I am currently using this model, Bosch LTC 0620/11 Series DinionXF Day Night Camera, for my project. My power source is DC 24V. Can anyone recommend a 1/2" Digital CCD camera that has higher specifications and can outperform this camera from Bosch? Looking for horizontal resolution of more than 540 TVL. Minimum illumination is another major consideration. At night, this camera is operating in a near total darkness environment.
