Question: Please give me the exact shipping weight, because this item arrived to miami, and after They sent me it to Ecuador. I need a maximun weight of 8,4 pou
Document: arrived as indicated. Set up was a snap. Hardest part is moving cameras into the best angles. The cameras are not tbe best but upgrading into high quality is easy enough. Software on dvr is straight forward and i thought was user friendly. I got the 4 camera model but had i known just how easy this diy project would be id have gone for the 8 camera system. Up and running two months with no problems. ****Edit***  It's been 9 months.
It didn't come with a hard drive so that's why I gave it a 4 on rating. Other than that it's ok
After reading several different reviews, I had a few questions regarding the device itself and decided to contact the company. I first tried the online chat and was given a rather lengthy SQL/PHP/Service unavailable message on the Live chat link from their home page. I next tried their phone support, where you give them your number and they call you.
After spending close to 90 minutes to get in touch with the company that is supposed to be a global leader in surveillance, I figured an invalid link from their home page, a non-working phone support system, and the URLs they give you on their hold music going to pages that don't exist...I'm going to say I'm nervous about investing money in a global surveillance leader's product.
Just received and installed. Cameras have narrow view, but work good in daylight. At night you will need to have a light  near by to get any decent video. I Was able to connect my windows computers, tablets and phones through LAN. I am still not getting remote access, appears to be because I have an airport extreme. This product is not Mac friendly (can view using IE, but not safari).
I would describe the directions as a brief overview of how to set it up. I recommend calling the company to help assist you to set it up correctly.In order to hook this system up to your computer, you will need to buy two Ethernet cables. One from your router to your computer and one from the router to the DVR. For you to use the mobile app you will at least have the router connected to the DVR with the Ethernet cable.
If you are installing your own hard drive it must be Sata, installation of hard drive was easy and directions were found in the owners manual. I will definitely be upgrading cameras over time to get wider views and audio. For the price I am satisfied. From what I can tell to get remote access you will need a DDNS name and server, which I am struggling to get working on my airport extreme.
they should let you know that this item does not include a hard drive and there are several issues with the software, but for the price you at least have a set of cameras
on the Turnpike for five years installing and servicing CCTV cameras, and equipment, and could not get this Zmodo model to come up on the App.Bottom line is I bought a paper weight. I replaced the junk with a CIB brand and got much better results and was online in a matter of minutes.Me personally, I would not recommend this brand or model.
Unit/cameras still going strong through all weather conditions from snow to 95 degrees. Need light at night for decent vid but wasn't a problem getting motion lights installed on outside sources for an easy diy project for pennies. Well worth the $$$ so far.
Answer: As mentioned in the Amazon details, it's 15 pounds... It includes 4 cameras, lots of cabling, and the DVR box, plus all the packaging.  You're unlikely to find a system that lightweight... If that's an absolute requirement, try maybe finding the DVR with no cameras and ordering them seperate.
