    What does make so expensive to IPC-HDBW8232E-Z 2mp camera?

    It will have larger "pixels" on the chip, so better capable of capturing light that hits the chip than of a smaller chip with equal amount of pixels. It would need a better lens also, and with the added compute power the costs add up.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    You could use the same approach i intend to take: sensors I will use these 2 ptz for keeping eye on back garden. That is basically U shape so 3 sides. In normal mode, both watch the back side (no visability of the sides) there is line crossing sensor for the side fences. When someone climbs the...

    Opps!

    My oppinion: the size of the car is not 1:1 with drivers quality, or better the bigger the car, the driver gets worse.. We have in our country "PC hoofd tractors" These are very big SUV cars where the happy few wifes drive in (as in Porsche, Mercedus Benz etc) they ingeneral need 2'parkimg...

    New Dahua install

    So i finally ordered the ptz cameras. Decided to go for the sd49225-hn due to cost. All the posts about the autotracking of HNI verisons of the 5xxx series did not convince me in investing almost the double amount. As written above i will hook up IR line sensors along the fences upper part and...

    IPC-HFW4431R-Z still the best varifocal for under $100?

    Did you spend all you money on the insulation and air thightness etc than not being able to spend that few $ on a good camera ? I am now in the building process, and the whole insulation and air sealing costs soo much, those few cameras are noting in comparisation.

    Yes the damage shown in the opening post seem induction from the leads to earth over to electrical wires. We need to have the electra lines more than 50 cm from the leads down to earth if i calculated it right. But still than induction might occur. So solve this every electrical outlet must...

    Dahua IPC-HFW8630E-Z 6MP Ultra Smart Bullet

    Yes, you normally can ping most things that are IP connected. And most of the time they should rspond for 100% of the requests. But if you miss 1 out of 400 you should not simply conclude it it the cable for example. For this case it seems indeed the camera has issues. Not much reason why the...

    Dahua IPC-HFW8630E-Z 6MP Ultra Smart Bullet

    Well, a camera should not give priority to answering icmp packets. I work in IT and seen very expensive cisco Nexus switches drop icmp packets if you do that against the control plane. When you test through it, they never drop one packet. (Speaking of 10GE links there) I do not want to say the...

    That first link shows me that the proposal i received makes sense. Type of roof is: Mansard and that show a ring on the topside and 2 runs down. Also the specific length of the rod's are mentioned: the air terminal tip is located at not less than 10 inches above the protected object if the...

    Old thread, but i am now thinking a lightning protection setup for new to build home. Companys here advise the following: - rods on roof (quite high with 2 meters length) - ring around the border of the flat roof top. - 2 runs down to the ironworks in the concrete fundation of the home which is...

    Large installation Multiple Switches

    Defenitvely use managed switches. This allows you to create vlan's so you could seperate general wifi from camera traffic. It does add some complexity if you need to remotely access the cameras though. You than need some kind of layer 3 device which offers multiple connections on the LAN side. I...

    Advice wanted - planning 1st install

    Well for one the lens on the ipc-hdw5231r-z starlight is a f1.4 and the one you attached a sheet from is a f2.0. Besides that the chip used is completely different. Why do you try to push this kind of inferior camera for night time use to someone asking for advise ?

    Two guys stole my security cams :(

    Perhaps install them so the have each other just in the picture, example these swapped aroundfor the direction ? Would not have helped perhaps against this person with such a big hat. Is that a Mexican one ?

    Dahua NVR don't recognize Dahua cameras (screenshots attached)

    It wont work for you when you have non 10.x.y.z addresses like the 192.x.y.z you seem to have.. Only thing to do is put a device in the same subnet as the camera and log on to the web interface, and change the ip address for the normal prefix you are in (10.x.y.z for most people) and change the...

    Anyone paint HDW5231R-Z? Issues?

    I am really happy with the tax free shipping. This is to Europe about a good week, but not tax from the greedy government is very nice. But i think Andy pays tax for us. (Just to put it right)

    Dahua NVR don't recognize Dahua cameras (screenshots attached)

    First is that 10.100.102.x the subnet of the POE connections on the nvr itself. Perhaps you connected the camera there so it got the ip address there. Try to stick it back there and see in the nvr gui if you can connect to it. If you want to have the camera on you main lan which seems to be...

    I unpackd my 5416 and powered it on. It sounds like a vacuem cleener.. This one has: psu fan, case out fan and cpu fan on heatsink. It will go in a technical room in the new house, so i will not try more silent fans yet. Only if it is too much in that room. The case is 1.5 U high so the fans...
