Question: Can we record on all 8 channels at once on the 8-channel model?  Or just 4 channels?  The description, combined with reviews have me confused...
Document: Excellent for home security. Has really put a damper on the 15 year old lying to me about ditching school and bringing friends home when I'm not there. Again this is not a $1500 dollar system so some low rated reviews seem unwarranted to me. Did have two of the cameras DOA but warranty took care of that. It's not like I really needed all 8 cameras going right away.
This is a great system I have not had any issues with it at all, I've used SWANN tech support to set up my remote access and email notifications, they are some of the best customer service I've ever dealt with. I have all 8 of these cameras up and running and always set to record. The video quality is good but if you want amazing or will need higher TV line cameras.
So, if you are actually scanning for an event you have to scan 4 channels, then scan again on the other 4 channels.Why TruBlue?I thought for sure the system would have blue LED infrared like some of the newer CCTV system. But it has the red ones. Why is it called TruBlue? I guess because of the blue light on the DVR around the control panel that you will never use because it comes with a mouse. What a joke!!
According to the comments left by others, I must have gotten the runt of the litter. These cameras were install on the outside of my house. Of the 6 cameras I installed, the motion detector function for 4 of them did not function properly. They would record when a car drove by in the street in front of my house, but would not record something as simple as someone walking up the sidewalk to my front door.I contacted customer service easy enough.
I read all the great reviews so I bought it. Installing wasn't too hard, just running the wires and drilling holes in exterior walls. Then I called the 800 number to help me set it up. Set up works for here at home but I've called 4 times and I still can't get it to connect remotely on my iphone. On my last call the woman said that it works according to her computer so it must be a bad 3g connection, then hung up.
I bought this DVR bundle to replace my old 4 Channel Night owel DVR , the price was good but I was really disappointed with the camera's image quality , my old 480TVL cameras quality are much better & the Night vision was much clearer compared to the bundles Swann cameras , also the DVR its self crashed couple of times when I was setting it up but now it's working fine but I still miss my old 480 TVL cameras quality.
If you aRead have one set up save the settings and just enter themI went from a 4 to a 8, 4 isn't enough. Anyway, there are online set up guides better than the one they give you... Or just call tech support... They can be allowed access to your computer and do the set up for you.
This alone is nearly worth the price of the entire system.- The 60' cables are longer than you think!- The image is good. We can easily ID anyone on our front porch from about 10' away.- If you have an iPad / tablet, you get to perpetually walk around the house with a 4- or 8- camera screen of your entire system feed. It is AWESOME.
Okay is now the 15th of July, I have returned 4 of 8 cameras and they have not even acknowledged they received them and now you cannot get a hold of a person at their customer service number.....they say they will call you back........I guess I will just return the whole security system as it does not work for me with only 4 cameras......I don't understand why AMAZON does business with a company like this
Got this unit from amazon. Installed all 8 cameras around my home. Everything worked for about a week, then 4 of the cameras quit working. Swapped non-working to working cables and no go. Then noticed a ring around the camera eye, smelled it and it smells like burnt wires. SO now have 4 working cameras. A couple days later another camera quit. Same thing, burned smell on camera.
Answer: Yes - 8 channels permit recording all at once.
