When purchasing a high resolution security camera system it is important to have realistic expectations of what to expect. While everyone wants the latest cameras with the highest resolution sensor for the best clarity, they usually forget to take in to account the data storage implications that come with high definition cameras. In this video guide, we demonstrate and discuss what to expect from 8MP and higher resolution security cameras when reviewing recorded footage.
CCTV Camera World now carries the latest 4K IP cameras that provide Ultra HD resolution of 3840x2160 pixels. 4K resolutions are available in cameras using 8MP and 12MP CMOS image sensors and require specific network video recorders like these 4K NVR recorders with high bit rate encoding capabilities. It is important to note that roughly 10 to 15 Mbps of bandwidth is required for a single 4K IP camera recording at 7fps at mid to low compression to yield acceptable video quality without significant compression artifacts. New for 2016 is the introduction of 4K security cameras with video streaming at 15fps which requires about 15 to 20 Mbps of encoding bandwidth. Hopefully in 2017 we will see product rollout with real time recording capabilities at 4K. All the 4K cameras we carry have robust Smart Detection capabilities as well which we will explore in the coming weeks. Below you will find our 4K camera reviews and more information about why choose 4K surveillance cameras.
Technology is rapidly advancing on a daily basis in terms of quality, reliability and affordability. In the security camera world, cameras are becoming more compact and efficient in their design, while offering better features and higher resolution. One such example is the brand new product we are reviewing here, the 4K Ultra High Definition IP Bullet Camera. This camera offers incredible resolution for a security camera, along with IR night vision capabilities, Continue reading
Surveillance technology has come a long way. Demand for higher resolution cameras and related advancements in CMOS sensor technology have led to some phenomenal security camera products in the industry today. This Dahua 4K Fisheye Dome IP Camera IPC-EBW81200 has an astounding 12MP (megapixels) resolution CMOS image sensor. It produces 4K resolution video that is 4000x3000 pixels Continue reading
Let's begin by first comparing common resolutions in megapixels, and image size in pixels:
Mainstream CCTV cameras have been D1 resolution (704x480 pixels) for the longest time until 2014, with megapixel sensors being price prohibitive for the home or small business. As image sensor technology improves, it has gotten cheaper and allowed 1080P cameras to become so affordable that they are on pace to replace analog resolution security cameras as the base resolution for a starter system. 1080P HD security cameras are more than adequate for indoor use where the subjects are no more than 40ft away from the camera, and even for outdoor use in most cases. However, if you wish be able to zoom in and identify facial detail on recorded video at distances of 30ft or greater, that is only possible with 3mp ip cameras, or greater resolution cameras. If you're looking for the most detail at a wide angle, then 4K IP cameras are the recommended equipment.
When you compare pixel count, 4K security cameras are 4x higher in detail than 1080P.
This higher level of detail in the picture afforded by a higher pixel count makes 4K security systems ideal for high-traffic areas where detail is crucial in indentifying the difference in someone dancing and fighting. Too often, lower resolution security cameras leave ambiguity lingering as to what really occurred in a surveillance video clip. 4K cameras clear up this ever so present uncertainty in video footage. Athletic fields, Schools, universities, big box retail, train/bus stations and government facilities are just a few of the industries that could benefit from these 4K security cameras.
Depending on the size of the 4K security camera system you need, we offer network video recorders for 4K cameras in densities of 8, 16, 32, 64, and 128 channels. The 64 and 128 channel NVRs are available with hard drive Hot Swap ability which comes in handy in professional and business security projects where long term video storage is needed. Drive Hot Swap lets you replace video storage without ever having downtime.
Ultra HD surveillance cameras are offered in three designs at this time. With all being IP66 or higher rated, they are all weather proof and can be used outdoor or indoors. There is a bullet and dome camera with 8MP CMOS sensor, and 66ft of infrared night vision. We also have a 360 degree fisheye dome camera that has a 12MP CMOS sensor, 32 ft night vision, and is IK10 vandal resistant. As is the case for all of our cameras, they contain advanced chip sets that allow for bandwidth control, image optimization with features such as DWDR, BLC, HLC, and digital noise reduction (DNR), allow of which allow you to optimize video in order to achieve your desired needs.
