Analog HD - AHD 1080P
technology is the latest development in the analog CCTV industry and is
supported by all models in this range.
Launched in May 2014 by Nextchip,
worldwide leader in DSP for CCTV cameras, AHD technology brings analog
cameras up to FULL HD 1080P (1920x1080)
video resolution. Before AHD, megapixel resolution was only possible using
Connected to latest generation
these cameras provide megapixel resolution, with no latency, still being low
cost and easy to install as standard analog cameras.
Like any analog cameras, AHD
cameras can be wired by normal coaxial or twisted pair cables up to several
AHD cameras are still compatible with old DVR, like 960H and D1, providing the same performance of 1000 TVL
4 in 1 (AHD/CVI/TVI))
cameras in this range are also called: 4 in 1 cameras
because, besides AHD and CVBS, they support CVI and TVI technologies as
CVI and TVI are high resolution analog technologies, similar to
AHD, but adopted by other manufacturers like Dahua and Hikvision.
Thanks to 4 in 1 chip,
these cameras virtually suit any DVR, of any brand or period.
High CVBS analog video resolution
All cameras in this range are able to produce a composite video output (CVBS)
suitable to any DVR or monitor.
AHD cameras provide 1000 TVL
when used in CVBS mode.
Camera built-in PIR burglar detector
These cameras are hidden in false burglar detectors. The camera films through a tiny hole on the front of the cover
that looks like the PIR LED.
The infrared illuminator for night view is
hidden behind the Fresnel lens of the detector and is not visible from
These cameras can be
easily oriented using the convenient swivel mounting bracket.
There are 2
versions of this product: with and without audio.
All these cameras come with a special pin-hole lens for concealed use. This type of lens is able to film through a 1 mm hole, and is
therefore perfect to make hidden cameras.
Cameras are supplied with 3.6 mm pin-hole lens, which offers a wide-angle
view able to fully cover an average area.
20 m. IR - 940 nm invisible LED's
DSE IR standard cameras use 850 nm IR LED's
The infrared light cannot be seen by human eyes, but in spite of that, you
will see a lot of red dots if you look at the camera at night.
In this models, developed for hidden surveillance, we do not use standard
LED's, but special 940 nm LED's that do not generate any
visible light even in total darkness.
Featuring Day&Night function, all these cameras gives color picture during
the day and turn to B&W at night. The IR LEDs turn on automatically as soon
as the light drop below 0.3 Lux.
The IR illuminator of these cameras is
hidden behind the sensor lens allowing up to 20 m. illumination range.
RE-TCN8FD4RA come with a built-in microphone for audio.
without microphone, audio feature can be added using an external microphone
DSP with OSD
The video processing of all cameras in this range is controlled
by a DSP microprocessor. All cameras
come with On-Screen-Display (OSD) which allow the user to set several camera
Setting the OSD options,
the camera can be configured to perfectly suit any environmental conditions.
Following main features are available to be set:
VIDEO ADJUSTMENT - Lens type, electronic shutter, AWB, AGC,
brightness, contrast etc. can be adjusted according to the environment.
NOISE REDUCTION - Digital video noise reduction
for low-light or poor video signals (3D)
- Compensation of areas with different light level, like rooms with windows
A mini joystick remote
control, conveniently placed along the camera cable, allows scrolling the On
Screen Display (OSD) and set all the advanced features of the camera.
This control is also used to switch between AHD/CVI/TVI/CVBS mode.
OSD remote control via UTC
The OSD button on the camera becomes very often hard to use once the
camera is installed.
In order to allow the user to modify the OSD options
conveniently at anytime,
all DSE OSD cameras include a UTC chip which
permits to control the OSD from the other end of the video cable.
DVR include the UTC function and allow to set the camera OSD sitting
in front of the monitor.
Like all analog cameras, these cameras can be
connected by wires to any monitor, TV or, more often, video-recorder.
A 50 cm. cable with DC Plug, BNC female video connector
and RCA audio female connector (if available)
comes out from
the back side of the camera.
A 220VAC/12VDC power adaptor, like
RE-AL4S, can be connected to
the DC plug to power up the camera. Min 1000mA, fully
regulated, power adaptor is required. Should you prefer to provide the power from a central point you can order a
power supply unit in metal casing.
Should the adaptor be placed far from the camera, an adequate section of the
power cables must be used due to the considerable power consumption of the
IR LED's board.
Video signal must be hard-wired to TV/Monitor/DVR using RG59 or RG179 coaxial cable
(see cables). Coaxial cable must be terminated
with BNC male connectors. Alternatively, the video signal can
also be wired using a twisted pair installing on both ends two
AHD cameras connects exactly as all other analog cameras, but provide HD
resolution only with AHD DVR. All AHD 4 in1 cameras can be switched to CVBS
(standard analog video) or even to CVI and TVI in order to connect to any DVR from other vendors.
All these cameras can be converted to wireless cameras using an
