There are various factors that determine the camera that is right for applications and at a location. One size does not fit all in safety cameras, and the design takes into the opinion, location, and effect lighting requirements, or views demanded. Put a color camera as the camera struggles to watch, and you will find Grainey a video and noisey. Video security cameras are either standard color cameras, Day\/Night cameras, or in infrared cameras. They come optically zoom in on places and in fixed, meaning they see Pan Tilt Zoom cameras that permit the operator to maneuver the camera in a 360 area, or one location.
A standard retail environment may have both outdoor and indoor cameras, fixed and PTZ, with interior and exterior doors entry's and exits covered. Analog cameras are measure in Television Lines meaning the lines which constitute the camera video on the screen's number. Cameras quantified 380-420 TVL because the resolution that was typical. 540 TVL is a resolution for CCTV Cameras today. This barrier is being broken by IP Megapixel cameras. A 3.1 megapixel camera includes over 2000 lines. As IP Megapixels are Mega Bucks, today the cost is the deciding factor. Whether you have a big spending budget, spring for a Megapixel Cameras, for the cameras focus on 540TVL and over resolution CCTV cameras.
An essential aspect in cameras is the lighting during the night. Are there parking lights? Is it pitch dark? If there are limited lighting, a Day\/Night camera is your choice. Its color during good lighting, and switches to B\/W for low light views. The key technical spec on light is the LUX rating. The lower the better. Standard color indoor dome camera will have a LUX of 0.1 and a Day\/Night will have a.001 or better. Being able to see both night and day, IR Cameras have IR LED's which Are beyond what that the human eye can see, but that the camera picks up that the IR light flashes that the continuous Flashlight enabling you to see in total darkness.
Got to have one! A fixed camera is like having an one eyed guard stand watch. A PTZ robotic camera is like having that the same guard, but he can maneuver around and includes a set of binoculars to get close-up shots. There's a difference at a $50 camera and a good quality $250 camera at a lot of cases. IP megapixel cameras at $800 or even so, will be a distant memory hopefully soon because volumes increase. Whether its an affordable or professional buy, choose that the right camera for your application.
