over the years I’ve tried a lot of CCTV cameras. things have come a long way as we moved from coax, CRTs and BNCs to CAT6, IP and PoE.

This time I wanted to organise a new pan Tilt Zoom (PTZ) cam that I could use to enjoy our building site remotely once the action starts.

Building site Cam

Our last house was full of random cameras as makers regularly sent me their kit to try out. This taught me one over-riding lesson though. get a single, appropriately integrated cam system with an NVR (Network video Recorder). like a lot of things in life, spending a bit a lot more indicates doing the job ideal (and once).

Now, while I wanted something decent, it still needed to be inexpensive too. You really can spend a scary amount of money on a good quality PTZ IP camera, easily getting into 4 figures. but that’s not in our budget, so I set about trying to find a a lot more reasonably priced solution.

I’ve previously had great success with an 8-camera Hikvision NVR setup in work. I’ve found it to be exceptional quality at an inexpensive price. This experience indicates i am familiar with their setup, including the browser, desktop and mobile apps so it made sense to stick with the same brand. I not only wanted a standalone cam for now, but also one I could re-use once the new house is built too, incorporating it into a multi-camera NVR setup.

In the end I went for this Hikvision DS-2DE4225IW-DE (catchy title). It’s a 2MP cam (1080p HD) with a 25x optical zoom that’s rated for indoor and outdoor use (IP66) and has an RRP of £400.50+VAT.

Mounting & Setup

The package included a power supply already wired to plug into the dome. but this would indicate having to run both power and data to the camera.

However, it supports the 30w PoE+ standard (802.3at) and so I gotten a PoE+ Injector to use instead. Power over Ethernet is fantastic as it indicates you don’t need to find an electrical supply at the camera. instead you send it along the same CAT5 (or better) cord that connects the cam to your network.

We’re currently living with family next door to our building site and this indicates we are in the lucky position to have access to super-fast FTTP Broadband. fast upstream bandwidth is a requirement for streaming high quality CCTV images. The property has a pole carrying TV aerials on the gable end of the house which is also in an ideal elevated location to monitor our building site next door. So I went with this DS-1602ZJ-POLE mount. There are a variety of other mounts available for this camera, including ones that fit on flat walls and in corners.

This pole does shake on stormy days though, which is particularly obvious when zoomed in, so that’s something you need to consider when working out how and where to mount it.

While it’s too early to draw any conclusions about the longevity of this camera, the metal construction seems strong and durable. Cameras supplied by authorised Hikvision resellers in the UK have a 3 year warranty.

There’s the option to hook up external microphones or speakers to this cam too, must you have a need for that. The list of whizzy sounding features also includes – large dynamic range (WDR), highlight/back light compensation (HLC/BLC), 3D digital noise reduction technology (3D DNR) and electronic image stabilisation (EIS). Phew.

Get a proper SD Card

The cam supports H.264 as well as the new H.265 video compression standard which uses a considerable saving on bandwidth and storage space. It can use a micro SD card for recording (if you’re not using an NVR) and can take up to a maximum size of 128GB.

I’ve seen pretty much every ‘normal’ SD card I’ve ever put into my other IP cameras fail. That’s particularly awkward if your cam is up a pole like this one.

So I’ve splurged on a Samsung 128 GB pro Endurance SD card which is created specifically for surveillance, security, dash and body cams. They are rated for up to 5 years of continuous recording so hopefully will supply trouble-free use until we get the NVR.

The rear panel of the dome comes off with 4 Philips screws to reveal the micro SD card slot – you can just make it out in this photo, below the bottom ideal corner of the PCB at the small orange ribbon cable.

Pan, Tilt, Zoom, Patrols, Presets, events & Alarms

Fixed cameras are the norm, and normally a better bet. but when you want to cover a large area with a single cam like this then a PTZ is ideal.

The 25x zoom is very impressive, not least at night when the camera’s built-in IR illumination can reach 100 metres. It’s part of the ‘DarkFighter’ range that uses ultra-low light technology to supply colour pictures down to just 0.05 lux, and black and white pictures down to 0.01 lux. It can go down to 0 lux at up to 100m with its built-in IR (as a guide, a full moon on a clear night is around 0.25 lux).

Here’s an example of me enjoying some rabbits at night which shows the incredible zoom as well as the low light capabilities built into the camera (click the image for larger version).

As well as the manual pan tilt and zoom functions the cam can be programmed with up to 8 different ‘patrols’ with each having up to 32 ‘presets’. The pan is continuous 360 degrees so there’s never a time where you have to go back the other way. remember to check out your local laws on domestic CCTV, privacy and data protection. Here’s some beneficial looking information for the UK.

Other smart features I’ve not even got into yet include the detection of motion, intrusion, line crossing and object removal.

Spiders webs across the lens were always a problem on the cameras at our last house, but so far the movement of the PTZ seems to keep them at bay on this one, which is another big advantage.

One thing worth mentioning is that there’s no dome covering the cam here, so you can see this one move. This indicates if you were using it for safety surveillance your subject would a lot of likely be able to work out when it was pointed at them.

Here’s another example shot, ideal at the end of the 25 times zoom checking out a bird table at the side of the house where we’re staying. I think this shot shows off the quality of the cam really well (click the image for full-size version).

Time Lapse

Like all good construction projects we are intending to capture some time-lapse shots of the build.

I’ve been experimenting with the ‘Event Scheduling’ settings for the camera. An interval of 5 mins (300,000ms) seems about ideal for this.

I am importing the photos into Lightroom and exporting the motion picture from the slideshow module which works great.

If you don’t have Lightroom there are plenty of stand alone apps available to turn a bunch of stills into a time lapse.

programvara

Hikvision cameras can be checked out in a browser or by means of dedicated apps for the PC, Mac, Android or iOS.

Recent updates to Safari have broken the ability to view the cam in a browser on the Mac, so I’m running the iVMS-4200 application instead. It works really well and supplies access to all the features of the cam remotely, whether checkingut eller konfigurera.

På iOS använder jag IVMS-4500-appen. Detta gör att du kan se CAM såväl som att styra PTZ manuellt och återkalla förinställningar också.

Vad händer om jag inte har någon kraft eller bredband?

Om din byggarbetsplats saknar någon av kraft, bredband eller båda, finns det fortfarande alternativ öppna för dig.

Om du har kraft men inget bredband (kanske bor på plats i en husvagn eller husbil) kan du fortfarande använda installationen ovan till ett Micro SD -kort, men utan förmågan att njuta av på distans över internet.

Om du har respektabel 3G- eller 4G LTE -täckning kan du använda samma system anslutet till en cellulär router. Specialister som Nucleus Networks tillverkar kvalitetsrutrar för detta ändamål.

Om du inte har någon kraft och inte behöver Ethernet, bara WiFi, kan du hacka ihop en MIFI -enhet med ett stort USB -batteri som kan ge dagar med internetåtkomst mellan avgifter.

Slutligen finns det allt-i-ett-alternativ tillgängliga som integrerar en kamera, batteri, solpanel och ett cellulärt modem som denna Reolink.

Summering

Vi har haft den här Hikvision PTZ -kameran installerad i cirka 2 månader nu och det har verkligen varit en lycka att använda.

Jag har inbäddat några provfilmer nedan från en YouTube -användare som ger dig en god uppfattning om dess flexibilitet. Medan vi har ställt in det här för att övervaka vår byggarbetsplats, skulle det naturligtvis vara fördelaktigt i dussintals andra applikationer.

Hikvision har blivit en så stor framgång genom att använda fantastiska funktioner till ett billigt pris. Jag har använt en hel del IP CCTV -kameror under åren, men den här saken blåser mig bort. Rekommenderad.
