We searched for a good DIY home security system. We read several reviews and consumer report reviews and what other system were being compared to this one. So went choose this one. I'm so glad we did! For the price we received 16 cameras, the DVR box with the hard drive all wires, basically everything you need. The cameras are awesome! True crystal clear images day or night. The app works great! I would highly recommend this security system to anyone! You get a lot for your money, I can view when I'm away from home it's real time video is awesome. I have nothing but positive feelings for this system! It's everything advertised and much more! I'm really blown away with the quality with the images and system itself. All packed nice and securely. You will not regret your decision once you have purchased this and install it. The installation took about 2 hours (we had to run the wires in the attic) and then done!
