Perimeter control: TOP-5 dome cameras with motion sensor

The Chinese brand Hikvision has made a name for itself in the production of high-quality video surveillance systems for home and commercial formats. The DS-2CD2120F-IS IP camera is one of the worthy examples for perimeter security monitoring both in the yard of a private household and on the territory, for example, of warehouses.

The camera works in the sweat of the day and at night - thanks to the IR illumination, which automatically turns on when the permissible illumination limit decreases, the model calmly tracks night movements in the frame at a distance of up to 30 m. Configurable zones with priority surveillance (including when motion is detected) are placed in proprietary software for controlling the camera by individual programme items.

According to the rules of good manners, the video is recorded by a camera in FullHD format (1920x1080 pixels, 25 fps). But as for optics, the model is presented on store shelves with lenses of 2.8 mm (viewing angle 90 °), 4 mm (79 °) and 6 mm (52 °). Here, take into account the position of the camera installation. In all configurations, the Hikvision DS-2CD2120F-IS lens has a fixed focal length and a maximum aperture of f/1.2.

Bypassing the extra links in the chain in the manner of a DVR or computer, you can record video directly to an SD flash drive (up to 64 GB). With the active motion detection function , the memory card will be filled to capacity after a few days or even weeks. An additional trump card in the sleeve of the model is POE power (over a network cable). On top of that, the camera deserves praise for its relatively affordable price tag, as well as dust and moisture resistance, which is confirmed by the IP66 rating designation.

The Atis branded outdoor camera monitors the perimeter of the territory as part of security video surveillance systems, providing access to settings and video images from any corner of the globe where the Internet is available.

In the simplest case, the camera is connected directly to the PC via a twisted pair cable. Getting the most out of it will come out in conjunction with IP DVRs that support POE technology (power transmission to network devices directly through a LAN cable). On the network, the camera receives a unique IP address, which makes it possible to approach it from anywhere. Also, the model is able to work on the same wavelength with mobile devices running iOs or Android.

In this case, the 2 MP Sony Exmor IMX323 1/2.9" matrix is busy with the formation of a FullHD image. The use of this sensor allows the Atis ANVD-2MFIRP-30W Pro to be successfully used in high-definition video surveillance systems. varifocal lens with a focal length range of 2.8-12 mm Video is recorded by the camera with a frame rate of 25 fps in H.264 and AVI codecs, thereby maintaining high image quality with a relatively small file size.

Video filming can be programmed when motion is detected in the frame. Also, the camera copes well with tasks shouldered in the dark. Fortunately , the built-in IR illumination “finishes” at a distance of about 30 m. Another plus in the karma of the model is the level of protection against dust and moisture IP66. The case of the device easily withstands high humidity and low temperatures, but has a non-shockproof design. And this is the only complaint against him.

Tecsar is one of the generally recognized leaders in the domestic market for video surveillance systems. The keen “eye” of the camera with the name IPD-L-2M30V-SDSF-poe, which is difficult to remember, is able to detect movements in the frame, look around the perimeter into the hopeless darkness, and even deal with video analytics. But first things first.

The camera in a high-strength metal "body" is designed for outdoor installation and operation within the temperature range from -35 to 60 °C. The degree of protection of its body from dust and moisture is marked IP66, and the camera is protected from damage attempts in accordance with the requirements of the IK10 standard, which corresponds to the preservation of the device’s performance when a 5-kg load falls on it from a height of 40 cm. Due to the support of POE technology, power is supplied to the camera can be connected directly via the network cable.

The electronic heart of the Tecsar IPD-L-2M30V-SDSF-poe is a 1/3- inch CMOS matrix with a resolution of 2 MP. In close cooperation with her, a lens with a set of focal lengths of 2.8-12 mm is working. At the output, the user receives a picture with a maximum resolution of 1920x1080 pixels, which is compressed using the H.264 and H.265 codecs. In the dark, an effective IR illumination system with a range of up to 30 m is put on guard for the visibility of the image in the frame. The camera switches the shooting mode “Day / night” automatically.

Video recording in conditions of strong light differences is not an easy task. But it is given to the camera without much difficulty. The reason for this is the WDR dynamic range expansion technology, which allows you to better convey details in the penumbra and bright areas of the frame. The list of significant advantages of the model continues with the functions of motion detection and crossing the boundaries of the delineated safe perimeter zone. The camera also reacts to attempts to defocus or close the lens, showing itself exclusively from the best side as an integral part of a professional CCTV complex.

Remote camera control and video monitoring are performed directly from a smartphone with a pre-installed EZTool application. Even more all kinds of "goodies" were brought to the web interface of the camera (setting up audio detection, sensitivity zones, access to different users, etc.). In places without means of communication or remote from civilization (for example, in the country), by the way, you will have the opportunity to record video on a microSD card(including cyclic). In terms of the set of parameters, the brainchild of Tecsar claims to be one of the most balanced models in the strong middle class of CCTV cameras.

D-Link is one of the world leaders in the networking and telecommunications equipment industry. One of the brand's fields of activity is outdoor video surveillance systems. The DCS-4602EV/UPA model is a good example of a good 24/7 monitoring camera.

The camera in a dome-type body is equipped with a highly sensitive 1/3" CMOS sensor with a resolution of 2 MP. 60 °, and horizontally - all 350 °.The video is recorded by the camera in the maximum resolution of FullHD (1920x1080 pixels) with a frame rate of 30 fps, which is quite enough to render a detailed and smooth picture.

In conditions of uneven lighting (for example, in order to identify objects in backlight), the supported WDR technology will be useful - expanding the dynamic range of the image by software. Also, the camera sees the perimeter well in complete darkness - the rays of the built-in IR illumination provide a viewing range of up to 20 m.

The camera is controlled and configured through proprietary D-ViewCam software. It is possible to view images from up to 32 connected cameras. After delving into the settings, the user has the right to activate video recording by detecting motion in certain areas of the frame. In parallel, the camera reports unusual activity by sending an email notification.

The tightness of the body of the model meets the high standard of protection IP66. And the vandal-proof design protects the camera from malicious encroachments. D-Link DCS-4602EV/UPA can be called an excellent option for building high-quality outdoor video surveillance systems powered directly by twisted pair, which is much more convenient than laying a separate wire or fiddling with autonomous power sources.

It is a well-known fact that the products of the German brand Bosch have long become synonymous with high German quality and reliability. The NDN-50022-A3 digital camera from the upper strata of the society of outdoor video monitoring systems was no exception to this rule.

The dome camera is designed for outdoor use. The protection of its internal "stuffing" from the vagaries of the weather is implemented in accordance with the IP66 class. Moreover, the body of the product is not afraid of frost down to -40 ° C and is resistant to vandalism. When trying to damage or block the visibility of the frame, the camera sends an alarm signal to the control panel.

"At the helm" of the model is a progressive CMOS-matrix of a solid size 1 / 2.7 ", which to a certain extent guarantees a high-quality result. The minimum threshold of its photosensitivity at 0.05 Lux allows you to shoot even in extremely low light. In conjunction with the image sensor, a lens is used f/1.3 with focal lengths of 3-10mm.

A whole galaxy of external factors always strives to interfere with the holistic perception of the picture. To effectively suppress them, a number of image “improver” technologies have been put into service with the model: D-WDR (dynamic range expansion), AWB (automatic white balance adjustment), iDNR (noise reduction), BLC (backlight compensation). In parallel with the picture, the camera records sound, and with the help of a microphone and speaker, it is possible to organize two-way audio communication.

The list of advantages of the model is truly inexhaustible. MOTION+ motion sensor, data saving to an SD flash drive, POE power supply, compatibility with any ONVIF equipment - this list can be supplemented with more than one trump card. The price for such advanced camera functionality was a high cost. However, the brainchild of Bosch fulfills it in full with the video surveillance capabilities provided.
