Question: is the power 110 or 220?and do i have to place camera and receiver infornt of each other for better results?
Document: I either have to reset the power to the receiver or the camera to have the picture back. Gawd... it's really painful. Then again, I can't afford to run wires throughout the house for fixed cable cameras... I really hope we'll have better technology to deal with this kind of issue. It's year 2013 already.Downgrade to 3-stars.
The cameras work OK, but i only recommend these cameras if you have clear lines of sight to where you will place your receiver, probably something hard to do if you're installing more than one. mine that are only about 20' away lose connection all the time, seemingly every time the wind blows.also remember that you still need a cable for power, and there's a cable that will hang from it to 'pair' it to the receiver.
I had to power-cyle the camera or hit the reset button below it's rear antenna stub. Yes, it's very hard to see since it's the same plastic and same color like the camera itself. Just put your finger there and feel it - then press the darn thing. :D It's easier for me to just unplug the power cord from the wall socket and reset it. This defeats the purpose of a security camera as it has un-controllable outage.So I have one camera that shows better functionality.
Better than expected. Image is pretty clear in daylight. Image OK (not great) with IR turned on. Extremely simple to install. No drilling or attic work required. I use this camera to augment my wired cameras. Note that a power source outlet is needed either indoors or outdoors to operate the camera. The receiving antenna also needs a power source. The antenna output either plugs directly into the video in on your television or goes into an open channel on a DVR.
It would disconnect and reconnect itself when needed. All it needs is just some adjustments raising or lowering etc to get better signal. And it's working good so far.LONG-TERM UPDATE 01/28/2013:The posted issue as I've seen above is aggravating and it happened to BOTH cameras I have. The camera or receiver would not produce a picture (don't know which but had to reset both to make sure). Just a black screen is shown once after every few days/weeks.
This camera is okay for the price. It is very easy to setup. Just plug in the power on the camera and the receiver. That's about it.
Everything came packaged nicely and the instructions were very well laid out and easy to understand. I had no trouble whatsoever connecting the power cords to both the camera and wireless receiver, and the video cable from the receiver to the RCA video input jack of my television.
Overall this camera is very user friendly. Being wireless, it was very simple to set up - plug in the camera power, plug in the receiver and hook up your video.Just in case there's any doubt, this is a security cam so there is NO SOUND.There are two settings - a low res/high refresh (320x240 30FPS.
The lorex LW2110 Wireless Digital Security Camera is a user friendly security camera. Setup is relatively easy with the only problem is being able to power the camera in a remote location. There are 2 settings for viewing, a 640 x 480, 12fps mode and a more smooth, 320x240, 30 fps mode which is controlled via a button on the receiver.
It works well but the signal drops about once every couple of months which requires turning either the camera or receiver off and on to regain connection. I'm not sure if this is because of electrical fluctuations or just interference. I have made this occasional hassle easier to correct by connecting z-wave controlled switches on the power plugs so that these can be switched anytime there's a video problem even when not at home.
Answer: Power is 110.  As for in front of each other, to my knowledge they don't have a front and rear except the camera and naturally it would have to be aimed where you would want to be able to see the area.  The antenna pick the signal up and they are 360 degree in any direction.
