Zmodo security systems are sold on Amazon. I recently was reviewing one of their systems just to see what the quality was like. The prices are very low which should be a tip off that the quality may not be there. The old adage, if something is too good to be true, then it probably is not.
Consider this system that Zmodo sells. The Zmodo PKD-DK4216-500GB H.264 Internet & 3G Phone Accessible 4-Channel DVR with 4 Night Vision Cameras and 500 GB HD. That’s a 4 Channel DVR with 4 cameras for $149 dollars. That is very very inexpensive. I see systems selling on Craigslist for $200 dollars that are Swann systems for just the DVR only for that price.
When I reviewed the Zmodo systems, I found that they received several complaints about the camera quality not being so good. Some users said that their cameras only worked for a short amount of time. If you are going to spend $150 dollars on a security system, then why not spend a few more dollars and get one that has some better quality. I see that the Swann systems and the Q-see systems do not have as many complaints as the Zmodo systems.
