Dropcam Echo : Home Security Meets the Cloud

Power:
It is essential for the Dropcam to be always connected to a power outlet. However, this doesn't mean that the unit is a power hog. On the contrary, measurements with a Kill-a-Watt meter over a usage period of 28 hours indicated that the power consumption is approximately 1.4 Watts. Though the unit did get warmed up after extended usage, it never became hot enough for us to get concerned.
Bandwidth:
Another issue of concern for consumers would be the bandwidth consumed by the camera. With tiered broadband plans in place across the country, it is essential that users be aware of the amount of traffic generated by the camera. As mentioned in an earlier section, the video bitrate is around 80 kbps and the audio bitrate is around 60 kbps. One minute of video streaming consumes approximately 1 MB of bandwidth. This means that a Dropcam running 24x7 would, on an average, eat away 45 GB of the monthly quota provided by the ISP.
Latency:
Latency is a very important measure for IP cameras. A cloud based approach has some disadvantages in this respect, since high load on the servers and CDN issues may lead to lagging video. These are in addition to the local network conditions at the site of the camera as well as the viewing place. In our evaluation of the Dropcam Echo, we saw less than 1 second of latency on a T1 line. With the iPhone (AT&T's 3G service), it was 4 seconds, while my cable connection at home gave a lag of 11 seconds on an average. All these go to indicate that, at present, any latency issues are because of local network conditions, and not due to overloaded Dropcam servers. Hopefully, the Dropcam servers should be able to scale well with an increase in the number of connected Dropcams.
Consumers may look for better optics, PTZ functionality, wider viewing angles and other features in the camera, but the Dropcam Echo is fundamentally limited by the features of the Axis camera. The choice of the brand, as well as the model, is probably dictated by the manufacturer's willingness to let customers develop their own custom firmware on top of the base hardware platform.
At first glance, the Dropcam appears overpriced at $279 for the features provided. When the cost of the Axis camera is taken into account, we realize that Dropcam's excellent software stack and cloud service almost comes in for free. From a price to performance ratio, there is no doubt that the Dropcam Echo comes out to be a winner.

Very interesting product, yet one caveat:your security system relies on Internet being up; If you go on vacation and switch off the mains, you won't have either current for the cam, nor for Internet.
in europe, several companies are trying to lure small business into setting up IP surveillance cameras, intrusion detection and transmission onto a smartphone (on demand only, in order not to burst the data traffic cap). IP camera like the Axis) have both intrusion detection software onboard and a hardware current loop switch (which could be used for intrusion detector).
the largest issue with video surveillance as i see it: (on my remote screen ;-)) is the lack of support for the megapixel cameras such as the Axis 207MW which have been around for a decent price for some time now.
I highly suspect an artificial restriction by manufacturer of NAS on entry-level systems
I have setup a surveillance DVR 24/7 with a Qnap 219 and 2 * Axis 207MW with few issues except that the QNAP F/W for that hardware does not allow the use of the camera in megapixel res: i am stuck with 15fps 640*480 AVI recording
Yet, using curl, I was able to reach 10 fps at 1280*960 in JPG mode directly from the linux shell.
I am looking seriously into switching to synology because of their more honest way to handle additionnal camera through licenses

Sounds like they have a good start, but I wonder if this model will be sustainable in the future. If a user installed more than one of these, or if/when they produce HD models, the bandwidth usage could quickly get out of hand for tiered access plans. Perhaps for a more extensive home installation they could offer some type of a base station, either a USB device or some type of nettop, that could handle the recording functionality of local cameras. This device could integrate its own access point, so that setting up individual cameras would be as easy as plugging in over USB or ethernet for an initial setup, then putting them on location. They could also then make the mobile app location aware, so that video would only be streamed to their servers when the primary phone was away from home, or on request. Then all other video, such as when they are sleeping and not watching their phone, can be stored locally and not take up bandwidth.rcc - Thursday, August 12, 2010 - link
The camera itself handles motion detection very differently. If set to motion detection the camera doesn't output data at all, until you have a motion event. Sounds like this is one of the features they disablled so they could charge you for continual recording.One of the advantages of IP cameras in general, and one of the things that makes them a bit more expensive that Analog cameras, is that there is a fair amount of intelligence built into the cameras for functions like this.
Axis makes many decent IP cameras, this one is near the bottom of their line, as expected given the price point that people will want.
Since drop cam is not making the camera, I think they should concentrate on the "cloud" end of things, and setup, and let the consumer pick from a range of cameras.

Cut power & internet connection; if possible from a street service panel accessible to anyone with a large cutter.Rick83 - Wednesday, August 11, 2010 - link
And wake everyone who has a UPS in the entire block?Because figuring out which internet connection goes where isn't that easy.
And I expect the same for electricity.
And then you have to hope that there isn't a backup battery and backup wireless internet connection....
Probably not worth the hassle for a quick enter and grab....

But since it operates on wifi, and wifi is a very select range of frequencies usually 2.4 ghz or 5 ghz and sometimes 3.6 ghz, wouldn't it be possible to "overload" those bands in a short range with something that produces enough frequency noise.Thus anything that isn't using cables won't be able to communicate. Doesn't matter if the ip cameras are storing there info locally or to the cloud, if you can't talk to the router than the effectively can't communicate.

This was on one of those CSI episodes where they jammed the signal. WiFi jammers do exists like any other wireless signal blocking.http://www.chinavasion.com/product_info.php/pName/...

As I recall, that camera also has an Ethernet port, and works off POE if Dropcam supports it.Hook up the POE switch, router, and modem to a decent UPS and you are ready to go through basic power outages. If you are really concerned about someone cutting your Internet connection, Talk to one of the companies that provides video over 3G cell phone networks. Pretty pricey tho.

Would something like this even be valid evidence? Even if you had this camera running and recording an area where something was swiped, assuming the criminal took basic precautions such as covering their face and any other distinguishing marks all you would get from a VGA video is a basic idea of their size. Anything that is going to help bring a criminal to justice is going to come from more traditional investigation.I would imagine the use of this is more as a nannycam, or for example if holes are being dug in your yard and you want to see if it is the neighbor's dog, or a situation like the author described.

Look at the bright side. Reviewing the footage (byteage?) would show the forensics guys where to look for more evidence.
