The cameras in this range are analog high-resolution AHD CCTV cameras. With these cameras you can create a modern and high-performance video surveillance system while maintaining the simplicity and reliability of traditional analog CCTV. AHD technology is the ideal solution for hidden surveillance because the size of the cameras can be really tiny, much smaller than IP cameras.
With the AHD (Analog High Definition) technology, the old low resolution analog video has retired. Combined with AHD digital video recorders , these new generation cameras offer you all the megapixel resolution and remote control capabilities of our digital IP cameras, but in analog technology. An AHD camera does not require configuration like an IP camera: it connects and works immediately. If you want to know more about AHD, follow the video tutorial that we recorded in 2014, presenting, first company in Italy, this innovative technology. Below you can see the basic diagram of a small AHD system.
Most of our AHD hiddewn cameras are actually 4 in 1, which means they can provide 4 types of video signal. The AHD signal is our main format for high resolution analog video. AHD is the most popular format worldwide and is an international standard that allows you to use our AHD cameras with any brand of AHD DVR. CVI and TVI, also called TurboHD, are similar to AHD but used by other manufacturers. You may use these video formats if you connect our cameras to other DVRs. CVBS is the old analog, low resolution video. You have to switch the camera to CVBS mode if you want to connect to analog monitors or old DVRs. You can switch the video signal of the camera by yourself if you have a DVR supporting UTC control. If you are not sure your DVR has this feature, please specify the video format you need while ordering .
These micro cameras come with 2 connectors: BNC for video and 12VDC power plug. A few models also include an RCA output for audio. You can provide 12V power with an adapter near the camera or with a centralized power supply unit. Choose from our range of DC power supply units the best solution for your system. You can transfer the video signal with coaxial cables. Alternatively, you can use CAT5 network cables, by adding small converters called balun .
Several models in this range also have a built-in microphone that you can connect to the audio input of the DVR. The cable used for audio wiring is very often a simple cable pair. If you buy combined cables, with a coax + two twisted pairs in the same sheath, you can connect these cameras using just one cable.
These hidden cameras provide high-resolution video, absolutely comparable to our bigger cameras. The 2MP resolution, also called 1080P or Full HD (1920x1080 pixels), is the current standard of high resolution digital TV and guarantees excellent clear video. If your budget is higher, you can consider our 5MP cameras, that provide more details when zoom-in. You can downgrade our 5MP cameras to 4 or 2 MP if required. All cameras support the old, low resolution, CVBS video standard. Here you can download a few video clips in the most common video resolutions.
These cameras provide excellent view with minimum natural light up to 0.01 lux. To monitor in total darkness, burgler detectors cameras range are equipped with a small infrared illuminator that provides night view up to 20 METERS range. The LEDs turn on automatically when light drop below 10 lux. These hidden cameras come with special LEDs at 940 nm , absolutely invisible to the human eye, which do not produce the classic red dot of normal LEDs. In night mode the camera turns to Black&White.
AHD cameras have many advanced settings, like IP cameras. You can adjust the camera settings with a pushbutton on the cable. If you have a UTC DVR, like our RK Series DVR you can adjust the camera menu remotely. A convenient on-screen menu allows you to fine-tune the image settings in order to suit the area to be monitored. The WIDE DYNAMIC RANGE (WDR) function is useful if you shoot bright areas together with darker areas. With the BLC you can enhance dark subjects on bright background. The DIGITAL NOISE REDUCTION allows you to cut down video noise in low light conditions.
These cameras are hidden inside fake burglar and fire detectors. You can install them in a corner of the room and monitor the environment discreetly. Both models allow you to orient the camera, changing the direction and the vertical angle of the lens. The burgler detector camera include a wall-mounting bracket, while the smoke detector camera is installed directly on the ceiling.
All these hidden cameras come with 3.7mm lens which provides the classic wide angle view of about 70°, suitable for an average room. The alarm detector come with a pin-hole lens, while the smoke detector have a mini-lens hidden behind one of the side slits of the sensor.
These AHD cameras are designed to be connected to a digital video recorder , also called DVR, which has the task of digitizing and recording the video signals of the analog cameras. With the video recorder you can perform all the digital functions of IP systems, like remote control via Internet or motion detection. The cameras in this range are compatible with all AHD DVRs, but we recommend, for maximal compatibility, our RK DVR.
