Camera resolution comparison – 1080P or 5MP
Security Camera Systems used for surveillance is moving toward megapixel resolution for HD video monitoring. You can find wide selection of megapixel resolution cameras, analog technology or digital technology or IP technology. The megapixel resolution format 1080P and 5 Megapixel.
Analog technology is evolving into digital technology which can offer high definition resolution. The most majority IP cameras can deliver megapixel resolution. 1080P resolution is most commonly used while IP technology is evolving and getting affordable. 5MP resolution has more than twice pixels than 1080P resolution. 1080P is equal to 2.1MP. 1080P has width (vertical pixels) of 1920, height (horizontal pixels) of 1080 and total pixels equals to 2073,600. 5MP has width (vertical pixels) of 2560, height (horizontal pixels) of 1920 and total pixels equals to 4915,200.
Resolution being one of important specifications for your IP cameras. Higher resolution means more image detail, but this doesn’t mean it can provide you excellent surveillance solution. Different from traditional digital camera, the IP cameras rely on network for video streaming, which means it will consume some network bandwidth. Typically, a 2 megapixel IP camera delivers 1080P resolution video at 30fps, and the network bandwidth required is around 4Mbps.
5MP IP network cameras are currently becoming more common resolution security cameras available in the consumer market and are a great choice for business applications where there is a need to capture the finest detail possible. IP megapixel cameras are recorded to a network video recorder, and allow for zooming capability in recorded video with minimal quality loss. Network based cameras have RJ45 connectors, and use CAT5e or CAT6 cabling. These cameras can be powered using a PoE network switch, a PoE capable NVR, or independent power adapters located next to the camera.
1080P analog cameras are still commonly used for residential sites. They are recorded on Didgital Video Recorder. They can be connected with Cat5, Cat6 or Coaxial cables. These cameras need separate power supply, which can located near DVR or near individual cameras.
