DO NOT BUY LOREX. It might seem like a good deal with 15% discount, free shipping, and a 90 day no questions ask return policy. It is BS! I purchased a wireless security system from their website. When I installed everything, I lost my internet connections on my PC. I thought it was my internet provider. But as soon as I un installed everything, my internet started working again. So, I repacked everything, went online to return the system to Lorex. Needed an RMA number to return. Never got one. Went on their chat line three times. All they do is write up a ticket. After one month of trying to get an RMA number from Lorex, I filed a complaint with the Better Business Bureau. Lorex responded and give me the an RMA number and address to return the system. So, my advice to all is to file a complaint with the BBB if you need Lorex to respond. I will update when I get my refund back. Cross your fingers!Received refund 8/28. The whole return process started in early July. So, it took two months to finally get my refund.
