The following is written in order to help you to understand what different types of CCTV Cameras are being used in Security Camera Installations today and how we at Ideal CCTV determine, which one to use.
These are the main types of CCTV Cameras:
IR Vandal Dome Camera
Outdoor IR Dome Type
Housed Body Camera
Outdoor Box Camera
Camera in CCTV Housing
Outdoor Housed IR Camera
Outdoor Housing with IR Spot-Light
HD IP CCTV Camera Type
These Cameras can be/ incorporate:
- DSS Night-Vision
- Infra Red Night-Vision
- Vandal Resistant
Housed Cameras Vs Dome Cameras
Housed cameras (CCTV Cameras in Wheather-Proof Housings) are used, when the camera needs to have a very far zoom, or when a very high deterrent effect is desired. Static (not rotating) Dome Cameras look neater and are not as obvious. Professional Dome Cameras have the same picture quality and specification as Housing Surveillance Cameras, but aregenerally easier to install and slightly cheaper to purchase. Most professional Dome Cameras incorporate a three-axis-gimble, which allows to camera to be mounted in any position and still be adjustable to view any desired angle.
Keeping cost in mind, we recomment static dome cctv cameras in most locations -- unless a very high deterrent effect is desired.
PTZ Speed Domes
These are also dome shaped CCTV Cameras, but include pan, tilt and zoom capability. These cameras can be set up to follow pre-programmed routes and presets. Most applications include a joystick - keyboard, operated by surveillance personal. Ideal CCTV recommend Speed Domes for vast area projects like car parks.
Generally for reliable security we recommend to stick to static (non rotating) CCTV Cameras, as very often during important incidents the Speed Dome monitored another area and no evidence was captured.
All security risk areas like gates, ground floor window rows, doors and fire exits should have their own static camera, zoomed in on the highest risk area.
IR Night-Vision CCTV Cameras vs Sens Up DSS Night Vision
Everybody speaks and writes about Infra Red Night Vision - but few people are aware that the majority of IR illuminated cctv footage is not usable for identification of suspects. Common problems are:
- IR too weak on distance but..
- ..too strong for close up suspects, which causes..
- over-illumination of faces and loss of facial marks. Often the face is shown as a white blurr
- images and video are recorded in Black and White only.
We at Ideal CCTV have changed our approach and turned to DSS Night-Vision. CCTV Cameras that incorporate this advanced light sensitivity require an absolute minimum of light. In some instances moon light or even star light can be sufficient to give a clear and crisp colour picture at night time. Ideal is the presence of a street lamp within fifty to eighty yards or the installation of one low-light source might be recommendable.
DSS night vision cameras deliver clear colour recordings in situations where the human eye hardly sees a thing.
We do not recommend DSS CCTV Cameras in applications where fast moving objects like cars etc. are the main aim of surveillance.
