For seeing as much of the immediate area as possible such as above a doorway/low down/garage soffits (edges can appear slightly warped/distorted) - clearly "zoomed out"

A smaller lens will give you a wider angle but will be “zoomed out more”, while a bigger lens will narrow the angle down and “zoom in more”. See below to give you some idea on angles of Megapixel HD Cameras: Lens in mm With a working temperature of -30 °C to +60 °C, IP67 weather-proof housing, a panoramic & rotation movement of 360° and a tilt of 75°, this is perfect for outdoor use, although it can be for indoor use too. Key Features I've personally only ever used 4 or 8 (there's no specific reason for that decision). 8 MP are a good choice if you're covering a larger area or are using the ultra wide 2.8mm lens; if not 4 MP are fine. Look at the data sheets and they give you some DORI (Detect, Observe, Recognise, Identify) distances that may be of use. If the cameras are connected to a Hikvision NVR you'll need to be mindful of how much bandwidth you have available on that NVR. These Hikvision cameras features PoE for easy connection and configuration, via Hikvision NVRs and also 120dB Wide Dynamic range as well as 3D Noise reduction.
