Hello, I'm new to the site and CCTV. I have just purchased a Swann DVR4-4400 with two cameras plus i purchased 1 extra camera. Problem 1- I purchased a standalone outdoor microphone from Maplin UK wich connects via the camera power cord splitter and plugged audio phono into back of DVR. Sound was fine but after a short while it seems to die, it hum's a little then crackles and dies. If i try again later it will work again for a short while...What could be happening?Problem 2- It has 720P resolution but only offers 4 days continuous recording unless i lower resolution to 960H then i would get the 30 days i was promised by the salesman! (feel a bit miss led). Anyway, When i lower the resolution to 960H and it reboots it then suffers video loss and i can't seem to get it to work on 960H if i require 30+ recording, It will only work when i put it back to 720P, Any ideas what i may be doing wrong?, cheers.

If I set DIP switch 2 to 'on' and wire up a simple phono cable to the SPKR and GND terminals I can link the Agility 3 panel up to the line-in on my Sonos AMP nearby. This allows the voice notifications and beeps to be played through a selected Sonos zone in the house (or group of them) which is lovely as my main Agility panel is in the loft far away from the front door. However if DIP switch 2 is 'on' and DIP switch 3 is 'off' I get a panel tamper alarm going off. This isn't discussed in the engineer manual so I'm wondering if there's some standard procedure i've missed regarding storing new DIP switch positions before power cycling or something ? Or is there something i need to do with the remaining external audio terminals? I couldn't see an official Risco device that connects up to all these terminals either - does one exist ?
