Dahua Starlight Anti-Corrosion IR Dome Review - camera hải nam tphcm

1. Dahua Starlight Anti-Corrosion IR Dome Review - mua camera hải nam Dahua's IPC HDBW823EP-Z-SL is a 2MP, Starlight, anti-corrosion dome including a 1/1.9- inch 2MP progressive- scan CMOS sensing unit, 120dB of WDR ability, delivering 60ips at 1080p, a 4.1-16.4 mm motorised lens, 50m of IR, IP67 as well as IK10 ranking as well as H. 264 and also H. 265 compression alternatives. Efficiency matches the attribute set. - camera hikvision hải nam DAHUA'S IPC HDBW823EP-Z-SL is hewn from a lump of 316L stainless-steel as well as the prompt impression you obtain when you hold the electronic camera in your hands is develop quality. It's tough, the finish is outstanding, there's potting of terminations in the electronic camera chassis, rubber climate seals, sprucing up of metal as well as the bubble appears to be mainly untinted. Best of all, sensor efficiency very closely matches the superb specification. Dahua's 2MP Starlight video cameras are strong performers yet this new launch appears to be the very best we've ever before tested. The electronic camera has a 4.1-16.4 mm motorised lens with a magnesium-fluoride coating (550nm) and a maximum aperture of F1.53-- simply put, it's a great lens. But prior to we get into out testing, let's run through some electronic camera specs. At the heart of this video camera is the 2MP 1/1.9- inch progressive scan CMOS sensor, supplying 1080p at 60ips and also 120dB of WDR. Minimum scene lighting is claimed to be 0.002 lux in colour at 1/3rd of a 2nd and also 0.01 lux at 1/30th of a 2nd. Frankly, 1/3rd of a second shutter rates are extra imaginative than helpful with moving objects-- you will certainly obtain significant activity blur. Nevertheless, in fixed scenes you'll obtain great detail, consisting of plates-- and you might get static faces, particularly if there's extra light tossed onto them by mobile phone usage. Potted terminations-- not something you see on lots of CCTV cameras ... Signal-to-noise proportion is higher than 50dB, IR variety is up to 50m, angle of view is 92 degrees at the broad end and also 32 levels at the lengthy end, the video camera framework has up to 355 levels of turning. There's a microSD card slot and you user interface with the video camera through web visitor (I start with CMS DSS after that make use of web customer), CMS( DSS/PSS) and/or DMSS. When it pertains to smart video analysis, the cam uses tripwire, invasion, things abandoned/missing and there are innovative intelligent functions including face detection, people counting as well as heat map. Video compression options consist of H. 265+/ H. 265/H.264+/ H. 264 in 3 streams as well as audio compression (in/out) is G. 711a/G.711 Mu/AAC/ G. 726. There's little bit price control through CBR/VBR, BLC, white equilibrium options including; car, natural, street light, outside and also handbook. There automobile as well as hands-on gain control, car and guidebook noise reduction, 3D DNR, activity detection alternatives including off/on in 4 rectangle-shaped areas, region of rate of interest and personal privacy masking, both in 4 rectangle-shaped areas, electronic images stabilisation, de-fog, 16x electronic zoom, flip alternatives consisting of 0, 90, 180 as well as 270 degrees-- I'm using 180 levels for this examination. Other attributes consist of a complete variety of network safety attributes, an alarm system input, ONVIF, PSIA, CGI compatibility and IOS as well as Android assistance. Power usage is less than 18W, running temperature is -40 to 60C. Measurements are 162.3 mm x 118.1 mm as well as weight is 3kg. As discussed, this PoE cam is a tough ape, ranked to IP67 and IK10. Driving the Dahua HDBW823EP-Z-SL We're performing the examination on SEN's Dell Optiplex 9020, which features an i7 cpu with 8GB of RAM. While this is not an especially high-spec web server on the GPU side, the Dahua manages completely well with it,

2. recommending a relatively lightweight handling need at 2MP and also 60ips. Customarily, we're powering the camera through a standard Netgear ProSafe GS108P button. There's nothing else operating on the server or the network to cause latency or headaches. Configuration is easy, once I get my IP address range properly matched. Remember in the late afternoon and also night shots, the clock on the image display is readied to daytime saving time-- it's a hr in advance. It's mid-day when I start the examination and also the day is a little dirty yet I obtain a common sense of electronic camera efficiency as soon as I hang this camera on the terrace and sit down at the workstation. This large sensing unit drags in a great deal of information-- the representations in the paintwork of vehicles on the street, information of trees as well as pedestrians. Something else I observe immediately is deepness of area at bigger angles of sight-- I go to around 5.5 mm a great deal of the time in this examination and also the depth of area is top quality. I placed it to lens intensity, sensing unit quality as well as advancement of Dahua's WDR handling formulas. Distortion is around 6 per cent at the vast end-- it's gone by 5.5 mm. I don't see any colorful aberrations at all, which is a big deal since it suggests Dahua is paying severe attention to lens quality in-house. Relatively small things like this speak of a society of top quality manufacture. I watch on bitrate throughout the examination-- it's around 6200kbps most the moment, despite a lot of movement in the scene. When you have actually got a motorised zoom lens it's hard not to utilize it. Lens performance in regards to zoom as well as autofocus is extremely excellent. After using the zoom slider, re-focus is just about a 2nd behind-- that's fantastic for real-time job. The 4x mechanized zoom is perfect for a fixed PTZ such as this however you require to take care with mounting elevation and also main angle of view, it's fairly easy to zoom also much with a fixed zoom cam, particularly if it's looking downwards. I end up tilting the camera back on its buttocks in the magic arm in order to raise the perspective to assist enhance my range with optical zoom-- you can do this by tweaking the electronic camera body inside the real estate, too, however I take the easy out today. My settings are usually default with whatever on car. I see there is some over direct exposure on the sunny side of the street my default settings can't take care of yet the balance between bright and also dark is managed extremely well. Over direct exposure reduces detail. When the sunlight moves away a little, deepness of area really opens up-- I'm talking between 40 as well as 80m at the wide end of the lens. I can't obtain plates of quick moving vehicles at the broad end as the afternoon darkens. Unlike lots of low end 1080p electronic cameras, electronic zoom well worthwhile-- I get value out of 6 or 7 rolls of the computer mouse wheel-- 16x takes me to pixellation yet at more sensible degrees, it's exceptional performance. - mua camera hải nam Encounters remain with me as the lights falls-- in some cases they don't-- as well as this is very pleasing. You obtain court acceptable faces out previous 12m with this video camera at 4.1 mm-- within this range, faces are assured. This is all to photo top quality from lens as well as video camera system. The big sensor suggests higher pixel spread at 4.1 hikvision giá rẻ mm, remember. Experiencing the pictures later on, I believe I'm obtaining differentiating facial functions at 20m with the lens established vast-- that's excellent. - công ty camera hải nam Plates are gone at 5pm (time on screen is an hour fast ...). When I most likely to the long end with the lens, intensity improves, though I shed my depth of area thanks to camera angle. At the lengthy end, also in stopping working light and with minimized aperture, faces are brilliant. When I return to large, a vehicle goes as well as again no plate, yet everything else is clear-- no tone mapping, no rocket tail of mid-processed pixels-- it's a well-founded picture. At about 5pm I start obtaining some blur with rapid relocating automobiles as the shutter slows down as well as this influence on faces as well as relocating legs, as well. Strolling pedestrians are still fantastic but when a lady diminishes the street, no face acknowledgment. With the cam secured colour and also colour rendition, which was solid all afternoon, hangs together at 7 lux in low stress salt streetlights. Under the low-pressure lights colours tends to yellow orange yet the following light up

3. appears to be LED and also the colours are really real without false colour. At one mention here, an auto front lights captures the camera and also there's obvious flowering however control of growing is typically, excellent. Overall capability to hold colour in really dark problems is exceptional-- there's a cost in the slow-ish shutter rate yet the reduced light capability is excellent-- it remains strong with pedestrians and also face acknowledgment is readily available in colour in below 10 lux bent on 10m-- additionally if there's some environmental light of the type I have in this scene. Skin tones are solid, too. Relocating cars and trucks are more difficult to handle-- there's a factor in the mid-day when you are no more able to protect plates and also later blur rises however it never ever seems unmanageable. Something that's good is the absence of tone mapping around moving objects till points are fairly dark. Control of blooming is remarkable as light falls. There are 4-pointed aperture celebrities. Fixed plates are wonderful, also. Deepness of field remains good right into the evening, as does detail. For a 1080p electronic camera, information is very high certainly at broader angles of view. This is a fine camera for the many applications that are heavy on foot web traffic during the night. Next off, I have a look at monochrome performance and also hopping right into the browser, I lock the cam into night mode. Again, information degree is abnormally high for a 2MP, As you 'd anticipate, detail is greater in grayscale as well as movement blur is considerably lowered, also. For typical street-lit scenes such as this one, you 'd most likely leave IR off. I additionally find that zoom is equally as powerful in black and white as it is during the day. Comparison in grayscale is great providing big information as well as boosting DoF. I commonly point out that monochrome performance is best after dark and below it is once again, with strong information all the way to 16m. In black and white, face acknowledgment goes out to regarding 12m and also is high quality inside 10m. During this test, I head out front and also I'm shocked by just how dark it is-- on-screen points are much better. Something I notice is some fascinating ghosts as well as flare in the lens and bubble-- while there are a few of them, they are very portable as well as you need straight light to generate them. In justness to the electronic camera, I have it mounted at an uncommonly high angle Mắt camera Hikvision to the source of lights (car fronts lights) in this scene. At one point too, I notice growing from a direct hit of a front lights-- it's the dome in my viewpoint, not the sensing unit, which is what you desire. Another thing that's visible is the control of noise-- it's extremely, great regularly, no matter the light degree. I get a little pulsing in mono but you need to pixel-peep to see noise. In my opinion, this suggests Dahua has actually mosted likely to an additional level with the design of this camera system-- it's the most effective Dahua camera we have checked by a substantial margin.

4. This veiling flare is taking place at 9.30 am-- as reviewed at SecTech Video camera Shootout, early mornings and also mid-days can be tough. Following day I get going early to make sure solid backlight and also while the video cameras handle WDR very well, the bubble finds it a tougher gig showing lots of veiling flare-- that's regular for a dome yet worth bearing in mind throughout commissioning if you plan to wall surface place e, ternally. I still have the dome angle in reverse, which is unfair on the electronic camera. The flare is greatest when zoomed in-- when I draw the lens back to a larger angle of view, the pressure comes off. There's likewise a strong purple ruby ghost in the centre of the picture which is coming from the front element of the lens. Despite these fairly generic dome bubble issues, WDR performance is outstanding, as is the lack of CAs-- great job from Dahua there. The adjacent intense and darkness job is very good, as well, as well as I have moving plates looking into about 80,000 lux. There's no drama recognizing Norman's face or plate in this strong backlight and making use of optical zoom you can dig a long way into this street scene. You can see the ruby aperture ghost beside Norman's emphasis assist ... Total, this is an outstanding dome that's widely tough and includes a wonderful spec. Performance from the 2MP 1080p sensing unit matches the specification, which is beautiful to see, and the motorised zoom and also super- fast emphasis provides the cam more power still. The best features of this cam consist of reduced distortion, virtually no CAs, Capability to hold colour while retaining faces to 10m under 10 lux, excellent monochrome performance and a noteworthy absence of sound. This is the most effective 1080p dome we have actually examined at SEN and the best executing Dahua cam we've examined, as well. Dahua's technology is developing-- absolutely worth an appearance. ♦. - mua camera hải nam Functions of the Dahua 2MP Starlight dome consist of:. * Large 1/1.9- inch CMOS. * H. 265 & H. 264 triple-stream encoding. * 60fps@1080P. * WDR( 120dB), Day/Night( ICR), 3DNR, AWB, AGC, BLC. * Really qualified 4.1 mm ~ 16.4 mm motorized lens. * IR variety of 50m.
