Situation of deprivation of liberty fact that no video-surveillance exists in the cells where immobilisations are carried out in most CPs, as mentioned above, is of particular relevance. The SGIP reported that, to the extent permitted by the budget, video-surveillance systems will be installed at those CPs at which, given their age, this is more efficient and has more favourable effects. Thus, they informed us that such systems had been installed at certain CPs such as those of Badajoz, Castellón, Cuenca, Madrid I, Melilla and Valladolid. In addition, as regards the protocol for the recording and storage of images taken by the video-surveillance systems, it was reported that an instruction to regulate video-surveillance in the penitentiary context is being prepared. In addition, at the CP of Segovia, several cameras were broken down and cuts occurred in the electricity supply interrupting the recordings. The SGIP reported that the cameras were being gradually replaced and that the breakdowns had been repaired. 142. At certain CPs, such as Puerto I (Cádiz) and Villabona (Asturias), cells did not have a centralised mechanical opening system, which would be advisable to enable an urgent and fast evacuation in emergencies, in accordance with paragraph 156 of Annual Report 2011. Nevertheless, the SGIP reported that it was currently not possible to install these systems at CPs that do not have them available given the high cost involved and the difficulty of carrying out these actions at operating CPs. 143. The age of the visited centres differed. The oldest was the CP for men of Barcelona, of 1904; it was followed by CP Puerto I (Cádiz), of 1981; the CP of Seville, of 1989; CP Villabona (Asturias), of 1991; the CP of Segovia, of 2000; the CP of Córdoba of 2002; CP Puerto III (Cádiz), of 2007; and, the most recent, CP Seville II, of 2008. The age of the facilities was obvious at the CP for men of Barcelona and CP Puerto I (Cádiz). In respect of the former, it must be mentioned that it is expected to close when so permitted by the budget. In respect of CP Puerto I (Cádiz), the following deficiencies are to be pointed out: the water pipes have a bad odour, there is an excessive presence of mosquitoes, it has no heating or air conditioning for use by inmates, certain areas were in a poor state of repair, with damp in some cells, the unit yards had no roofed area to permit their use in bad weather conditions and the cells had a squat toilet instead of an anti-vandal toilet.
