Webcam Replacement Follies…   Leave a comment

1 SEPTEMBER 2015

Last May (Memorial Day week, to be specific) I finally got the prep work done to be able to do what I’ve wanted to do since I started using security webcams at the BallotBox, mount a weatherproof webcam up under the eaves on the outside of the house, aiming at the front yard and driveway area. I chose a Foscam FI9805E 1.3 Megapixel 1280x960p H.264 Outdoor Power Over Ethernet (POE) IP Camera. I use indoor Foscam cameras and like their functionality and software interface, and Foscam runs occasional on-line sales via directed email to their registered customers. I got it for less than half the list price.

Power Over Ethernet (or POE) is a common commercial and professional camera configuration that delivers device power over unused wires in a standard Ethernet cable, which for me means that I don’t have to wire a 120v 60Hz AC weatherproof outlet up under the eaves of the house along with an Ethernet signal cable (yes, I know they make wireless outdoor cameras but wireless signals get iffy over distance with lots of solid wooden things like floors and walls in between). I had the camera, I bought a POE injector (a power supply that injects 44-57v of DC power onto specific unused wires in a CAT5 Ethernet cable as per the IEEE 802.3af standard), I ran about 45 feet of armored direct-burial-rated CAT5 cable along the rafters in the cellar then out a hole in the sill then up a conduit to the location where the webcam would be mounted, and I spliced RJ45 connectors with sleeves on both ends of the cable. I was ready.

Disappointingly, Foscam chose to wire in multiple methods of connection for the FI9805E, so there was the black POE-capable RJ45 LAN connector I wanted hanging off the back on a 2 foot cord, ALONG WITH a black alarm connector, a black Audio-in connector, a black RS485 connector, a black audio out connector, a black power-only connector, and a black reset button, all on a 2-foot cord.  Seven cables with seven connectors, six of them I did not need or want. Sigh. I packaged up the unused connectors into an elongated bundle, let the RJ45 LAN connector hang a bit lower than the others, then mummy-wrapped everything in white electrical tape (to hopefully blend in with the white trim on the house), except for the end of the RJ45 LAN connector cord.  It looked like a small white snake had swallowed a large rat.

IMG_20150529_170458491I extended my Little Giant hinged extensible ladder up to the spot where the camera would be mounted and tied neck lanyards around my DeWalt 18VDC cordless drill AND the webcam so I could hang them around my neck to keep my hands free while climbing on and standing on the ladder.  I stuffed a screwdriver, screws, a Phillips-head bit, drill bits, pliers, and a hammer into my pockets for the vertical climb and headed up.

Slowly and meticulously I mounted the camera bracket and the camera to the side of the house. I plugged in the Ethernet cable, checked the “IP Cam Viewer” app on my phone, and VOILA! There was the side of my head on my phone!

20150529-1558-BallotBox1bI slowly (and gratefully) climbed down off the ladder, emptied my pockets, put away my tools and my ladder, and sat down at my server to finish configuring the new webcam in my Blue Iris webcam management software.  The high-resolution camera provided a delightfully crisp and detailed image.

In Blue Iris I can configure various things to happen based on triggers, and triggers can be motion-based or time-based; If something moves in the field of view, I can have Blue Iris send me an email – with still images and/or video clips of the triggering event – and/or I can have Blue Iris record video of the triggering event and archive it to the local server and/or a remote storage location via FTP.  I can also take a snapshot of the camera’s view every X minutes apart and store the images locally and/or at a remote storage location via FTP.  I can also have Blue Iris take a snapshot at the same time every day and store the images locally and/or at a remote storage location via FTP.  These three things I do.  I can also specify when during the day (8am – 8pm, sunup to sundown, etc.) these things happen, but I run surveillance 24×7.

I can also (thankfully) adjust the sensitivity of the camera to the triggering event, and the area of the field-of-view to pay attention to (motion in one area of the image triggers an event, but the same motion in another area of the image does not). Set highly sensitive, I get repeated emails (sometimes hundreds) when it rains at night and each individual raindrop gets illuminated in infrared as it streaks by. Some night-flying insects apparently also fluoresce under infrared light so I get emails when the bugs are out. The first few days after the initial end-of-May deployment of the under-eaves camera were quite rainy at night, so I got 6-8 HUNDRED emails per night. TOO SENSITIVE!!

BallotBox1a.20150601_041310_757147Also poorly-installed.  My white electrical tape bundling of the unused connectors inadvertently left the RJ45 connector jack on the camera facing UPwards, so the jack acted like a small rectangular rain gauge, collecting rain-water, which shorted out the 44-57 volts of DC power and damaged the camera. It lasted about 10 days.

Next trip up to Maine (19-21 June) I climbed back up on the ladder, unmounted the camera, brought it down for testing, and determined that it was dead.  It was still under warranty so I sent it back to Foscam for RMA repair.  It was returned to me mid-August.  I tested it out and it worked perfectly, so I re-taped the unused connectors into an elongated bundle again, making sure to arrange the RJ45 connector jack so it hung facing DOWN this time!

This past weekend, after spending most of the weekend priming and painting the (now not-so-new) new deck at the BallotBox, I got time to haul out my ladder and climb back up under the eaves and re-mount the repaired webcam.  The damn thing still didn’t want to cooperate. I got up there (up on a ladder is not my favorite place to be, as you may have guessed by now) and remounted the camera, plugged the POE Ethernet cable in, configured the RJ45 connector jack to hang DOWN this time rather than up like a rain gauge, taped the connection to keep any blowing water out this time, and fired up my cell phone webcam app (from up on the ladder) to re-aim the camera in real time… but no signal.  WTF?? I poked around a bit but finally decided I needed to access the feed from my computer in the basement.  Down the ladder… still no signal.  First I suspected the POE power injector so I swapped it for the injector I have on the twin camera aiming out the back deck slider.  The suspicious injector worked fine on the other camera, so that wasn’t the problem.

When I took down the camera a few months ago before sending it out for repair, I cut off the old RJ45 plug and re-crimped a new one while up on the ladder in case the water-based shorting damaged the plug, so I decided I had crimped the plug badly.  I loaded up my pockets with networking tools (crimper, wire cutter, scissors, blank RJ45s, and my color wiring diagram cheat-sheet) and climbed back up the ladder.  Slowly and meticulously I cut off the old RJ45 and crimped on a new one while hanging onto the ladder and trying not to lose my balance.

BallotBox1a.20150830_145335_757147Down the ladder… check the feed on my computer… still nothing!  I was getting annoyed now.  The camera was working perfectly when plugged into the POE injector with a short cable in the basement, so the source of the problem had to be the armored direct-burial-rated CAT5 cable run from the POE across the basement ceiling, through the sill, into the conduit and up the outside wall of the house.  One RJ45 connector (up under the eaves) had just been replaced, so I decided to replace the RJ45 connector in the basement. That fixed it.  Back up the ladder one last time to finally re-aim the camera, and got this lovely portrait of my left ear emailed to me in the process.  Motion-detection sensitivity was set low, but not off.

By then it was time to take a shower and scrape off all the dried paint on my hands from the deck work so I could catch the DownEaster train south to ARTC in Woburn.  Next weekend (going back up on the train Friday morning and down on Monday evening) I need to adjust the motion sensitivity – I set it off when my face was right in front of the camera when I was back up on the ladder and finally able to re-aim it in real time, but I had desensitized it back when I was inundated with rain-generated emails the first time, and cars pulling up the driveway won’t set it off now, and people walking around definitely won’t set it off. The every-two-minutes image capture is already being FTPed to the BallotBox web server for near-real-time viewing.
