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.

Dome camera Dahua DH-IPC-HDW1020SP-S3 is sharpened for use in outdoor and indoor video surveillance systems. The use of the model outdoors is possible due to the high degree of water protection IP67 and unpretentiousness to temperature extremes (from -30 °С to 60 °С).

Filming on the camera is made in HD-resolution (1280x720 pixels) with a frame rate of 25 fps. By the standards of digital cameras, this is not much, but with an eye to the democratic cost of the model, it is quite acceptable. Image capture is occupied by a fixed lens with an 85 ° field of view and f / 2.5 aperture, and the care of image formation is shouldered by a 1/4-inch CMOS matrix.

At night, the LED IR illumination with a range of “finishing” rays up to 30 m helps to see objects within the controlled perimeter. WDR (extended dynamic range), AWB (auto white balance) and noise reduction technologies also help to improve the visibility of the picture. 3DNR. The camera's additional assets include a motion detector, and separate ROIs allow the operator to control specific areas of the image in a higher quality in relation to the overall situation in the frame.

Dahua DH-IPC-HDW1020SP-S3 supports H.264 and H.264+ dual-stream encoding, which helps reduce bandwidth. The footage is written to a local disk or directly to the "cloud", moreover, you can control the camera and view the picture from it remotely. Another argument in favor of the model is ONVIF compatibility with third-party video equipment. She would have had a stronger case and a more affordable option with such a developed level of functionality would not have been found at all.

Whereas Hikvision 's main product line of security cameras is focused primarily on the business segment, the Ezviz series of devices will show itself to the best extent in everyday life. All representatives of this family are distinguished by ease of installation, configuration and further use, which is confirmed by the example of the C4S model.

The key difference between the camera and its colleagues in the “dome” workshop is the absence of the need for a network cable, since the model communicates with the command and control center via a Wi-Fi network. The main thing is that a consistently good signal from the router should reach it, and then there will not be the slightest problem with the transmission of the video sequence.

“Dancing with a tambourine” is not required to set up the camera - everything is done in just a couple of movements in the Ezviz mobile application or the Ezviz Studio desktop programme. They provide access to view the video from the model in real time. By the way, the videos are recorded on a camera with FullHD 1080p quality. In advanced settings, the user has the right to set a command to start recording video when movements are detected in the frame.

A detailed picture in varied lighting conditions is provided by a matrix with WDR technology (expansion of the dynamic range by software) and powerful IR illumination. The “eye” of the camera recognizes objects in complete darkness at a distance of more than 30 m. Also, you don’t have to worry too much about the intervention of intruders, since the body of the model is protected in accordance with the requirements of the IK10 anti-vandal standard.

The balance of price and functionality is an important quality when choosing any product, whether it is a technologically savvy smartphone or, for example, an outdoor video surveillance camera. Like Honeywell HEW2PR1 dome model.

The camera captures what is happening on the electronic “film” of a connected computer or DVR in FullHD resolution (1920x1080 pixels, 25 fps), which was made possible thanks to a solid 2 MP 1/2.7" sensor. Lux, and this, for a moment, is the level of a dark night illuminated by the light of the moon.When it’s completely “gouge out your eye” on the street, by the way, you will need IR illumination with a detection range of objects in the frame of about 40 m.

The protection class of the body of the model is designated as IP66, which means that the camera is completely devoid of fear of dust and moisture. The Honeywell HEW2PR1 also does not make any special demands on ambient temperatures, coping equally well with video shooting both on frosty winter days (down to -30 ° C overboard) and in hot summer heat (up to 60 ° C).

Power is supplied to the camera in two ways: from a 12 V source (the block must be purchased separately) or directly via a network cable (POE technology). Afterwards , the model is equipped with a motion detector and is ONVIF-compatible, i.e. able to work in tandem with any security equipment that supports this standard. The very place of the camera is in the courtyard of private households, commercial facilities and other structures, near which it is necessary to deploy round-the-clock monitoring of the situation.

Hailing from the Middle Kingdom, Hikvision has barely come of age (the brand was founded in 2001), but its name has been widely known on a global scale for more than a year. We are talking about the field of video surveillance, in which the Chinese manufacturer has pretty succeeded.

For outdoor perimeter monitoring, Hikvision's portfolio has many interesting offerings. In particular, the dome IP camera DS-2CD2125FHWD-IS, stuffed to capacity with all sorts of "goodies". The all-seeing "eye" of the lens of the model captures a clear picture in the field of view, regardless of the external lighting conditions - whether it is a bright sunny day or a pitch-black darkness. In the latter case, the built-in IR illumination with a beam penetration range of up to 30 m is responsible for ensuring the visibility of the image.

In the hardware part, the camera is equipped with a 1/2.8" light-sensitive CMOS sensor with a resolution of 2 MP, which allows you to shoot Full HD videos, and even with a high frame rate (50 fps). Technology- Image "improvers": WDR (software dynamic range expansion), BLC (backlight compensation), 3D DNR (combats noise), ROI (increases the resolution of a certain area), etc.

A weighty argument in favor of the model is the presence of a motion detector on board. With it, you can programme the start of video shooting when movement is detected in the field of view of the lens. Moreover, the intelligent algorithms of the electronic “brain” of the camera are able to recognize faces and find things left in the frame. Control of video recording parameters and remote monitoring are possible both from a PC PC and from a connected smartphone.

The Hikvision DS-2CD2125FHWD-IS is powered from a 12 V DC source or using POE technology (directly over twisted pair). Also, the model is unpretentious to operating conditions - the camera's performance is maintained in a wide temperature range (from -40 ° C to 60 ° C), in the rain (IP67 water protection class), in addition, the body of the device is dressed in strong anti-vandal armor.

A professional tool for deploying a video monitoring system from a well-known player in the network equipment arena represented by D-Link is ranked among the top solutions for the street front, which do not care about the vagaries of weather, malicious attacks and ambient lighting conditions.

At the heart of the DCS-6517-A1A model there is a 1/3.2" 5 MP photosensitive sensor, which allows shooting in high resolution 2560x1920 pixels. A varifocal lens with a set of focal lengths of 3-10.5 mm and a maximum aperture of f / 1.4 is working hard with the sensor.

The camera sees perfectly not only in the daytime, but also at night - the ICR filter flexibly adjusts the sensor's sensitivity to the actual lighting, and thanks to the presence of IR illumination, objects in the frame are clearly distinguishable even in complete darkness at a distance of up to 20 m. The camera is able to "read" faces and license plates, incl. with strong differences in illumination in different parts of the frame, the merit of which lies on the shoulders of the WDR dynamic range expansion function.

In terms of decoration, there are not so many equal to the D-Link DCS-6517-A1A. The camera provides the user with a built-in POE module for supplying power and connecting to the network via a single Ethernet cable, audio input and audio output for organizing two-way voice communication, similar alarm interfaces and, of course, a motion sensor with zone detection. This wealth is packed in an all-protected case with a total weight of over 1 kg. The only “but” is the immodest price tag of the model. But for a flagship-level product, the high cost is forgivable.
