Hi guys, The camera is performing fantastic during daytime but at night not so. Shutter speed is at 1/60 and I'm recording at 20 fps. auto iris is set to ON but setting it to OFF does nothing. So hopefully it is fully open at night. Can't really tell. Is this the best this type of Dahua camera can do or am I missing some important config setting? Please see attached screenshot. As you can see, the car is very sharp but I'm blurry face.

lens pack? Please explain

Hi. Yes they are very good sensors we use them all the time 9v battery keeps them going for well over a year You also need the controller which you buy with the amount of zones you need Got one controller for the 3 sensors. Downsides are the limited angel they can cover (only 75°) and they don't really have pet immunity besides a flat beam at 1 metre 50 height. Optex wireless was a tad too expensive unfortunately as they fix both issues.

Just to share I found these: http://www.gjd.co.uk/products/wireless-detectors/opal-rfx-gjd018 Looks like good value for wireless PIR!

Thank you sir! I just ordered a DH-NVR4204-P NVR from Dahua

I have 3 camera's from Dahua and I'm looking at a DH-NVR4108H-8P NVR with 2 alarm inputs. - When alarm input 1 is triggered, can the NVR software be told to record ALL 3 camera's? - When alarm input 2 is triggered, I would like to have the NVR record from 2 camera's Or is there a 1:1 relationship between an alarm input and a camera? Many thanks for your time.

Since my last question on how to use a PIR, I did a whole lot of searching and I can narrow down my question. Can someone please tell me where I can find a wireless PIR-sensor which sends a signal to a base station which I can in turn wire to a DVR? So to depict a clear picture: - I'd like to place 3 wireless PIR-sensors - the base station (= device that receives the signal from a PIR-sensor) should be able to identify which sensor has been triggered and wire that specific sensor's alarm output to an alarm input on a DVR Does such a system exist? Many thanks if you point me in the right direction.

Hi there, I'm trying to improve detection so I want to connect a PIR sensor to a Dahua SD42212SN-HN and have it start recording when motion is detected. So I don't want to use image detection any longer Can someone point me in the right direction as I'm still in the basic stage of understanding. - How do I power the PIR sensor? The camera is powered by POE+ (= IEEE 802.3at) - What is the camera expecting as an input alarm signal? Is every PIR sensor compatible (don't want to ruin the camera) - Is the detection range (width and length) adjustable? I want to detect an area of 30 meter deep to 15 meter wide - Will it all go wrong if it is in the sun as the sun gives off infrared too, or more general, can PIR sensors be easily subverted by a burglar? And in stage two, I want my floodlight to go on at the same time. It would be nice if that can be done with one PIR sensor. Sorry if these all look like stupid questions

Yes, the center of the frame is just fine as it's a straight walk to the street and the car is always parked in the same spot). I'm going for a BOX because it is seemingly very hard to find a good PTZ around $750. I've got to cut back somewhere but a PTZ is the best choice technically.

Hello again:-) Just as I was biting the bullet for the ACTI 7811, I went to take a more closer look where it would get installed and, unfortunately, a varifocal lens is not enough. I managed to drop the demand for a dome as a box camera with zoom is much much better for the application (sometimes people just won't listen until you talk price). I'm looking at the $700-$750 price range. That's not going to get me an ACTI 5611 where I live as they retail for about $1300. It is not going to get my any Acti box camera with zoom as all of them are at least $850 and up here. What's the next best thing I should be looking at? I need about 15-17 meters of night vision from the porch to the street (to guard the a car). It is not pitch black but the street lights are 5 meter further on a larger street parallel to the street the car is in (so there is some light the camera has to fight). Facial recognition is a requirement and that is the reason for selecting a zoom camera. It will also be used to capture ppl walking up to the door. A acceptable day time image is of course also required:). Thanks again for leading me on my way:-)

It is going to be the 7811 probably. It's not my choice but I still think it is not a bad one. Going to look for a shop here in Europe as we want it installed before the Holiday frenzy starts off.

That sounds way too hard giving the zoom / focus controls to an additional board. Also, the camera would not be able to zoom in automatically when motion is detected as it has no means to control the zoom/focus itself. a KCM 5611 camera with a Pan - tilt motor is looking more attractive and such motor does seem to blend in with the camera firmware (I.E. the camera can control it automatically when required). I have only just discovered this neat option and I like it:-)

I have a small question out of interest. Can the Acti 7811 be fitted with a motorized zoom lens and then control this lens via whatever protocol is used for this (RS-485 possibly)? With control I mean, operate the zoom and maintain focus across the entire zoom range.

Thanks for the confirmation. I'm going to do the math because for the FOV because I feel he does not really need PTZ. I assume you can always zoom in electronically if needed. Thanks again for your help, your review made it easy to pick something suitable:-)

The answer is probably no but can it pan and tilt via software commands? Motorized optical zoom is not really needed so a PT without Z will do:). And judging from your review this on is definitely adequate for my needs. If I could just get the same one with pan and tilt. But I think that is not going to happen below $1000?
