Why choose 4K IP cameras over 1080P?
Let's begin by first comparing common resolutions in megapixels, and image size in pixels:
- 4K = 8.3 megapixels, 3840x2160 pixels
- 1080p = 2 megapixels, 1920x1080 pixels
- 720p= 1 megapixel, 1280x720 pixels
- D1 = 0.4 megapixel, 704x480 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.
Ultra HD 4K vs 1080P
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.
4K NVRs
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.
4K Security Cameras
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.
