Home Surveillance DVR System with 4 Infrared Cameras at Harbor Freight

Harbor Freight Tools is offering a relatively inexpensive Home Surveillance DVR System with 4 Infrared Cameras.
The entire package sells for $249.99 with the coupon (good till 4/15/14) from their latest flyer. The flyers are available in their stores.
I have no experience with using this system, but in looking at other systems it seems to be a good price.
The web-link below shows a price of $299.99, but as I said above, with the coupon it is $249.99.
If you get one of these systems please let me know the quality of it.
