV cameras, due to the fact that IP cameras have higher megapixel abilities. The IP camera sees more of the coverage area, with a clearer image and more details. In cases of suspicious activity, this allows for further enhancing and zooming to search for evidence when necessary.
