On 12/2/14 I ordered a Zmodo ZM-BBY4-1T 8 channel 960H digital video recorder with 4 x 700 tvl cameras and Pre-installed 1 TB hard drive from Frys online. Today 12/4/14 I received the security system by UPS. I opened the box and to my surprise the camera were only 600 tvl lines. I already had 6oo tvl cameras and wanted to upgrade. What a let down. I called Frys.com and had to wait 23 minutes before speaking to a live person. I was told they did not have any of the 700 tvl cameras to replace for the right product, They said I could send the product back fot a refund. This was a BAIT and SWITCH from the get go.
