I bought the camera (Exview C515SG Sony Effio Exview HAD II 700TVL 2.8~12 mm Varifocal Lens 60m IR Camera.) about 4 months ago now and it has give no trouble at all since. In fact, it is the best camera that I have purchased to date. The zoom and focus controls are covered by water resistant caps - with 'o' rings to ensure water does not get in. The lense is top quality, sharp to the corners at either full zoom or wide angle. The lense is not one of these 'f2' cheaper type lenses, but an excellent 'c'/cs' type lense - probably in the region of 'f1.4'. This f1.4 lense gives a much brighter field of view, and with the bigger diameter lenses gives higher resolution images. I have the camera set at wide angle, and the picture is sharp even to the edges - this is important as people try to creep up to the side of cameras so as not to be seen! The CCD sensor is also very sensitive, staying in full colour mode when all the other local security camera i/r illuminators in the area have come on and they have turned to b/w mode. When the ambient light has fallen to a certain low level, the camera then suddenly switches to b/w mode. Most cameras lose colour right up to when they become b/w, but this one maintains full colour right up to the optimum end. When setting up the camera, I find it easier to stand where the camera needs to be looking, then focus in that part of the wall where the camera needs to be mounted. You can adjust the angle of view from a similar distance from where it will be looking from the ground. This procedure will give a good indication of what you want the camera to do before going up the ladder! The camera is relatively easy to to fix and adjust into position. The camera is mounted on an arm with three 'knuckles' for adjustment. This is very important as this ensures that the camera can stay 'level' with the area under view - you can't do this with most two 'knuckle mount arms... Securing each 'knuckle', is done with an M3 Allen wrench. This can be a bit fiddly, but it is well worth it once it is done. The arm is secured via a large round 'foot' to where ever you are mounting it to. When the camera is set up, just sit back and watch in high 700tvl resolution. An excellent camera.
