Question: Can this do just a 2 channel side by side split, or is it only 4 channels?
Document: I have a 4 channel DVR, but I've been wanting to add more cameras since there were still some areas that weren't covered, like our backdoor and shed. Since I had the DVR channels maxed out, I couldn't add any more cameras, and I didn't want to spend a couple hundred more dollars on a new 8 channel DVR.
I purchased this as an inexpensive way to add additional cameras to my 4 channel DVR. It worked well and was fairly east to set up. After about 2 months the picture became distorted. I contacted the company and returned the unit. They promptly determined it was a bad unit and shipped me out a new one. I am not happy it broke but was happy with the customer service of Evertech.
I'm using this unit with 4 cameras, a Koolertron 7 Inch HD FPV Monitor for off road and 4x4 travel.the good:* easy to use - individual buttons on box and remote control selects picture in picture, quad display, or pick any of 4 cameras individually. * standard bnc connections that most home security systems use. * has 2 bnc outputs (identical signal) one for monitor one for video recording.
It is not user friendly. Programing it is difficult at best. It has to be reprogramed after every power glitch. On 2/13/2014 the unit has completely stop working. That's only five months! I now give it one star.
I'm going to try unsolder it and raise it up.Even with all those bad points, I'm still giving it 4 stars because it works as advertised and was inexpensive.
This quad splitter worked, as advertised. It runs 24hrs a day and I'm quite satisfied. Resolution isn't HD, but to get that level of resolution you'd have to pay 5 or 6 times the cost. For a low cost splitter, I would highly recommend this product.
Recieved wrong product. Very first two orders screwed up! Not happy camper! Will have to use someone else to purchase products. Too bad!
Qaud work great. .good buy..thank you amazon
Great speed and product.
* surface mounted chips are machine soldered and look good, all other electronic parts (the stuff that rises above the board) are poorly soldered as are the bnc connectors, I re-soldered all of them and because I'm using this off road I'm using electronics grade RTV to stabilize all those components so they don't vibrate. * menus, besides basic monitor selection, is a bit painful to scroll through. * built-in battery is soldered to the board.
Answer: Yes it can do a 2 channels split side by side ,pic n pic,this Quad is nice,zoom,the work.i recommend buy ing it.
