Question: can you get replacement monitor and if not will the cameras connect to another system?
Document: Great picture on monitor day and night. Easy to hook up. Haven't tried recording yet, but neighbor does and he has same system. Also like the fact you can add extra cameras.
product came on time, no damage, I already had one set and wanted another. if you are looking for a good picture this is not for you but I get them for sound and it is fantastic for that. I know if anyone is near the cars or house and have run off several would be thieves because of it.
While i did not buy my system from Amazon I can tell you about the system and the customer support you get from Uniden. I am waiting for cords from Uniden. I got to use my system for 2 weeks between July and now. They keep telling me out of stock and giving me new dates the last one said they would be in the 15th of Oct and they would ship that day still no word so now they are telling me they will be in the first part of November.
And even then the actual images fail to show up. in this process the receiver also makes a strange ticking noise and the signal bars go from 5 to 0. I can't get a solid connection. The reception from the cameras and receiver are fine but the USB option is shot. I just sent Uniden an email letting them know of the situation.
This is a good quality system. Was fun to put together. The cameras seem rock solid. They instantly register with the receiver. For my purpose I use these for both surveillance and also being big into weather I'm able to watch weather conditions through out the day. One thing that bugs me. The image quality isn't best. The cameras are really sensitive to light so if there is anything reflective or emits light the cameras white out.
This is a great camera for a gas station or small store to make sure people are not steeling bubble gum, if that is what your goal is great.If you want to catch the thieves who is stealing your welcome mat while your away this is not the camera for you. They also make is sound like you can monitor your camera's any where in the world through the power of the internet, this is also not true. There is no access than any further that 150 feet from the camera's.
There is no automated system with this unit ,it will not record while your away and someone is taking your stuff, it will not take pictures while your away and someone is taking your stuff.
Three stars for being pretty good system. Downsides: the inside of the connector to the wires can come lose and need to be rewelded so handle it with gentleness so you don't have this problem happen (this happened to our cell phone as well). The other downside is that you can't record the sound (unless I just haven't figured this out). You also can't listen to the sound while it records on the computer.
Get answers 24/7 at our web sight,and that the bottom in normal letters not highlighted , to speak to someone human you have to wait regular business hours Central Time ,well that is not 24/7 again misleading.Well that about raps it up since I got these my car was broke into and my stereo ripped off ,G if only I had been monitoring my camera so I could take a blurry picture of them so I could waste the cops time .
This is the best buy for your money. I use it for security at my front gate and safety around my pool. I like the fact you can add up to 4 cameras.
Answer: the monitor is also your receiver. i assume it is replaceble, i have had mine over 2 years and it still works so have not had to replace anything. you cannot hook it up to another system unless is has the exact same frequency as the monitor/receiver as the one u wish to replace. the pic is not good but love the sound. got restraining orders on some nasty neighbors which was a blessing.
