Video System: PAL Colour fully compatible with
Australian TV System.
Image Device: 752 (H) x 582 (V) 437 664 Pixel
LOW BLEMISH CCTV CCD
Sensor 1/3" Sony - Due to the highly
sensitive nature of this image sensor it may have more blemishes than ordinary
sensors, these imperfections may continue to appear after manufacture until the
photodiodes stabilise as the sensor ages, additional information
here.
for:
Super HAD MicroLens information @ "SONY"
Lens: Variable Focal Length 4 mm ~
9 mm with external adjusters * Automatic Iris to cope with High levels of illumination with negligible smear, passes more light and provides greater
depth-of-field than ordinary fixed Iris Lenses, external Iris control &
Video Output for Setup Monitor * Corrected for
major Visible-Infrared focus shift, there may be
a slight shift that requires a compromise or choice between crisp colour or crisp monochrome
*
Under some
lighting conditions internal reflections between Lens &
Front Glass may appear in image, these are usually insignificant * There are no
Accessory Lenses for this Camera,
additional
CCTV Lens information.
Scanning System: 2 : 1 Interlace, PAL 50 Hz
vertical, 15 625 Hz horizontal.
Synchronisation: Internal.
Video Output: 1.14 V p-p Composite Video 75
ohms, suit Australian TV, VCR, AV & Video inputs, BNC socket, Cable ~ 40
cm exits through Bracket for concealment and protection against
tampering. EXTRA Video Output for Setup Monitor behind
threaded Back Access Cap, RCA socket.
Horizontal Pixels: 700 + (this value
is provided for comparative purposes only) Better than VHS &
Super-VHS near DTV / DVD (720 pixel) resolution.
Minimum Illumination: ~ 5 lux (this
value is provided for comparative purposes only), 0 lux with LEDs 'ON'.
Depending on Lens 'focal length' setting the Infrared LEDs illuminate up to ~ 90% of the Width-of-Vision and are effective up
to ~ 25 metres depending on the Infrared reflective characteristics of
subject, objects closer than ~ 3 metres may be overexposed when illuminated by
LEDs.
Light Emitting Diodes: 48 pieces ~ 850 nm wavelength
Infrared, these produce a dull Red visible glow. Automatic Light Sensor switches LEDs On/Off
(~15/30 lux) depending on light level.
Movable Infrared Cut Optical Filter:
Colour sub-carrier is turned off (Colour-Killer) to improve Signal to Noise Ratio
when IR-CUT filter is out of optical path (LEDs On).
In Day mode (well lit, colour) mechanism automatically
positions IR-CUT optical filter between Lens and Image Sensor to exclude
Infrared radiation that would otherwise adversely affect colour reproduction,
this ensures colour rendition not possible with ordinary
non-filtered or notch-filter type Day/Night cameras.
In Night mode (low light,
monochrome) Colour-Killer
is activated and mechanism automatically removes IR-CUT optical
filter to allow Infrared radiation to pass boosting low light and Infrared
sensitivity, the result is significantly better night images using inbuilt
Infrared Illuminator or
with Infrared rich light sources. Infrared Response
without Infrared filter
is ~ 700 to ~ 1100 nm better than
a
'CCTV
notch IR Filter' filter,
additional
CCTV Infrared Night Vision information.
Automatic Electronic Shutter (AES): 20 milliseconds, low shutter speed eliminates smear associated with High Shutter Speeds necessary
to control exposure with fixed iris lenses,
additional
CCTV Automatic Electronic Shutter information.
Spectral Response: ~ 400
to ~ 1100 nm with Infrared 'CUT' Filter 'out' of optical path,
additional
CCTV Infrared Night Vision information.
Signal to Noise ratio (SNR): 50 + dB, measured with AGC off.
Automatic Gain Control (AGC): Switchable
On/Off, behind threaded Back Access Cap, default and recommended setting is ON.
Back Light Compensation (BLC): No,
the switch on the Back of this Camera is disabled with Automatic Iris
Lens version, (switch is used with fixed Iris Lens version not stocked).
Gamma: 0.45.
Automatic White Balance (AWB): 2100ºK
~ 9100º, Colour sub-carrier is turned off to improve Signal to Noise
Ratio when IR-CUT filter is out of optical path (Night
Colour-Killer mode, low light, monochrome).
Power Requirements: 12 Volts DC Regulated, ~
1000 mA Peak (LEDs = On & Filter Moving), ~
900 milliamps with LEDs On, ~ 190 milliamps with LEDs Off, 2.1 x 5.5 mm DC socket, center pin = (+),
Cable ~ 40 cm exits through Bracket for concealment and
protection against tampering. Consider cable resistance when installing,
ask us about solutions if voltage drop is a problem with pre-existing wiring.
Made in Korea.
Dimensions: Camera: ~ 88 mm Diameter, ~ 120 mm
Long. INTEGRAL Bracket: ~ 65 mm base diameter, ~ 105 mm high, ~ 35 mm pivot
shaft. Camera & Bracket ~ 1100 grams. Visor: ~ 165 mm x ~ 106 mm, ~ 220 grams.
