SOURCE: Problem

it isnt the infra red.

on you dvr machine there should be settings or settings on the camera for mirror and flip.

these are features on better cameras and are normally on the camera body, but veiwable on the cctv monitor. they should be menu driven.

I hope this will be of help

Test you remote


Ever wondered if your radio / TV / Receiver / DVD remote is still working? You've changed the batteries and still it does not seem to operate. Test it like this : Using your digital camera or cellphone camera point the infra red LED of the remote into the camera as if to take a picture of the remote like this:

Operate one of the buttons on the remote and watch the remote through the viewer and you should see this:
/uploads/howto/2_26_2012_10_24_55_am.jpg

The LED will be flashing rapidly if the remote is functioning. This is because the infra red signal sent by the LED is not visible to the naked eye but is to the camera's circuitry. Magic!! Now go try it. You know you want to. ;-) ps This will not work on your vehicles remote fob as it works with radio signals and not infra red light.

Why does my Defender camera, model 26001, not function in color nor does the infra red work?


First check the power supply, make sure you are over 12vdc or 24vac depending on your source with all cameras connected. Try only one camera connected to the power supply. Make sure you have the positive and negative connected correctly. If the power is good the cameras may be bad.

Remote does not respond to any function, tv is on and cannot change chanel or anything, frozen


you need to check the battery contact with the battery terminal make sure that the terminal is clean.

check open the cover of your remote and check the solder of the battery terminal from the pcb board use a soldering iron resolder it.

using your cellphone camera test the infra red emmision of your remote control aim the camera to the infra red of your remote.you must see at the screen of the camera that the infra red is lit when any button is pressed..if not the infra red is busted.

using your cellphone camera again to test the infra red emmision of your TV. Aim the camera to the infra red of your TV.you must see at the screen of the camera that the infra red is illuminating.if not the infra red sensor of the TV is busted.

Samsung CXM1374 TV/VCR COMBO. The original rmote no longer functions. Changed batteries but still no functions work. Does remote or TV buttons have to be activated to reprogram?


you need to open the cover of your remote control..visually inspect the PCB for any loose connections/cracked board specially the battery terminals...solder any loose connections and if nothing happens replace the crystal oscillator from the remote control it is a square,color orange sometimes blue with a label on it its clock speed in MHZ. it is available at electronics supply store..you can use the camera of your cellphone to test whether the remote is working by just pointing the camera to the LED at the top of your remote once you press a button from the remote the LED should lit...means your emote is working...3rd test the LED/infra red if it is not busted..remove the LED INFRA RED from the pcb and using a multitester analog supply.set the tester to X1 range then supply the terminals positive negative with the test probe there should be a continuity connection and the LED should be lit.

Try these simple trick to find out yor remote control working or not....
Point the remote control towards the Camera of a Mobile Camera phone,with the camera on. While pressing remote, we can see a light (Infra Red) coming from its IR LED through the Mobile Camera if the Remote is working.
If your Remote is ok, then the problem with the Remote sensor or related components of the device.
