Amazon, E-Bay, Alibaba, etc are the place you can shop around. Check out Costco, Sam's, Lorex whether they have a package deal with much cheaper delivery cost. FYI, you do not have compatibility issues with analog systems. Any analog DVR supports any analog cameras. One more, select DVR that supports D1 or WD1 recording for each camera. Old DVRs were limited to CIF recording for each camera. Thus poor visual quality.

For home applications with a rather tight budget, the conventional analog systems would be OK. Good quality Cameras should be less than U$20 each and 8 Ch DVR less than U$40. Buy a DVR that allows D1 or WD1(960H) recording for each camera. HD- Analog systems, HD -AHD or HD-TVI, could cost a bit more than the conventional analog systems. Of course, if you play a budget of more than U$100 per camera, then IP camera system.

I do not think the chipset inside the DVR would support these features that you mentioned. Though Technically not challenging, you have to understand that the chipset already utilizes 100 % of the DRAM bandwidth allowed. No more bandwidth to enable the feature, for the most of the chipsets involved. If the cameras are analog or HD analog, you have to buy another DVR and T type camera signal splitter for feeding the camera signals to the DVR.

You may consider to go for HD -Analog system: HD-AHD or HD-TVI, as you already have BNC cables installed. These HD Analog systems - stand alone DVR, also support conventional analog cameras as well.

Challenging what for? Testing equipments? How to send or record? JPEG/4K/and 20 FPS.

The button battery is placed for keeping the exact time for date/hours/seconds. You need to adjust time manually when booting up the systems. Replacing the battery does not need to reboot the systems. No troubles. Go for it.

On line storage sounds Fancy. But it can record as small as its limited network bandwidth,as you may experience when accessing video with your smart phone. It does not increase the bandwidth. Just buy a HDD for stand alone DVR for storing good quality video at such a low cost.

Any analog cameras would fit, if B+ means Power (Battery) Plus.

The addition of two 720P highly likely over-loaded the CPU. You may Reduce the number of frames for recording the 720P, or use sub-streams for live view.

You may not need to worry: There are options for Horizontal Mirroring or Vertical Flipping video images on Cameras or DVRs.

For each mode(recording/preview/remote view of recording/remote view of preview), write down the camera number displayed for each camera.

Verfiy the translation one on one, each camera vs the number. Find out which camera is missing or its number assigned for each mode.

Could be a software bug? Translated to Camera 0 ~ Camera 15 from Camera1 ~16.

IP camera could cost more than U$100, a piece, letting alone the software cost. I would recommend HD-Analog cameras of HD1080P resolution, costing less than U$40, a piece and with its corresponding DVR.

It sounds analog system. Buy a new DVR Box supporting WD1/960H resolution, costing you no more than U$30, in order to save the cameras.

If getting better with two cameras plugged off, specially at night, that would mean Power Shortage.

Glad to see Sunny! You start to recommend 1080P cameras one day you will mention 3MP and more I hope the day would come soon when all monitors we are getting, by default, at least UHD-4K or UHD-8K and as low as less than U$200.

Sounds Confusing. Maybe it fails to play back video after recording (storing compressed bit stream) to hard disc. Be noted that Onvif cameras does not quarantee the successful playback of video stream.

For home application, D1/960H/720P/1080P would be fine. I mean they are not necessarily to be IP cameras,costing more. And More than 1080P could be over-kill.

I know HD-AHD DVRs support both HD-AHD cameras and anaog cameras at the same time. HD-TVI DVRs are likely to. Please make sure the HD-TVI DVR can support analog cameras and HD-TVI cameras at the same time. With compositve (CVBS/NTSC/PAL) feed to a HDTV or UHD, you would get the limited video quality of composite. The DVR may support output of VGA or HDMI of 1080P. Please check.

I remember seeing those in Mobotix. They are not necessarily to be 360 FishEye. Just simple 4 lens modules in a single camera, saving installation and wiring.

I do not have the number. No worth. It could depend on the quality of the cable and distance for being applied. Last time I told you 3 Mhz. But yours were 4.5 Mhz, I recall. No use to argue about. I would give a try, assuming 8Mhz bandwidth would cheat on customers. Everybody wishes to have more bandwidth. But destined to be limited physically. God rules. I do not think anyone would try to figure out those numbers. No pennies worth. That's the attitude for those involved. That's why I wrote "who cares as long as visual quality is accepted"

I do not know whys, either. There was a guy, Boogieman, who has promoted 4MP cameras for a quite while. He may know the reason whys? He will get you the answer if he is able to come around this forum. You may give him a bit time before you move down to 2 MP (1080P) cameras. They are supported by almost all NVRs.

In math, more pixels = more image detail, everything else remaining constant. And in my opinion, more image detail = better, everything else remaining constant. Being given a new trick, consult with your math teacher, if you do not understand the concept of Frequency. More number of Pixels do not always give you more image detail. Image detail represents high frequency components when mouldated and transmitted over the cable. The high frequency component is getting deteriorated when going through a some distance over a cable. Then starting to lose Syncs which are placed on rather low frequency band. You may have noticed this in all Analog HD system (HD-CVI, HD-TVI, HD-AHD), starting to lose color components that is placed in the high frequency band. To send 1080P over some distance over some quality cable is believed to a quite challenge. How to send 3MP, 4MP, 5MP, 8MP, things? The cheat is simply blurring down details, high frequence, possibly as low as analog camera signal band (NTSC /PAL) after low pass filtering. They know it was OK to send analog camera signal relatively long distance. Who cares as long as visual quality is accepted and the price is much much lower than IP camera's????

I guess you have been mis-lead. To record something does not mean much to an NVR. To be precise, it simply stores the compressed bit streams sent by the cameras that you hooked on. NVR plays back the videos on the monitor by de-compressing the bitstream from HDD or Network. The IP camera does compress the video into compressed bit stream, say 2MP/3MP/4MP/5MP, etc. Stand alone NVRs carry a chipset of a limited capacity to decompress the bit streams. Good chances that your NVR can not handle 4MP or 5MP cameras, unless otherwise specified.
