Ask Me Anything Surveillance

Sooo many camera options, Many get confused as to which system is best for ones needs.

My name is Sherrod Scott and for the last 10 years I've been installing, selling or designing residential and commercial grade surveillance systems. With numerous certifications and ongoing #Surveillance training, I'm here to help in any way I can.

Lets start with some of the basic terms and types of cameras.


#FixedLens Cameras:

This means than the mechanism which provides an image for the camera cannot be adjusted in anyway, think of binoculars, if you want to see something further you can adjust the lens to do so, not possible with this type of camera. From a custom prospective these types of cameras are available in various "Field Of View" angles from narrow to wide, otherwise you're likely to readily find these sorts of cameras in your local "big box" store usually with a wide "field of view".


#VarifocalCamera:

This term refers to camera (usually custom grade) in which the FOV (#FieldOfView) is adjustable during installation which could be handy in particular situations.


#PTZCamera:

A #PTZ camera or "Pan Tilt Zoom" is like binoculars and a camera had a baby together. often times these types of cameras can zoom in on objects miles away using optical zoom. Here in my city #Philadelphia the police have these mounted in various locations around the city, they are very hard to elude especially if they have been #automated.


#OpticalZoom:

A physical mechanism of lenses that can be a adjusted to visually bring distant objects closer much like #binoculars, this means of zooming has far more clarity that a digital zoom.


#DigitalZoom:

A software based means of visually bringing an object(s) closer using a fixed lens, case and point the pinching motion one uses to enlarge an image on ones cellphone camera is a digital zoom.




#Infrared:

This feature in a camera means that a camera is able to have vision in complete darkness, that there are small emitters that produce invisible light to the human eye allowing images to reveal themselves without the presence of visible light.


#Matrix Infrared:

Much like an infrared camera, matrix allows a camera lens to see in the dark. The difference is that the Matrix feature uses a light diffuser spread the light of the infrared emitters evenly resulting in a less saturated image. so instead of your images looking like ghosts in the dark, the image, though still black and white, looks more like a black and white photo taken in the daytime.


You can see the difference in the image below, both of these images are at night, but the one on the left is Matrix, far easier to see almost as it it was daytime.


Again, I could go on for days talking about this stuff, after all its taken me years to learn it. Any questions feel free to pick my brain.
