Thanks for the document. For the past one week I have been on field work,I realized that most of the problems we have experience on CCTV are channel to the hard drive like 1. DVR restarting by itself 2.CCTV showing offline status on desktop 3.CCTV cannot be view locally, etc Please is their a technical book or document or video that can teach me how to troubleshoot fault found on DVR/NVR/XVR/HDVR For instance, 1.hard drive issues.How the can be solve 2.some channels in the cctv is blurred 3.rebooting with flag (0*04) 4.Image view is very slow 5. The most important of all is when cctv get faulty,there was no data recorded within that period till when it is fixed, data lost cannot be retrieved Any document or technical book or videos that can help me improve CCTV troubleshooting skill

Thanks.please do we have any troubleshooting document/workbook for CCTV.

Though the company is training me,I just want to have knowledge in CCTV while am undergoing my training.Am also a graduate of Electronic and Computer Engineering, telecommunication major.hence i have knowledge in telecommunication, computer, electronic,networking and linux

I already have knowledge in Cisco networking and linux.I do go for field work also.I just want to have something to study while am acquiring experience.

I just got a new job with a security company.we do installation and maintenance of CCTV, burglar alarm,bullet proof door,etc.Am looking for any useful documents that can teach me how to install and maintain/troubleshoot CCTV.
