So unless you are an electrician, or have significant electrical skills, you probably should not attempt to do this type of installation yourself. Because not only could it be dangerous, it could also turn into a fire hazard if it is not done right. Electricity is not something you want to take any chances with. Additionally, although you should probably stick with a wireless doorbell camera, if you want a wired doorbell camera and your landlord gives you his/her blessing which he/she might do if you have it professionally installed, it’s even more important that you not only get your landlords blessing, but that the written permission he/she gives you includes exactly what you can and can’t do as far as drilling holes in the walls, ceilings, etc. This will protect you from having to pay damages due to miscommunication when you move out. You will also need to realize that sometimes a landlord will give you permission to have a hardwired doorbell camera installed, but he/she might also require that you leave it with the rental when you move.

Another question in the effectiveness of CCTV for policing is around uptime of the system; in 2013 City of Philadelphia Auditor found that the $15M system was operational only 32% of the time. There is strong anecdotal evidence that CCTV aids in detection and conviction of offenders; indeed UK police forces routinely seek CCTV recordings after crimes. Moreover, CCTV has played a crucial role in tracing the movements of suspects or victims and is widely regarded by anti terrorist officers as a fundamental tool in tracking terrorist suspects. Large scale CCTV installations have played a key part of the defenses against terrorism since the 1970s. Cameras have also been installed on public transport in the hope of deterring crime. A more open question is whether most CCTV is cost effective.
