Aldi Wireless Cam

Mr.Success

A neighbour gave me a wireless cctv camera to try out in the calving shed. Its approx 85 meters from house. The leaflet says it has a 100 mtr range.

There is only 2 trees blocking the line of sight but still the footage is very bad. You cant see anything most of the time and its just grey fuzziness.

Why is this, the leaflet said it would even allow for an external wall?

Can you try it out at much shorter range eliminating the trees? Say a garage or the like.

I had the same problem. 100 metres clear line of sight.

I had to put a signal sender in the middle... Camera transmits signal to the camera reciever.. reciver is connected with a scart lead to the TV signal sender,, Tv Signal sender recives image and is connected to the telly.

Bit of messing with the channels on the camera and TV signal senders, but it works grand. They are under a bucket on a wall for three years now! Oh yeah, need to bring power out also.

Other thing I did was to buy a cheap 2.4 ghz ariel with the correct connecter and I put the camera ariel outdside the shed. I don't know if you can do that.

Job done. This allowed me to go around the line of sight obstructions and stay in bed a night!

What is the lighting like? A lot of those cameras need very good light.

Trees block signal more than most walls! Trees contain alot of water. Water blocks radio signal better than most walls do. Signal will get worse when leaves appear on trees (more water contained in trees with leaves).

I have this aerial haning from a RSJ on the wall, just run the cable into the camera.

Just check if you have a male or female connector on the camera.

This one has a bit more gain. but be careful too much gain can screw up wifi signals etc.

Has any of you a recommendation for a product you could use before the video sender to take input from say 2-3 cameras and send it in one feed?

"dbi" is a useless measure of gain, and most aerial manufacturers use it for sales, "d Bd" will give give you true readings

also at 2.4 Ghz useless you use top quality coax cable you will have serious losses

If you want multiple cameras, probably better to use IP Cameras and a Wireless Access Point/Router instead of video senders.
link foscam ip Camera:

or else a Complete system.
link wireless camera server:

Of coarse at the end of the day you won't beat a wired system for reliability.

Hello SnowMan,
Don't care if Dbi is meaninless. It's working..my ould man had a ringside seat on a C-Section on Monday from the kitchen.

I have this system up and going and I have a perfectly acceptable picute as good as TV reception on the analog (since I cleaned the camera lens). Range of about 70 metres with the signal sender in between to get around sheds in the way.

THe camera -TV reciever can take four channels and I have two camera on a 8 second changeover time. So it works grand.

My next step is an IP camera to be able to check in from work, and to put a remote camera up the land so I can see the back of the farm that is the other side of a hill.
