I'm thinking of trying to capture a close up of a mouse that I see in often in a specific spot on my D700. I've considered trying to use some automatic trigger based on movement. Is there an inexpensive way to do this? The only way I can find so far is to use a Zig View which looks good but costs about £250.
Meanwhile, I'm going to try and radio trigger and a lot of patience.
Isn't this an infra-red remote control trigger? I've picked up a radio trigger which I expect does the same thing. What I'm looking for is a way of doing motion detection so my D700 fires when something moves within a certain range.
I want to be able to set the camera up and leave it for a couple of hours, then when I come back see what's been recorded.
The Nikon ML-3 and knock off are both IRA They will do what you want. You can leave them on for a couple days unattended. The range is less than 30 ft. The object must break the beam between the sender and receiver. The camera can be connected by extension cord so that it is better positioned. So far that cord has been limited to 30 ft.
There are motion detectors that will work, but so far I have not found an affordable one. The long range radio triggers are not automatic. I have not found one that trips by motion or beam breaking, nor have I found any suitable relay for the ML-3 automatic trigger function.
Thanks for the extra information Roger. I think I understand now.
That sounds as though it'll do the job nicely... could also use it for some movement shots to. I think you're wise to recommend the copy than the nikon versions having seen the price!
This sounds like it'll do the job but I think I'll need to get the receiver away from the camera so I can run the beam runs across perpendicular to the lens. I'll probably need an MC-21 extension cord on the receiver to do that. I haven't found any cheaper copies of those yet though.
As far as I know, there are no knock-offs for the MC-21. I caved and bought one and it works well but it's only 10ft long. Cost for 3 of these is just too much, so I bought a second ML-3A for my 5D2. This version only has three wires inside instead of 10. It also has it's own battery, instead of using camera power. Thus I can use it stand alone with a 800SB flash unit. I cut the wire and put on a 2.5mm female stereo plug. I also put a male plug on the other side. I then picked up some aputure cables ($5 ea) from LinkDelight and a cheap 30 ft stereo extension cord.
Without and extension, you can run the TripLine on a diagonal to travel, thus giving your picture a better angle.
Another option would be to splice in some heavy duty ether cable to the 10 wire Nikon remote receiver cord.

If you plan on cutting the receiver to camera cord, I hope you ordered the 5D2 Canon version as 3 wires are much easier to deal with than Ethernet cable and the Nikon D3/D700 2.5mm stereo aperture cord will plug right into a 2.5 female jack.
A sure way of extending the 10 pin cable would be to just match colors on both ends and splice a piece of ethernet cable in between without any RJ45 connectors or couplers. I used cat-5e on one of my ML-3A receivers.
See DATA CABLE FOR NIKON F100 for the pin outs of the 10 pin plug. I believe it is common for the commercial releases to use the ring for the ground, the sleeve for the AF on, and the tip for the shutter release of the stereo plug. You may need to connect both grounds for this to work.
RRRoger, I purchased a YongNuo YN-218 on ebay for $36.80. The add on ebay uses the ML-3A designation in the YN-218 description. The unit appears to be a radio control (433Mhz) device instead of an IR device. I wanted this trigger to trip the shutter on my D300 or D700 if the beam was blocked between the transmitter and the receiver. If this unit will work, could you explain how to use it? Are there special camera settings that I need? Thanks. Ken Olson
Radio units will not trigger automatically although you might get one to relay the signal and if you do let me know. Mount it on a TriPod or set it on a rock, etc.
The receiver has to be within 26 ft. You can mount it on the camera flash shoe, TriPod, etc. An extension cord can link it to the camera.
I bought two for about $25 each. The Canon 5D2 & Nikon D90 versions only have three wires. I cut the cable in half and put a female stereo plug on it and male stereo plug on the canon adapter. I then bought a $10 Aperture cable that already has the male stereo plug on one end and the Nikon adapter on the other. A 30 ft stereo extension cable is dirt cheap compared to the 10ft Nikon unit. I have also plugged in a flash gun and used it to scare our Beagle off the couch. (no camera needed)
RRRoger, Thanks for the quick response. Where did you buy the $10 Aperture cable? Where did you buy the 30 ft stereo cable? Did you need a special adapter for the flash gun? By the way, I finally ran down FotoCola on ebay, and wouldn't you know, they have a new version of the two IR units that you bought that they claim is still infrared. I sure hope they didn't change to radio frequency transmission. I am communicating with them trying to find out before I buy. Sorry about all the questions, but as they say, "No sense in reinventing the wheel!" Ken Olson
Linkdelight.com Aputure PRO COWORKER Cable N1 for Nikon D300 D200 D2X R3C $5.00 $5.00 They also have a Aputure cable for the flash gun.
I think it was FotoCola that I bought the ML-3a from.
Do a search for Stereo cable extensions. Go to Radio Shack for the cable ends. Tekcetera.com has cheap cables but may not have long enough ones. Don't try to extend more than 30 ft because there is not enough power.
RRRoger, I searched the linkdelight web site, but I was not able to find the cord that you listed above. Could you please check their site to see if you can find it, and then let me know what keywords you used to locate it? Thanks. Ken Olson

Try this link as I could not locate same cable on linkdelight.com
Incidentally, a second reason to use the YongNuo remote made for the canon or Nikon D90 besides the 3 wires being easier to splice, The cable size fits the stereo plug. The ML-3a/N1 made for the D1-3, D300, or D700 contains 10 wires and is too large.
RRRoger, Thanks so much for the links and for your timely response. Dealextreme is temporarily out of the unit that already has the stereo plug. Because this is the chinese new year season, it may be some time before it is in stock again. If I buy the in-stock D90 version, I will have to solder the stereo plug on myself. Rather than playing "multiple choice" with the 3 wires, (usually black, white, and red), I need to ask you which wires go to the base, middle, and tip of the stereo plug? Also, will the stereo plug still allow the camera to autofocus when the transmitter button is pressed halfway, or does the camera have to be in manual focus to capture the critter when he/she blocks the IR beam? Again, thanks so much for all your help.
RRRoger, Thanks for the link. Do you have a master list of all these links? I sure would like to see your list if available. Do you have a favorite search engine for the web? Do you have a set of keywords that you use for searching this topic? As I said before, no sense in reinventing the wheel.
I went ahead and purchased 2 units from totobay.com. The shipping from them was $24. Usually, I get free shipping from China, but not from this vendor.
Like you, I like to use the AF-ON button for autofocus only (I set a5 to OFF) on the D700, using the shutter release for VR and metering only. I find that the RF remote releases will not autofocus unless I go back to using the shutter release (a5 to ON)for both focus and metering. Do the IR remote releases behave differently? I have never used an RF remote.
Also, do you know if the instruction manual for the Nikon ML-3 is available on line? I have trouble trying to understand the instructions provided by the Chinese even when they write them in English.
Sorry about all the questions. I'm just trying to get up to speed on all of this. Again, thanks so much for all your help.
It is very generous of you to send me the 33mb PDF file for the Nikon ML-3. I set up a new gmail account today which will hopefully be able to handle an email that large. I can't wait to see the manual so I can more fully understand the setup for getting a shot of the critters when they block the IR beam.
Do you have any critter shots that you have taken with the ML-3 or ML-3A?
Simple question: when using ML-3 (or Yongnuo) as IR movement trigger, does it make multiple photos after setup? So if I leave the camera out for couple of hours, will every movement during this period release the trigger?
