@Hans007. dahua part numbers have all kinds of variations. I think best to read the detailed specifications for the options you want. dahua numbers are complex and without the "code" almost impossible to decifier.

@looney2ns 1st knob adjusts the brighness level. The 2nd is for dusk/dawn sensitivity. Photos posted are with brightness turn all up. Dusk/dawn adjustment does not seam to do much. It seams to turn on a little early in evening, but at 7w I don't care much.

@Ajpepe72 Based on your earlier photos they look white to me. See if you can find a color range spec. in documentation. Ideally dahua cams like the 5500-6500k range. Other ranges work but the 5500-6500 gives the cams what they likes best. Cameras are "light collecting devices", feed them well...

Here's some photos to show both the PFM 510 and PFM 511 models as compared to each other. The tree marked with arrow in the far back is 80 yards out. The closer tree is about 35'

@CCTVCam it should be possible to wire directly in on the photo cell (dusk/dawn sensor) connections. Supply the same voltage from your trigger. There is no delay or warm up phase. Just on and off. You wouldn't want your cameras to auto change modes but it should work good if cam is set to...

dahua also make really great quality LED lights. They list them as IR but they're really 5500-6500 white lights. I have two of the 7W (PFM511) and the 15W (PFM510). The 7W is great for most areas. The 15W does reach out better for longer distances ( over 40 ft/12m). Small overall size (4"...

I don't have any experience with sticks and not sure if BI would run on them very well. If your looking lost cost and small, have you considered the Rasberry Pi3? Small foot print, low cost (like $57.00 or about) good power, runs linex with ethernet and display ports. Do a search on what @nayr...

@greg_mitch The display I use is a seiko 39" UHD fed video from my home theather computer. This system runs win10 on I7 w/ a Geforce GTX1060 6 gig video card. I output direct from the card to the Seiko with a UHDMI cable. Took a while to get win10 to let my GTX Card to output display at 4k x...

do a search for optex OP-08. It is tempeture difference sensor that are comon on automatic store front doors. I think @nayr did a post on one he uses.

I do really like this CM130. With 198 LED bulbs the uniformity of the lit area is very even. My 850nm, 6 bulb LED's light has a very bright hot spot area. I recently added a thin (.020") opaque plastic sheet in front of the 850, and it did help diffuse the light, but I still have a hot spot...

All my Dahua see them just fine:) I added a amazon link above if anyone is interested in the CM 130.

@ZyBeR They list them with IR range but I would not really consider them "Infar Red). IR 850nm has the "red" bulb glow and work well if you want an area to be dark but yet a person can see the red glow on the bulbs. IR 940nm has no glow and are used in areas where you want cam vision but yet no...

@weigle2 PTZ not zoomed (full view) Well lit large tree is about 35' from cam. LED is temp. mounted at 8 ft high just under my house eve. PTZ @ 10' and about 12 ft to the side of the LED lights. For a 30-40 ft. range the 511 (7w) is great. My plan is to use the 510 (15w) more in the length of...

Here's some photos to show both the PFM 510 and PFM 511 models as compared to each other. The tree marked with arrow is 80 yards out.

@bp2008 Not sure how they do it but only see the 6 LED bulbs so they get night IR lumens and bright white light. This allows the cam to work in either Black & White mode or Color mode. I guess it wouldn't really be infared as you don't get a dark area and red light covert effect, but for my...

I've been using a DH-PFM511 for about 2 months now. Absolutely love it! So much I ordered a 2nd 511 and also a 510 that DHL will deliver tomorrow. Of Note - 1) Great "feel" & quality full metal housings just like their cameras! As a design engineer I can REALLY appreciate the quality of...

@mlapaglia , lol. "IF" I open my door I no longer feel so paranoid, and don't need to record my guest anymore.

2.8 mm. It works well as my walkway is only 14' out.

@smoothie After 30 + days of use now I can say I am extreamly happy with this camera at this location. Sure I would like a bit smaller on the outside but this being a Starlight gives me the picture I was wanting day or night. My entry sits back 4' in a recessed entry area. This cam in coridor...

Ok so here is the final painted instsllation. I hollowed out the inside of the hole enought to stuff the wire and connectors inside the door (& small white plug). I use cat6 flat white and little monster white wood glue to tack cable down. repainted white door. Also painted camera housing to...

for right now I just used some clear tape and routed the PoE wire over to hinge area and loosely "looped" it directly over the hinge area. Having a white door it blends in well. I'll add a small white plastic wire cover soon. Here is a photo without the cover on the camera to show how small it is.

What a super little camera! (now only $96.82. Oscar@Jimbu Security) you can't go wrong with this great little camera! 10 days from order to delivery using free epacket. This cam could be mounted on the inside of a door by cutting a small pocket (approx.2"x3"x1" deep) in the door. The thickness...

you can also use combinations of trip wire (or multiple trip wires) and then an intrusion box behind the line in places. I find the combination to bemore effective overall. Also agree with aristobrat with trip wires being close to edge of image. They look for image changes. I find they work...

Andy gets more in a couple times a month. The 5231 Statlights are well worth waiting for. Check Andys post tomorrow or Wed. He will update again soon. He's filled a lot of orders already so hopefully he is allmost caught up.

depends on many things. Moon light, street/city lights, stars. Test a few different nights in the month (ie moon phases) with your lights off and camera set each way. These cameras are great at low light gathering, it just depends on how many sources there are and how much they provide in your...

Fenderman, How about starting a forum post area just for ANDY. Then he could use that area to post his current inventories, expected dates and other notes. Restrict it from others so it could be clear in one location w/o all worthless ramblings.

WD Blue HDDs for general purpose storage. WD Green is basically the as Blue,.. WD Red is a NAS drive. ... WD Purple is for surveillance. ... WD Gold, most premium of all.

70% Isopropyl Rubbing Alcohol and a clean micro fiber or cotton cloth. Cleans well, safe on clear plastics and evaporates quickly.

or some small trip wire..... be a good tumble down that hill. lol
