Please note that taking these units apart will void your warranty

Taking apart these little guys is a very straightforward process. One simply has to remove two screws from the top back of the unit and then gently pry the front face plate off. When this is accomplished you get your first sight at the internals and the first inkling of how complex, yet well engineered, these “value oriented” IP cameras really are.

To remove the internals from the unit one simply has to pry out the whole subassembly from the plastic housing. This is a very easy and straight forward affair, just make sure to full depress the USB unmount button or you will have a very tough time getting the little sucker out!

All in all there are four printed circuit boards that work together to create the ICS-1013 camera. As we will see shortly these cameras may be listed by QNAP as being made by IPUX but in fact they are really made by Fitivision Technology Inc and are nothing more than rebadged Fitivision CS-1013 IP cameras. How to we know this, and more importantly how do we know this to be a verifiable fact? The answer is very easy, A) the MAC address of the 10/100 wired LAN decodes to “Fitivision Technology Inc” but more importantly the main controller chip on the main PCB is stamped as Fitivision FV1000. Who is IPUX and who is Fitivision? After doing some digging it appears they are the same company, with the exact same phone numbers and billing address.

As mentioned the controller chip for these IP cameras is the Fitivision FV1000. Not much is known about this chip besides the fact that it is an ARM9 RISC processor. In this camera this processor is paired with 8MB flash and 32MB RAM. Whether or not it is an ARM9 or the newer ARM9E does not really matter; either way it is more than powerful enough to handle the compression of video at 30fps that is required from this unit. More importantly than being powerful enough to handle the task it is responsible for, the ARM9 chips are extremely energy efficient and it is this combination of power and low energy requirement that makes them perfect for use in IP cameras.

The network interface chip is the IC Plus IP100A. This single chip is a full duplex of 10/100 Mbps Ethernet MAC chip that incorporates a 32-bit PCI with bus master support. This is certainly an energy efficient chip in that it natively supports several power down states, and even has the ability to issue a system "wake event" via reception of unique, user defined Ethernet frames (aka Wake On LAN event). In addition to all these great features, this little power house can even create a wake event in response to changes in the Ethernet link status. All in all this really is a good chip to have in a low power device where energy efficiency is a major concern.

The WiFi card adapter card is none other than the MSI MP54G mini PCI card. We got our first clue that it was the MSI as the MAC address of the IP camera when connected via Wifi decodes to MICRO-STAR INT'L CO.,LTD. MICRO-STAR INT'L is better known as MSI here in North America; and more importantly the serial number itself states it as “MP54Gxxx” just like all MSI cards do. To us if it walks like a duck, quacks like a duck and has a big old label on stating “I’m a DUCK!!” then we’ll take it at its word and call it a duck!

This mini PCI card is powered by the RALINK RT2561T which is a WLAN 802.11a/b/g controller chip. As stated this chip is capable of connecting wirelessly via 2.4GHz 802.11a, b or G but is not “pre N” or N capable. This means that while operating in 2.4GHz spectrum it can handle a data rate of up to 54Mbps while using 64/128 bit WEP; TKIP,WPA encryption.

The heart and soul of any IP camera has to be the actual camera lens itself. The sensor is ¼ inch CMOS sensor and this board type lens camera is capable of resolutions of up to 640 x 480 (aka VGA) at 30fps. It is also capable of QVGA (320 x 240) and QQVGA (160 x 120), both also at 30 frames per second. The aperture used on this camera lens is a F2.8 with a fixed focus length of 4.5mm and has diagonal viewing angle of 54 degrees.
In normal daylight operations it is capable of recording images in as little as 0.5LUX which is not much light at all(1 “foot candle” aka one lumen per square foot is roughly equal to 10.76 LUX)! As mentioned before and as you can easily see from the above photo, this camera board also has 6 IR LEDS for night vision mode.

The audio controller of the ICS 1013 is the Realtek Audio ALC203 which supports the Advanced AC'97 Rev 2.3 Audio CODEC. This controller chip is a 20-bit DAC and 18-bit ADC full-duplex AC ‘97 2.3 compatible stereo audio CODEC which incorporates proprietary converter technology to achieve a Signal to Noise Ratio greater than 100 dB. It also boasts an internal 14.318MHz to 24.576MHz PLL circuit that generates its own required timing signals, which in turn eliminates the need for external crystal and helps reduce overall electricity requirements. Even though the ICS 1013 only has mono speaker and microphone capabilities this chip is more than capable of handling multiple mono and/or stereo inputs and two pairs of stereo (or mono) outputs. Needless to say this little chip is certainly complete overkill for these camera’s needs but we love overkill.

As with most electrical devices, these cameras require electrical capacitors. In this case the capacitors are made by HER-MEI. While HER-MEI capacitors don’t have as bad a reputation as some, they are not in the same league as Rubycon to say the least. In the defense of HER-MEI they are an ISO 9001 and 14001 certified manufacturer that has been in business since 1995; and when you make as many electrical capacitors as they do you the law of large numbers is going to play a role in how many “bad caps” have your name on them. Let’s face it, no matter how strict your quality control is some capacitors are going to fail early. However, when big corporations like HP are willing to use a given brand you know that things can’t be all that bad.
To put things in perspective, these capacitors are going to be put under such a small strain that it shouldn’t really matter that much in the long run whether they are Teapo, HER-MEI, Rubycon or any other brand you can list. Of course if you feel strongly enough about seeing these in a product you own, you can always swap them out for higher quality ones fairly easily; as long as you are willing to void your warranty that is.
