Grandstream GXV3610 disassembled

In the interest of completeness I’m posting my pictures here to show what the inside of the GXV3610 looks like. I couldn’t find this anywhere else, so here it is:



My goal was to remove the cable from the backside of the ball and run it through the small hole I had already drilled through the exterior wall for a Cat5 cable. The two sides of the ball unscrew easily enough, but you can see from the pictures that getting the cable out would have been a challenge. The wires coming out of the jacketed cable go to three different plugs. I could have made that work, although the weatherproof grommet at the back would have been a problem. The bigger issue is what the red arrow is pointing at in the second pic. That’s the mic at the front bottom of the camera. Or rather, that pair of wires goes to the back side of the mic, which is thoroughly coated with a white paste of some sort, no doubt for weather proofing. My only real option would have been to snip those wires and resolder them. Nah, that’s ok.

Instead, I went to Home Depot with the mounting ring in hand and found something like this:

Round PVC junction box

The ring does not line up with standard 4″ round electric boxes. However, it’s a perfect match with this junction box. I had to add some caulk and foam backing material to seal the gap, but it’s closed tight now. I’ll snap a picture of the mounted box and post it.

The camera is working great. Good FOV and sharp picture. I have the 720p model, not the full HD.

Logitech 700e security camera disassembly

My 700e security camera failed after a couple years of use.  I got a Grandstream replacement, which I’ll also post about, so I figured it would be good to take the 700e apart and see if I could figure out what went wrong.  Figure it out I did.  And since there’s a lack of documentation and photos for taking the thing apart I thought I’d put it up here:

First, pop the top silver cover off by slotting a screw driver down the side to pop out the tabs:




Once the silver cover is off you need to remove the 6 screws across the top and gently insert a small flat head screwdriver here:


All you’re trying to do with that one is break the seal. After the seal is broken the darker color cover comes right off and you have this:


Bonus points if you can guess what my problem was:


Remove the screw from the metal plate at the ethernet jack end. Carefully pry up the circuit board from that end. There’s also a slot on the plastic end plate that you can use to help it up. Once it’s out you can carefully raise the board up on the angle, although the cables going to the camera board are still attached. Here’s what I found under there:


Yep, that’s white corrosion all of the top of the Ethernet jack, the lower right corner of the board, and all around the edge. Just below the (I think) transformer on the right there’s a bright white spot. That’s actually a pile of corrosion on top of several resistors.

So, there you have it. A disassembled Logitech 700e security camera. I’m going to try an eraser on the corroded bits and see if it wants to come back to life. I’m not optimistic, but I’ll post back if it works.

Grandstream GXV3672 internals

I’ve had a Logitech 700e outside the house for a while.  For some reason it died recently, first working intermittently, and now not working at all.

I’ve been looking at the Grandstream GXV series cameras, but I’ve been able to find little information about the mechanics of how they work.  I found a cheap used one on Ebay and took the plunge.  What I found right away was that it had been setup with a password.  Unfortunately the factory reset button on the GXV3672 is buried inside the camera.  I had to go hunting for it since I couldn’t find any info on it anywhere.  So, with that in mind I present the inside of the GXV3672:

Opening the front of the can is simply a matter of unscrewing it.  The rest is also pretty simple, but you have to be careful to not pull apart the cables as they are “glued” together with a little bit of colored gel.  In the picture, the bottom ring is the IR LED board.  It’s held in place with the two long posts sticking out of the can.  Beneath that is the camera board (square) which has a foamy ring that has to be carefully removed.  Underneath that is the round board in the center of the picture.  The 4 brass posts you can see at the top of the pic standoff the camera board from that control board.  Again, it’s quite easy to take all of that apart, but be careful of the cables.  Looking at the picture, the factory reset button is at the top of the control board.  However, when installed, it’s on the underside.  If you knew it was there you might be able to use some sort of hook to push in the button without having to disassemble the other boards.  For me, I held it down for a few seconds with power connected and it cleared the config.

I also wanted to see if it would be possible to unplug the cables from the back.  The cables feed out the mounting post and have rather large plugs for the RJ45 and audio.  If I wanted to run this through an exterior wall it would mean drilling a really big hole.  I was hoping to be able to remove the cable at the other end, but that seems like too much of an effort, especially if I’m up on a ladder for putting it back together.  Incidentally, the orange colored thing inside the can is a heating pad.

So, there you go.  Because of the dearth of  information on these cameras I’ll be trying to put up more info as I work on them and use them.  I might be getting a GXV3610 as well.
