The real surveillance ones are the ones safcom setup. they look like CCTVs. They can zoom - change direction like 360 degrees. These are the ones that are useful 'kutafuta watu'. The flash in the speed cameras is for usiku - number plate lazima ikuwe legible. The big issue i have with the 'speed' cameras (over and above that they have been placed in places where the road naturally limits speed) is that we don't have a way to really send the results of the system to the unsub. where they have been implemented well - the results are sent to your mail box and then you go pay ama contest in court. hapa sasa kabla upatikane ni lini?
@Masukuma, a cctv camera is not called a speed camera because it is meant to record fast moving objects in its field of view, NO!!
To start with any cctv camera is a surveillance camera and it does not matter where it is installed.
There are two types of surveillance cameras namely, the fixed and the PTZ (Pan, Tilt and Zoom).
The fixed camera can further be categorised into two types…fixed lense and varifocal lense. The fixed lense camera only records images from a a specific field of view which does not change…the focal length of the lense is fixed. The fixed zoom camera on the other hand has lense whose focal length can be changed either manually (manual varifocal lense) or automatic (Motorised zoom lense)
The PTZ camera can record images from a 360° horizontal field of view (Panning) and about 300° vertical field of view (Tilting) and at whichever angle of view it can also Zoom. The PTZs do have varying Panning and Tilting speeds. However in cctv surveillance design the most important is the panning speed. The lower category PTZs usually have low panning speeds of between 0° to 100° per second while the higher category PTZ can give anywhere between 200° and 300° per second panning speed. These high panning speed cameras are often refered to as Speed Cameras.
Fair enough but I will confess something to you…at least 80% of cctv installations in Kenya were installed without a design and they offer very poor quality recorded images…
...besides, the presence of a safe alone does not signify that there is money inside...
