I can? say enough good things about these guys! They respond quickly to questions and they back up their products. I recently purchased a Samsung DVR from them, but it was defective from the factory. It was a quick no-hassle exchange and they got me back up and running in no time. I will definitely be shopping here more!

I have not hooked it up yet as this is new construction and you cannot have electronics in a building before the drywall goes up, but it was easy to select and arrived on time and when we asked for help to see if we could use RG6, they were helpful. What is not to like about S-V.com :)

I found Surveillance Videos sales staff to be extremely knowledgeable and helpful, and their price-matching guarantee is excellent. They even matched a competitor? price that was nearly 30% below their normal price. I will use them from now on when I need security cameras and related hardware.

I enjoy the ease of shopping and ordering online, and with surveillance-video.com, all of my orders were exact and prompt. I almost feel hesitant to rate somebody so good for fear of being crowded out by other buyers; I would like to keep them for myself if I could. Thanks

Great prices, quick shipment and delivery! Just made the purchase for a PC based home security system and has not dealt with customer service, but everything from this merchant is exceptional. I will buy from this company again!

Excellent technical customer support to help me pick the appropriate equipment. Excellent working software; works as advertised!!! (Which is not usual in the software industry, especially when hardware integration occurs)?

Top quality service and customer support is what I like the most about this company. It doesn? matter how good the deal or the merchandise is if the service is not there when you need it. I had a small problem with one of my cameras and they took care of it promptly with no hassle.

I purchased a couple of wireless cameras online and was pleased with the ease of ordering. I received an email immediately notifying me of the exact amount being charged to my credit card, how, and when they would be delivered. I definitely will shop here again.

Very pleased with Surveillance Video purchase and follow up. The digital recorder arrived with a failed hard drive. Called customer service, and was immediately told a new unit would ship that day. The new unit arrived the next day and UPS took the old one back. That? what I call customer service. These guys get an all around A+. Thank you Surveillance...

John, San Francisco, CA

Product was exactly as advertised and 1/2 the price of what I paid just two weeks before from a local merchant. Product shipped same day as ordered and arrived 2 days later. Great seller and great service!
