With 4pcs 1080P Security IP Camera and 2TB Hard Drive Pre-installed,

I just screwed the cameras near an outlet (ran extension cord to one on the back deck), plugged my own hard drive into the hub, hooked it up to a monitor, and immediately had surveillance

I bought a NVR without a hard drive because I have an spare 1T 2.5 inch hard drive from my old laptop - that will save me about $50.

Daisy indicated that the 2 Terabyte hard drive in the NVR that I purchased would record up to 8 Channels/Cameras for 2 weeks automatically and then overwrite the disk starting from the oldest files

I installed a 1 terabyte hard drive in the NVR

BUT...the metal hard drive was dented so badly that the seam was split

I bought 8 channel wireless with 4 cameras and 2tb hard drive.

After purchasing hard drive installed that into NVR it did NOT work

Very easy set upGreat for price, Installation of Hard drive is super easy

This system supports 6 th hard drive

After installation of first Trend camera system I had to buy a hard drive to record.

So I just used one screw to install my 2.5 inch hard drive.

I purchased the Firstrend Camera System with 4 cameras and no hard drive

It takes 3.5 inch hard drives.

Instructions for hard drive could be more clearer, calling the 800 number and talking to the technicians was very helpful.

Turns out the hard drive just needed to be tightened a bit..

After I opened the NVR to install the hard drive, I found the 4 pre-drilled holes don't fit my 2.5 inch hard drive.

I would suggest make room for both 2.5" and 3.5" hard drives

Instructions are terrible, didnt come with HDMI cable or hard drive, so I called customer service, never got a response

but I was having issues with the play-back and how to access / set-up the recordings to the hard-drive
