Here is the 4 camera grid view on the security camera system DVR. The HD video that I created and the screenshots that you see below were all captured at 4K resolution (12 megapixel) from the DVR’s HDMI video output. The image is simply stretched to meet the resolution of the connected monitor. This means that 1080p and 5mp cameras can be displayed at 4K resolution on the monitor that is connected to the DVR. The DVR supports 4k resolution video output via its HDMI output. The iDVR-PRO DVR that we used is able to record at 1080p and 5mp resolution. The BPRO-OL952 was set to 1080p (2mp resolution) and the 5MP-BL52 was set to 5mp resolution. **Please note that CCTV Camera Pros is now recommending our best selling Viewtron 4K security camera DVRs. The 5MP-BL52 supports 5 megapixel and 4 megapixel resolutions in AHD, HD-TVI, and HD-CVI video modes.īoth cameras were set to AHD (analog high definition) video mode and hard wired to an iDVR-PRO hybrid CCTV / HD security camera DVR using RG59 Siamese coax cable. The BPRO-OL952 supports 1080p / 2 megapixel resolution in AHD, HD-TVI, and HD-CVI video modes. The testing results are expected to be the same if I would have used IP cameras instead of HD CCTV cameras. Both are HD-over-Coax BNC cameras which means that they support multiple video formats (AHD, HD-TVI, HD-CVI, and analog CCTV / CVBS). Both of the bullet security cameras have a 3.6mm fixed lens, however, the 5mp version gives a slightly wider angle of view because it has a larger image sensor. The one on the left is a BPRO-OL952 1080p camera and on the right is this 5mp-BL52 5 megapixel security camera (which is basically a 5mp version of the original BPRO-OL952). These are the two bullet-style surveillance cameras that I used for the comparison test. Typically, a 2 megapixel IP camera delivers 1080P resolution video at 30fps, and the network bandwidth required is around 4Mbps.I recently performed the following test to compare CCTV video surveillance recorded using a 1080p vs 5mp security camera. Different from traditional digital camera, the IP cameras rely on network for video streaming, which means it will consume the some network bandwidth. Higher resolution means more image detail, but this doesn't mean it can provide you excellent surveillance solution. Resolution is one of important specifications for your IP cameras. Note: 6 megapixel and 8 megapixel IP cameras are still under development Comparison between 960P, 2.3MP, 3MP resolution Comparison between 1.3MP, 2MP, 3MP and 5MP Name ![]() ![]() The most majority IP cameras can deliver megapixel resolution. Since the rapid development, analog technology is evolving into digital technology which can offer high definition resolution. ![]() 570K pixelsĪnalog technology has been dominated the video broadcasting and surveillance fields for many years. PAL: 700 TVL = 976(Horizontal) x 582(Vertical) = Approx. ![]() NTSC: 700 TVL = 976(Horizontal) x 494(Vertical) = Approx. It indicates how many effective pixels the camera can deliver. In conventional analog technology, Television line (TVL) is the the main specification for analog cameras. Herein we are pleased to provide some basic information about the different resolution format. Currently, the megapixel resolution format including 1.3 megapixel, 2 megapixel, and 3 megapixel, as well as 5 megapixel, 6 megapixel. Today, you can find wide selection of megapixel resolution cameras which adopting analog technology or digital IP technology. Video surveillance is moving toward megapixel resolution for HD video monitoring.
