TRENDNET AND D-LINK IP CAMERAS

 


IP-enabled cameras are neat little gadgets which let us keep an eye on what's important to us, no matter where we are.  From watching babysitters, our driveway, front door, pets, or even favorite plant, IP cameras provide us security with the click of a mouse.  Today, we will look at three cameras - one from Trendnet, and two units from D-Link.

First, let us look at the Trendnet TV-IP422W:

In the retail package, we have the camera, antenna, documentation, power adapter, CAT5 cable, and mounting plate / bracket



Here we see the camera itself.  Note the IR emitters around the lens.  These serve to illuminate the area when in total darkness



The rear of the camera shows all the connectors.  We see the Ethernet port, GPIO pins, WiFi antenna, 12VDC input, and audio output. 
Note that the camera has WiFi, allowing you to place it just about anywhere you have an AC outlet and a signal.  As for the audio output, it is not amplified.



On the side of the camera is a USB port which can be used to save video to a USB storage device.  Very cool!



The web interface of the Trendnet is pretty straightforward.  MPEG4 compression delivers smoother video than MJPEG.  The directional arrows move the camera on its axes.  Clicking on the image centers the camera on to that point.  The numbers on the left are presets where the user can predefine points where the camera should be facing.  The TALK  and LISTEN buttons allow the user to communicate to the viewing area using the built-in mic and audio output.  TRIGGER OUT can be used to enable other external devices through the GPIO pins.  Recording and snapshot functions are pretty typical, and quality is as good as the streaming video itself.  But perhaps the cool part of this product is the NIGHTMODE, where the IR LEDs will let you see in complete darkness.  Such is a very important feature for security cameras, or kiddie cams - where you don't want to wake the baby with bright lights.  Furthermore, you can also open ports on your router to be able to not only access this very same browser interface, but also watch just the streaming video via RTSP.  If your mobile phone supports QuickTime, then you can open your WAN address and port on your phone's browser and watch the IP cam video. 

In our testing, the camera worked as advertised and had no problems connecting to our access point with WPA2/AES security.  Video quality is exceptional as shown in the image, and we were able to get near 30fps video frame rate over LAN, and around 15-20 fps over broadband WAN.  Audio sounded excellent and clear.  We also requested that a colleague 8000 miles away connect to the camera over WAN and carry a conversation with someone while watching their video.  Although not perfect, it worked flawlessly although with a 1-2 second delay.  The only missing feature from the IP-422W is optical zoom - its 3x digital zoom really doesn't do much other than make small pixels into bigger pixels without increasing detail.  As for streaming via RTSP, we had trouble getting it to work with a couple phones, but that is more the fault of the CODEC and software support on the phone's browser.  Using a PC to view the RTSP stream over a cellular WAN link worked flawlessly as well.

 

 

Next, let us take a look at the D-Link DCS-5610.  This little unit is not wireless but does have one advantage over the Trendnet - it has 2.6x optical zoom!


Aside from the camera, a LAN cable, power adapter, CD, documentation, and mounting plate are included

Behind, we have the DC power input, RJ45 with PoE support, mic input, GPIO pins, audio output, and a mic switch


Unlike the Trendnet, the DCS-5610 has its mic move with the lens


The D-Link web interface is similar to the Trendnet, but also allows you to define the PTZ speeds.


At the full 2.6X optical zoom, we see more details in the painting

The DCS-5610 perform admirably well but its lack of WiFi made it difficult to position in certain places.  On the other hand, its support for PoE negates the requirement of a nearby power outlet.  This product is clearly designed for businesses.  Image quality is very good, but the video is not as smooth as the Trendnet.  Also, it lacks the IR emitters which allow the Trendnet to see in the dark.  RTSP and WAN access work well as long as the requisite ports are opened on your router and firewall.  Overall, it does what its supposed to do, but its a bit underwhelming.

 

And so we move on to our last contestant, D-Link's top-of-the-line DCS-6620G.  This beauty features 10X zoom, remote control, and WiFi, but sadly no IR illumination either. 


Along with a nice retail box, the DCS-6620G comes with a power adapter, remote control, AV cables, Ethernet cable, mounting bracket, and documentation


Here we have the antenna connectors, DC input, mic input, GPIO pins, and AV output


A credit card-sized remote control is also included, allowing you to control the camera without the web interface

Here is the GUI of the DCS-6620G.  Pretty much the same as the DCS-5610.  The camera is at 1X zoom.


Now, we are at 10X zoom.


10X zoom with 2X digital zoom


10X zoom with 10X digital zoom

The DCS-6620G is a fabulous device!  10X zoom, remote control, and all the other bells and whistles, except for IR night vision.  Video is not as big or as smooth as the Trendnet either, but still very usable.  Audio streaming worked well, and the PTZ controls were easy and intuitive.  Overall, this edges out the Trendnet TV-IP422W simply because of additional hardware features.  You can add IR LEDs to DCS-6620G, but you can't add a 10X optical zoom to the Trendnet!
