Ex our business monitoring system which has now been considerably upgraded
Old technology but a nice solid, flexible camera head for general purpose monitoring
Originally purchased in Australia, distributed by Fermax quite some time ago
FERMAX Turret Camera
Model: unknown - there are no markings except for the distributors name
All diecast metal case construction
3 part, ring style metal case which securely holds the head in the desired position - hex side bolt for locking
Suitable for ceiling or wall side mounting
IR illumination built in, operates automatically when the sensor detects low light levels
Manual FOCUS and ZOOM adjustments via recessed slot screws
Output is composite video on a BNC connector - female
DC power (12V DC) is applied to the pigtails (Red = positive Black = negative)
COSMETIC CONDITION:
Clean and no issues at all
Lens is clean, scratch free
TESTING:
Removed from service quite some time ago so I setup a quick test
DC 12V used for the power source.
100mA normal daylight operation
330mA low light level operation (IR Leds on)
A dull red glow can be seen from the IR leds, the fact this camera is in operation will be easily seen by an observer. This can be a good thing or not, depending if you wish to "scare off" unwanted guests.
Video is clean (not noisy) even in low light levels
Colour reproduction is adequate
In difficult light conditions such as a bright daylight source (the sun) and room shadows, the contrast is lacking which makes getting details in the dark areas difficult. See the photograph of the back verandah here, strong daylight and shadows on the verandah.
Also checked at night and the camera clearly shows facial features without any problems.
No sign of blooming due to extremely bright ambient light
PHOTOGRAPHS:
Not the greatest but I have attempted to show that yes, it works and how it behaves in different light conditions.
It is important to realise that I used my old analog CRT monitor for the video so the screen refresh gives the video a blurry appearance, in reality it is not blurry!
The orientation is also "weird" as I did not mess around with the head orientation - that chinese calender is on a wall about 6 metres away from the camera.
It's old technology for sure but perfectly adequate for a low cost, real time analog video monitoring system.
There are NO sound capabilities
