Very quality products, sales & technical support support
I have bought 3 Nvrs for my houses. 1 is a NR9163 4K 16 CHANNEL ULTRA HD. And the other is a N882A63B 4K 16 CHANNEL ULTRA HD. The one on my main acreage is a N882A38B-W 4K 32 CHANNEL with a POE÷ SWITCH. I view it on a 32" Samsung 4k monitor or on my 55" 4k tv. I also purchased the 4K E881AP-W PTZ CAMERA. It is well worth spending the money. I have all Lorex cameras from zoom to PTZ, person vehicle detection most with audio and some with 2 way audio, active deterrence. Some are just video only. Most are 4K 8 megapixel 30fps and some are 2K 5 megapixel15 fps, and have no skipping or stuttering of movement. All cameras are nocturnal with color night vision. With low light and a couple setting adjustments you'll have surpurb color video at night. I purchased the professional grade NVRS directly from Lorex store. You can purchase wherever but be sure to fill out warranty on Lorex site. When I've had to call technical support for not thinking enough and said bought from them directly. They look you up and always get correct help and very courteous employees, if looking for a great product go to lorextechnology.com or call their sales staff and they will help you purchase what you need for your camera protection or call 1-888-425-6739. They also have very fast delivery and care slots about packaging well for the brutal delivery services.
