Cameras And Fields Of View For IP POE Home Security System

[sichuan 0]

I need some assistance with cameras and angles of view. I've spent weeks researching different issues such as frame rates, resolutions, megapixels, data flow rates and angles of view and I'm still not competent enough to arrive at certain conclusions. I'll be using an 18 port/18 channel IP POE NVR. I'll be connecting each camera to an individual port on the NVR with Cat6a cable. The NVR and all the IP POE cameras will be Hikvision USA products.

 

Here's where I'm at now: I've designed it as a 13 camera system, using 11 turrets and two bullets but I'm certain I can lower that to nine or ten cameras if I select the proper cameras with the proper fields of view.

 

North Side Of House Photo 03: You will notice that the part of the house to the right of the front entry door extends out four feet. North Side Of House Photo 04: The front yard is 115 feet wide and 60 feet to the street. Currently, I have configured three turrets and one bullet to cover the entire yard, the front windows and the front entry door. Two of the turrets, model DS-2CD2332-I-2.8MM 3MP (86 degree angle of view) would be mounted on the soffits angled straight ahead in such a way that I can view the entire front yard using these two turrets. The third turret, model DS-2CD2332-I-12MM 3MP (20.6 degree angle of view) would be mounted above the front entry door for identification of anyone at the door or approaching the door. You will notice the large Oak tree in North Side Of House Photo 04. My intent was to remove the lower branches and install a bullet camera, model DS-2CD2232-I5-6MM 3MP (25 ft. wide view) on this tree to cover all five of the windows. The front entry door cannot be seen from the tree.

What I'm asking is: Instead of using the configuration I've just mentioned can I mount a turret on the left corner soffit, angled toward the street sign/stop sign in such a way that I can cover the two bedroom windows on the left side of the house, the entry door and the right side of the front yard, and then mount a turret on the right corner soffit, angled toward the left side of the front yard, in such a way that I can cover the three living room windows on the right side of the house and the left side of the front yard? I assume that I would use the two DS-2CD2332-I-2.8MM 3MP turrets(86 degree angle of view). This would reduce the number of cameras I need from four to two, eliminating the turret over the entry door and the bullet on the tree.

 

South Side Of House Photo 01: This is the back yard. It ends at the yellow gas line stake. The yard is 125 feet long and 115 feet wide. I want camera coverage for the entire yard. Currently, I have configured two DS-2CD2332-I-2.8MM 3MP (86 degree angle of view) turrets to be mounted on the soffits in such a way as to cover the entire back yard. I think these two turrets will cover it, although I may need three of them. I don't know. I had originally wanted to mount a bullet on one of the trees shown in this photo, the tree facing the garage windows, but I've eliminated that one. South Side Of House Photo 02: This is a closeup photo of the back of the house. The two evergreen trees have been removed. I want to cover the garage man door, the patio sliding doors and the two windows. I'm going to use a turret, model DS-2CD2332-I-2.8MM 3MP (86 degree angle of view), for this coverage. I can mount it on the soffit above the tall evergreen tree or I can mount it on the soffit above the tree with the weeping branches. I think it would be better to mount it above the tree with the weeping branches. Will this give me a wide enough angle of view to capture the man door, the patio sliding doors and the two windows?

West Side Of House Photo 02: The west side of the house is 50 feet long and it's 35 feet from the side of the house to the street. The two evergreen trees on the sides of the driveway have been removed. I have configured two turret cameras to cover the driveway, the window and the side yard, both turrets being model DS-2CD2332-I-4MM 3MP (70 degree angle of view), the two turrets located on the soffit at each corner facing the opposite corners, the one on the northwest corner facing southwest and the one on the southwest corner facing northwest. I could replace these 4MM turrets with 2.8MM turrets if you think they would give me better angles of view. Are the 4MM turrets sufficient or do you think I should switch them for 2.8MM turrets?

East Side Of House Photos 01 and 02: I have configured two turret cameras to cover this side of my property, model DS-2CD2332-I-4MM 3MP (70 degree angle of view). They will be mounted on the soffit corners facing the opposite direction, the northeast corner camera facing southeast and the southeast camera facing northeast. I don't care if the field of view covers part of the neighbor's property. I think I'll leave this as is because I don't think I can get good coverage using only one camera. In addition, I can cover parts of the front and back yards that may be missed by the the turrets covering my front and back yards.

South Side Dining Room Photos 01 and 02: These photos were taken with a cell phone so they're not indicative of what a turret camera will show. Photo number two was taken from the upper corner shown in photo number one. I've configured a model DS-2CD2332-I-4MM 3MP (70 degree angle of view) for this coverage. It will cover the kitchen, part of the south side dining room, part of the west side dining room and some of the front entry door. This coverage will allow me to see anyone coming in through the garage entry door into the kitchen, the front entry door and possibly the patio sliding door entry. These are the only three entries into the house. I think if I switch to a model DS-2CD2332-I-2.8MM 3MP (86 degree angle of view) and locate it on the wall or ceiling above the hutch it will give me more coverage of the patio sliding door.

I'm using turrets instead of domes because they provide a better and more uniform IR light and I eliminate dome reflection from the sun and inside lights. I'll be using the model DS-9616NI-ST-4TB IP POE NVR because it produces a 1080p display for all the cameras.

 

I'm looking for any suggestions that would either validate my conclusions or improve my choice of cameras and their locations. Thank you in advance for your time and any assistance provided.

you must have used one of the many FOV caculators that are available online for your planned layout if not there is one on this forum. If you have picked a mfg for your camras why not just purchase one each of the domes with the different lenses then you can temp install them and view on laptop or your nvr. when you have done this you will know your exact count and what lenses you need/ The only way to really tell what you are going to see is what you want is to place a camera and see what the pic is like.

Hi. First that NVR is 4 years out of date ........ And it will not run all your cameras at full res

 

Then you have the problem of it NOT being a POE unit. So you need a good POE switch

Thanks, Tom. You're absolutely correct. I listed the wrong NVR. This is the one I had chosen first but I then learned that it will display in full resolution for only 8 cameras.

I'm still looking for a 16 channel, 16 port IP POE or IP POE+ NVR, H264 or better with a gigabit Ethernet port, one that will handle cameras up to 4 megapixels each, one that will run all the videos at full resolution and will automatically discover all the cameras. I suppose it's called a Plug N Play NVR. I'm going to run all the cameras in real time 24 hours a day so I'm looking for at least 4 SATA connections that will handle up to 24TB of storage. 24TB may not be enough storage. I may need up to 8 SATA connections that will handle up to 48TB of storage. I go to China quite frequently for weeks or months at a time and I'd like to be able to store the videos in the event the police need to view them if there's a breaking and entering. The NVR will be connected to an UPS. I'd like to be able to find an NVR that automatically powers itself on after a power outage if the duration of the outage exceeds the capacity of the UPS but I don't think I'll find one. It's not that important because my neighbor watches my home whenever I'm in China and he has a key to the house. If, while in China, I notice that the system is not running I can always have him go over and turn it back on.

 

I'll be using Hikvision cameras and a Hikvision NVR made for the U.S. market but instead of dealing with a Hikvision USA authorized seller I'll get Hikvision rebranded cameras and a Hikvision rebranded NVR from LT Security Inc. I think the rebranded cameras I'll get from LTS are the exact same cameras I would get from a Hikvision USA authorized seller. It's not the gray market equipment made for the Chinese market that has been hacked for the U.S. market that you see on Amazon, Ebay and elsewhere. I'm almost certain LT Security has the NVR I want but I'll have to wait until Monday to contact them. The support I get from LTS is very good. I haven't even ordered the cameras and NVR yet and I've received excellent support from them regarding any questions I've had. I imagine the LTS support is every bit as good as the support I would have received from a Hikvision USA seller. I couldn't be more satisfied with LTS.

 

I do want to ask you one question. The cameras I'll be using are all 2.8MM except for two of them, which will be 4MM. They will all be turrets with the exception of 2 or 3 bullets. Since this is a home security system and I'll be displaying the video streams on a Samsung 24 inch LED 1080p monitor do you think I have anything to gain, as far as video clarity is concerned, by going from 3MP cameras to 4MP cameras? Of course, with my limited knowledge of IP POE systems, chances are good that I may be barking up the wrong tree and the difference between 3MP and 4MP megapixel cameras could have no effect on the clarity of the video display.

 

Thanks again, Tom, for your time and your assistance. I appreciate it very much.

Hi. Why not look at dahua as well ...... You will save on HD space as well as going full res on all channels

Thanks, Tom. I spent a long time researching Dahua IP POE cameras before, along with Hikvision and many other brands. I finally narrowed the decision down to Dahua and Hikvision and then finally chose Hikvision. I think they're both comparable in price, quality and performance.

You will waste your money ..... No room to upgrade and is h264plus which is not compatible with the new h265

This is 100% correct.

 

You first thing you need to define will be the purpose of each camera. (monitor, detect or identify).

 

For example, you can cover an entire football field with one camera, but will this provide usable video (yes if you want to see movement, no if you want identification)?

 

The critical measurement is pixels on target, for example in the UK, 125 pixels per metre on target is regarded as adequate for identification.

 

This will help you define lens size and recorded resolution requirements for a defined distance from the camera.
