1. Power cable
That issue will resolve itself as you give up and go with something that works. I've seen clients want this or that and we have to give them time to process what is available or what it costs to hide wiring or install another outlet. After they get through that then the work can begin.
2. Memory card use.
As to the memory card those are a 20 buck item and sharing it with other device is a BAD IDEA. Install it and let it be. If you want to create more support, sure, take it without complaining later.
As to bigger memory why didn't you go with some HDD recorder. Here the wired camera 500GB with cameras are cheap as exampled at http://deals.woot.com/deals/details/05f48227-f0b9-4373-bcfc-e458499bb9c1/zmodo-4-ch-cctv-security-dvr-outdoor-ir-camera-system-500gb-hd-network-view (190 bucks) Your system was 415 so plenty left over for a display or just watch it from the network.
3. 2.4GHz links.
Be sure you can return those wireless CCTV systems. If you've seen what I see you know that they are subject to interference as well as interfering with a lot of WiFi systems (in spite of claims to the contrary.)
4. Other systems.
If I wanted to setup something new I'd look at DropCam again.
And keep shopping. - New!

Ive got a 3 year old and a new born. I did get a baby monitor for my first child, but it was too much hassle taking the monitor everywhere I went with the baby, epecially when you need two hands to hold the baby and then have one hand holding a bottle. So I just ended up not using it. Ideally I needed a few baby monitors but all going to one to receiver, so I can put one in each room. I then came across Maplins and BnQ and saw a wirelsss CCTV camera but its too expensive, 2 wireless cameras with 1 monitor was like £280. I then search the net and tradexguru . com and found this one seen in this cctv kit titled " Etronic Outdoor Digital Wireless signal 4 x CCTV camera Surveilleance System with SD card REcord DVR and 7 inch LCD screen.
For cheaper and with all 4 cameras and picked it up locally instead of getting it sent from Hong Kong. So I am trilled to bits. I brought it and it seems to working well. But it comes with a wall plug but one of the cable is a bit to short to where I want to put it. I spoken to the shop and they suggested buying a normal wall extention cable. But I dont like them, becausae they are big and I want the cable to be as thin as possible. Does anyone have any suggestions?
Also the SD card takes 32GB. I dont use all of it, as I normally have it on montion dection to record when we are out. But Im thinking of taking it on holiday with me when we go to Spain this summer, and was wondering if anyone have got something like this and have added extra memory device to record for longer? If so please let me know how.
P.s Please do not send me installers contact details as I want to keep cost as minimum as possible and do it myself if I can.
