CCTV DIY DVR and NVR video recorders (CCTV Server DIY)

Hopefully you just finished reading How-to on CCTV wiring.

So what is DVR and NVR. DVR are video recorders for analog cameras. NVR are video recorders for IP camera. DVR recorders cost about $200-300, the price very on type of video compression and HDD (recording time).

Since this is DIY blog I will write only about home version of recorders, the PC setup.
For analog type camera you will need to purchase one of these.
The DVR cards are split in two types: hardware or software encoding. They also come in 4 or 8 camera setup. Hardware encoders are faster since they do all encoding on DVR card, making them more expensive. Software cards use more CPU to record events and are cheaper. DVR cards come with software that can be used to display and record information from multiple cameras at the same time. These are installed in computers to allow them to function as digital video recording (DVR) systems. The quality of recording 1fps or 25fps will dictate the size of HDD that you need. Also, some encoders are better then others when it comes to video compression. NOTE: You need DVR cards only if you use analog cameras, for IP cameras you DO NOT need DVR card.

CCTV server setup (2 to 6 camera setup)
CPU: you need at least Duo Core type CPU with 2GHz speed. note: on average P4 cpu can handle 2 cams @ 5fps, with motion detection.
Memory: 2 GB at least, 4GB recommended. This has to do with pri-motion/alarm recording and if you decide to use this option. This will record 10-15 images before motion was triggered.
HHD: 500GB at least, 1TB recommended. Need to be able to record for at least 15 days. I personally use motion detection on CCTV software, so it only records once triggered and then records for 30 sec if no other motion detected.

My setup:
Windows XP, Blue Iris CCTV software, 1TB HHD, Dual Core 2.2Ghz, 4GB ram, UPS. cpu load at ideal <20% Why Blue Iris? its cheap (<$50), it works well and has web server option. This allows for mobile phone to view and monitor cams as well. Also, using BI web server and LogMe Hamachi for remote monitoring. check my other post relating to Blue Iris and remote monitoring
