D-viewcam camera’s disconnected… connecting – at random keep getting heartburn

I went all nutbar getting into this camera thing after having my computer laptop stolen and the possibility of my address being gleaned from it, decided to protect the premises with my own setup, no monthly fees. Lady at FutureSHop told me this would fit the bill. Currently i have:

I currently am sitting offsite by my other computer running dviewcam (3.5.0) with all 4 camera’s inserted properly. I see all 4 and they are operating. However the current pattern seems to be that my 930L,932L and 2332L keep going down with big red DISCONNECT every so often. I haven’t timed it but it feels very random. Sometimes 2 cameras will go down simultaneously, most times just 1. They usually reconnect extremely quickly (within 10 seconds) after seeing the CONNECTING.. on the screen.. but sometimes it painfully fails many times over before finally reconnecting.


The 933L has not gone down all night. So one would assume the 933L being cabled does the trick? Well, i’ve seen it go down before quite often too, just seems to take a really long time before it goes down, but i know it does because my phone app actually gets a message in the notification bar that DCS 933L disconnected at 00:34 02:11:2014 or something similar.

1. It has something to do with ‘internet sessions’ but i have no clue what to do with it? I noticed the IP’s of the camera’s inside of the internet sessions along with a number counting down. I assumed it was some kind of timeout, idle or disconnection timer of some sort, and appears to be the case as the one camera ip i was monitoring, once it hit 0, disconnected on me) Again, i have no clue what to do about this. As i said, i’ve put all of them into dhcp reserve mode. Same as the range extenders. Should the extenders be set to a static IP? Sort of seems moot, i still had this problem when the camera was directly WPS’d to the DIR-615 so that kind of eliminates the extenders as a problem.

Unless anyone has anything else to add… my hunch is it’s the router is disconnecting the wireless camera’s based on sessions.. but i am at a loss as to how to either increase, or omit the camera’s from being served with such tiny timeout stats. At least the 933L (plugged in via ethernet) goes on for hours at a time, the quick disconnect reconnect is forgivable. The other not so much. It appears that the 933L is given the maximum timeout of 7800?

when checking the recording log, it appears that the 3 wireless camera’s disconnect exactly every 10 minutes, as it apparently ‘records’ for a few seconds at the moment of disconnect as if it were motion (i have it set to record only on motion for 1 second pre / 5 seconds post motion).

Also, ever since installing the 932L, my router has on 2 occasions now completely lost the wlan signal. Everything runs well for a few minutes/hours, then bam, all 3 of my wireless camera’s get big red X’s in mydlink lite app. The router is still running, my 933L connected via ethernet is still showing up, and the internet is still running, but all wireless goes down. Even tho i log into the router and it says wireless enabled.. no wireless devices show up and the SSID does not show up on any of my wireless devices. (it will show my SSID but say it’s not in range, even tho im standing right next to it)

When i get back to the location i am going to update the firmware on the 932L and the router to remove that from the troubleshoot list. I have also read that the dir-615 is not good at handling multiple connections. I have also read about the 615 running on dd-wrt and the atheros driver being known for dropping the signal, but it seems odd that the router functioned well overall until i introduced the 4th camera into the network.

Sorry for the delayed reply. I only came into owning one of these cameras, a DCS-933L, just recently but I’m seeing this issue that you’re seeing. I have a suspicion about this that I’d like anyone to look over with me having this same problem. What I’m noticing is that my router’s DHCP table, is generating an IP conflict of some sort. When I set up the camera initially, it was through wired means. My router gave it an IP address of 192.168.1.50 while it was connected via Ethernet. I then had it set up for wireless. My router gave the camera the same IP address on the wireless interface of the camera. It’s like it created an IP conflict for the same device, just on different interfaces as seen by the starting of the MAC addresses for the camera.

I’m on FiOS using an Actiontec router, model number MI424-WR with firmware 4.0.16.1.56.0.10.14.4. I’m not sure if it’s the fault of my router or something about the camera because I’ve not seen this type of error happen before. In fact, this wasn’t even an issue until I had set up options to use the Extender with a different SSID on the camera. I may consider turning this off to see if this disconnecting stops.

PLs may or may not be needed in some cases and is not recommended for general use in WiFi configurations. It’s preferred if any additional WiFi is needed that LAN wired configurations should be used along with any 2ndary wireless APs to help extend WiFi coverage if needed. PLs could be used if LAN wire is not available for installation in some buildings.

PLs would not be ideal between the ISP modem and main host router in most configurations. Traffic between the ISP modem and main host router is a crucial configuration which needs the best possible connection between them. Shortest length LAN cable between the ISP modem and main host router is preferred using CAT6 cabling.

Cameras should connect to any main host router and remain connected. If the camera(s) are not connecting or fail to reconnect, then troubleshooting of the environment and surroundings for configurations issues and or interferences should be performed before the assumption of additional wireless or PL devices is needed. If the environment is not ideal for wireless devices, then adding additional wireless would not resolve the problem and add to the problem.
